Transport characteristics and predictors of mortality among neonates referred to a tertiary care centre in North India: a prospective observational study
Authors: Singh Jasbir , Dalal Poonam , Gathwala Geeta , Rohilla Ravi
Published: July 2021

Objective

The paucity of specialised care in the peripheral areas of developing countries necessitates the referral of sick neonates to higher centres. Organised interhospital transport services provided by a skilled and well-equipped team can significantly improve the outcome. The present study evaluated the transport characteristics and predictors of mortality among neonates referred to a tertiary care centre in North India.

Design

Prospective observational study.

Settings

Tertiary care teaching hospital in North India.

Patients

1013 neonates referred from peripheral health units.

Main outcome measures

Mortality among referred neonates on admission to our centre.

Results

Of the 1013 enrolled neonates, 83% were transferred through national ambulance services, 13.7% through private hospital ambulances and 3.3% through personal vehicles. Major transfer indications were prematurity (35%), requirement for ventilation (32%), birth asphyxia (28%) and hyperbilirubinaemia (19%). Hypothermia (32.5%, 330 of 1013), shock (19%, 192 of 1013) and requirement for immediate cardiorespiratory support (ICRS) (10.4%, 106 of 1013) on arrival were the major complications observed during transfer. A total of 305 (30.1%, N=1013) deaths occurred. Of these, 52% (n=160) died within 24 hours of arrival. On multivariate logistic analysis, unsupervised pregnancy (<4 antenatal visits; p=0.037), antenatal complications (p<0.001), prematurity ≤30 weeks (p=0.005), shock (p=0.001), hypothermia (p<0.001), requirement for ICRS on arrival (p<0.001), birth asphyxia (p=0.004), travel time >2 hours (p=0.005) and absence of trained staff during transfer (p<0.001) were found to be significant predictors of mortality.

Conclusion

The present study depicts high mortality among infants referred to our centre. Adequate training of peripheral health personnel and availability of pre-referral stabilisation and dedicated interhospital transport teams for sick neonate transfers may prove valuable interventions for improved outcomes.
Subsidy programme for gestational diabetes mellitus screening and lifestyle management in rural areas of western China: a study protocol for a multicentre randomised controlled trial
Authors: Xu Tingting , Lai Xiaozhen , He Kun , Ma Liangkun , Fang Hai
Published: July 2021

Introduction

Gestational diabetes mellitus (GDM) has become an increasing health problem among pregnant women in western rural China. Insufficient compliance and motivation due to economic factors is one of the major contributors to the currently low GDM screening and management rate. A subsidy program offering GDM screening and lifestyle management might be an effective way to increase pregnant women’s awareness of GDM, and further improve maternal and neonatal health in western rural China. This study had two primary purposes: (1) to examine whether the subsidy program would increase the screening and management rates of GDM and reduce adverse complications for mothers and new-born babies and (2) to evaluate whether the subsidy program is cost-effective from a societal perspective.

Methods and analysis

This randomised controlled trial will include 3000 pregnant women (at 24–28 weeks of pregnancy) who will be followed up at six hospitals in the provinces of Yunnan, Sichuan and Shaanxi in China. Pregnant women without overt diabetes, with a singleton pregnancy, with telephone access and with written informed consent will be invited. The intervention group will receive subsidies and standard care, and the control group will only receive usual antenatal care. The randomisation sequence will be stratified by study sites with balanced blocks of six patients. Data will be collected using self-report questionnaires and hospital records. Data will be analysed according to the intention-to-treat principle. The primary outcomes are the maternal and neonatal complications. Secondary outcomes are the mother’s cognition scores, screening rate, number of re-examinations, weight gain during pregnancy, changes in diet and exercise, and quality of life. Group comparisons will be conducted using χ2test for categorical variables, and t-test or the Mann-Whitney-Wilcoxon test for continuous variables where applicable. Multiple logistic regression will also be performed for the primary outcomes.

Ethics and dissemination

This study was approved by the Ethics Review Committee of Peking University Health Science Center. Findings will be disseminated through publication in peer-reviewed journals, seminars and national and international conferences.

Internet-delivered Cognitive-Behavioral Therapy (iCBT) for Adults with Prolonged Grief Disorder (PGD): A Study Protocol for a Randomized Feasibility Trial
Authors: Tur Cintia , Campos Daniel , Herrero Rocio , Mor Sonia , López-Montoyo Alba , Castilla Diana , Quero Soledad
Published: July 2021

Introduction

Grief is an emotional reaction to the loss of a loved one with a natural recovery. Approximately 10% of people who lose a loved one develop prolonged grief disorder (PGD). Internet-based and computer-based interventions (ie, internet-delivered cognitive–behavioural therapy, iCBT) are a cost-effective alternative that makes it possible to reach more people with PGD. The main aim of this study is to assess the feasibility of a new iCBT—called GROw—for PGD. As a secondary objective, the potential effectiveness of GROw will be explored.

