RESUMO

In the United States, college has often served as an incubator for social change agents in the form of student activism and participation in broader social movements. Historically Black colleges and university (HBCUs) have played a pivotal role in social justice movements since their inception with the most notable example being the central role of HBCUs in the Civil Rights Movement. The role of HBCUs in cultivating exemplary leaders provides invaluable examples and frameworks for tackling the dual pandemics of COVID-19 and the latest racial reckoning. The purpose of this paper is to provide a case study of how an all-male HBCU contributes to the development of moral leadership and how that tradition has evolved with the current dual pandemics. We provide a historical overview of Morehouse's leadership models and provide a case study from students currently enrolled at Morehouse College, the only all-male, historically Black college in the United States. Student participants described how leadership has evolved from previous generations, the impact of social media, and what it means to be a moral leader and how the HBCU tradition, shapes leadership.

RESUMO

In this mixed-methods quality improvement project, we implemented and evaluated sexual orientation and gender identity (SOGI) form rollout in the electronic medical record. Families in our gender diversity program completed a baseline survey in 2017 (55/328 responded) and follow-up in 2020 (180/721 responded) to evaluate the frequency of affirmed name and pronoun use in the hospital. Survey feedback informed system-wide inclusivity efforts and training. SOGI was implemented in 2020 after 1,662 providers completed an online training and 11,090 team members completed gender and sexual orientation inclusivity training. We recommend similar trainings for health systems utilizing SOGI.

RESUMO

BACKGROUND: The American Medical Association Code of Medical Ethics states that any clinical image taken for public education forms part of the patient's records. Hence, a patient's informed consent is required to collect, share, and distribute their image. Patients must be informed of the intended use of the clinical image and the intended audience as part of the informed consent. OBJECTIVE: This paper aimed to determine whether a random selection of instructional videos containing footage of central venous catheter insertion on real patients on YouTube (Google LLC) would mention the presence of informed consent to post the video on social media. METHODS: We performed a prospective evaluation by 2 separate researchers of the first 125 videos on YouTube with the search term "central line insertion." After duplicates were deleted and exclusion criteria applied, 41 videos of patients undergoing central line insertion were searched for reference to patient consent. In the case of videos of indeterminate consent status, the posters were contacted privately through YouTube to clarify the status of consent to both film and disseminate the video on social media. A period of 2 months was provided to respond to initial contact. Furthermore, YouTube was contacted to clarify company policy. The primary outcome was to determine if videos on YouTube were amended to include details of consent at 2 months postcontact. The secondary outcome was a response to the initial email at 2 months. RESULTS: The researchers compiled 143 videos. Of 41 videos that contained footage of patient procedures, 41 were of indeterminate consent status and 23 contained identifiable patient footage. From the 41 posters that were contacted, 3 responded to initial contact and none amended the video to document consent status. Response from YouTube is pending. CONCLUSIONS: There are instructional videos for clinicians on social media that contain footage of patients undergoing medical procedures and do not have any verification of informed consent. While this study investigated a small sample of available videos, the problem appears ubiquitous and should be studied more extensively.

RESUMO

The Utah electrode array (UEA) and its many derivatives have become a gold standard for high-channel count bi-directional neural interfaces, in particular in human subject applications. The chapter provides a brief overview of leading electrode concepts and the context in which the UEA has to be understood. It goes on to discuss the key advances and developments of the UEA platform in the past 15 years, as well as novel wireless and system integration technologies that will merge into future generations of fully integrated devices. Aspects covered include novel device architectures that allow scaling of channel count and density of electrode contacts, material improvements to substrate, electrode contacts, and encapsulation. Further subjects are adaptations of the UEA platform to support IR and optogenetic simulation as well as an improved understanding of failure modes and methods to test and accelerate degradation in vitro such as to better predict device failure and lifetime in vivo.

