Panel data evidence on the effects of the COVID-19 pandemic on livelihoods in urban Côte d’Ivoire
Authors: Dupas Pascaline , Fafchamps Marcel , Lestant Eva
Published: February 2023

In early March 2020, a few cases of COVID-19 were diagnosed in Abidjan, the capital city of Côte d’Ivoire. To combat the spread of the disease, large restrictions to mobility and gatherings were introduced between mid-March and late May 2020. We collected panel survey data on over 2,500 individuals from poorer neighborhoods of the Greater Abidjan area over the period immediately before and after the start of the pandemic. We document striking drops in employment, hours worked, income, and food consumption in the first months after the onset of COVID-19, when lockdown was in place. We also find that, in response, survey respondents received more private transfers from other parts of the country, at a time when remittances from abroad fell—and that some respondents moved either temporarily or permanently. In terms of recovery, we find that subjective well-being was lower on average in December 2020 than it was at baseline. Yet, despite schools being closed between mid-March and July 2020, school enrollment suffered little: by December 2020, enrollment rates had bounced back to their baseline level. Our results finally indicate that government policies aimed at alleviating the worst effects of lockdown only reached a few people, and not necessarily those most in need.
The association between vitamin D serum levels, supplementation, and suicide attempts and intentional self-harm
Authors: Lavigne Jill E. , Gibbons Jason B.
Published: February 2023

Objectives

The purpose of this study is to determine the associations between Vitamin D supplementation, 25(OH) blood serum levels, suicide attempts, and intentional self-harm in a population of veterans in the Department of Veterans Affairs (VA).

Methods

A retrospective cohort study of US Veterans supplemented with Vitamin D. Veterans with any Vitamin D3 (cholecalciferol) or Vitamin D2 (ergocalciferol) fill between 2010 and 2018 were matched 1:1 to untreated control veterans having similar demographics and medical histories. Cox proportional hazards regression was used to estimate the time from the first Vitamin D3 (cholecalciferol) or Vitamin D2 (ergocalciferol) prescription fill to the first suicide attempt or intentional self-harm. Analyses were repeated in stratified samples to measure associations by race (Black or White), gender (male or female), blood levels (0–19 ng/ml, 20–39 ng/ml, and 40+ ng/ml), and average daily dosage.

Results

Vitamin D3 and D2 supplementation were associated with a 45% and 48% lower risk of suicide attempt and self-harm ((D2 Hazard Ratio (HR) = 0.512, [95% CI, 0.457, 0.574]; D3 HR = 0.552, [95% CI, 0.511, 0.597])). Supplemented black veterans and veterans with 0–19 ng/ml vitamin D serum levels were at ~64% lower risk relative to controls (Black Veteran HR: 0.362 [95% CI: 0.298,0.440]; 0–19 ng/ml HR: 0.359 [95% CI: 0.215,0.598]). Supplementation with higher vitamin D dosages was associated with greater risk reductions than lower dosages (Log Average Dosage HR: 0.837 [95% CI: 0.779,0.900]).

Conclusions

Vitamin D supplementation was associated with a reduced risk of suicide attempt and self-harm in Veterans, especially in veterans with low blood serum levels and Black veterans.

Mass gatherings provide conditions for the transmission of infectious diseases and pose complex challenges to public health. Faced with the COVID-19 pandemic, governments and health experts called for suspension of gatherings in order to reduce social contact via which virus is transmitted. However, few studies have investigated the contribution of mass gatherings to COVID-19 transmission in local communities. In Hong Kong, the coincidence of the relaxation of group gathering restrictions with demonstrations against the National Security Law in mid-2020 raised concerns about the safety of mass gatherings under the pandemic. Therefore, this study examines the impacts of mass gatherings on the local transmission of COVID-19 and evaluates the importance of social distancing policies. With an aggregated dataset of epidemiological, city-level meteorological and socioeconomic data, a Synthetic Control Method (SCM) is used for constructing a ‘synthetic Hong Kong’ from over 200 Chinese cities. This counterfactual control unit is used to simulate COVID-19 infection patterns (i.e., the number of total cases and daily new cases) in the absence of mass gatherings. Comparing the hypothetical trends and the actual ones, our results indicate that the infection rate observed in Hong Kong is substantially higher than that in the counterfactual control unit (2.63% vs. 0.07%). As estimated, mass gatherings increased the number of new infections by 62 cases (or 87.58% of total new cases) over the 10–day period and by 737 cases (or 97.23%) over the 30-day period. These findings suggest the necessity of tightening social distancing policies, especially the prohibition on group gathering regulation (POGGR), to prevent and control COVID-19 outbreaks.

