Queue Length Estimation Based on Probe Vehicle Data at Signalized Intersections
Authors: Luo Huidan , Deng Mingjun , Chen Jia
Published: July 2023

Queue length is one of the important indexes to evaluate the operation efficiency of signalized intersection and also the key parameter of intersection signal control optimization. Traditional queue length estimation models are mostly based on fixed detection equipment, and the models assumptions are too harsh; there are certain limitations. Based on the probe vehicle data, this paper establishes a model of queue length estimation for signalized intersection based on shockwave theory. First, based on the speed and location data of the probe vehicle, the vehicle density is calculated to estimate the intersection stop line. A real-time calculation method of vehicle arrival rate is proposed to improve the applicability of the model. Then, based on the shockwave theory, the meeting time of the queue forming wave and the queue discharging wave are calculated after the green light is on. Finally, the queue length is summed in sections, including the distance between the last queued probe vehicle and the stop line during the red light period, the length of the subsequent vehicles arriving during the residual red light time, and the newly increased queue length within the queue discharging time. This paper uses the VISSIM software to simulate the actual intersection. The simulation results show that when the penetration of probe vehicle is 50%, 25%, and 10%, their corresponding mean absolute relative error are 11.27%, 27.77%, and 39.12%, respectively. It can be seen that with the increase of penetration, the error gradually decreases. The average absolute relative error is within the acceptable range. After analyzing the existing similar methods, although the accuracy of the method proposed in this paper does not reach the highest level, it has the advantages of simple operation, less computation, and good real-time computation. Relevant research results can provide support for traffic control at signalized intersections.

Authors: Shamsi Farimah , Karimi Mehran , Nafei Zahra , Akbarian Elahe
Published: July 2023

Introduction. COVID-19 prognostic risk factors, therapeutic protocols, and clinical outcomes in pediatric cases are still under investigation. Materials and Methods. This historical cohort study evaluated the survival time of hospitalized children (1 month–18 years old) with COVID-19 admitted from March 2020 to August 2021 to an educational hospital in Yazd, Iran. The follow-up of patients was performed at least one month after discharge. Results. From 183 hospitalized cases, 24 children were deceased. The median age of patients was 5.41, and 54.2% were male. The survival rate after one-month follow-up was 0.88, and the most significant predictors associated with survival time were the male sex, positive history of hospitalization, lymphopenia, hypoxia, and length of stay more than two weeks using Bayesian Cox regression analysis. Conclusion. Accurate estimation of the impact of predictors on poor outcomes may help healthcare providers use therapeutic protocols based on risk factors and healthcare requirements of each patient to improve their survival.
Molecular Characterization and Immunological Approaches Associated with Yellow Grub Trematode (Clinostomid) Infecting Nile Tilapia
Authors: Mahdy Olfat A. , Abdelsalam Mohamed , Salem Mai A.
Published: July 2023

Yellow grub disease is caused by clinostomid metacercariae (CM) infecting freshwater fish and has a potential impact on human health by causing Halzoun disease. This study aimed to combine both molecular and immunological approaches to characterize CM naturally infecting Nile tilapia. Two hundred and fifty Nile tilapia, Oreochromis niloticus, were collected from Giza Governorate and screened for the presence of CM. Samples were collected from buccal cavities and blood of 20 highly infected fish (≥10 cysts/fish) under aseptic conditions. Partial sequencing of the ITS rRNA region was performed to identify and distinguish the causative agents from closely related species. The cellular immune response between infected and noninfected O. niloticus was investigated by quantitative real-time-PCR targeting tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Results showed significant increases in the levels of both TNF-α and IL-1β (

Source Localization Using RSS Measurements with Sensor Position Uncertainty
Authors: Wang Qi , Li Xianqing
Published: July 2023

Received signal strength- (RSS-) based localization has attracted considerable attention for its low cost and easy implementation. In plenty of existing work, sensor positions, which play an important role in source localization, are usually assumed perfectly known. Unfortunately, they are often subject to uncertainties, which directly leads to effect on localization result. To tackle this problem, we study the RSS-based source localization with sensor position uncertainty. Sensor position uncertainty will be modeled as two types: Gaussian random variable and unknown nonrandom variable. For either of the models, two semidefinite programming (SDP) methods are proposed, i.e., SDP-1 and SDP-2. The SDP-1 method proceeds from the nonconvex problem with respect to the maximum likelihood (ML) estimation and then obtains an SDP problem using proper approximation and relaxation. The SDP-2 method first transfers the sensor position uncertainties to the source position and then obtains an SDP formulation following a similar idea as in SDP-1 method. Numerical examples demonstrate the performance superiority of the proposed methods, compared to some existing methods assuming perfect sensor position information.
Seasonal Decomposition Rates of Broadleaf and Conifer Wood Litter in Far Eastern Tropical Forest Communities
Authors: Putra Putu S. , Achmad Amran , Yamada Toshihiro , Ngakan Putu O.
Published: July 2023