RESUMO

OBJECTIVE: Intracortical microstimulation has shown promise as a means of evoking somatosensory percepts as part of a bidirectional brain-computer interface (BCI). However, microstimulation generates large electrical artifacts that dominate the recordings necessary for BCI control. These artifacts must be eliminated from the signal in real-time to allow for uninterrupted BCI decoding. APPROACH: We present a simple, robust modification to an existing clinical BCI system to allow for simultaneous recording and stimulation using a combination of signal blanking and digital filtering, without needing to explicitly account for varying parameters such as electrode locations or amplitudes. We validated our artifact rejection scheme by recording from microelectrodes in primary motor cortex (M1) while stimulating in somatosensory cortex of a person with a spinal cord injury. MAIN RESULTS: M1 recordings were digitally blanked using a sample-and-hold circuit triggered just prior to stimulus onset and a first-order 750 Hz high-pass Butterworth filter was used to reduce distortion of the remaining artifact. This scheme enabled spike detection in M1 to resume as soon as 740 µs after each stimulus pulse. We demonstrated the effectiveness of the complete bidirectional BCI system by comparing functional performance during a 5 degree of freedom robotic arm control task, with and without stimulation. When stimulation was delivered without this artifact rejection scheme, the number of objects the subject was able to move across a table in 2 min under BCI control declined significantly compared to trials without stimulation (p < 0.01). When artifact rejection was implemented, performance was no different than in trials that did not include stimulation (p = 0.621). SIGNIFICANCE: The proposed technique uses simple changes in filtering and digital signal blanking with FDA-cleared hardware and enables artifact-free recordings during bidirectional BCI control.

RESUMO

Through 3 studies, we investigated whether angularity and roundness present in faces contributes to the perception of anger and joyful expressions, respectively. First, in Study 1 we found that angry expressions naturally contain more inward-pointing lines, whereas joyful expressions contain more outward-pointing lines. Then, using image-processing techniques in Studies 2 and 3, we filtered images to contain only inward-pointing or outward-pointing lines as a way to approximate angularity and roundness. We found that filtering images to be more angular increased how threatening and angry a neutral face was rated, increased how intense angry expressions were rated, and enhanced the recognition of anger. Conversely, filtering images to be rounder increased how warm and joyful a neutral face was rated, increased the intensity of joyful expressions, and enhanced recognition of joy. Together these findings show that angularity and roundness play a direct role in the recognition of angry and joyful expressions. Given evidence that angularity and roundness may play a biological role in indicating threat and safety in the environment, this suggests that angularity and roundness represent primitive facial cues used to signal threat-anger and warmth-joy pairings.

RESUMO

Background/Study Context: Older adults (OA) have consistently shown lower accuracy compared with younger adults (YA) when labeling facial expressions of emotion in multiple choice tasks. However, OA do not show lower accuracy when judging psychological attributes from faces in rating tasks. The authors investigated whether the cognitive demands of multiple choice tasks yields an underestimation of OA emotion recognition ability and whether lower scores by OA in emotion recognition tasks are an instance of age-related dedifferentiated face perception. METHODS: Younger and older adults judged the emotions of faces depicting various expressions using (a) a multiple choice task and (b) a rating task with separate scales for each expression. We computed both accuracy scores and an emotion differentiation index, adapted from previous work on neural activation to different stimulus categories. RESULTS: Lower OA performance in emotion recognition do not reflect the cognitive demands of a multiple choice task, since age differences also were shown when assessing emotion expressions on independent rating scales. An index calculating differentiation of the emotion expressions supported the hypothesis that age differences in emotion recognition accuracy may reflect age-related perceptual dedifferentiation. DISCUSSION: Results are consistent with other evidence for perceptual dedifferentiation in OA, including lower OA performance in face recognition tasks, rating faces more similarly to one another on trait dimensions, and less specificity in neural activation to faces.

RESUMO

Background/Study Context: Many studies have found age-related declines in emotion recognition, with older adult (OA) deficits strongest for negative emotions. Some evidence suggests that OA also show worse performance in decoding complex mental states. However, no research has investigated whether those deficits are stronger for negative states. METHODS: The authors investigated OA (ages 65-93) and younger adult (YA; ages 18-22) performance on the Reading the Mind in the Eyes Test (RME), a well-validated measure of the ability to decode complex mental states from faces. RESULTS: The authors replicated findings showing OA deficits in this task. Using a multilevel logistic model, the authors found that the poorer performance of OA was due to worse performance on items for which a negative state was the correct answer. When analyzing each age group separately, OA scored worse on negative than positive items, whereas YA performance did not vary as a function of item valence. These age differences on the RME could not be explained by differences in lower-level visual function. CONCLUSION: These findings show that previously documented OA deficits in perceiving basic negative emotional expressions are also present in reading complex mental states.