The goal of cancer screening is to detect disease at an early stage when treatment may be more effective. Cancer screening in dogs has relied upon annual physical examinations and routine laboratory tests, which are largely inadequate for detecting preclinical disease. With the introduction of non-invasive liquid biopsy cancer detection methods, the discussion is shifting fromhowto screen dogs for cancer towhento screen dogs for cancer. To address this question, we analyzed data from 3,452 cancer-diagnosed dogs to determine the age at which dogs of certain breeds and weights are typically diagnosed with cancer. In our study population, the median age at cancer diagnosis was 8.8 years, with males diagnosed at younger ages than females, and neutered dogs diagnosed at significantly later ages than intact dogs. Overall, weight was inversely correlated with age at cancer diagnosis, and purebred dogs were diagnosed at significantly younger ages than mixed-breed dogs. For breeds represented by ≥10 dogs, a breed-based median age at diagnosis was calculated. A weight-based linear regression model was developed to predict the median age at diagnosis for breeds represented by ≤10 dogs and for mixed-breed dogs. Our findings, combined with findings from previous studies which established a long duration of the preclinical phase of cancer development in dogs, suggest that it might be reasonable to consider annual cancer screening starting 2 years prior to the median age at cancer diagnosis for dogs of similar breed or weight. This logic would support a general recommendation to start cancer screening for all dogs at the age of 7, and as early as age 4 for breeds with a lower median age at cancer diagnosis, in order to increase the likelihood of early detection and treatment.
Quantification of on-farm groundwater use under different dairy production systems in Pakistan
Authors: Farooq Muhammad Hassan , Shahid Muhammad Qamer
Published: February 2023

The objective of this study was to assess the role of production systems and management strategies on groundwater use at dairy farms in Punjab, Pakistan. In a prospective cohort observational study, 14 dairy farms were enrolled from the districts Okara and Kasur, Punjab. The farms were divided into two production systems: 1) peri urban dairy farms, PU (n = 7; herd size 35 ± 10); and 2) rural market oriented dairy farms, RM (n = 6; herd size 32 ± 6; Mean ± SD). One commercial dairy farm with Holstein cows (herd size = 60) was enrolled as a case study. Water flow meters were installed at the groundwater sources and the readings were taken fortnightly for 12 months. Results showed that the amount of daily on-farm groundwater use was higher in the PU dairy farm (117 ± 7 L/buffalo; Means ± SE) compared to the RM farm (80 ± 8). The farms having dirt floor used less water (78 ± 7) than the farms with brick floor (119 ± 9 L/buffalo). Furthermore, the farm having access to surface water used significantly less water (77 ± 10) than the farms having no such facility (120 ± 5 L/buffalo). Groundwater use was highest in July (145 ± 9) and lowest in February (58 ± 15 L/buffalo). The descriptive data from a commercial dairy farm revealed that the average water use during summer months was 844 ± 81 L/cow (Mean ± SD). The current findings conclude that production system, management practices and season greatly influenced on-farm groundwater use at dairy farms.

De la gesta heroica a los “chispazos” de humor. Representaciones de Hernán Cortés en la prensa de la Ciudad de México (1900-1910)
Authors: Fernández Fernández Iñigo
Published: February 2023

Como conquistador de México, Hernán Cortés ha sido una figura polémica en la historia y en la prensa mexicanas. Plantearemos un panorama de lo que los periódicos de la Ciudad de México publicaron sobre él entre 1900 y 1910 para responder a los siguientes cuestionamientos: ¿qué es lo que se escribía sobre Cortés?, ¿con qué temáticas del pasado y el “presente” fue vinculado?, y ¿qué es lo que pretendían las publicaciones con ello? Por medio de la teoría del Framing revisaremos, segmentaremos y estudiaremos un corpus documental de artículos periodísticos para evidenciar un proceso de distensión en torno a su figura como sujeto periodístico en el que, sin negar las discusiones del pasado, aunque sí matizándolas, empezó a ser relacionado más a cuestiones anecdóticas y un tanto triviales como consecuencia de un cambio en el encuadre por parte de los periódicos que se hallaba cercano con la agenda gubernamental mexicana.

