Intentions, Methods, and the Future of Global South Studies
Authors: López Alfred J. 
Published: August 2021

Abstract
This article presents two sets of questions and a provisional hypothesis, which attempt to frame the present and possible futures of what we now call “Global South studies.” First, a broad, conceptual set of questions about the act of setting out as a setting-to-work, informed by Edward Said's meditations in Beginnings (1975) about the play between intention and method that sets epistemological parameters for an object of study, which in turn narrows the range of possible methods of knowing that object. Second, bringing this frame of “beginnings” (in Said's formula, intention + method) to bear upon a range of disciplinary methods that have shown varying degrees of efficacy as tools [techne] for scholarship of the Global South, while also revealing the possibilities and pitfalls we face as a self-described “interdisciplinary” field. I do not write in terms of a “methodology,” but rather a plurality of overlapping methods that share a common object. Third, provisional benchmarks for a more intersubjective and Southern interdisciplinarity for Global South studies, one that will not necessarily transcend the strengths and limitations of particular methods but may enable a more mindful relationship with the populations about and alongside which we would speak.
Conscience and Conscious in the Global South: B.R. Ambedkar, Kwame Nkrumah, and Anticolonial Sociology
Authors: Elam J. Daniel 
Published: August 2021

Abstract
By reading Pan-African writing with anti-caste writing together, this article examines the uses of “conscience” and “consciousness” across Third World solidarity movements. By drawing out the relationship between “consciousness” and “conscience” in political writing, this essay reveals the intertwined intellectual genealogies of Global South political theory. This genealogy is indebted to sociological projects in the early twentieth century. This article focuses particularly on Ghanaian Pan-Africanist Kwame Nkrumah and Indian anti-caste activist B.R. Ambedkar. By connecting these the two thinkers, and by tracing their shared intellectual genealogies, I illuminate the sociological experimentation at the center of anticolonial philosophy. For early twentieth-century sociology, these were normative claims about “society” as a heteronomous and egalitarian collective. By tracing these experimentations through the Global South, I show that the most ground-breaking sociologists in the North Atlantic world were, in fact, anticolonial thinkers who used the field to reimagine human emancipation.

2021/18 Fixed-term singers not comparable to permanent singers at the Royal Danish Theatre (DK)
In a recent case, the Danish Supreme Court addressed the question of what constitutes a comparable permanent employee in relation to discrimination against fixed-term employees. The Supreme Court ruled that even though the two groups of fixed-term and permanent singers at the Royal Opera Chorus of the Royal Danish Theatre performed almost the same tasks, their positions were not comparable as the singers’ qualifications and skills were different and, for this reason, the difference in terms and conditions was not discriminatory.

Published: August 2021

La correcta identificación de las emociones básicas (alegría, miedo, asco, tristeza, sorpresa e ira) desempeñan un importante papel en las relaciones sociales y conductas ligadas a la propia supervivencia. En la Enfermedad de Alzheimer (EA) la capacidad de reconocimiento emocional podría estar ya alterada en fases iniciales. Por ello, el objetivo principal del presente trabajo fue realizar una revisión sistemática de la literatura acerca del reconocimiento facial en personas con EA, identificando posibles variables moduladoras. Se realizó una búsqueda en las bases de datos Web of Science y PsycINFO. Después de aplicar los criterios de inclusión-exclusión se seleccionaron un total de 28 artículos. Las imágenes estáticas fueron los estímulos más utilizados para evaluar el reconocimiento de las emociones básicas, especialmente las fotografías desarrolladas por Paul Ekman y colaboradores. Los resultados de la revisión indican que en las personas con EA generalmente muestran déficit del reconocimiento emocional aunque los datos no son concluyentes, lo que podría estar relacionado con la diversidad de metodologías aplicadas. En relación con las variables evaluadas (sexo y edad) se pone de manifiesto la necesidad de futuras investigaciones que estudien de forma sistemática cómo estos factores pueden modular el reconocimiento emocional en pacientes con Enfermedad de Alzheimer.
The correct identification of basic emotions (joy, fear, disgust, sadness, surprise and anger) plays an important role in social relationships and behaviors linked to one´s survival. In Alzheimer´s disease (AD) the ability to recognize emotions may already be impaired at early stages of the disease. Therefore, the main objective of the present study was to carry out a systematic review of the literature on facial emotional recognition in people with AD, identifying possible modulating variables. A search in the Web of Science and PsycInfo databases was carried out. After applying the inclusion-exclusion criteria, a total of 28 articles were selected. Static images were the most used stimuli to evaluate the recognition of basic emotions, especially the photographs developed by Paul Ekman and collaborators. Results of the present review indicate the people with AD generally display deficits in emotional recognition although the data are not conclusive, which could be related to the diversity of methodologies applied. In relation to the variables evaluated (sex and age) the need of further research in order to study how these factors could modulate emotional recognition in patients with Alzheimer´s disease is highlighted.