Methods and analysis

This study is a two-arm feasibility randomised trial. A total of 48 adults with PGD who meet the eligibility criteria will be randomised to the experimental group (iCBT: GROw) or the active control group (face-to-face CBT treatment). The treatment is organised sequentially in eight modules in the iCBT format and 8–10 sessions in the face-to-face format, and both formats have the same therapeutic components. There will be five assessment points with qualitative and quantitative evaluations: screening, baseline, after the intervention, 3-month follow-up and 12-month follow-up. Consistent with the objectives, the measures are related to the feasibility outcomes for the main aim of the study (participant adherence, expectations and satisfaction with the treatment, preferences, alliance and utility) and psychological and mental health outcomes for secondary analyses (symptoms of grief, symptoms of depression, symptoms of anxiety, affectivity, quality of life, work and social adaptation, post-traumatic growth, purpose in life, mindfulness and compassion).

Ethics and dissemination

The Ethics Committee of the Universitat Jaume I (Castellón, Spain) granted approval for the study (CD/002/2019). Dissemination will include publications and presentations at national and international conferences.

Prevalence of abdominal obesity and its association with cardiovascular risk among the adult population in Burkina Faso: findings from a nationwide cross-sectional study
Authors: Cisse Kadari , Samadoulougou Sékou , Ouedraogo Mady , Kouanda Seni , Kirakoya-Samadoulougou Fati
Published: July 2021

Objective

The objective of this study is to determine the prevalence of abdominal obesity, its predictors and its association with cardiovascular risk among adults in Burkina Faso.

Design

We performed a secondary analysis of data from a national cross-sectional study, using WHO STEPwise approach.

Setting

The study was conducted in Burkina Faso, in all the 13 regions of the country.

Participants

Our study involved 4308 adults of both sexes, aged between 25 and 64 years.

Primary and secondary outcomes

Our primary outcome was abdominal obesity, which was defined using a cut-off point of waist circumference (WC) of ≥94 cm for men and ≥80 cm for women. The secondary outcome was very high WC (≥102 cm for men and ≥88 cm for women) (for whom weight management is required).

Results

The mean age of participants was 38.5±11.1 years. The age-standardised prevalence of abdominal obesity was 22.5% (95% CI 21.3% to 23.7%). This prevalence was 35.9% (95% CI 33.9% to 37.9%) among women and 5.2% (95% CI 4.3% to 6.2%) among men. In urban areas, the age-standardised prevalence of abdominal obesity was 42.8% (95% CI 39.9% to 45.7%) and 17.0% (95% CI 15.7% to 18.2%) in rural areas. The age-standardised prevalence of very high WC was 10.2% (95% CI 9.3% to 11.1%). The main predictors of abdominal obesity were being female, increased age, married status, high level of education and living in urban areas. Abdominal obesity was also significantly associated with high blood pressure (adjusted prevalence ratio (aPR): 1.30; 95% CI 1.14 to 1.47) and hypercholesterolaemia (aPR: 1.52; 95% CI 1.18 to 1.94). According to the combination matrix between body mass index and WC, 14.6% of the adult population in Burkina Faso had an increased cardiometabolic risk.

Conclusion

Our study showed a high prevalence of abdominal obesity and a high proportion of adults who require weight management strategies to prevent cardiometabolic complications. Strategies to reduce the burden of abdominal obesity and very high WC should be considered by Burkina Faso’s policy-makers.
Validation of the German Life-Space Assessment (LSA-D): cross-sectional validation study in urban and rural community-dwelling older adults
Authors: Mümken Sandra Angelika , Gellert Paul , Stollwerck Malte , O'Sullivan Julie Lorraine , Kiselev Joern
Published: July 2021

Objectives

To develop a German version of the original University of Alabama at Birmingham Study of Aging Life-Space Assessment (LSA-D) for measurement of community mobility in older adults within the past 4 weeks and to evaluate its construct validity for urban and rural populations of older adults.

Design

Cross-sectional validation study.

Setting

Two study centres in urban and rural German outpatient hospital settings.

Participants

In total, N=83 community-dwelling older adults were recruited (n=40 from urban and n=43 from rural areas; mean age was 78.5 years (SD=5.4); 49.4% men).

Primary and secondary outcome measures

The final version of the translated LSA-D was related to limitations in activities and instrumental activities of daily living (ADL/iADL) as primary outcome measure (primary hypothesis); and with sociodemographic factors, functional mobility, self-rated health, balance confidence and history of falls as secondary outcome measures to obtain construct validity. Further descriptive measurements of health included hand grip strength, screening of cognitive function, comorbidities and use of transportation. To assess construct validity, correlations between LSA-D and the primary and secondary outcome measures were examined for the total sample, and urban and rural subsamples using bivariate regression and multiple adjusted regression models. Descriptive analyses of LSA-D included different scoring methods for each region. All parameters were estimated using non-parametric bootstrapping procedure.