Noncommunicable diseases (NCDs) have become globally abundant, yet the therapeutics we use for them are imprecise. In parallel, identifying new treatments has become more costly than ever due to the ever-aggravating efficacy crisis drug discovery faces. What unites these failures is our ontological classification of diseases, primarily based on descriptive terms. To achieve precision diagnosis and precision therapy in clinical practice, NCDs need to be redefined and subdivided based on their causal molecular mechanisms. However, the inconsistency and incompatibility of the current disease classification systems hinder data integration and analysis towards the characterization of such mechanisms. Here, we explain flaws in the current disease definitions and the dispersion among existing ontologies with the aim of establishing a mechanism-based classification of diseases hence, precision medicine.

Ann Oakley, pioneering social researcher for nearly 60 years, is Professor of Sociology and Social Policy at IOE (Institute of Education), UCL’s Faculty of Education and Society (University College London, UK). This article explores the innovation and influence of her work and the work of her close colleagues at the Social Science Research Unit (SSRU) and its Evidence for Policy and Practice Information and Coordinating Centre (EPPI-Centre). It describes advances in research and knowledge that have their roots in listening to what women have to say about their lives. The resulting novel research methods have straddled academic boundaries – between qualitative and quantitative methodologies, between disciplines, and between academia and wider society – to enhance understanding of complex social issues and approaches to addressing them within the public sector. The impact of this work is seen in terms of influencing science, knowledge management, policy decisions, professional practice and the general public. These achievements come from approaches that are outward looking and straddle academic disciplines to produce evidence that is relevant to policymaking and to practice, with the ultimate aim being to improve day-to-day life.
Adaptive control system for the water temperature at the outlet of the waste boiler
Authors: Lysenko Dmitiy S.
Published: February 2023

The experience of developing an adaptive system for controlling the temperature of network water at the outlet of a waste heat boiler is considered. When developing an adaptive control system, a number of sequential control problems were solved: creating a nonlinear model of a waste heat boiler based on a recurrent neural network, studying the frequency characteristics of a neural network model, identification structure and parameters of a control object, synthesizing a typical controller, creating an algorithm for adapting the parameters of a typical controller based on a fuzzy logic. A waste heat boiler is considered as a control object. The control object is represented by a multidimensional thermodynamic system with non-linear characteristics. Training and verification of the neural network model was carried out on the data obtained during the operation of the boiler. Identification of the structure and parameters of the control object is carried out according to the frequency response of the neural network model of the boiler. The algorithm for adapting the parameters of a typical controller contains sets of parameters of a typical controller for different states of the system with different bandwidths. The article presents a description of the stages of synthesis of an adaptive control system, the results of studying a neural network model in the frequency domain, the results of identifying a control object, calculating the parameters of a typical controller for different system states, describing a fuzzy adaptation algorithm, and modeling results.
Justification of the feasibility of use of frequency converters in control stations of submersible centrifugal pumps
Authors: Starikov Alexander V. , Kazantsev Alexander  A. , Kosorlukov Igor A.
Published: February 2023

The article considers the problem of determining the conditions under which the use of a frequency converter in a submersible pump control station leads to a reduction in electrical energy costs and becomes efficient from an energy point of view. Analytical expressions are given that allow calculating the specific costs of electrical energy during artificial lift oil production for the case when the operating mode and well flow rate are provided by wellhead choke throttling. At the same time, special attention is paid to determining the rotation speed of the submersible asynchronous motor, which ensures the required location of the operating point on the pump pressure characteristic. Formulas are also given that make it possible to calculate the specific costs of electrical energy during artificial lift oil production for the case when the operating mode and well flow rate are set by the frequency converter of the control station. An analytical expression has been found to determine the rotation speed and frequency of the supply voltage, which provide the required operating point of the pump with frequency regulation of the submersible motor. It is proposed, using the above analytical expressions, to use the iterative method to calculate the pump performance, at which the specific energy costs for the production of a cubic meter of liquid will be equal both in the case of using a frequency converter in the control station and without it. An example of calculating such a boundary value of pump performance for a hypothetical well is given. It is shown that a decrease in the required flow rate relative to the limiting value of the pump performance leads to a decrease in the specific consumption of electrical energy during artificial lift oil production in the case of using a frequency converter in the submersible pump control station.
Accurate stratification between VEXAS syndrome and differential diagnoses by deep learning analysis of peripheral blood smears
Authors: Chabrun Floris , Lacombe Valentin , Dieu Xavier , Geneviève Franck , Urbanski Geoffrey
Published: February 2023

Objectives

VEXAS syndrome is a newly described autoinflammatory disease associated with UBA1 somatic mutations and vacuolization of myeloid precursors. This disease possesses an increasingly broad spectrum, leading to an increase in the number of suspected cases. Its diagnosis via bone-marrow aspiration and UBA1-gene sequencing is time-consuming and expensive. This study aimed at analyzing peripheral leukocytes using deep learning approaches to predict VEXAS syndrome in comparison to differential diagnoses.

