Acculturation Experiences and Preterm Birth in Berlin: Does Acculturative Stress Contribute to Preterm Birth?
Authors: Lee Marlene , Pöhlmann Anna , Abou-Dakn Michael , David Matthias 
Published: April 2023

AbstractAcculturation and acculturative stress are potential risk factors for adverse perinatal outcomes. This study investigates whether and how acculturative stress affects preterm birth (PTB) in a sample of migrant women in Berlin. We interviewed 955 women who recently gave birth using standardized questionnaires (Frankfurt Acculturation Scale and Acculturative Stress Index). Multivariable logistic regression analyses assessed the effects of acculturation and acculturative stress on PTB. Women with migrant backgrounds did not have significantly higher PTB rates than German natives. First-generation migrants experienced higher acculturative stress levels than second-generation migrants, 38.8% vs. 13.2%. Acculturative stress could not be identified as a risk factor for PTB in our sample. These results need to be considered in the context of an international city and the wide use of antenatal care services in our population, which could be responsible for similarly good perinatal outcomes and highlights the potential of good access to perinatal care for vulnerable groups.

Abstract
Polychlorodibenzo-p-dioxins (PCDDs), polychlorodibenzofurans (PCDFs), and polychlorobiphenyls (PCBs) are semi-volatile compounds and can be partitioned in the atmosphere between the gas and particulate phase, due to their physicochemical properties. For this reason, the reference standard methods for air sampling include a quartz fiber filter (QFF) for the particulate and a polyurethane foam (PUF) cartridge for the vapor phase, and it is the classical and most popular sampling method in the air. Despite the presence of the two adsorbing media, this method cannot be used for the study of the gas-particulate distribution, but only for a total quantification. This study presents the results and the performance aim to validate an activated carbon fiber (ACF) filter for the sampling of PCDD/Fs and dioxin-like PCBs (dl-PCBs) using laboratory and field tests. The specificity, precision, and accuracy of the ACF in relation to the QFF + PUF were evaluated through the isotopic dilution technique, the recovery rates, and the standard deviations. Then the ACF performance was assessed on real samples, in a naturally contaminated area, through parallel sampling with the reference method (QFF + PUF). The QA/QC was defined according to the standard methods ISO 16000–13 and -14 and EPA TO4A and 9A. Data confirmed that ACF meets the requirements for the quantification of native POPs compounds in atmospheric and indoor samples. In addition, ACF provided accuracy and precision comparable to those offered by standard reference methods using QFF + PUF, but with significant savings in terms of time and costs.
Zusammenhänge zwischen nachbarschaftlicher Wohnumgebung und schulischem Bildungserfolg

Published: April 2023

ZusammenfassungOb Merkmale der nachbarschaftlichen Wohnumgebung den schulischen Bildungserfolg beeinflussen, wurde in Deutschland bislang kaum untersucht. Epidemische Theorieansätze lassen erwarten, dass Effekte der Wohnumgebung nicht linear sind, sondern erst ab bestimmten Schwellenwerten auftreten. Der Artikel untersucht den Beitrag der Sozialstruktur der Wohnumgebung zur statistischen Erklärung schulischer Kompetenzen. Dabei wird im Gegensatz zu bereits vorliegenden Arbeiten die Konfundierung von Nachbarschaftsmerkmalen mit individuellen, familiären und schulischen Merkmalen berücksichtigt. Als Datengrundlage dienen die querschnittlichen IQB-Bildungstrendstudien 2015 (N = 1467, 9. Klassenstufe) und 2016 (N = 1546, 4. Klassenstufe), die an sozialräumliche Daten des Statistischen Landesamts Bremen gekoppelt werden. Mehrebenenmodelle weisen auf einen Zusammenhang zwischen der sozialen Zusammensetzung der Nachbarschaft und den schulischen Kompetenzen von Heranwachsenden hin, der weitgehend auf die Konfundierung mit individuellen, familiären und schulischen Merkmalen zurückgeführt werden kann. Die Zusammenhänge sind linear und die Effektstärken fallen für beide Jahrgangsstufen ähnlich klein aus. Die Ergebnisse werden mit Blick auf die Folgen sozialräumlicher Segregation für Bildungsungleichheit diskutiert.
Dropping or stopping out of apprenticeships: The role of performance- and integration-related risk factors
Authors: Holtmann Anne Christine , Solga Heike 
Published: April 2023