Results

In the multiple adjusted model for the total sample, number of ADL/iADL limitations (β=−0.26; 95% CI=−0.42 to −0.08), Timed Up and Go Test (β=−0.37; 95% CI=−0.68 to −0.14), shared living arrangements (β=0.22; 95% CI=0.01 to 0.44) and history of falls in the past 6 months (β=−0.22; 95% CI=−0.41 to −0.05) showed significant associations with the LSA-D composite score, while living in urban area (β=−0.19; 95% CI=−0.42 to 0.03) and male gender (β=0.15; 95% CI=−0.04 to 0.35) were not significant.

Conclusion

The LSA-D is a valid tool for measuring life-space mobility in German community-dwelling older adults within the past 4 weeks in ambulant urban and rural settings.

Sampling with probability proportional to prediction (3P sampling) using covariates derived from spherical images
Authors: Hsu Yung-Han , Kershaw John A. , Ducey Mark J. , Yang Ting-Ru , Wang Haozhou
Published: July 2021

Using a two-phase sampling approach with systematic selection of large samples of covariates followed by a sampling with probability proportional to prediction (3P sampling) process to subsample field measures of the parameters of interest can be an efficient design to sample larger forest areas. To assist in obtaining predictions for each sample plot consistently and rapidly, we propose using a 360° spherical camera. In this study, three covariates derived from spherical images were evaluated: (i) basal area (P[BA]); (ii) sum of squared heights per hectare (P[SHT]); and (iii) stem fraction (P[SF]). These covariates were used to estimate volume. Sample simulations showed no biases in volume estimates for any of the three covariates. Overall, P[SF] had the lowest standard error percentages across different simulated sample sizes (10% for five subsamples to 2.5% for 50 subsamples), even though it had the lowest correlations with field volume (correlation = 0.30–0.31). This may be a result of the relatively consistent stand conditions within the study site. Based on our results, standard errors of 5% were obtainable with measurement fractions of about 25% of the number of image-based predictions when using P[SF] or P[BA] and 75% when using P[SHT].
Beyond the relaxation time approximation
Authors: Wilk Grzegorz , Włodarczyk Zbigniew
Published: July 2021

The relaxation time approximation (RTA) is a well known method of describing the time evolution of a statistical ensemble by linking distributions of the variables of interest at different stages of their temporal evolution. We show that if all the distributions occurring in the RTA have the same functional form of a quasi-power Tsallis distribution the time evolution of which depends on the time evolution of its control parameter, nonextensivity q(t), then it is more convenient to consider only the time evolution of this control parameter.
Flow of online misinformation during the peak of the COVID-19 pandemic in Italy

Published: July 2021

The COVID-19 pandemic has impacted on every human activity and, because of the urgency of finding the proper responses to such an unprecedented emergency, it generated a diffused societal debate. The online version of this discussion was not exempted by the presence of misinformation campaigns, but, differently from what already witnessed in other debates, the COVID-19 -intentional or not- flow of false information put at severe risk the public health, possibly reducing the efficacy of government countermeasures. In this manuscript, we study theeffectiveimpact of misinformation in the Italian societal debate on Twitter during the pandemic, focusing on the various discursive communities. In order to extract such communities, we start by focusing on verified users, i.e., accounts whose identity is officially certified by Twitter. We start by considering each couple of verified users and count how many unverified ones interacted with both of them via tweets or retweets: if this number is statically significant, i.e. so great that it cannot be explained only by their activity on the online social network, we can consider the two verified accounts as similar and put a link connecting them in a monopartite network of verified users. The discursive communities can then be found by running a community detection algorithm on this network.

We observe that, despite being a mostly scientific subject, the COVID-19 discussion shows a clear division in what results to be different political groups. We filter the network of retweets from random noise and check the presence of messages displaying URLs. By using the well known browser extension NewsGuard, we assess the trustworthiness of the most recurrent news sites, among those tweeted by the political groups. The impact of low reputable posts reaches the 22.1% in the right and center-right wing community and its contribution is even stronger in absolute numbers, due to the activity of this group: 96% of all non reputable URLs shared by political groups come from this community.