RESUMO

Younger adults (YA) judgments of political candidates' competence from facial appearance accurately predict electoral success. Whether this is true for older adults (OA) has not been investigated despite the fact that OA are more likely to vote than YA and may respond differently to particular facial qualities. We examined whether OA and YA ratings of competence, trustworthiness, attractiveness, and babyfaceness of opposing candidates in US Senate elections independently predicted their own vote choices and actual election outcomes. OA and YA ratings of attractiveness, competence, and trustworthiness positively predicted their choices, but the effect of competence was weaker for OA. Babyfaceness negatively predicted OA, but not YA, choices. OA and YA competence ratings equally predicted the actual election winners, while OA, but not YA, attractiveness ratings did so. Trustworthy and babyface ratings did not predict actual winners. These findings have implications for understanding age differences in candidate preferences and the prediction of election outcomes.

RESUMO

BACKGROUND: Anal adenocarcinoma (AA) represents 5% to 10% of anal cancer. Little is known about its natural history and prognosis. Using population-based data, we defined the outcomes of AA relative to other anorectal malignancies. PATIENTS AND METHODS: We analyzed the Surveillance, Epidemiology, and End Results 18 database to identify patients ≥ 18 years old with AA, squamous cell carcinoma of the anus (SCCA), and rectal adenocarcinoma (RA) diagnosed between 1990 and 2011. Median overall survival (OS), 1-year, 3-year, 5-year, and 10-year OS were computed using actuarial methods. The log rank test was used to estimate the difference between Kaplan-Meier survival curves. A Cox proportional hazard regression model was used to adjust the effects of other covariates on survival, including age, year diagnosed, sex, stage, surgery, and radiation. RESULTS: Of 57,369 cases, 0.8% (n = 462) were patients with AA, 87.8% (n = 50,382) were patients with RA, and 11.4% (n = 6525) were patients with SCCA. The median age for AA was 69 years (range, 20-96 years), 66 years (range, 18-103 years) for RA, and 66 years (range, 14-104 years) for SCCA. The median OS was significantly lower for AA (33 months), compared with SCCA (118 months) and RA (68 months) (P < .01). In multivariate analysis, AA had a worse prognosis compared with SCCA (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.59-0.75; P < .01) and RA (HR, 0.68; 95% CI, 0.61-0.77; P < .01), after adjusting for age, sex, race, stage, grade, radiation, and surgery. There was a strong trend for improved survival among patients who received radical surgery (HR, 0.71; 95% CI, 0.51-1.00; P = .05). CONCLUSION: AA confers a significantly worse prognosis than SCCA and RA.

RESUMO

OBJECTIVES: We investigated whether evidence that older adults (OA) show less differentiation of visual stimuli than younger adults (YA) extends to trait impressions from faces and effects of face age. We also examined whether age differences in mood, vision, or cognition-mediated differentiation differences. Finally, we investigated whether age differences in trait differentiation mediated differences in impression positivity. METHOD: We used a differentiation index adapted from previous work on stereotyping to assess OA and YA likelihood of assigning different faces to different levels on trait scales. We computed scores for ratings of older and younger faces' competence, health, hostility, and untrustworthiness. RESULTS: OA showed less differentiated trait ratings than YA. Measures of mood, vision, and cognition did not mediate these rater age differences. Hostility was differentiated more for younger than older faces, while health was differentiated more for older faces, but only by OA. Age differences in differentiation mediated age differences in impression positivity. DISCUSSION: Less differentiation of trait impressions from faces in OA is consistent with previous evidence for less differentiation in face and emotion recognition. Results indicated that that age-related dedifferentiation does not reflect narrow changes in visual function. They also provide a novel explanation for OA positivity effects.