AbstractThe dropout rate in vocational education and training (VET) programs is high in Germany. Yet, this study shows that most instances of dropout are not permanent departures from VET. Instead, most trainees later re-enter into a new training program in a different occupation or company (a phenomenon labelled “stopout”). We use Tinto’s model of college dropout, which suggests that the importance of performance-related and integration-related risk factors differs for permanent dropouts and stopouts, and their timing. Our analyses are based on longitudinal data from the National Educational Panel Study (NEPS), which provides measures for competencies and socioemotional (also called noncognitive) skills prior to starting VET programs, information to capture factors related to dis/satisfaction with training and longitudinal information on school-to-work transitions. To examine the relative importance of performance- and integration-related factors, we use Shapley decompositions. Our analyses reveal that performance-related risk factors (in terms of low math competence) increase the risk of permanently dropping out, and both cognitive and socioemotional skills predict occupational changes (occupational stopouts). Whether the VET program corresponds to the desired occupation is the most important integration-related factor, and a poor match increases the risk of both permanent dropout and occupational stopout. Moreover, lower satisfaction with training leads to changes in occupations or training companies. Finally, early training dissolutions are more strongly linked to integration-related problems, while later ones are more due to performance-related problems.
Developing Weibull-based diameter distributions for the major coniferous species in Heilongjiang Province, China
Authors: Sa Qila , Jin Xingji , Pukkala Timo , Li Fengri 
Published: April 2023

AbstractDiameter distribution models play an important role in forest inventories, growth prediction, and management. The Weibull probability density function is widely used in forestry. Although a number of methods have been proposed to predict or recover the Weibull distribution, their applicability and predictive performance for the major tree species of China remain to be determined. Trees in sample plots of three even-aged coniferous species (Larix olgensis, Pinus sylvestris and Pinus koraiensis) were measured both in un-thinned and thinned stands to develop parameter prediction models for the Weibull probability density function. Ordinary least squares (OLS) and maximum likelihood regression (MLER), as well as cumulative distribution function regression (CDFR) were used, and their performance compared. The results show that MLER and CDFR were better than OLS in predicting diameter distributions of tree plantations. CDFR produced the best results in terms of fitting statistics. Based on the error statistics calculated for different age groups, CDFR was considered the most suitable method for developing prediction models for Weibull parameters in coniferous plantations.

Published: April 2023

AbstractIdentifying potentially life-threatening diseases is a key challenge for emergency medical services. This study aims at examining the role of different prehospital biomarkers from point-of-care testing to derive and validate a score to detect 2-day in-hospital mortality. We conducted a prospective, observational, prehospital, ongoing, and derivation—validation study in three Spanish provinces, in adults evacuated by ambulance and admitted to the emergency department. A total of 23 ambulance-based biomarkers were collected from each patient. A biomarker score based on logistic regression was fitted to predict 2-day mortality from an optimum subset of variables from prehospital blood analysis, obtained through an automated feature selection stage. 2806 cases were analyzed, with a median age of 68 (interquartile range 51–81), 42.3% of women, and a 2-day mortality rate of 5.5% (154 non-survivors). The blood biomarker score was constituted by the partial pressure of carbon dioxide, lactate, and creatinine. The score fitted with logistic regression using these biomarkers reached a high performance to predict 2-day mortality, with an AUC of 0.933 (95% CI 0.841–0.973). The following risk levels for 2-day mortality were identified from the score: low risk (score < 1), where only 8.2% of non-survivors were assigned to; medium risk (1 ≤ score < 4); and high risk (score ≥ 4), where the 2-day mortality rate was 57.6%. The novel blood biomarker score provides an excellent association with 2-day in-hospital mortality, as well as real-time feedback on the metabolic-respiratory patient status. Thus, this score can help in the decision-making process at critical moments in life-threatening situations.

Abstract
Purpose
The aim of this study is to highlight the predictive role of perinatal fetal main pulmonary artery (MPA) Doppler measurements in neonatal respiratory distress syndrome development. Respiratory distress syndrome (RDS) is one of the lead causes of neonatal respiratory distress as well as neonatal death. Thus, it seems logic to evaluate fetal lung maturity before labour.

Methods
The study is a prospective cohort study performed in tertiary hospital over a period of one-year duration. 70 pregnant ladies between 34 and 38 weeks of gestation were referred for fetal echo, when pregnancy was considered a high risk. A trained radiologist using dedicated ultrasound machine with updated obstetric and fetal echo software performed the fetal echo. Doppler mode and curvilinear probe of 5.7 MHz transducer. Pediatric neonatologist observed the neonatal outcome post-natally.

Results
A total of 70 pregnant patients with risk factors underwent fetal echo, 26/70 (37.1%) were diagnosed with RDS conforming to the neonatal criteria. The mean acceleration time/ejection time ratio (At/Et ratio) of the fetal pulmonary artery was significantly reduced in fetuses that subsequently developed RDS than those without RDS. Contrarily, the mean pulsatility index (PI), resistance index (RI), and peak systolic velocity (PSV) of the fetal pulmonary artery were significantly high in fetuses who later developed RDS than in those who did not.