Application of Traditional Chinese Medicine and Systems Pharmacology in Drug Prevention and Treatment against COVID-19
Authors: Zhou Wei , Chen Ziyi , Sun Xizhuo , Zhong Nanshan , Liu Zhigang
Published: July 2021

A novel coronavirus named SARS-CoV-2 is causing the severe acute pneumonia (COVID-19) and rapid spread nationally and internationally, resulting in a major global health emergency. Chinese governments and scientists have implemented a series of rigorous measures and scientific research to prevent and control the SARS-CoV-2 infection. However, there is still no specific antiviral drug or vaccine against SARS-CoV-2. It has been proven that traditional Chinese medicine (TCM) exerts an important role in the prevention and treatment of the COVID-19 caused by SARS-CoV-2 during the outbreak. Although the therapeutic effects of these TCM formulas are attractive, the molecular mechanism of action has not been fully elucidated. An emerging strategy of systems pharmacology has been proposed to be a promising method to interpret drug action in complex biological systems and quickly screen out the bioactive compounds from TCM to treat treatment of COVID-19 caused by SARS-CoV-2. Therefore, in this study, the epidemiology, TCM therapy, and the systems pharmacology-based method for TCM are reviewed for COVID-19 to provide a perspective for the prevention and treatment of SARS-CoV-2 infection. Further efforts should be made to reduce disease burden and improve the ability to design antiviral drugs and vaccines, which will benefit the health care system, economic development and even social stability.
Two-Stage Heuristic Algorithm Proposal for Urban E-Commerce Deliveries
Authors: Karaoğlu Mehmet , Kara Gökhan
Published: July 2021

In today’s intensive competition conditions, it is an inevitable necessity for the companies operating in the e-commerce sector to manage their physical distribution processes efficiently and effectively. The most important step in e-commerce logistics processes is the last step delivery operations in the city. In order for these operations to be carried out quickly and efficiently, delivery vehicles and personnel must be optimally led. These problems, referred to as vehicle routing problem (VRP) in the literature, include determining the least cost routes that vehicles will cover to meet customer needs. In this study, the urban delivery problems of the enterprises operating in the online retail sector are examined. In line with these problems, VRP for urban e-commerce deliveries has been modified; open, multi-depot, distribution aggregation, time-window VRP is discussed. A mathematical model for the modified VRP has been developed and a new heuristic algorithm consisting of two stages has been developed for large-scale problems. The developed algorithm was tested on three different cases. The results are compared with the solution of the nearest neighbor method and the performance of the proposed algorithm is presented.

A secure image cryptosystem via multiple chaotic maps
Authors: Wazi Mayada T. , Ali Dalia S. , Al-Saidi Nadia M. G. , Alawn Nawras A.
Published: July 2021

This work focused on introducing a new two-dimensional (2D) chaotic system. It is combined of some existing maps, the logistic, iterative chaotic map with infinite collapse, and Henon maps; we called it 2D-LCHM. The assessment of the actual performance of 2D-LCHM presents its sensitivity to a tiny change in the initial condition. Besides, its dynamics behavior is very complicated. It also has hyperchaotic properties and good ergodicity. The proposed system is occupied with designing a new image encryption system. Changing the image pixels’ locations is the primary step in the encryption process. The original image is splitting into four blocks to create four different keys based on 2D-LCHM; this reduces the computation time and increases the complexity. To obtain the encryption image, we have to repeat the partitioning process several times for each block. The encryption image’s efficiency is shown through some performance analysis such as; image histogram, the number of pixels changes rate (NPCR), the unified average changing intensity (UACI), pixels correlation, and entropy. The proposed system is compared with some efficient encryption algorithms in terms of chaocity attributes and image performance; the analysis result showed consistent improvement.
Impact of high-salt versus low-salt intake on the response of sympathetic baroreflex sensitivity to orthostasis in women with a history of normal pregnancy
Authors: Takeda Ryosuke , Stickford Abigail S.L. , Best Stuart A. , Yoo Jeung-Ki , Hissen Sarah L. , Liu Yu-Lun , Fu Qi
Published: July 2021

Previous studies have demonstrated that sympathetic baroreflex sensitivity (BRS) increases during orthostatic stress in humans. We recently showed that dietary salt intake affects sympathetic neural control in healthy premenopausal women. This study aimed to determine whether salt loading versus salt reduction would impact sympathetic BRS during orthostasis in premenopausal women with a history of normal pregnancy. Nine healthy women [42 ± 3 (SD) yr] were given a standardized isocaloric high-salt (250 mEq sodium/day) or low-salt (50 mEq sodium/day) diet for 1 wk each (∼2 mo apart with the order randomized), whereas water intake was ad libitum. Laboratory testing was performed following each high- and low-salt period in the midluteal phase of the menstrual cycle. Hemodynamics and muscle sympathetic nerve activity (MSNA) were measured at baseline (supine; 2 min) and during a graded head-up tilt (30° for 5 min and 60° for 20 min). Sympathetic BRS was assessed during baseline and head-up tilt. Hemodynamics were not different between salt conditions during baseline or tilt. Both supine and upright MSNA indices were lower in high salt than low salt (all P < 0.05), however, there was no interaction effect ( P = 0.507–0.996). On moving from supine to upright, sympathetic BRS remained unchanged in high salt but increased in low salt ( P = 0.028 for interaction). Thus, salt loading diminishes the responsiveness of sympathetic BRS during orthostasis compared with salt reduction in healthy premenopausal women with prior normal pregnancy. Whether this is one underlying mechanism for salt-induced development of hypertension during ambulation remains to be determined.
The Effects of Online Information on E-Book Pricing Strategies: A Text Analytics Approach
Authors: Li Kang , Zhang Lunchuan , Wang Dianwei , Pan Dinglu
Published: July 2021