Studies on wood litter decomposition sometimes show conflicting results. While low temperatures and humidity during winter in temperate climates are reported to halt the activity of decomposing agents, in the warmest and wettest tropical regions of the Far East, peat accumulates on the forest floor, indicating that the decomposition process is not proceeding well. In this study, we compared the inter-seasonal and inter-forest communities’ decomposition rate constant (k) of jabon (Anthocephalus macrophyllus (Roxb.) Havil.) and tusam (Pinus merkusii Jungh. & de Vriese) woods in three forest communities (Karst, Lowland, and Pine) on the Indonesian island of Sulawesi. We placed 1,200 wooden planks (600 jabon logs and 600 tusam logs) measuring 10 cm × 10 cm × 1.5 cm on the ground in each forest community during different seasons: dry season and wet season. k was observed seasonally. We also observed the decomposing agent diversity, soil properties, and chemical content of the wood sample to examine factors affecting k values. The results showed the tendency of jabon wood k to be higher in the dry season than in the wet season, and the opposite trend was noted for tusam wood. k of both wood samples was highest in Karst, followed by Lowland and Pine forests. However, except for bacterial diversity and abundance of Odontotermes sp., there was no clear correlation between k and the diversity and abundance of decomposing agents. The k values varied distinctly, even among samples within the same forest community in the same season, causing the data not to be normally distributed. These findings indicate that decomposition processes in tropical forests vary at the microsite scale due to the high diversity of decomposing agents and their complex reciprocal association.

Abstract
We tested the hypotheses that adult cancer incidence and mortality in the Northeast region and in Northern New England (NNE) were different than the rest of the United States (US), and described other related cancer metrics and risk factor prevalence. Using national, publicly available cancer registry data, we compared cancer incidence and mortality in the Northeast region with the US and NNE with the US overall and by race/ethnicity, using age-standardized cancer incidence and rate ratios (RR). Compared to the US, age-adjusted cancer incidence in adults of all races combined was higher in the Northeast (RR 1.07; 95% confidence interval 1.07-1.08) and in NNE (RR 1.06; 1.05-1.07). However, compared to the US, mortality was lower in the Northeast (RR 0.98; 0.98-0.98) but higher in NNE (RR 1.05; 1.03-1.06). Mortality in NNE was higher than the US for cancers of the brain (RR 1.16; 1.07-1.26), uterus (RR 1.32; 1.14-1.52), esophagus (RR 1.36; 1.26-1.47), lung (RR 1.12; 1.09-1.15), bladder (RR 1.23; 1.14-1.33) and melanoma (RR 1.13; 1.01-1.27). Significantly higher overall cancer incidence was seen in the Northeast than the US in all race/ethnicity subgroups except Native American/Alaska Natives (RR 0.68; 0.64-0.72). In conclusion, Northern New England has higher cancer incidence and mortality than the US, a pattern that contrasts with the Northeast region, which has lower cancer mortality overall than the US despite higher incidence.

Introduction: Intradialytic hypertension (IDHTN) is associated with increased risk of adverse outcomes. Patients with IDHTN have higher 44-h blood pressure (BP) than patients without this condition. Whether the excess risk in these patients is due to the BP rise during dialysis per se or on elevated 44-h BP or other comorbid conditions is uncertain. This study evaluated the association of IDHTN with cardiovascular events and mortality and the influence of ambulatory BP and other cardiovascular risk factors on these associations. Methods: 242 hemodialysis patients with valid 48-h ABPM (Mobil-O-Graph-NG) were followed for a median of 45.7 months. IDHTN was defined as: systolic BP (SBP) rise ≥10 mm Hg from pre- to post-dialysis and post-dialysis SBP ≥150 mm Hg. The primary endpoint was all-cause mortality; the secondary endpoint was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, resuscitation after cardiac arrest, heart failure hospitalization, coronary or peripheral revascularization. Results: Cumulative freedom from both the primary and secondary endpoint was significantly lower for IDHTN patients (logrank-p = 0.048 and 0.022, respectively), corresponding to higher risks for all-cause mortality (hazard ratio (HR) = 1.566; 95% confidence interval (CI) [1.001, 2.450]) and the composite cardiovascular outcome (HR = 1.675; 95% CI [1.071, 2.620]) in these individuals. However, the observed associations lost statistical significance after adjustment for 44-h SBP (HR = 1.529; 95% CI [0.952, 2.457] and HR = 1.388; 95% CI [0.866, 2.225], respectively). In the final model after additional adjustment for 44-h SBP, interdialytic weight gain, age, history of coronary artery disease, heart failure, diabetes, and 44-h pulse wave velocity, the association of IDHTN with the outcomes was also not significant and the respective HRs were 1.377 (95% CI [0.836, 2.268]) and 1.451 (95% CI [0.891, 2.364]). Conclusions: IDHTN patients had higher risk for mortality and cardiovascular outcomes but this risk is at least partly confounded by the elevated BP levels during the interdialytic period.