Conclusion
Fetal MPA Doppler measurements have a major role in anticipating the development of neonatal RDS in preterm and early term neonates.
A new fuzzy support vector machine with pinball loss
Authors: Verma Ram Nayan , Deo Rahul , Srivastava Rakesh , Subbarao Naidu , Singh Gajendra Pratap 
Published: April 2023

AbstractThe fuzzy support vector machine (FSVM) assigns each sample a fuzzy membership value based on its relevance, making it less sensitive to noise or outliers in the data. Although FSVM has had some success in avoiding the negative effects of noise, it uses hinge loss, which maximizes the shortest distance between two classes and is ineffective in dealing with feature noise near the decision boundary. Furthermore, whereas FSVM concentrates on misclassification errors, it neglects to consider the critical within-class scatter minimization. We present a Fuzzy support vector machine with pinball loss (FPin-SVM), which is a fuzzy extension of a reformulation of a recently proposed support vector machine with pinball loss (Pin-SVM) with several significant improvements, to improve the performance of FSVM. First, because we used the squared L2- norm of errors variables instead of the L1 norm, our FPin-SVM is a strongly convex minimization problem; second, to speed up the training procedure, solutions of the proposed FPin-SVM, as an unconstrained minimization problem, are obtained using the functional iterative and Newton methods. Third, it is proposed to solve the minimization problem directly in primal. Unlike FSVM and Pin-SVM, our FPin-SVM does not require a toolbox for optimization. We dig deeper into the features of FPin-SVM, such as noise insensitivity and within-class scatter minimization. We conducted experiments on synthetic and real-world datasets with various sounds to validate the usefulness of the suggested approach. Compared to the SVM, FSVM, and Pin-SVM, the presented approaches demonstrate equivalent or superior generalization performance in less training time.

Abstract
We show that Katětov and Rudin–Blass orders on summable tall ideals coincide. We prove that Katětov order on summable tall ideals is Galois–Tukey equivalent to

$(\omega ^\omega ,\le ^*)$

. It follows that Katětov order on summable tall ideals is upwards directed which answers a question of Minami and Sakai. In addition, we prove that

${l_\infty }$

is Borel bireducible to an equivalence relation induced by Katětov order on summable tall ideals.
Blagoustroistvo: Infrastructure, Determinism, (Re-)coloniality, and Social Engineering in Moscow, 1917–2022
Authors: Lähteenmäki Markus , Murawski Michał 
Published: April 2023

AbstractBlagoustroistvo is an archaic Russian word used today primarily to refer to urban public works. This article, a collaboration between an anthropologist and a historian, focuses on aesthetics, rhetorics, and concrete practices of blagoustroistvo in Moscow during two temporal junctures: the first decade following the October Revolution (ca. 1917–1930), and the decade of Sergey Sobyanin’s Moscow Mayoralty (2010–). Our juxtaposition reveals striking continuities and contrasts. Both in the 1920s and 2010s, we show, blagoustroistvo was characterized by a semiotically-intense presence in the city; associated with an emphasis on deterministic socio-psychological “engineering”; ideologically framed by a “vernacularized” form of Marxism-Leninism; and invested with a powerful role in reconfiguring society’s spatial hierarchies, political geometry, and class consciousness. In the former period, social transformation referred to the inversion of class hierarchies and a partly illusory reconfiguration of power between center and periphery. In the 2010s, however, blagoustroistvo became a project that sought a reversion to class categories and the re-colonial reconstitution of the center’s coercive domination of the fringes. Our analysis proffers blagoustroistvo—a high-modernist, deterministic “infrastructural ideology” that has endured into and flourished in the twenty-first century—as a uniquely illustrative concept for understanding the shifting ideologies of Soviet and post-Soviet infrastructural modernity and its winding but stubborn colonial logics. Moreover, our explication of blagoustroistvo’s trans-epochal meanderings brings comparative nuance to current global debates around the alleged “return” of “social engineering” to urban governance and design in the guise of artificial intelligence, big data, smart cities, and “surveillance capitalism.”