Tecnologías emergentes están dando forma al mundo del trabajo, creando así una industria cada vez más digital, también conocida como "Industria 4.0". Por tanto, examinar el requirimiento de habilidades se vuelve esencial para facilitar la adaptación organizacional a esta revolución tecnológica. El objetivo de este estudio fue explorar la percepción de las habilidades requeridas por los trabajadores de una empresa manufacturera altamente tecnológica. En el Estudio 1 (n = 671), se realizó un análisis factorial exploratorio para identificar grupos relevantes de habilidades. Un año después, en el Estudio 2 (n = 176), confirmamos la estructural factorial a través de un análisis factorial confirmatorio y realizamos un análisis de curva de crecimiento latente para examinar posibles cambios en las habilidades requeridas debido al confinamiento y el trabajo remoto forzado durante la pandemia del COVID-19. Los resultados mostraron que las habilidades cognitivas, funcionales del negocio, estratégicas y de gestión de personas se consideran recursos importantes para la industria 4.0, siendo las habilidades funcionales del negocio más relevantes en el tiempo 2. Además, identificamos diferencias entre gerentes y subordinados con respecto a tales habilidades. Discutimos las implicaciones teóricas y prácticas para el desarrollo de habilidades en la era digital.
Emerging technologies are shaping the world of work, thus creating an increasingly digital industry, also known as “Industry 4.0”. Thus, examining skill requirements becomes essential to facilitate organizational adaptation to this technological revolution. The aim of this study was to explore the perception of skill requirements of workers of a highly technological manufacturing company. In Study 1 (n = 671), an exploratory factor analysis was carried out to identify relevant groups of skills. A year later, in Study 2 (n = 176), we confirmed the factor structure through a confirmatory factor analysis and we conducted a latent growth curve analysis to examine potential changes of the previous skill requirements due to the lockdown and the forced remote working during the COVID-19 pandemic. Findings showed that cognitive, functional business, strategic and managing people skills are considered as important resources for the industry 4.0, being the functional business skills increasingly relevant in time 2. Moreover, we identified differences between managers and subordinates regarding such skills. We discuss theoretical and practical implications for skills development in the digital age.

Corn as a staple farm produce are usually harvested at a point or time when the moisture content is more than 25% (wet.basis).,and therefore, it is easily attacked by fungi and other diseases causing organism and even physical damage, thereby reducing the market value of the crop. Drying must be carried out on those products to prevent deterioration. The objectives of this research are to develop a device that can reduce the moisture content of corn using electronic components and equally carryout evaluation on the device. Shelled corns with initial moisture content of between 25-30% (w.b.) is the major material used in this research work. A Heating element incorporated in the device supplied the needed heat which was delivered to the drying chamber by the help of a centrifugal blower. The drying experiment was carried out at three different temperature thus; 45 oC, 55 oC and 65oC. The moisture content at this varying temperature was used to determine the drying rate and the drying efficiency. The results showed clearly that the dryer air temperature affect the drying rate, the efficiency of drying, and the quality of the material. It is equally clear that the best drying rate and temperature is 65oC average 4,95% / hour, high efficient at drying temperature 55oC and 65oC equal to 86,27% and 83,51%, and best material quality with dryer temperature 55oC.

Objective: To evaluate the functional and radiological outcome of the distal femur fracture treated with a retrograde locking nail.
Methods: This is a descriptive study conducted at the Orthopedic department Dibba Hospital Fujairah, United Arab Emirates for one-year duration from March 2019 to March 2020. All patients who met the inclusion criteria were treated with femoral retrograde nailing technique. The postoperative functional score was assessed according to Schatzker and Lambert criteria, which were rated excellent, good, and poor. Radiological union was assessed by X-rays.
Results: There were 103 patients with a mean age of 35.20 ± 10.66 (range, 20 to 50 years). There were 78 men (75.72%) and 25 women (24.27%). Most of the fractures (68.9%, n = 71) were caused by car accidents. Fracture of the right side occurred in 70 (67.96%) patients, and the left side fracture in 33 (32.03%) patients. Excellent results were obtained in 75 (72.81%) patients and good results were obtained in 28 patients (28.20%). The nonunion has been documented in one patient.
Conclusion: Excellent and good functional and radiological results were obtained in patients with distal femur treated with retrograde locking nails. For some distal femoral fractures, we recommend the use of a retrograde locking nail.