RESUMO

OBJECTIVE: Studying the brain in large animal models in a restrained laboratory rig severely limits our capacity to examine brain circuits in experimental and clinical applications. APPROACH: To overcome these limitations, we developed a high-fidelity 96-channel wireless system to record extracellular spikes and local field potentials from the neocortex. A removable, external case of the wireless device is attached to a titanium pedestal placed in the animal skull. Broadband neural signals are amplified, multiplexed, and continuously transmitted as TCP/IP data at a sustained rate of 24 Mbps. A Xilinx Spartan 6 FPGA assembles the digital signals into serial data frames for transmission at 20 kHz though an 802.11n wireless data link on a frequency-shift key-modulated signal at 5.7-5.8 GHz to a receiver up to 10 m away. The system is powered by two CR123A, 3 V batteries for 2 h of operation. MAIN RESULTS: We implanted a multi-electrode array in visual area V4 of one anesthetized monkey (Macaca fascicularis) and in the dorsolateral prefrontal cortex (dlPFC) of a freely moving monkey (Macaca mulatta). The implanted recording arrays were electrically stable and delivered broadband neural data over a year of testing. For the first time, we compared dlPFC neuronal responses to the same set of stimuli (food reward) in restrained and freely moving conditions. Although we did not find differences in neuronal responses as a function of reward type in the restrained and unrestrained conditions, there were significant differences in correlated activity. This demonstrates that measuring neural responses in freely moving animals can capture phenomena that are absent in the traditional head-fixed paradigm. SIGNIFICANCE: We implemented a wireless neural interface for multi-electrode recordings in freely moving non-human primates, which can potentially move systems neuroscience to a new direction by allowing one to record neural signals while animals interact with their environment.

RESUMO

We investigated conceptual overlap between literature demonstrating links between adult facial width-to-height ratio (FWHR) and behavior and that demonstrating links between infant FWHR and temperament by investigating whether babyfaceness is associated with FWHR and behavior at both ages. Babyfaceness was positively correlated with FWHR in both infants and adults. Babyfaceness also was correlated with an infant temperament that is a precursor of bolder behavior in childhood and adulthood, just as a broader infant FWHR was previously shown to be. These results call into question existing explanations for relationships between facial appearance and adult assertive or aggressive behavior. Previously, behavioral correlates of adult FWHR have been attributed to influences of pubertal testosterone, and correlates of adult babyfaceness have been attributed to compensation for undesirable stereotypes. Our findings indicate that the pre-natal developmental influences required to explain appearance-temperament relationships in infancy also should be considered as explanations for appearance-behavior relationships in adulthood.

RESUMO

Among many benefits of facial attractiveness, there is evidence that more attractive politicians are more likely to be elected. Recent research found this effect to be most pronounced in congressional districts with high disease threat-a result attributed to an adaptive disease avoidance mechanism, whereby the association of low attractiveness with poor health is particularly worrisome to voters who feel vulnerable to disease. We provided a more direct test of this explanation by examining the effects of individuals' own health and age. Supporting a disease avoidance mechanism, less healthy participants showed a stronger preference for more attractive contenders in U.S. Senate races than their healthier peers, and this effect was stronger for older participants, who were generally less healthy than younger participants. Stronger effects of health for older participants partly reflected the absence of positive bias toward attractive candidates among the healthiest, suggesting that healthy older adults may be unconcerned about disease threat or sufficiently wise to ignore attractiveness.

RESUMO

We examined older and younger adults' accuracy judging the health and competence of faces. Accuracy differed significantly from chance and varied with face age but not rater age. Health ratings were more accurate for older than younger faces, with the reverse for competence ratings. Accuracy was greater for low attractive younger faces, but not for low attractive older faces. Greater accuracy judging older faces' health was paralleled by greater validity of attractiveness and looking older as predictors of their health. Greater accuracy judging younger faces' competence was paralleled by greater validity of attractiveness and a positive expression as predictors of their competence. Although the ability to recognize variations in health and cognitive ability is preserved in older adulthood, the effects of face age on accuracy and the different effects of attractiveness across face age may alter social interactions across the life span.