Nowadays, electronic book vendors are increasingly proactive in trying to strategically capitalize on online big data generated by consumers. It will bring great profit for vendors if they can make the most of online reviews to figure out the impact of online data on the selling prices of e-books. In this paper, we complement an emerging body of research to explore how e-book prices could be affected by online information via analyzing the sheer volume of online data from e-book websites, namely, we first employ a domain ontology-based method to select the most discriminative features that may affect e-book prices. Then, the topic modeling method latent Dirichlet allocation and aspect-oriented sentiment analysis methods are applied as a supplement. Using the multiple regression method, we identify the key features that may have effects on the prices of e-books and give the related regression equation. In our results, some factors including paper book prices, paper book pages corresponding to the e-book, and e-book content have significant effects on the price of e-books. The managerial implication is that e-book firms can obtain a reference price for an e-book and may dynamically adjust the price to increase e-book sales according to our data analysis results.

Authors: Zhou Bin , Chen Min
Published: July 2021

To explore the impact of different image registration algorithms on the diagnosis of visual path damage in patients with primary open angle glaucoma (POAG), 60 cases of suspected POAG patients were selected as the research objects. Shape-preserving scale invariant feature transform (SP-SIFT) algorithm, scale invariant feature transform (SIFT) algorithm, and Kanade-Lucas-Tomasi (KLT) algorithm were compared and applied to MRI images of 60 POAG patients. It was found that the SP-SIFT algorithm converged after 33 iterations, which had a higher registration speed than the SIFT algorithm and the KLT algorithm. The mean errors of the SP-SIFT algorithm in the rotation angle, X-direction translation, and Y-direction translation were 2.11%, 4.56%, and 4.31%, respectively. Those of the SIFT algorithm were 5.55%, 9.98%, and 7.01%, respectively. Those of the KLT algorithm were 7.45%, 11.31%, and 8.56%, respectively, and the difference among algorithms was significant (

P
<
0.05

). The diagnostic sensitivity and accuracy of the SP-SIFT algorithm for POAG were 96.15% and 94.34%, respectively. Those of the SIFT algorithm were 94.68% and 90.74%, respectively. Those of the KLT algorithm were 94.21% and 90.57%, respectively, and the three algorithms had significant differences (

P
<
0.05

). The results of MRI images based on the SP-SIFT algorithm showed that the average thickness of the cortex of the patient’s left talar sulcus, right talar sulcus, left middle temporal gyrus, and left fusiform gyrus were 2.49 ± 0.15 mm, 2.62 ± 0.13 mm, 3.00 ± 0.10 mm, and 2.99 ± 0.17 mm, respectively. Those of the SIFT algorithm were 2.51 ± 0.17 mm, 2.69 ± 0.12 mm, 3.11 ± 0.13 mm, and 3.09 ± 0.14 mm, respectively. Those of the KLT algorithm were 2.35 ± 0.12 mm, 2.52 ± 0.16 mm, 2.77 ± 0.11 mm, and 2.87 ± 0.17 mm, respectively, and the three algorithms had significant differences (

P

). In summary, the SP-SIFT algorithm was ideal for POAG visual pathway diagnosis and was of great adoption potential in clinical diagnosis.
Research on the Innovation Path of Business Models Based on the Market Orientation
Authors: Ma Yongmei , Wei Huafei , Hu Chuanshuang , Jin Chenglin
Published: July 2021

Current research considers business model innovation as a series of responses to technological change and market environment change. However, in practice, it is often business model innovation that leads to market innovation and subversion and then promotes a new round of iterative product renewal. This is because business model innovation is a value creation activity based on market demand, rather than a technology‐oriented innovation behavior. Moreover, since the degree of demand manifestation varies, the degree of its influence on value creation and thus the driving mechanism for business model innovation vary significantly, and the duality of market‐oriented theory is introduced to explore how firms go about achieving business model innovation based on different demand characteristics and how the results of firms’ integration of market information work. Through regression analysis of 230 sample enterprises, the results show that both responsiveness and proactive market orientation have a significant positive impact on business model innovation. In contrast, market information integration has a positive regulatory effect on the two groups of relationships.
Recurrent Prostatic Stromal Tumor of Uncertain Malignant Potential Combined with Concurrent Prostatic Adenocarcinoma: An Unusual Case
Authors: Zhang Zhen , Liang Chaozhao
Published: July 2021

Prostatic stromal tumor of uncertain malignant potential (STUMP), characterized by an atypical, unique stromal proliferation of the prostate, is often difficult to be differentiated from other nonepithelial neoplastic lesions. We present a unique case of recurrent STUMP after transurethral resection of the prostate (TURP) with concurrent prostatic adenocarcinoma. Patients diagnosed with prostatic STUMP should be followed up closely, for it may recur and invade adjacent organs after TURP shortly. Concurrent prostatic adenocarcinoma can be found in STUMP patients, and there may be some potential mechanisms which promote the simultaneous occurrence of the 2 tumors.