Published: August 2021

SummaryTo address the difficulties of under‐actuation, nonlinearity, strong coupling, disturbances and measurement noise in four‐wheel steering (4WS) vehicle tracking control, this paper presents an innovative control strategy based on differential flatness and linear active disturbance rejection controller (LADRC). The flatness property of 4WS vehicle is derived from a simplified dynamic model that ignores some complicated dynamics and external disturbances. The impact of these neglected components on the system is treated as part of the total‐disturbance, which is estimated by the observer and compensated by LADRC. Three flatness‐based control schemes, including feedback linearization controller with PID corrective term, traditional LADRC and LADRC with robust generalized proportional integral observer (RGPIO), are designed and investigated in this paper. Moreover, an overtaking scenario is selected as an application example for the tracking controllers, and the corresponding trajectory planner is designed. The tracking performances of these schemes for the overtaking trajectory are simulated on a three‐degree‐of‐freedom dynamic model and a more complete dynamic model of the 4WS vehicle, respectively. Results show the effectiveness of these schemes, especially the excellent tracking performance of LADRC with RGPIO in the presence of strong external disturbances and measurement noise.
Asymmetric Spacer in Dion–Jacobson Halide Perovskites Induces Staggered Alignment to Direct Out‐of‐Plane Carrier Transport and Enhances Ambient Stability Simultaneously

Published: August 2021

AbstractDion–Jacobson (DJ)‐type 2D halide perovskites present superior environmental stability and a narrower bandgap, yet a contradiction between charge transport and stability remains to be resolved. Herein, it is shown that both symmetry and substitution of the organic spacer in DJ perovskites synergistically direct the narrow interlayer spacing, staggered spacer alignment, and regular phase arrangement, thereby promoting out‐of‐plane carrier transport and ambient stability. Compared to its symmetric para‐xylylenediamine (PDMA) counterpart, the asymmetric 2‐(4‐aminophenyl)ethylamine (PMEA) spacer largely aids in compressing the inorganic octahedra layer to form a non‐confinement structure with decreased exciton binding energy, while stacked benzene rings enable a staggered alignment of spacers. Such non‐confined structures are less remarkable in meta‐substituted diamine‐based DJ perovskites than those para‐ones, which retard carrier transport from 2D to quasi‐2D phases. The preferential PMEA spacer however requires a long relaxation time to form a dense and ordered staggered alignment, which is realized by a slight addition of strong‐coordinating DMSO into the DMF solvent, thus decelerating crystallization and further optimizing lamellar orientation. As a result, a best efficiency of ≈12% is achieved in (PMEA)MA3Pb4I13 based p‐i‐n type planar solar cells. Importantly, such unencapsulated devices can maintain 81% initial efficiencies after storage in ambient conditions ( ≈60% relative humidity, ≈20 °C) for 700 h.

AbstractAberrant SMAD3 activation has been implicated as a driving event in cancer metastasis, yet the underlying mechanisms are still elusive. Here, SMAD3 is identified as a nonhistone substrate of lysine acetyltransferase 6A (KAT6A). The acetylation of SMAD3 at K20 and K117 by KAT6A promotes SMAD3 association with oncogenic chromatin modifier tripartite motif‐containing 24 (TRIM24) and disrupts SMAD3 interaction with tumor suppressor TRIM33. This event in turn promotes KAT6A‐acetylated H3K23‐mediated recruitment of TRIM24–SMAD3 complex to chromatin and thereby increases SMAD3 activation and immune response‐related cytokine expression, leading to enhanced breast cancer stem‐like cell stemness, myeloid‐derived suppressor cell (MDSC) recruitment, and triple‐negative breast cancer (TNBC) metastasis. Inhibiting KAT6A in combination with anti‐PD‐L1 therapy in treating TNBC xenograft‐bearing animals markedly attenuates metastasis and provides a significant survival benefit. Thus, the work presents a KAT6A acetylation‐dependent regulatory mechanism governing SMAD3 oncogenic function and provides insight into how targeting an epigenetic factor with immunotherapies enhances the antimetastasis efficacy.