RESUMO

UNLABELLED: BACKGROUND/STUDY CONTEXT: Two well-documented phenomena in person perception are the attractiveness halo effect (more positive impressions of more attractive people), and the babyface stereotype (more childlike impressions of more babyfaced people), shown by children, young adults (YA), and people from diverse cultures. This is the first study to systematically investigate these face stereotypes in older adults (OA) and to compare effects for younger and older adult faces. METHODS: YA and OA judges rated competence, health, hostility, untrustworthiness, attractiveness, and babyfaceness of older and younger neutral expression faces. Multilevel modeling assessed effects of rater age and face age on appearance stereotypes. RESULTS: Like YA, OA showed both the attractiveness halo effect and the babyface stereotype. However, OA showed weaker effects of attractiveness on impressions of untrustworthiness, and only OA associated higher babyfaceness with greater competence. There also was own-age accentuation, with both OA and YA showing stronger face stereotypes for faces closer to their own age. Age differences in the strength of the stereotypes reflected an OA positivity effect shown in more influence of positive facial qualities on impressions or less influence of negative ones, rather than vice versa. CONCLUSION: OA own-age biases, previously shown in emotion, age, and identity recognition, and OA positivity effects, previously revealed in attention, memory, and social judgments, also influence age differences in the strength and content of appearance stereotypes. Future research should assess implications of these results for age-related differences in susceptibility to appearance biases that YA have shown in socially significant domains, such as judicial and personnel decisions.

RESUMO

BACKGROUND: Previous research indicates that younger adults (YA) can identify men's tendency to be aggressive based merely on their neutral expression faces. We compared older adults (OA) and YA accuracy and investigated contributing facial cues. METHOD: In Study 1, YA and OA rated the aggressiveness of young men depicted in facial photographs in a control, distraction, or accuracy motivation condition. In Study 2, YA and OA rated how angry, attractive, masculine, and babyfaced the men looked in addition to rating their aggressiveness. These measures plus measured facial width-to-height ratio (FWHR) were used to examine cues to aggressiveness. RESULTS: Accuracy coefficients, calculated by correlating rated aggressiveness with the men's previously measured actual aggressiveness, were significant and equal for OA and YA. Accuracy was not moderated by distraction or accuracy motivation, suggesting automatic processing. A greater FWHR, lower attractiveness, and higher masculinity independently influenced rated aggressiveness by both age groups and also were valid cues to actual aggressiveness. DISCUSSION: Despite previous evidence for positivity biases in OA, they can be just as accurate as YA when it comes to discerning actual differences in the aggressiveness of young men.

RESUMO

Younger adults (YA) attribute emotion-related traits to people whose neutral facial structure resembles an emotion (emotion overgeneralization). The fact that older adults (OA) show deficits in accurately labeling basic emotions suggests that they may be relatively insensitive to variations in the emotion resemblance of neutral expression faces that underlie emotion overgeneralization effects. On the other hand, the fact that OA, like YA, show a 'pop-out' effect for anger, more quickly locating an angry than a happy face in a neutral array, suggests that both age groups may be equally sensitive to emotion resemblance. We used computer modeling to assess the degree to which neutral faces objectively resembled emotions and assessed whether that resemblance predicted trait impressions. We found that both OA and YA showed anger and surprise overgeneralization in ratings of danger and naiveté, respectively, with no significant differences in the strength of the effects for the two age groups. These findings suggest that well-documented OA deficits on emotion recognition tasks may be more due to processing demands than to an insensitivity to the social affordances of emotion expressions.

RESUMO

The human ability to perceive and understand others' suffering is critical to reinforcing and maintaining our social bonds. What is not clear, however, is the extent to which this generalizes to nonhuman entities. Anecdotal evidence indicates that people may engage in empathy-like processes when observing suffering nonhuman entities, but psychological research suggests that we more readily empathize with those to whom we are closer and more similar. In this research, we examined neural responses in participants while they were presented with pictures of human versus dog suffering. We found that viewing human and animal suffering led to large overlapping regions of activation previously implicated in empathic responding to suffering, including the anterior cingulate gyrus and anterior insula. Direct comparisons of viewing human and animal suffering also revealed differences such that human suffering yielded significantly greater medial prefrontal activation, consistent with high-level theory of mind, whereas animal suffering yielded significantly greater parietal and inferior frontal activation, consistent with more semantic evaluation and perceptual simulation.
