O cabelo dela revela: Towards decolonizing Afro Brazilian hair

ABSTRACT This report uses the interview form as a methodology for a postcolonial research project. The author, photographer Tau Battice, made portraits of 150 women in Brazil, also interviewing them about their hair experiences. These interviews and photographs serve as a supporting methodological tool in a larger ethnographic project concerning topics such as Blackness, chemically straightened versus natural hair, conflict between reality and image, and decolonization of the mind. A cross-section of Brazilian women of self-identified West African descent explain their changing relationship to their hair and how this impacts their subjectivities. Drawing upon Frantz Fanon and several anthropologists and ethnographers, the project investigates how natural hair was seen as “bad” by friends and family who are influenced by the white male gaze. The photographic images are a visual language of these women expressing pride in their African roots and making peace with their natural hair.

Value of CT quantification in progressive fibrosing interstitial lung disease: a deep learning approach.

To evaluate the relationship of changes in the deep learning-based CT quantification of interstitial lung disease (ILD) with changes in forced vital capacity (FVC) and visual assessments of ILD progression, and to investigate their prognostic implications. This study included ILD patients with CT scans at intervals of over 2 years between January 2015 and June 2021. Deep learning-based texture analysis software was used to segment ILD findings on CT images (fibrosis: reticular opacity + honeycombing cysts; total ILD extent: ground-glass opacity + fibrosis). Patients were grouped according to the absolute decline of predicted FVC (< 5%, 5-10%, and ≥ 10%) and ILD progression assessed by thoracic radiologists, and their quantification results were compared among these groups. The associations between quantification results and survival were evaluated using multivariable Cox regression analysis. In total, 468 patients (239 men; 64 ± 9.5 years) were included. Fibrosis and total ILD extents more increased in patients with larger FVC decline (p < .001 in both). Patients with ILD progression had higher fibrosis and total ILD extent increases than those without ILD progression (p < .001 in both). Increases in fibrosis and total ILD extent were significant prognostic factors when adjusted for absolute FVC declines of ≥ 5% (hazard ratio [HR] 1.844, p = .01 for fibrosis; HR 2.484, p < .001 for total ILD extent) and ≥ 10% (HR 2.918, p < .001 for fibrosis; HR 3.125, p < .001 for total ILD extent). Changes in ILD CT quantification correlated with changes in FVC and visual assessment of ILD progression, and they were independent prognostic factors in ILD patients. Quantifying the CT features of interstitial lung disease using deep learning techniques could play a key role in defining and predicting the prognosis of progressive fibrosing interstitial lung disease. • Radiologic findings on high-resolution CT are important in diagnosing progressive fibrosing interstitial lung disease. • Deep learning-based quantification results for fibrosis and total interstitial lung disease extents correlated with the decline in forced vital capacity and visual assessments of interstitial lung disease progression, and emerged as independent prognostic factors. • Deep learning-based interstitial lung disease CT quantification can play a key role in diagnosing and prognosticating progressive fibrosing interstitial lung disease.

Relationships of Weight Change from 20 Years of Age with the Risks of All-Cause and Cardiovascular Mortality in Patients with Chronic Kidney Disease.

Weight changes from a young age are known to be associated with poor life outcomes in the general population. However, little is known about the association between weight change from a young age and life expectancy in patients with chronic kidney disease (CKD). Data of 2,806 nondialysis CKD patients who participated in the Fukuoka Kidney Disease Registry (FKR) Study, a multicenter observational study, were analyzed. The primary outcome was all-cause death, whereas the secondary outcome was cardiovascular mortality. The covariate of interest was weight change, defined as the difference between body weight at study enrollment and at 20 years old. Cox proportional-hazards models were used to estimate the risks of mortality for participants with weight changes of ≥ 5 or ＜5 kg compared with those with stable weights. During the 5-year observation period, 243 participants died from all causes and 62 from cardiovascular disease. The risk of all-cause mortality in the weight-loss group was significantly higher than that in the stable-weight group (multivariable-adjusted hazard ratio, 2.11; 95% confidence interval [CI], 1.52-2.93). Conversely, the risk of cardiovascular mortality in the weight-loss group was significantly higher than that in the stable-weight group (multivariable-adjusted hazard ratio, 2.48; 95% CI, 1.32-4.64). However, no significant association was observed between weight gain and the risks of all-cause and cardiovascular mortalities. Weight loss from 20 years of age was found to be associated with higher risks of all-cause and cardiovascular mortalities in patients with CKD.