Carta escrita por Gilda de Mello e Souza, remetida ao colega Oswaldo Porchat, que se encontrava em Berkeley, quando a ditadura civil-militar brasileira, recrudescida desde a implantação, em agosto de 1968, do AI-5, representava uma verdadeira ameaça a estudantes e docentes da Universidade de São Paulo, especialmente se lhe fizessem qualquer tipo de oposição. Porchat trocou uma sequência de cartas com Gilda nessa época, nas quais relata sua desilusão com a Faculdade de Filosofia, e com os acontecimentos políticos no Brasil. Ao mesmo tempo, confessa estar encantado com a descoberta de novos elementos da Lógica, e com a atmosfera mais amena dos Estados Unidos. Porchat sabe que Gilda enfrenta momentos difíceis, tendo de assumir a Presidência do curso em meio à tentativa do reitor Miguel Reale de submetê-lo a um interventor. Enfrentando a dúvida sobre se valeria a pena retornar ao Brasil naquele momento, Porchat escreve à amiga. A carta a seguir expressa, dentro do que era possível na época, quando as correspondências eram vigiadas, o parecer de Gilda sobre as indagações do amigo, sobre os rumos da ditadura, e sobre o que ela pensava de sua própria atitude de resistência naquele contexto. A carta original, assim como a sequência de correspondências da qual faz parte, está depositada no Fundo Gilda de Mello e Souza, no Instituto de Estudos Brasileiros (IEB/USP).

Vaping and electronic cigarette (e-cigarette) use have grown exponentially in the past decade, particularly among youth and young adults. Cigarette smoking is a risk factor for both cardiovascular and pulmonary disease. Because of their more limited ingredients and the absence of combustion, e-cigarettes and vaping products are often touted as safer alternative and potential tobacco-cessation products. The outbreak of e-cigarette or vaping product use–associated lung injury in the United States in 2019, which led to >2800 hospitalizations, highlighted the risks of e-cigarettes and vaping products. Currently, all e-cigarettes are regulated as tobacco products and thus do not undergo the premarket animal and human safety studies required of a drug product or medical device. Because youth prevalence of e-cigarette and vaping product use was as high as 27.5% in high school students in 2019 in the United States, it is critical to assess the short-term and long-term health effects of these products, as well as the development of interventional and public health efforts to reduce youth use. The objectives of this scientific statement are (1) to describe and discuss e-cigarettes and vaping products use patterns among youth and adults; (2) to identify harmful and potentially harmful constituents in vaping aerosols; (3) to critically assess the molecular, animal, and clinical evidence on the acute and chronic cardiovascular and pulmonary risks of e-cigarette and vaping products use; (4) to describe the current evidence of e-cigarettes and vaping products as potential tobacco-cessation products; and (5) to summarize current public health and regulatory efforts of e-cigarettes and vaping products. It is timely, therefore, to review the short-term and especially the long-term implications of e-cigarettes and vaping products on cardiopulmonary health. Early molecular and clinical evidence suggests various acute physiological effects from electronic nicotine delivery systems, particularly those containing nicotine. Additional clinical and animal-exposure model research is critically needed as the use of these products continues to grow.
Diagnosis and Management of Cardiovascular Risk in Individuals With Spinal Cord Injury: A Narrative Review