Methods

We compared leukocyte images from blood smears of three groups: participants with VEXAS syndrome (identified UBA1 mutation) (VEXAS); participants with features strongly suggestive of VEXAS syndrome but without UBA1 mutation (UBA1-WT); participants with a myelodysplastic syndrome and without clinical suspicion of VEXAS syndrome (MDS). To compare images of circulating leukocytes, we applied a two-step procedure. First, we used self-supervised contrastive learning to train convolutional neural networks to translate leukocyte images into lower-dimensional encodings. Then, we employed support vector machine to predict patients’ condition based on those leukocyte encodings.

Results

The VEXAS, UBA1-WT, and MDS groups included 3, 3, and 6 patients respectively. Analysis of 33,757 images of neutrophils and monocytes enabled us to distinguish VEXAS patients from both UBA1-WT and MDS patients, with mean ROC-AUCs ranging from 0.87 to 0.95.

Conclusions

Image analysis of blood smears via deep learning accurately distinguished neutrophils and monocytes drawn from patients with VEXAS syndrome from those of patients with similar clinical and/or biological features but without UBA1 mutation. Our findings offer a promising pathway to better screening for this disease.
The European Register of Specialists in Clinical Chemistry and Laboratory Medicine: code of conduct, version 3 – 2023
Authors: Queraltó Josep , Brady Jennifer , Carobene Anna , Homšak Evgenija , Wieringa Gijsbert
Published: February 2023

Whilst version 2 focussed on the professional conduct expected of a Specialist in Laboratory Medicine, version 3 builds on the responsibilities for ethical conduct from point of planning to point of care. Particular responsibilities that are outlined include:

–

The need for evidence when planning a new service, providing assurance that a new test does not do harm

–

Maintaining respect for patient confidentiality, their religious/ethnic beliefs, the need for informed consent to test, agreement on retrospective use of samples as part of governance envelopes in the pre-analytical phase

–

Ensuring respect for patient autonomy in the response to untoward results generated in the analytical phase

–

Supporting the safety of patients in the post-analytical phase through knowledge-based interpretation and presentation of results

–

The duty of candour to disclose and respond to error across the total testing process

–

Leading initiatives to harmonise and standardise pre-analytical, analytical and post-analytical phases to ensure more consistent clinical decision making with utilisation of demand management to ensure more equitable access to scarce resources

–

Working with emerging healthcare providers beyond the laboratory to ensure consistent application of high standards of clinical care

In identifying opportunities for wider contributions to resolving ethical challenges across healthcare the need is also highlighted for more external quality assurance schemes and ethics-based quality indicators that span the total testing process.

Barriers to research opportunities among osteopathic medical students
Authors: Ho Angela , Auerbach Alyssa , Faulkner Jantzen J. , Guru Satvinder K. , Lee Amber , Manna David
Published: February 2023

Context

Despite the increase of importance placed on research, both by residency program directors and the medical field at large, osteopathic medical students (OMS) have significantly fewer research experiences than United States (U.S.) allopathic medical students and non-U.S. international medical graduates. However, few studies have addressed this long-standing discrepancy, and none directly have focused on osteopathic medical students to assess their unique needs. The literature would benefit from identifying the barriers osteopathic medical students encounter when participating in research and understanding the currently available resources.

Objectives

To assess the barriers that OMS face when seeking research opportunities, identify resources currently available to osteopathic medical students at their respective schools, and investigate factors that contribute to an osteopathic medical student’s desire to pursue research opportunities. Additionally, to investigate osteopathic medical students’ confidence in research methodology.

Methods

A survey was created by the investigators and administered to participants over a three-month period via a GoogleForm. Research participants were surveyed for demographic information, as well as their involvement in research projects in the past, mentor availability, institutional resources, motivation to participate in research, individual barriers to participation, and confidence in their ability to do independent research. Responses were de-identified and analyzed using Microsoft Excel functions to count data and calculate percentages, as well as Pearson’s chi square analysis.