Неотектоника зоны перехода океан-континент в районе Кот д’Ивуара (Западная Африка)

Structural and geophysical indicators of neotectonics in the area of the continental margin of Côte d'Ivoire are represented in three interacting zones: oceanic, continental and transitional. Together with the time-varying gravitational field, they form a system in which neotectonic processes are enhanced due to their equatorial position. Seismicity is represented by dense clusters of events in the areas of junction of the Strakhov, Sao Paulo and Romansh oceanic transform faults with the continent and their overland continuation. Seismicity and gravity variations show the relationship of deep density changes to stress discharge in the area and the effect of volumetric forces on lithospheric blocks. Free air and isostasy anomalies along the shelf are segmented by the effects of vertical motions. Pull-apart depressions near the passive parts of transform faults indicate basement deformations in the interfault blocks and activation of shear displacements of dextral kinematics near the bend of the passive parts of the faults to the northeast from main oceanic azimuth. Segments with isostasy maxima on the shelf correspond to areas with coarser grain size granulometric composition, indicating leaching of fine sedimentary fraction from the bottom material.

Unlocking the power of polyphenols: A promising biomarker of improved metabolic health and anti-inflammatory diet in adolescents

Metabolic syndrome (MetS) in adolescence is a risk factor for future cardiovascular disease. The chronic inflammation associated with MetS can be attenuated by the anti-inflammatory effect of polyphenols. We aimed to evaluate total urinary polyphenols as a biomarker of anti-inflammatory diets and their effect on MetS in adolescents. In this retrospective analysis of a longitudinal cohort study, the relationship between total polyphenol excretion (TPE) in urine, the inflammatory potential of the diet measured through the Children's Dietary Inflammatory Index (C-DII), and the presence of metabolic syndrome was evaluated. The study population consisted of adolescents enrolled in the SI! Program for Secondary Schools trial, who had completed all the study forms and provided urine samples at baseline and at the two-year follow-up. Multivariate linear regression and multinominal logistic regression models were generated to evaluate the relationship of changes in TPE with changes in the C-DII score and changes in MetS status, respectively. An analysis of the ROC curve was performed to assess the potential of TPE as a biomarker of an anti-inflammatory diet. This study included 662 adolescents, 51.2% were males, and 48.8% were females, with a mean age of 12 (0.38) years at baseline. The relationship between changes in TPE and changes in the C-DII score was stratified by sex with a p-value <0.001 for the interaction. TPE and C-DII were inversely associated in males (-0.13mg GAE/g creatinine [-0.26;-0.01] per 1-SD increase, p-value=0.037). In addition, an increase in changes in TPE levels were associated with a reversal in MetS status in all adolescents (1.30 [1.27; 1.34] per 1-SD increase, p-value<0.001). The ROC curve showed that urinary TPE levels can predict dietary inflammatory potential with an AUC=0.793 (0.725; 0.863) in males. Polyphenols excreted in urine are a potential biomarker of anti-inflammatory diets in males and are associated with a reversal of MetS status in adolescents.