Published: July 2023

More than 16 000 Americans experience spinal cord injury (SCI), resulting in chronic disability and other secondary sequelae, each year. Improvements in acute medical management have increased life expectancy. Cardiovascular disease is a leading cause of death in this population, and seems to occur earlier in individuals with SCI compared with the general population. People with SCI experience a high burden of traditional cardiovascular disease risk factors, including dyslipidemia and diabetes, and demonstrate anatomic, metabolic, and physiologic changes alongside stark reductions in physical activity after injury. They also experience multiple, complex barriers to care relating to disability and, in many cases, compounding effects of intersecting racial and socioeconomic health inequities. Given this combination of risk factors, some investigators have proposed that people with SCI are at increased risk for cardiovascular disease, beyond that associated with traditional risk factors, and SCI could be considered a risk-enhancing factor, analogous to other risk-enhancing factors defined by the 2019 American Heart Association/American College of Cardiology Primary Prevention Guidelines. However, more research is needed in this population to clarify the role of traditional risk factors, novel risk factors, health care access, social determinants of health, and intersectionality of disability, race, and socioeconomic status. There is an urgent need for primary care physicians and cardiologists to have awareness of the importance of timely diagnosis and management of cardiac risk factors for people with SCI.
Analyzing photovoltaic module mechanics using composite plate theories and finite element solutions
Authors: Hartley James Y , Khraishi Tariq
Published: July 2023

Deflection and stress calculated from an experimentally validated, high-fidelity finite element model (FEM) of a photovoltaic module experiencing mechanical load was compared to results from a simplified FEM treating the module laminate as a homogenized composite using a rule of mixtures approach, and further compared to analytical calculations treating the module as a Kirchoff-Love flat plate. The goal of this study was to determine the error incurred by analyzing module mechanics with varying levels of simplification, since resolving the aspect ratios of a module is computationally expensive. Homogenized FEMs were found to underpredict peak deflection under a 1.0 kPa load by between 13 and 19% for lower and upper bound application of the rule of mixtures. However, module shape was captured, implying that a useful replication of a resolved model could be achieved with a reduced, calibrated material stiffness. Homogenized stress results captured glass layer tensile stress components to within 46 to 52% at a sample location of interest, though agreement was poor through the remainder of the laminate due to the lack of material resolution. For plate theory, deflection was overpredicted by 45 to 67% for upper and lower bound homogenizations, and frame-adjacent module shapes were not adequately replicated. Stress results mirrored FEM trends but magnitudes were not well correlated to resolved model values. These results support the use of homogenized laminate models for module shape derivation, though resolved models remain necessary for stress analyses. The accuracy of plate theory was found to be inadequate for most applications.
Influence of fibre orientation, moisture absorption and repairing performance on the low-velocity impact response of woven flax/Elium® thermoplastic bio-composites

Published: July 2023

The importance of natural reinforced bio-composite materials with desirable properties such as high modulus-to-weight ratio, good impact resistance, and the ability to be easily repaired is crucial in the industry. A woven flax/Elium® thermoplastic bio-composite is manufactured to challenge these needs. Elium® is the only resin that permits the manufacture of large parts with thermoset-like processes, as Liquid Resin Infusion presented in that work. The paper highlights the influence of stacking fibre orientation, moisture absorption, and repair aptitude on its impact resistance. An instrumented drop tower was needed to conduct low-velocity impact tests at several energies and high-speed image coupled with microscopic observations was used to assess the damage evolution. The impact resistance was improved for the dry (0/90)6 orientation, but moisture absorption decreased its impact peak force by 20%. A three-point bending test was preferred to compression after impact for studying the residual properties after impact. The bio-composites with (±45)6 orientation showed higher impact residual performance than the (0/90)6 orientation, and corresponded to the reduction of maximum bending force by 20% than that of the reference. In addition, a thermo-compression process was applied to repair the impacted plates and conduct multiple impact/repair cycles which showed a significant recovery of stiffness and maximum impact force at 4J on (0/90)6 plates, highlighting their potential for repair in the automotive and marine industries.
Neoclassical realism, policy paradigms and strategic change: understanding the US rapprochement to Cuba
Authors: Mallett Ellis , Kitchen Nicholas
Published: July 2023

Why do particular foreign policy strategies persist even when they fail to achieve their objectives? And how do such policies eventually come to change? Incorporating policy paradigms as a unifying unit-level intervening variable within a Type II neoclassical realist framework, we account for extended periods of foreign policy continuity despite ongoing policy failure, and theorise the structural conditions necessary to override intervening paradigmatic imperatives. The article illustrates the argument through an analysis of the ‘Obama thaw’, after 50 years of hostile policy towards Havana. Drawing on interviews with key officials, we show that emerging structural pressures in the Western hemisphere brought about the administration’s decision to normalise relations with Cuba.