Results

After relevant exclusion, 668 responses were included. Of the students surveyed, 85.9% (574) indicated they currently and/or in the past were involved in research. More than half of the respondents that are not currently involved in research are interested in pursuing it (86.9%; 344). The primary barriers students reported facing include lack of time (57.8%; 386), feeling overwhelmed and unsure how to start (53.4%; 357), and lack of access to research (53%; 354). 34.7% (232) of students stated they either did not have resources from their school or were unsure whether these resources were available. The two most cited motivations to pursue research included boosting their residency application and/or interest in the area of study. Male gender and current research were associated with reported confidence in research ( [4, n=662]=10.6, p<0.05).

Conclusions

Findings from this study provide a synopsis of the barriers to research opportunities among osteopathic medical students. Notably, ⅓ of OMSs reported an absence or unawareness of available research resources at their osteopathic medical schools.
Iqbal, Nietzsche, and Nihilism: Reconstruction of Sufi Cosmology and Revaluation of Sufi Values inAsrar-i-Khudî
Authors: Yılmaz Feyzullah
Published: February 2023

While the problem of nihilism is derived from a particular historical and intellectual context in Western philosophy, i.e., the pantheism controversy in modern German philosophy and the ideas of Nietzsche, non-Western thinkers also engaged with it and developed responses to it. In this article, I am interested in analyzing Muhammad Iqbal’s (1877–1938), a leading Muslim thinker (a Sufi) from India, engagement with the problem of nihilism and his response to it from a Sufi perspective. Arguing that the existing literature on Iqbal fails to understand the deeper impact of Nietzsche’s ideas on Iqbal’s philosophy and the dramatic role “the problem of nihilism” played in causing changes in Iqbal’s philosophy, or on Iqbal’s intellectual development, in this article, I analyze how Iqbal’s encounter with the ideas of Nietzsche during his study period in Europe between 1905 and 1908 has introduced him to the problem of nihilism in its Nietzschean form, how this led Iqbal to a nihilistic mood/crisis from 1909 to 1913, and then how he later developed a response to nihilism by reconstructing the Sufi cosmology and by revaluating the Sufi values of the pantheistic/Persian type of Sufism – the outcome of which is found in his philosophical poemAsrar-i-Khudî(1915).
Is There a Dualistic Protection System for Migrant Domestic Workers? The "Easy" and "Speedy" Ratification of the ILO Convention on Decent Work for Domestic Workers in Italy
Authors: Miyazaki Rie
Published: February 2023

Domestic workers provide a variety of services and contribute significantly to the global economy. However, domestic work has long been undervalued in the labour market. In January 2013, Italy became the first country in Europe, and the first among the countries receiving migrant domestic workers, to ratify International Labour Organization Convention No. 189, the Domestic Workers Convention. In contrast to the unprecedented dedication to domestic workers’ labour rights specified in C189, the majority of domestic workers presently in Italy are migrant women and undeclared workers. This article draws on interviews to show how Italy’s ratification of C189 was accomplished through well-organised tripartism and top-down ratification processes, while perpetuating the undervaluation of the work status of migrant domestic workers.

Predictive Equations to Estimate Relative Load Based on Movement Velocity in Males and Females: Accuracy of Estimation for the Smith Machine Concentric Back Squat

Mendonca, GV, Fitas, A, Santos, P, Gomes, M, and Pezarat-Correia, P. Predictive equations to estimate relative load based on movement velocity in males and females: accuracy of estimation for the Smith machine concentric back squat. J Strength Cond Res 37(8): 1559–1565, 2023—We sought to determine the validity of using the Smith machine bar velocity to estimate relative load during the concentric back squat performed by adult male and female subjects. Thirty-two subjects (16 men: 23.3 ± 3.8 and 16 women: 26.1 ± 2.7 years) were included. The load-velocity relationship was extracted for all subjects individually. Mean concentric velocity (MCV), combined with sex, was used to develop equations predictive of relative load (% one repetition maximum [1RM]). Prediction accuracy was determined with the mean absolute percent error and Bland-Altman plots. Relative strength was similar between the sexes. However, male subjects exhibited faster concentric MCV at 1RM (p < 0.05). Mean concentric velocity and the sex-by-MCV interaction were both significant predictors of %1RM (p < 0.0001), explaining 89% of its variance. The absolute error was similar between the sexes (men: 9.4 ± 10.0; women: 8.4 ± 10.5, p > 0.05). The mean difference between actual and predicted %1RM in Bland-Altman analysis was nearly zero in both sexes and showed no heteroscedasticity. The limits of agreement in both men and women were of approximately ±15%. Taken together, it can be concluded that sex should be taken into consideration when aiming at accurate prescription of relative load based on movement velocity. Moreover, predicting relative load from MCV and sex provides an error of approximately 10% in assessments of relative load in groups of persons. Finally, when used for individual estimations, these equations may implicate a considerable deviation from the actual relative load, and this may limit their applicability to training conditions in which extreme accuracy is required (i.e., more advanced lifters and athletes).