AbstractBackgroundThe 22q11.2 deletion (22q11Del) is among the strongest known genetic risk factors for psychosis. Stress, a known risk factor for psychosis in the general population, has seldom been studied in 22q11Del. We investigated how lifetime stressors related to symptomatic outcomes in patients with 22q11Del. We also explored this association in individuals with 22q11.2 duplications (22q11Dup), which may be potentially protective against psychosis.MethodOne hundred individuals (46 with 22q11Del, 30 with 22q11Dup, and 24 healthy controls; Mage = 17.30 years±10.15) were included. Logistic models were used to examine cross-sectional associations between lifetime acute and chronic stressors (severity and count) and the presence (score ⩾3) of positive, negative, and general symptoms, assessed via the Structured Interview for Psychosis-risk Syndromes (SIPS).ResultsThe 22q11Dup group reported the greatest number and severity of acute lifetime stressors, but did not differ from 22q11Del in chronic stressor count or severity. Lifetime chronic and acute stressors were uniquely associated with positive symptoms in 22q11Del (chronic count: odds ratio [OR] = 2.35, p = 0.02; chronic severity: OR = 1.88, p = 0.03; acute count: OR = 1.78, p = 0.03), but not with negative or general symptoms (ps > 0.05).ConclusionFindings suggest that stress may play a role in psychotic symptoms in 22q1Del, while the 22q11Dup CNV appears protective against psychotic symptoms despite higher rates of stressors. Interventions that mitigate effects of stressors in 22qDel may reduce the odds of psychosis in this group. Prospective longitudinal research is needed to replicate these findings.
Wisdom and suffering in Teresa of Cartagena
Authors: Drahos Kristen 
Published: April 2023

AbstractI argue that Teresa of Cartagena's Grove of the Infirm offers a recalibration of the wisdom emergent from suffering by moving from a cruciform spirituality to an intellectual ‘scientia,’ which benefits specific marginalized groups (prolonged sufferers) by establishing new paths of agency (through distinctive cooperative virtues) for those who suffer. I show that by disengaging suffering's spiritual meaning from the Franciscan focus on the cross, Teresa is able to amplify the relationship of virtue to wisdom while maintaining the validity of the painful experience endured. I argue that Teresa's focus on wisdom challenges the diminution of sufferers' experiences and elevates their spiritual wisdom as applicable to the church writ large. Teresa's work opens new spaces of agency for the most sidelined and secures the lasting significance of the wisdom of suffering.
The zīndag ruwān ceremony in historical perspective
Authors: Andrés-Toledo Miguel Ángel 
Published: April 2023

AbstractThe Pahlavi syntagm zīndag ruwān (NP zende/zinde ravān), literally “living soul / soul of the living”, designates a Zoroastrian funerary ceremony to be performed by priests on behalf of a person in his/her lifetime for the benefit of his/her own soul. It is particularly ordered by that person as a pre-emptive means to ensure that the funerary prayers will be recited, even if relatives are unable to do so, and to guarantee the protection of the god Sraoša in the passing away to the afterlife. In this contribution, I discuss the most relevant aspects of this Zoroastrian ceremony that can be extracted from the Pahlavi literature, and consider that its changes from older periods until modern times are due to diachronic, diatopic and socio-economic variables.

Abstract
For a

on vertex set

$\{1, \ldots, n\}$

an Erdős–Rényi random

$k$

-uniform hypergraph,

${\mathrm{coker}}(M(\mathcal{H}))$

,

${\mathrm{coker}}(M(\mathcal{H}))$

AbstractObjective:Emotional functioning is linked to HIV-associated neurocognitive impairment, yet research on this association among diverse people with HIV (PWH) is scant. We examined emotional health and its association with neurocognition in Hispanic and White PWH.Methods:Participants included 107 Hispanic (41% primarily Spanish-speakers; 80% Mexican heritage/origin) and 216 White PWH (Overall age: M = 53.62, SD = 12.19; 86% male; 63% AIDS; 92% on antiretroviral therapy). Emotional health was assessed via the National Institute of Health Toolbox (NIHTB)-Emotion Battery, which yields T-scores for three factor-based summary scores (negative affect, social satisfaction, and psychological well-being) and 13 individual component scales. Neurocognition was measured via demographically adjusted fluid cognition T-scores from the NIHTB-cognition battery.Results:27%–39% of the sample had problematic socioemotional summary scores. Hispanic PWH showed less loneliness, better social satisfaction, higher meaning and purpose, and better psychological well-being than Whites (ps <.05). Within Hispanics, Spanish-speakers showed better meaning and purpose, higher psychological well-being summary score, less anger hostility, but greater fear affect than English speakers. Only in Whites, worse negative affect (fear affect, perceived stress, and sadness) was associated with worse neurocognition (p <.05); and in both groups, worse social satisfaction (emotional support, friendship, and perceived rejection) was linked with worse neurocognition (p <.05).Conclusion:Adverse emotional health is common among PWH, with subgroups of Hispanics showing relative strengths in some domains. Aspects of emotional health differentially relate to neurocogntition among PWH and cross-culturally. Understanding these varying associations is an important step towards the development of culturally relevant interventions that promote neurocognitive health among Hispanic PWH.