Increasing workforce psychological flexibility through organization-wide training: Influence on stress resilience, job burnout, and performance

There is growing interest in the role of psychological flexibility as a potential resilience factor in workplace settings for protecting employees against the risk of job burnout. This field study contributes to the literature by investigating the utility of delivering brief ACT-informed training to the entire regional workforce of an innovation and manufacturing organization. A total of 504 employees attended the training, 281 of whom completed study measures prior to the training and three months later. Across the 3-month timeframe, participants reported a statistically small and significant increase in work-related psychological flexibility. Increased psychological flexibility was associated with improved stress resilience, reduced exhaustion, and increased personal accomplishment. No change was observed on the depersonalization component of burnout or task performance. Moderation analyses revealed that residual change associations between work-related psychological flexibility and both exhaustion and resilience were stronger among participants with higher baseline exhaustion. By contrast, work-related psychological flexibility trended toward a stronger residual change relationship with personal accomplishment among participants with lower baseline exhaustion. We interpret these findings from the perspective of resource-based theories of workplace functioning, and highlight the potential of cultivating psychological flexibility as part of organization-wide personnel development initiatives.

Trends and Environmental Drivers of Marine Fish Landings in Cuba’s Most Productive Shelf Area

Marine finfish landings in Cuba have decreased during the last 30 years. However, in Cuba’s most productive fishing region, certain species, including rays, herrings, and snappers, have had increased landings over the past decade. Despite these anomalies, no comprehensive analysis of the interactions among multispecies landing dynamics, environmental factors, and fishing efforts has been carried out. This study estimates the dynamics of multispecies finfish landings between 1981 and 2017 on the southeastern coast of Cuba. A log-normal generalized additive model (GAM) was fit to evaluate the effects of various environmental and effort-related variables on the total landings. During the period analyzed, the finfish landings and fishing effort decreased by 46% and over 80%, respectively. Despite concerns about overfishing, landings per unit of effort (LPUE) increased by 2.8 times. The total fish landings were significantly related to changes in the fishing effort, coastal vegetation, rainfall, chlorophyll-a, and the Southern Oscillation Index (SOI). This study highlights the changing relationship between the landings and fishing effort, suggesting that LPUE may not accurately reflect true stock abundance. The findings of this study will assist in integrating the dynamics of finfish species, ecosystem status, and management actions for Cuba’s most productive fishing zone.

Data Discretion: Screen-Level Bureaucrats and Municipal Decision-Making

Public servants tasked with implementing rules or policies on the street level often make discretionary decisions based on local context. Lipsky has labeled them street-level bureaucrats. During the COVID-19 pandemic, as most face-to-face interactions facilitated by local government moved online, many street-level decisions were moved to screens, representing the actions of whom Bouvins and Zouridis refer to as screen-level bureaucrats. Discretionary decision making among public servants continued, but much of it centered on the collection, analysis, and use of data. This article reports on research conducted in 2021 with municipal employees in a large northeastern city in the United States, and examines their changing relationship with data in determining how and to whom they deliver services. In the context of a public health crisis, public servants exercised “data discretion” to rapidly alter services and to internally advocate for underserved populations. The specific practices of discretionary decision making are explored through candid interviews with public servants. The discussion explores how these emergent practices might persist post crisis, how discretion is counterintuitively used to build trust in government, and how data discretion is not limited only to the progressive values manifested in the example of a northeastern city.

Photovoltaic Power Prediction Based on Irradiation Interval Distribution and Transformer-LSTM

Accurate photovoltaic power prediction is of great significance to the stable operation of the electric power system with renewable energy as the main body. In view of the different influence mechanisms of meteorological factors on photovoltaic power generation in different irradiation intervals and that the data-driven algorithm has the problem of regression to the mean, in this article, a prediction method based on irradiation interval distribution and Transformer-long short-term memory (IID-Transformer-LSTM) is proposed. Firstly, the irradiation interval distribution is calculated based on the boxplot. Secondly, the distributed data of each irradiation interval is input into the Transformer-LSTM model for training. The self-attention mechanism of the Transformer is applied in the coding layer to focus more important information, and LSTM is applied in the decoding layer to further capture the potential change relationship of photovoltaic power generation data. Finally, sunny data, cloudy data, and rainy data are selected as test sets for case analysis. Through experimental verification, the method proposed in this article has a certain improvement in prediction accuracy compared with the traditional methods under different weather conditions. In the case of local extrema and large local fluctuations, the prediction accuracy is clearly improved.