Aben, HGJ, Hills, SP, Higgins, D, Cooke, CB, Davis, D, Jones, B, and Russell, M. The efficacy of a multimodal recovery strategy implemented after a high-intensity rugby league training session. J Strength Cond Res 37(8): 1634–1642, 2023—The efficacy of a multimodal recovery strategy implemented within 4 hours of rugby league (RL) training was investigated using repeated-measures, randomized, crossover methods in 10 professional academy RL players (age: 17 ± 1 years). Following standardized training (5,383 m covered, 350-m high-speed running, 28 repeated high-intensity efforts, 24 collisions), players completed a multimodal recovery (REC) strategy (i.e., ∼640 kcal meal + ∼1,285 kcal snacks or drinks, cold-water immersion, sleep hygiene recommendations) or control (i.e., ∼640 kcal meal: CONT) practices. Isometric mid-thigh pulls (IMTP), countermovement jumps (CMJ), and wellness questionnaires were completed before (−3 hours) and after (+24, +48 hours) training. The recovery strategy influenced IMTP peak force (p = 0.026), but between-trial differences were undetectable. No other between-trial effects (all p > 0.05) were seen for IMTP, CMJ, or wellness variables. Training-induced reductions in CMJ peak power (−4 ± 6% vs baseline: 4,878 ± 642 W) at +24 hours (p = 0.016) dissipated by +48 hours. Fatigue and lower-body soreness reduced by 16 ± 19% (p = 0.01) and 32 ± 44% (p = 0.024) at +48 hours versus +24 hours, respectively. Relative to CONT (i.e., posttraining nutrition), the effects of a single bout of recovery practices appeared limited when implemented after RL-specific training. Therefore, when training included limited collisions, balanced postexercise meals appeared equally effective relative to a multimodal recovery strategy. Transient changes in performance and wellness variables after training may have implications for practitioners. Consecutive training sessions, including a high frequency and intensity of eccentric muscle actions, should be carefully planned, especially near match-play.
Hermeneutic Inquiry: A Research Approach for Postmodern Therapists
Authors: Chang Jeff
Published: February 2023

This paper introduces hermeneutic philosophy and inquiry to postmodern therapists. Hermeneutic inquiry is an approach to research that posits that all understanding is interpretation, and interpretation is constructed in language. It shares a common view of language with postmodern therapies, and therefore is likely to be a congenial and accessible approach to research for postmodern therapists. This paper describes one example of hermeneutic inquiry and discusses some practical implications of a hermeneutic approach to inquiry.
Situating Psychopathy Within the DSM-5 Alternative Model of Personality Disorders (AMPD) Among Italian Community-Dwelling Adults
Authors: Palumbo Isabella M. , Sica Claudio , Patrick Christopher J. , Latzman Robert D.
Published: February 2023

Given growing evidence for a joint hierarchical framework of clinical and personality symptomatology, situating triarchic traits within this model would acknowledge transdiagnostic trait-related variance and provide a basis for linking the DSM-5 Alternative Model of Personality Disorders (AMPD) domains to established indicators of these neurobehavioral traits. The current study (N = 2,041 Italian adults) sought to replicate and extend recent evidence regarding the locations of triarchic traits within the AMPD and to examine relations with criterion measures at different levels of the hierarchy. “Bass-ackwards” analyses revealed a hierarchical structure of personality pathology in which triarchic traits aligned with broad dispositional domains of the AMPD. Boldness, meanness, and disinhibition were clearly situated within the Externalizing branch of the hierarchy and helped to differentiate the Negative Affect, Antagonism, Detachment, and Disinhibition domains at lower levels. The current findings support the view of psychopathy as multidimensional and encompassing developmentally meaningful and neurobehaviorally relevant traits.
Neurons in Primate Area MSTd Signal Eye Movement Direction Inferred from Dynamic Perspective Cues in Optic Flow
Authors: DiRisio Grace F. , Ra Yongsoo , Qiu Yinghui , Anzai Akiyuki , DeAngelis Gregory C.
Published: February 2023