AbstractAt the microsite “Evolution Slope”, Tabigha, Israel, wild barley (Hordeum spontaneum) populations adapted to dry Terra Rossa soil, and its derivative abutting wild barley population adapted to moist and fungi‐rich Basalt soil. However, the mechanisms underlying the edaphic adaptation remain elusive. Accordingly, whole genome bisulfite sequencing, RNA‐sequencing, and metabolome analysis are performed on ten wild barley accessions inhabiting Terra Rossa and Basalt soil. A total of 121 433 differentially methylated regions (DMRs) and 10 478 DMR‐genes are identified between the two wild barley populations. DMR‐genes in CG context (CG‐DMR‐genes) are enriched in the pathways related with the fundamental processes, and DMR‐genes in CHH context (CHH‐DMR‐genes) are mainly associated with defense response. Transcriptome and metabolome analysis reveal that the primary and secondary metabolisms are more active in Terra Rossa and Basalt wild barley populations, respectively. Multi‐omics analysis indicate that sugar metabolism facilitates the adaptation of wild barley to dry Terra Rossa soil, whereas the enhancement of phenylpropanoid/phenolamide biosynthesis is beneficial for wild barley to inhabit moist and fungi pathogen‐rich Basalt soil. The current results make a deep insight into edaphic adaptation of wild barley and provide elite genetic and epigenetic resources for developing barley with high abiotic stress tolerance.

Published: August 2021

AbstractPremiseLeaf shape and size figure strongly in plants’ adaptation to their environments. Among trees, oaks are notoriously variable in leaf morphology. Our study examines the degree to which within‐tree, among‐tree, and among‐site variation contribute to latitudinal variation in leaf shape and size of bur oak (Quercus macrocarpa: Fagaceae), one of North America's most geographically widespread oak species.MethodsSamples were collected from four sites each at northern, central, and southern latitudes of the bur oak range. Ten leaf size traits were measured, and variance in these traits and eight ratios based on these traits was partitioned into tree and population components. Population means were regressed on latitude. We then parameterized a series of leaf collection simulations using empirical covariance among leaves on trees and trees at sites. We used the simulations to assess the efficiency of different collecting strategies for estimating among‐population differences in leaf shape and size.ResultsLeaf size was highly responsive to latitude. Site contributed more than tree to total variation in leaf shape and size. Simulations suggest that power to detect among‐site variance in leaf shape and size increases with either more leaves per tree (10–11 leaves from each of 5 trees) or more trees per site (5 leaves from each of 10+ trees).ConclusionsOur study demonstrates the utility of simulating sampling and controlling for variance in sampling for leaf morphology, whether the questions being addressed are ecological, evolutionary, or taxonomic. Simulation code is provided as an R package (traitsPopSim) to help researchers plan morphological sampling strategies.

Published: August 2021

AbstractEarly diagnosis of Turner syndrome (TS) enables timely intervention and may improve outcomes, but many are still diagnosed late. The objectives of our study were to describe the age and clinical features leading to diagnosis of TS in a large referral center. We hypothesize that newer testing modalities, such as noninvasive prenatal testing (NIPT), may lead to a decline in the age of diagnosis. Medical records of TS patients followed at The Cincinnati Center for Pediatric and Adult TS Care between 1997 and 2016 were reviewed for age at diagnosis, karyotype, and clinical indication(s). Patients (<18 years) were included (n = 239). Thirty‐seven percent of patients were diagnosed prenatally or neonatally (≤1 month). The median age of diagnosis was 1.5 (IQR 0.0–10.0) years. If not made during those periods, the median age was 9.3 (IQR 3.2–12.5) years. The most common indications for diagnosis were before birth, unspecified prenatal testing (57%); in neonates/infants, lymphedema (21%); in childhood, short stature (72%); and in adolescence, short stature (45%) followed by pubertal delay with short stature (22%). The age of TS diagnosis in our cohort is young. However, when the diagnosis is not made before 1 year, the median age of diagnosis has not changed in recent years. The age at diagnosis could decrease with prenatal testing, although our study may not have assessed a long enough period of increased use of NIPT. Together with an increase in provider clinical awareness, this may result in more age‐appropriate screening of comorbidities and earlier therapeutic intervention.