Published: July 2021

Maximizing capacity of distributed generations (DGs) embed into distribution network is a solution to attract investment for DGs installation on the distribution system. This paper introduces a approach of optimizing location and capacity of DGs for maximizing DGs capacity and minimizing the system’s power loss based on cuckoo search algorithm (CSA). The proposed problem and method are simulated on two test systems including the 33-node and 69-node networks. The numerical results have demonstrated that the proposed method not only reduces power losses but also maximizes the power of DGs embed into the distribution network. The results also introduce that the proposed CSA method is better performance that some previous methods in terms of power loss and DGs capacity. The results obtained in many independent runs for two test systems indicate that CSA in one of the reliable methods for the DGs placement problems.
El sexo y la ciudad. Homosociabilidad y disidencia en Berlin Alexanderplatz de Alfred Döblin
Authors: Rubino Atilio Raúl
Published: July 2021

La novela de Berlin Alexanderplatz (1929) de Alfred Döblin surge en una época y un espacio de enorme ebullición política y también de militancia sexo-disidente, el Berlín de la República de Weimar. Compuesta como un montaje de las voces de la gran ciudad, la novela deja ingresar muchas de las tensiones, discusiones y militancias de la época en torno a la disidencia sexual. Este artículo, en consecuencia, realiza un recorrido por esas representaciones sexo-disidentes en Berlin Alexanderplatz para pensarlas en tensión con la producción y reproducción de la masculinidad heterosexual. En contraste con esta efervescencia sexual del Berlín de los años veinte, me interesa también pensar la producción de las cisheteromasculinidades pensada a partir del concepto de homosociabildiad, fundamentalmente en de la relación entre los personajes de Franz y Reinhold. De esta forma, se puede vincular también este punto con la violencia y agresividad contra la mujer, muy marcada en la novela de Döblin, y, principalmente, con el intercambio de mujeres entre Franz y Reinhold.
Historia de una enfermedad: Der Alpdruck de Hans Fallada y la identidad alemana frente a la herencia nacionalsocialista
Authors: Andrade Ricardo
Published: July 2021

El presente artículo explora una novela olvidada en la producción literaria de Hans Fallada: Der Alpdruck. Esta novela, testimonio del sufrimiento y la esperanza de la sociedad alemana en los primeros años posteriores a la Segunda Guerra Mundial, indaga en la herencia del nacionalsocialismo en la vida individual y colectiva. Conceptos centrales como el arraigo, la identidad y el lenguaje se transforman en elementos centrales para comprender las consecuencias del terror político y el dolor de una existencia desprovista de horizontes afectivos y reflexivos. El artículo se detiene en dichos conceptos tomando algunos capítulos de la novela para evidenciar la permanencia del nacionalsocialismo en diversos aspectos de los sujetos y el intento de lidiar con dicha herencia para pensar Alemania.
Textos didatizados e não didatizados de alemão como língua adicional: uma análise quantitativa e qualitativa para o projeto Zeitgeist

Essa proposta é justificada pelo interesse em desenvolver uma base empírica que auxilie a seleção de textos para um projeto de criação de um material didático destinado ao ensino de alemão em contexto universitário no Brasil. Para o tratamento dos textos utilizamos os programas WordSmith Tools (2016) e QuAX-DaF (2019). Tais ferramentas apresentam dados de frequência de ocorrência nos textos investigados, além de estabelecer uma relação com um corpus autêntico de língua alemã (Leipzig Corpora Collection). Os resultados indicam que a investigação da frequência de ocorrência pode estabelecer uma base quantitativa e qualitativa para a escolha textual de acordo com a progressão lexical e gramatical desejada, podendo ser um critério para a inclusão ou de exclusão de textos para o ensino de línguas.
O fundacionalismo de Thomas Reid
Authors: Freitas Vinícius França
Published: July 2021

O objetivo do artigo é discutir em que medida Thomas Reid está comprometido com uma teoria fundacionalista da justificação epistêmica. Para tal, apresentam-se duas discussões. Em primeiro lugar, argumenta-se que apesar de ser um fundacionalista em geral, Reid não o é em relação a todos os âmbitos do conhecimento - como é o caso da política. Para compreender essa hipótese, distingue-se sua concepção axiomática de ciência de sua visão fundacionalista da estrutura do conhecimento. Em segundo lugar, apresentam-se objeções às interpretações que pretendem que Reid é um antifundacionalista, um coerentista, ou um fundarentista.