Economics Imperialism then and now: Ben Fine on the Changing Relationship between Economics and the Other Social Sciences

Abstract In this review essay, I explore the first two of a planned 10 volumes of Ben Fine’s selected journal publications. The two are broadly concerned with economics imperialism before and after a ‘watershed’ (before which it is recognised for what it is and after which it is less so). I first set out what Fine means by economics imperialism. I then discuss a few examples of what heterodox economists have been talking about insofar as they were not (quite) talking about economics imperialism. This provides a useful segue into the specifics of Fine’s writings across the two volumes, and in two subsections, I separately survey the volumes. Finally, I conclude with some comment on the sense of unfinished business that hangs over constructive change.

Voices from the Shadows: Intergenerational Conflict Memory and Second-Generation Northern Irish Identity in England

Recent scholarship has highlighted the heterogeneity of second-generation Irish identities in Great Britain, yet the varieties of self-identification espoused by the English-raised children of Northern Irish parents remain almost wholly unexplored. This article redresses this neglect by examining the relationship between parentally transmitted memories of the Northern Ireland Troubles (c.1969–1998) and the forms of identity and self-understanding that such children develop during their lives in England. Drawing on original oral history testimony and using the concepts of narrative inheritance and postmemory as interpretive tools, it demonstrates the complex correlation that exists between parents’ diverse approaches to memory-sharing and their children’s negotiation of inherited conflict memory as they position themselves discursively within contemporary English society. Based on a close reading of five oral history interviews, the analysis reveals a spectrum of creative postmemory practices and identity enactments, whereby narrators agentively define themselves in relation to the meanings they attribute to inherited memories, or the dearth thereof, as they navigate their tangled transnational affinities and allegiances. The article also explores how these practices and enactments are subtly responsive to narrators’ changing relationships to their narrative inheritances as their experience and awareness of their own and their parents’ lives deepen over the life course.

Reconceptualising the EU-member states relationship in the age of permanent emergency

AbstractSince 2008, the European Union (EU) has been engulfed in several crises. While distinct, these crises are feeding into each other and are testing the capacity and resilience of EU and member states, bringing forward common policy questions and new forms of cooperation. The permanent character of this state of crisis has made analysts talk about our times as the age of permacrisis. As a result, a trend towards a new mode of ‘coordinative Europeanization’ in EU decision-making has been observed since the Covid-19 crisis. In this paper we first define the new mode of coordinative Europeanization and outline its key features. We argue that the recent crises have altered the EU member states’ relationship in pursuit of fast policy responses. We analyse the reasons behind this changing relationship as well as the possible avenues it may take. We then discuss the challenges caused by coordinative Europeanization and how it relates to pre-existing de-Europeanization tendencies. We close the paper with an analysis of the significance of our findings and we propose new avenues for research.

Association between longitudinal changes in body composition and the risk of kidney outcomes in participants with overweight/obesity and type 2 diabetes mellitus.

To assess the relationship of longitudinal changes in fat mass (FM), lean mass (LM) and waist circumference (WC) with incident kidney outcomes in people with overweight/obesity and type 2 diabetes mellitus (T2DM). A total of 3927 participants with baseline estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2 from the Look AHEAD (Action for Health in Diabetes) trial were included. The primary outcome was kidney outcomes, defined as a decrease in eGFR of at least 40% from baseline at follow-up visit, or end-stage kidney disease. During a median follow-up of 8.0 years, 450 kidney outcomes were documented after the first 1 year. In the intensive lifestyle intervention (ILI) group, reductions in FM (per 10% decrease, adjusted hazard ratio [HR] 0.80, 95% confidence interval [CI] 0.69-0.94) and WC (per 10% decrease, adjusted HR 0.72, 95% CI 0.59-0.88) from baseline to 1-year follow-up were significantly associated with a lower risk of kidney outcomes. The change in LM was not significantly associated with risk of kidney outcomes (per 10% decrease, adjusted HR 0.78, 95% CI 0.58-1.06). In the diabetes support and education group (control group), no significant association was found between changes in body composition and kidney outcomes. Similar results were observed for the 4-year changes in body composition. In this post hoc analysis of the Look AHEAD trial, longitudinal declines in FM and WC were associated with a lower risk of kidney outcomes in the ILI group in participants with overweight/obesity and T2DM.