Smooth eye movements are common during natural viewing; we frequently rotate our eyes to track moving objects or to maintain fixation on an object during self-movement. Reliable information about smooth eye movements is crucial to various neural computations, such as estimating heading from optic flow or judging depth from motion parallax. While it is well established that extraretinal signals (e.g., efference copies of motor commands) carry critical information about eye velocity, the rotational optic flow field produced by eye rotations also carries valuable information. Although previous work has shown that dynamic perspective cues in optic flow can be used in computations that require estimates of eye velocity, it has remained unclear where and how the brain processes these visual cues and how they are integrated with extraretinal signals regarding eye rotation. We examined how neurons in the dorsal region of the medial superior temporal area (MSTd) of two male rhesus monkeys represent the direction of smooth pursuit eye movements based on both visual cues (dynamic perspective) and extraretinal signals. We find that most MSTd neurons have matched preferences for the direction of eye rotation based on visual and extraretinal signals. Moreover, neural responses to combinations of these signals are well predicted by a weighted linear summation model. These findings demonstrate a neural substrate for representing the velocity of smooth eye movements based on rotational optic flow and establish area MSTd as a key node for integrating visual and extraretinal signals into a more generalized representation of smooth eye movements.

SIGNIFICANCE STATEMENTWe frequently rotate our eyes to smoothly track objects of interest during self-motion. Information about eye velocity is crucial for a variety of computations performed by the brain, including depth perception and heading perception. Traditionally, information about eye rotation has been thought to arise mainly from extraretinal signals, such as efference copies of motor commands. Previous work shows that eye velocity can also be inferred from rotational optic flow that accompanies smooth eye movements, but the neural origins of these visual signals about eye rotation have remained unknown. We demonstrate that macaque neurons signal the direction of smooth eye rotation based on visual signals, and that they integrate both visual and extraretinal signals regarding eye rotation in a congruent fashion.
Shedding the Shards of Expectations

In my first years of contingency, I began having anxiety-ridden dreams. The most prominent one featured me with shattered mirror skin. As I removed the shards, I felt the pain of each one tearing away. In this article, I consider how my whiteness and my neurodivergency intersect to impact how I feel about my position as a contingent faculty. Within the whiteness of academia, my white skin provides me with solace, but when my neurodivergency or precarious position reveal themselves, my investment in whiteness becomes harmful. These tensions pull at me. As I pull each shard off, my body tries to mold into an academic. In Disidentifications, José Esteban Muñoz writes, “disidentification is a step further than cracking open the code of the majority; it proceeds to use this code as raw material for representing a disempowered politics or positionality that has been rendered unthinkable by the dominant culture.”1 As I reflect on the tensions between whiteness, neurodivergency, and contingency, I find ways to disidentify as a means of survival in an academia that has little room for neurodivergency.
A Taste for the Local

The artist, designer, and pedagogue Elena Izcue (1889–1970) was a pioneer in the field of Peruvian decorative arts and among the first to take inspiration from Peruvian pre-Hispanic motifs. Relying on those motifs, she designed an impressive collection of textiles for the famed House of Worth in Paris during the 1930s, to which she owes her international reputation. That can be considered the high point of her career; yet it nonetheless marked a retreat from the far more ambitious project that she undertook before her departure from Peru in 1927. This article aims to reconstruct that project. I argue that Izcue’s chief objective was to bring the appreciation of pre-Columbian themes and motifs out of the realm of public monumentality and into that of domestic consumption. Izcue sought, in other words, to produce decorative objects that might furnish the homes of a rising class of modest, urban, white-collar workers with both “national” designs and domestically produced materials. After analyzing Izcue’s approach to her sources of inspiration as well as the relatively limited opportunities that she had to present her vision, I discuss the prevailing social attitudes that prevented her project from being fully legible for her intended audience. In the article’s concluding section, I assess the significance of Izcue’s aesthetic recuperation of the pre-Columbian past against the backdrop of both the official and contestatory indigenisms that rose to prominence in Peru during the twenties.
“They Had Fiery Eyes”
Authors: Nygren Barnaby
Published: February 2023