Semelhança, imitação afetiva e vida comum
Authors: Jesus Paula Bettani Mendes de
Published: July 2021

Reconstruindo alguns pontos da dedução operada por Espinosa na Parte III da Ética, este artigo propõe refletir sobre a lógica afetiva e sobre duas importantes noções no contexto das relações interindividuais: de um lado, a concepção de semelhança, mais precisamente, a noção de “algo semelhante a nós” e, de outro lado, a imitação dos afetos. Nossa proposta é ponderar sobre como, se e em que medida a conjunção desses dois elementos – reconhecimento da semelhança com o outro e mimese afetiva – atua ou interfere no arranjo afetivo inter-humano e, assim, na possibilidade de efetivação e sustentação de uma vida comum.
Culture as a Fluid Interlocutor: Perspectives on Water Diplomacy from South Asia
Authors: Bisht Medha , Ahmed Syed Jamil
Published: July 2021

This article articulates culture in the terrain of water diplomacy. Situating the ‘local’ turn in transboundary water discourse, we argue that dialogue should be made a distinct precursor to formal processes of negotiations in South Asia. Notions of ‘culture’ and ‘community’ are revisited to examine shared ground between social/cultural anthropology and diplomacy studies. The central proposition here is that the idea of transition from political community to water community highlights the potential of culture as a fluid interlocutor. Culture, we argue, can be a non-verbal communicator not only for constituting water communities but also for giving meaning to water flowing in transboundary rivers in holistic terms. Given that these holistic ways of knowing and understanding water are not alien to ‘South Asian perspectives’, culture is offered as a transformative dialogic technique which can help rewrite the notion of community in complex geopolitical settings such as that of South Asia.
Al-Maʿarrī’s Anxious Menagerie: The Epistle of the Horse and the Mule
Authors: Blankinship Kevin
Published: July 2021

Around the year 411/1021, blind author and controversial freethinker Abū l-ʿAlāʾ al-Maʿarrī (449/1057) wrote Risālat al-ṣāhil wa-l-shāḥij (The Epistle of the Horse and the Mule), a meandering prose work populated by animal characters who talk about Syrian society on the eve of the crusades. The story exudes a brand of fictionality, namely creative literary exaggeration designed to call forth mental pictures, that sets it apart from other animal texts due to the overwhelming ambiguity it creates. The animal characters suffer existential anxiety when, for instance, they realize that concepts like genus (jins) and species (nawʿ) turn out to be fuzzier than they thought, thereby calling into question whether any species—be it biological or linguistic—is a stable class. Animal ontology gets further confused by just-so stories about hybrids and crossbreeds, and by terms for philosophical contingency that question whether talking animals even exist—this is not just a story that did not happen, but a story that cannot happen except in the imagination. On the other hand, those same philosophical terms may yet affirm that speaking animals could exist, and that they have value in themselves, by hinting at their place in a cosmic order that radiates the goodness of its Source.

A new species of Pronura (Neanuridae: Paleonurini) from the Luquillo Mountains, Puerto Rico with a key to American poorly tuberculated Paleonurini
Authors: OSPINA-SÁNCHEZ CLAUDIA M. , PALACIOS-VARGAS JOSÉ G. , GONZÁLEZ GRIZELLE
Published: July 2021

A new species of Pronura from the Luquillo Experimental Forest on Northeastern Puerto Rico is described and illustrated. Pronura yunquensis sp. nov. differs from other Neotropical Pronura in the absence of eyes and can be separated from other species of the genus by the presence of a head tubercle (De), the displacement of Di1 in Abd IV and the fused tubercles De+DL in Abd V. A key for identification to American species of Paramanura, Pronura and Paleonura is included.
New records of deep-sea ascidians (Tunicata, Ascidiacea) from the New Caledonia region
Authors: MONNIOT FRANCOISE
Published: July 2021

The deep marine bottoms around New Caledonia have been explored for forty years. The Kanacono (2016) and Kanadeep (2019) campaigns organized jointly by the Muséum national d’Histoire naturelle (MNHN) and the Institut de Recherche pour le Développement (IRD) are the complement of this investigation. They are a part of the program “La Planète Revisitée” in New Caledonia. Among the deep sea benthos twenty two ascidian species were collected and three represent new species showing the characteristic adaptations to an abyssal life. The high diversity of the tropical deep sea benthos is enhanced by these new results. No relations are found between littoral ascidians and forms living in the bathyal or abyssal areas.
Robust atmospheric river response to global warming in idealized and comprehensive climate models
Authors: Zhang Pengfei , Chen Gang , Ma Weiming , Ming Yi , Wu Zheng
Published: July 2021