Objectives:This study aimed to measure the effect of a treatment of adapted physical activity (APA) on motor symptoms and on positive psychological resources in a group of patients with PD. Methods: 37 patients with PD (M age= 71.5; 70.3% male) completed measures of disability level, motor performance, distress, well-being, and quality of life before and after participating in a program of APA (duration: 7 months). Analysis of variance - repeated measures was performed to evaluate the effect of APA on disability, distress, and well-being. Results: After intervention, patients reported significant improvements in their motor autonomy, disability level, psychological distress, and in life appreciation. Discussion: A brief physical activity program was beneficial not only to patients’ motor functioning, but also to their mental health, by reducing distress and promoting life appreciation.
Microbial distribution characteristics related to carbon cycle and their potential impact on methanogenesis of coal reservoirs in underground in situ environments
Authors: Li Yang , Tang Shuheng , Chen Jian , Xi Zhaodong
Published: July 2023

Microorganisms are one of the main driving forces of the cycle of carbon and other life elements in the underground environment. The natural environment is the comprehensive result of these microorganisms. In contrast, the study of coal reservoir microorganisms is mostly under laboratory conditions, which limits people's understanding of the symbiotic relationship between microorganisms, the interaction between microorganisms and the environment, and the distribution differences of microbial communities in the region. Similarly, the carbon cycle of the underground environment driven by essential microorganisms in coal reservoirs cannot be further studied. The geochemical process of underground methane generation and oxidation is critical in discussing the production and consumption of biomethane in the underground environment and the metabolic behavior of microorganisms. For this reason, we conducted biogeochemical tests and microbial sequencing on the water produced by coalbed methane wells in the south of the Qinshui Basin to analyze and improve the understanding of the distribution difference and metabolic behavior of microbial communities in coal reservoirs. The concentration of Cl− and HCO3− in the detention environment in the study area increases, while the concentration of SO42−, NO3−, NO2−, and Fe3+ decreases with the increase of coal seam depth, reflecting the distribution difference of hydrochemical environment and redox conditions of the underground reservoir in the study area. The results of microbial sequencing showed microbial methanogenesis in the study area, but it could also be consumed by microbial oxidation simultaneously. The microbial communities related to methane production and consumption had diversity distributions similar to geochemical parameters and geographical patterns. Methanogens and dissolved inorganic carbon isotopes confirmed the potential of in situ methane generation. Still, biomethane's enrichment and accumulation conditions and the impact of aerobic/anaerobic oxidation of methane need further study.
Numerical study of surrounding rock heat dissipation and wind temperature prediction in high geotemperature coal face
Authors: Wang Hao
Published: July 2023

The heat damage in a coal face of a high-temperature mine is a significant mine disaster owing to various heat sources. Understanding the influence of various heat sources on the air temperature distribution in the coal face can help us to determine reasonable working conditions. Therefore, it is necessary to take into account the coupling relationship of multiple heat sources and obtain accurate prediction results. In this paper, the finite volume calculation method is used to establish a numerical model of heat dissipation of surrounding rock considering the difference in thermal and physical properties of coal and rock in the coal face. And then, a high-temperature coal mine in the northeast of China is taken as an example to explore the airflow temperature distribution law of the coal face under the influence of the absolute heat source and the relative heat source via the finite difference method. Furthermore, an orthogonal test was performed to investigate the influence degree of major factors on heat exchange of the coal face through range analysis. This work supplements the existing numerical model and research, and provides a theoretical basis and more accurate practical methods for predicting the thermal environment of coal face, especially in high mining depth mines.
Attitudes toward Immigrants and Partisan Differences in Information Evaluation
Authors: Asbury-Kimmel Victoria S.
Published: July 2023

Attitudes about immigrants, though related, are not interchangeable with attitudes about immigration. Much research has examined the latter, yet our knowledge regarding what Americans think about immigrants is lacking. Drawing on an original national survey conducted by NORC (n = 2,132) in 2021, I address shortcomings in the literature by illuminating distinct partisan attitudes about immigrants, revealing that Republicans tend to agree with both anti- and worthy-immigrant narratives while Democrats tend to embrace worthy- and reject anti-immigrant narratives. Further, I show how differences in information evaluation are related to the observed phenomena. That is, Republicans tend to interpret prototypical anti-immigrant political rhetoric as commentary about unauthorized immigrants and prototypical pro-immigrant discourse as messaging about immigrants in general and legal immigrants in particular. Democrats, however, interpret anti-immigrant and pro-immigrant narratives to be about immigrants in general. The results complicate understandings of immigration polarization by showing how social psychological mechanisms may facilitate commonality and divergence on attitudes about immigrants.
Descriptive and Symbolic: The Connection Between Political Representation and Citizen Satisfaction with Municipal Public Services
Authors: Forman-Rabinovici Aliza , Beeri Itai
Published: July 2023