The mid-sixteenth-century La Casa del que Mató al Animal (Puebla, Mexico) is distinguished by its sculpted doorway, the jambs of which depict two hunters holding chained dogs attacking animals. Likely derived from European tapestries or prints, the work was sculpted by Indigenous artists working for the Spanish owner. A popular legend (first documented in the middle of the nineteenth century) developed around the work, linking its iconography to a story in which a young soldier, motivated by love, was said to have defeated a giant serpent that appeared in Puebla. Clearly, however, the work itself does not support such a reading. This paper, then, will address the appeal of this legend and, more significantly, the period meaning of the work. By placing it in the context of other domestic decoration from the New World and concerns relating to the political narratives of power, status, and conquest, I argue for a connotative reading of the work’s hunting and canine iconography attentive to understandings of the social and political meaning of the Spanish conquest in the period after the passing of the Nuevas leyes(New Laws on the treatment and preservation of the Indians) in 1542, the abolishment of the ayuda (the grant of Indigenous labor from Cholula, Tlaxcala, and elsewhere) in Puebla in 1545, and the Valladolid debate (1550–51) on the rights and treatment of the Indigenous people of the Americas. The work will be read as a powerful expression of conquistadorial ideology (via the work’s connection to the important local leader Gonzalo Díaz de Vargas) at a time when this ideology was under increasing pressure.

Herein, we have inquired the structural, electronic and thermoelectric properties of the couple of chalcopyrite structured solids LiAlX2 (X=S and Se) with the help of density functional theory (DFT), which is tracked by resolution of the Boltzmann transport equation with the constant relaxation time calculations. The LDA (Localized Density Approximation), PBE (Perdew-Burke-Ernzerhof), PBEsol (PBE functional revised for solids) and WC (Wu-Cohen) exchange correlation potentials have been used. The calculated lattice constants a = 5.271 Å; c = 10.178 Å and a = 6.226 Å; c = 12.165 Å for LiAlS2 and LiAlSe2 respectively and the band gap of the mentioned compounds are found in range from 1.74 eV to 3.13 eV. The dependency of thermoelectric parameters are calculated with different temperature (300-800K) and carrier concentration 1018 1019 cm-3 . From the study of ZT (figure of merit’s ZT= S2 σT/κ the dimensionless parameter) and it is found that it’s value for both the compounds in n-type as well as in p-type region is ‘unity’. Since these compounds can be the promising candidate for thermoelectric devices also these compounds are non-toxic, eco-friendly and good alternative for the green and renewable source of electric power generators.

This study aims to know the experience of family caregivers responsible for the peritoneal dialysis procedure at home. Qualitative search conducted with eight family caregivers of patients who had peritoneal dialysis at home, linked to a clinic in Rio Grande do Sul. The data collection happened through a semi-structured interview between April and May 2009. The data was submitted to thematic analysis from which three categories emerged: conditions that impose the responsibility with peritoneal dialysis; the complexity of care; and the changes in the routine of family caregivers. The responsibility in the peritoneal dialysis procedure modifies meaningfully the life of family caregivers. It is up to the health professionals to seek strategies to work according to the patient’s and the caregiver’s reality with the purpose of minimizing the impact on these people’s lives.

Venous ulcers require complex treatment and are responsible for significant morbidity and mortality rates. This study aims at identifying aspects validated by the jury for the preparation of an assistance protocol for venous ulcer sufferers. It is a descriptive and quantitative research, with 39 professionals (30 nurses, 7 doctors and two physiotherapists), held at the Onofre Lopes University Hospital, between April and July/2010. Data collection began through a questionnaire checklist. Analysis was performed through Statistical Package for Social Science 15.0, assessing compliance with guidelines. Results were the compositional aspects of the protocol: assessment of patient and lesion history/documentation, wound care/perilesional skin, dressing suggestion, use of antibiotics and pain treatment, surgical treatment/medication, improving venous return and relapse prevention, patient referral, professional training and referral/counter-referral. It was concluded that to compose the protocol, aspects related to diagnosis, treatment and injury prevention must be considered.

The objective was to identify the perceptions and experiences in relation to maternal care during hospitalization feeding of preterm infants in the Neonatal Intensive Care Unit and after discharge. Qualitative approach, exploratory-descriptive, using semi-structured interviews, aimed to address the lived experience of eleven mothers who gave birth to their babies. The interviews were conducted in the homes of mothers, between the months of June and October 2009. Through an analysis and interpretative understanding, the results indicated difficulties inter-subjective communication with professionals and the occurrence of significant early weaning with the introduction of porridge and other foods potentially harmful to the health of preterm infants. It was clear that mothers need to be accommodated in formal advisory groups during and after hospitalization, receiving structured information about feeding practices to establish the most appropriate health care for their children.