Atmospheric rivers (ARs), narrow intense moisture transport, account for much of the poleward moisture transport in midlatitudes. While studies have characterized AR features and the associated hydrological impacts in a warming climate in observations and comprehensive climate models, the fundamental dynamics for changes in AR statistics (e.g., frequency, length, width) are not well understood. Here we investigate AR response to global warming with a combination of idealized and comprehensive climate models. To that end, we developed an idealized atmospheric GCM with Earth-like global circulation and hydrological cycle, in which water vapor and clouds are modeled as passive tracers with simple cloud microphysics and precipitation processes. Despite the simplicity of model physics, it reasonably reproduces observed dynamical structures for individual ARs, statistical characteristics of ARs, and spatial distributions of AR climatology. Under climate warming, the idealized model produces robust AR changes similar to CESM large ensemble simulations under RCP8.5, including AR size expansion, intensified landfall moisture transport, and an increased AR frequency, corroborating previously reported AR changes under global warming by climate models. In addition, the latitude of AR frequency maximum shifts poleward with climate warming. Further analysis suggests the thermodynamic effect (i.e., an increase in water vapor) dominates the AR statistics and frequency changes while both the dynamic and thermodynamic effects contribute to the AR poleward shift. These results demonstrate that AR changes in a warming climate can be understood as passive water vapor and cloud tracers regulated by large-scale atmospheric circulation, whereas convection and latent heat feedback are of secondary importance.
Progressive Pulse Compression: A Novel Technique for Blind Range Recovery for Solid-State Radars
Authors: Salazar Aquino Cesar M. , Cheong Boonleng , Palmer Robert D.
Published: July 2021

In this paper, a novel technique is proposed to mitigate the so-called blind range on radars that use pulse compression. It is well known that the blind range is caused by the strong leak-through into the receiver during the transmission cycle. The proposed technique is called progressive pulse compression (PPC) and is based on partial decoding. PPC uses a portion of the uncontaminated received signal in conjunction with pulse compression to estimate the echoes from the incomplete signal. The technique does not require the use of a fill pulse or any hardware modifications. PPC can be divided into three steps. The fist step is to discard all the received signals during the transmit cycle and apply a smooth taper for continuous transition from zero to one. The second step is to perform the pulse compression using matched filter. The combination of these two steps is equivalent to performing pulse compression using a progressively changing template to partially extract the uncontaminated received signal for compression. The third step is to compensate for the progressively changing template so that proper reflectivity values can be recovered. This technique has been tested on the PX-1000 and will be implemented on PX-10k in the near future. These two radars are designed and operated by the Advanced Radar Research Center at the University of Oklahoma and are both X-band software-defined solid-state systems. The results presented in this paper are collected using the PX-1000 radar.
Police Brutality and Mexican American Families in Texas, 1945–1980
Authors: Campney Brent M. S.
Published: July 2021

Scholarly literature on racist violence has typically focused on the experiences of young males who suffer a disproportionate share of the police violence directed at their communities. This study widens our view of the effects of racist violence by examining the experiences of the family members of these men, and particularly the wives, children, parents, and siblings. The article shows that family members often witnessed the abuse of their loved ones, endured feelings of helplessness in the face of these acts of violence, confronted threats (or worse) from these officers at the time or subsequently, and experienced firsthand the injustice of the justice system. The article builds on a recent scholarship on racist violence—primarily lynchings—that focuses on the effects of this violence on the families and communities of the victims.

Published: July 2021

Objectives:

There is limited evidence on the impact of parental mental health problems on offspring’s educational outcomes. We investigated the impact of maternal anxiety and depressive symptoms, as well as paternal emotional problems on the educational outcomes of their adolescent and young adult offspring.

Methods:

We used data from a longitudinal birth cohort recruited between 1989 and 1991 in Australia (the Raine Study). The Depression, Anxiety and Stress Scale was used to assess maternal depressive and anxiety symptoms, and a self-reported question was used to measure paternal mental health problems. Both were assessed when the offspring was aged 10 years. Outcomes included offspring’s self-reported education attainment—not completing year 10 at age 17, not attending tertiary education at ages 17 and 22 and primary caregiver’s reports of offspring’s academic performance at age 17.

Results:

A total of 1033, 1307 and 1364 parent–offspring pairs were included in the final analysis exploring the association between parental mental health problems and offspring’s academic performance at school, completing year 10 and attending tertiary education, respectively. After adjusting for potential confounders, the offspring of mothers with anxiety symptoms were 3.42 times more likely than the offspring of mothers without anxiety symptoms to have poor or below-average academic performance (odds ratio = 3.42; 95% confidence interval = [1.31, 8.92]) and more than 2 times more likely to not attend tertiary education (odds ratio = 2.55; 95% confidence interval = [1.10, 5.5.88]) and not to have completed year 10 (odds ratio = 2.13; 95% confidence interval = [1.04, 4.33]). We found no significant associations between maternal depressive symptoms or paternal emotional problems and offspring educational attainment.

Conclusion:

Maternal anxiety symptoms, but not depression and paternal emotional problems, are associated with poor educational attainment and achievement in adolescent offspring. The findings highlight that efforts to improve the outcomes of offspring of mothers with anxiety could focus on educational attainment.