North and South in Medieval Iberia: A historical and environmental estimate through isotopic analyses.

The Middle Ages in the Iberian Peninsula is a period of special interest for studying the relationship of climate change with historical and socioeconomic processes. Between the 8th and 15th centuries AD, the Peninsula was characterized not only by complex political, cultural, and social transitions but also by major variations in the climate. The objective of this study was to examine differences in diet and mobility between distinct populations of the Peninsula and explore the possible relationship of diet, mobility, and culture with environmental variables and geographical settings. For this purpose, we obtained stable isotopic ratios of carbon and oxygen (δ13C and δ18O) from the enamel apatite of first upper incisors from 145 individuals at eight archeological sites that represent both Christian and Islamic communities and both rural and urban social settings. Results revealed a dietary difference between Christian and Islamic populations, observing a greater contribution of C4 plants, possibly sorghum, in the diet of the latter, especially in a rural setting. The disparity in oxygen isotopic ratios between populations from the North and South of the Peninsula is consistent with modern climatic differences between these regions. In this line, intraregional variability in oxygen isotopic ratios may hint at diachronic occupation phases under varying climatic conditions. The few isotopic outliers in our sample suggest overall low mobility levels.

Bacterial identification in herniated intervertebral discs: a prospective cohort study

Reports of Cutibacterium acnes isolated in cultures of intervertebral disc samples suggest it as possibly responsible for inflammatory conditions causing Modic changes on spinal magnetic resonance imaging (MRI). Our objective was to investigate the prevalence of C. acnes in samples of intervertebral disc of patients with lumbar disc herniation; to investigate prognostic factors and the relationship of Modic changes with infection 1 year after microdiscectomy. Prospective cohort study. In this single-center study, patients consecutively operated on for disc herniation had samples of the disc, multifidus muscle and ligamentum flavum (as an indication of contamination) extracted for culture. Age, sex, alcohol and tobacco consumption, body mass index; function, pain, and Modic chances in MRI before surgery and MRI 1 year later; rate of disc, muscle and ligament infection (primary outcome); diabetes and corticoid use (confoundings). The protruded disc, muscle and ligament samples were sent for culture analysis in up to 30 minutes. A subsample of 17 patients underwent next-generation sequencing (NGS) molecular analysis too. We performed descriptive analysis and comparison of groups of patients with and without infection or contamination using Student's t, Mann-Whitney, chi-square, or Fisher's exact tests as appropriate, and pre- and postsurgical comparisons with the Wilcoxon test. From January 2018 to September 2019, 112 patients underwent open lumbar microdiscectomy, 67 (59.8%) men. Cultures showed 7 (6.3%) positive cases in the disc (2 with C. acnes), 3 (2.7%) in the ligament, and 12 (10, 7%) in muscle. No evidence of a difference in Modic alterations pre- or postoperatively was found between patients with and without positive culture 1 year after surgery. No association was found between culture positivity and functional or pain differences either. NGS results were all negative for C. acnes. We identified infective bacterial presence in the herniated disc in less than 2% of patients with disc herniation. C. acnes was not identified in any disc microbiome analysis. No significant association was observed between positivity for tissue infection and any clinical prognostic factor.

Postextrasystolic repolarization changes of ventricular premature beats correlate with structural heart disease and suggest prognostic implications

Ventricular premature beats (VPBs) can potentially lead to life-threatening arrhythmias, especially in patients with structural heart disease (SHD). However, identifying dangerous VPBs has always been a topic and challenge in clinical research. This study aimed to evaluate the relationship of postextrasystolic repolarization changes of VPBs with SHD and its possible additional prognostic value. 125 cases of frequent VPBs with SHD and 156 cases without SHD were included. VPBs were stratified selected from 24 h Holter recording according to the scale of heart rate. Average QTDV (difference value of QT interval between the first beat follow VPB with beats preceding VPB) and max QTDV were significantly longer in SHD group than that in the non-SHD group. For identifying patients with SHD, the best cutoff value were 19 ms for average QTDV (AUC = 0.931) and 29 ms for max QTDV (AUC = 0.910) respectively. For Tu morphology analysis, PT2 (postextrasystolic T wave amplitude change ≥2 mV), reversed T wave, and Pu (postextrasystolic u wave) change were all highly specific, but low sensitive as identification of SHD. Compared with average QTDV < 19 ms patients, average QTDV ≥ 19 ms patients had significantly larger left heart size and wores left cardiac function. The presence of non-persistent ventricular tachycardia runs was higher in average QTDV ≥ 19 ms group and positive Pu change group than that in control groups. The findings indicated that postextrasystolic repolarization changes of VPBs correlated with SHD and suggested potential value in prognosis asssessment.

Behavioral and Psychosocial Mediators of the Effects of Increased Self-Regulation on Short- and Long-Term Weight Loss in Women Within Community-Based Obesity Treatments.

The aim of this study was to evaluate behavioral mediators of relationships between increased self-regulation of eating and weight loss so that findings on psychosocial correlates of treatment-associated weight change could be extended. Participants were women enrolled in 6-month community-based obesity treatments using primarily self-regulatory (SR-treatment, n = 52) or education-focused (Didactic training, n = 54) methods. Changes from baseline in self-regulation of eating, self-efficacy for controlled eating, emotional eating propensity, exercise, and the diet were first calculated. There were significant overall improvements in each psychosocial and behavioral measure, and weight. Except for emotional eating change from baseline-Month 12, improvements were each significantly greater in the SR-treatment group. Mediation of the relationships of change in self-regulation with 6-, 12-, and 24-month weight changes, by changes in self-efficacy and emotional eating, were significant, R2s = .19-.26, ps < .001. Only changes in emotional eating over 6 and 12months were significant mediators. Mediations of the same self-regulation-weight change relationships by changes in exercise and the diet were also significant, R2s = .19-.28, ps < .001, and only changes in exercise over 12 and 24months were significant mediators. Although group membership did not moderate effects on weight, substitution of sweets for the (composite) diet demonstrated it to be a significant mediator over 6 and 12months. In women with obesity, self-regulation improvement was associated with short- and longer-term weight loss through changes in emotional eating, exercise, and sweets consumption. Thus, behavioral treatments will benefit from targeting those variables.

Just Fun and Games? A Sociological Consideration of Fun in Video Games

The concept of “fun” is widely used within the game design and game studies literature, and is frequently highlighted as a key component of good game design, as well as a key factor in why people play games. However, it is a term rarely unpacked, and fun in video games remains relatively underresearched, certainly in comparison to other associated terms such as “play.” This article therefore provides a much-needed sociological exploration of a term at the center of games design and studies, and moreover, argues, that doing so allows us to explore a range of important and related topics, such as the changing relationship between work and leisure and the blurring of fun and no-fun boundaries, as well as enabling us to delineate between often interchangeably used terms, such as happiness, enjoyment, and pleasure.

Comment on 'Changing relationships between HIV prevalence and circumcision in Lesotho', and 'Age-incidence and prevalence of HIV among intact and circumcised men: an analysis of PHIA surveys in Southern Africa'.

Two articles by Garenne (2023a,b) argue that voluntary medical male circumcision does not reduce human immunodeficiency virus transmission in Africa. Here we point out key evidence and analytical flaws that call into question this conclusion.