While theories of local democracy mark political representation as highly important in determining the quality and perception of public services, little has been done to explore the empirical connection. This represents a lacuna in our understanding of how representation affects citizen wellbeing and how citizens determine their satisfaction with public services. We focus on descriptive and symbolic dimensions of representation to elucidate how representation influences citizens’, and minority citizens’ in particular, experience with public services. Utilizing a survey of residents of Haifa, Israel, our findings imply that beyond the descriptive makeup of municipal elected bodies, symbolic dimensions of representation might be even more important for understanding citizen satisfaction. Symbolic representation may impact satisfaction directly and through its contribution to other feelings about government. These findings expand understandings of the importance of diversity in political representation, determinants of satisfaction and how dynamics of good governance contribute to citizens’ experiences.
Analysis of Doubly Fed Induction Generator-based wind turbine system for fault ride through capability investigations
Authors: Tuka Milkias Berhanu , Endale Salem Molla
Published: July 2023

A Doubly Fed Induction Generator has a stator winding directly coupled with grid whereas rotor is to the grid via a fault-prone converter. In early times, when a fault occurred, these generators were required to disengage from the grid. However, due to the increased penetration, grid operators demanded WTs remain connected to the grid. Thus, this paperwork integrates crowbar protection with a Battery Energy Storage System (BESS) to improve Fault Ride Through (FRT) capability. For performance evaluation under transient conditions, a three-phase symmetrical fault is imposed at a time of 2 seconds. By using the suggested technique, the DC-link voltage is observed to improve and remain at 1150 V with minor fluctuation. Likewise, the stator and rotor currents are observed to remain at their nominal value after 2.15 seconds. MATLAB-Simulink software is used for modeling and simulation by obtaining all the system’s actual parameters from ADAMA-II Wind Farm.
The dynamic connectedness between private equities and other high-demand financial assets: A portfolio hedging strategy during COVID-19
Authors: Papathanasiou Spyros , Vasiliou Dimitrios , Magoutas Anastasios , Koutsokostas Drosos
Published: July 2023

In view of the need for portfolio diversification, we investigate the interlinkages between a private equity ETF and a set of high-demand asset classes including bonds, equities, crude oil, gold, commodities, currency, Bitcoin, and shipping within a spillover framework. For this objective, we apply the enhanced modification of the Diebold and Yilmaz approach for the period 1 January 2010 to 31 January 2023. The empirical findings indicate a modest degree of connectedness among the investigated markets, whereas volatility spillovers showed acceleration during tumultuous periods. In addition, we assess the capacity of private equities for hedging, for the whole sample period and during COVID-19 infectious disease, in order to suggest investors for potential portfolio restructures. Results demonstrate that the short position in the volatility of private equity ETF can result in strong hedging effectiveness for investors holding long positions in Bitcoin, shipping, bonds, and crude oil.

Published: July 2023

Plastic entering the environment is a growing threat for ecosystems. We estimate the annual mass of known Dutch plastic waste generated and littered and where it ends up. We use two methods: (1) a material flow analysis of plastic waste separately collected from 13 economic sectors (including households, industry and imports) and estimate the amount sent to processing plants or exported and (2) a mismanagement model from observations of litter (on Dutch beaches and riverbanks) plus estimates of inadequately managed exported plastic scraps entering the environment abroad. In 2017 (the most recent complete data set available), an estimate of 1990 (±111) kilotonnes [kt] of plastic waste was separately collected. The top three plastic waste generating sectors (74% of the total) were households, clothing and textiles, and importation. Our mismanagement model estimates that 4.3–21.2 kt enters the environment annually; almost all of which occurs in foreign countries after inadequate management of imported Dutch waste. We highlight unknowns, including the source and/or destination of imported (623 kt) and exported (514 kt) plastics, plastics in non-household mixed waste streams and the plastic fraction of some separately collected waste, for example, e-waste. Our results stress the need for improved monitoring and reporting of plastic waste. Beyond the Netherlands, our recommendations could also help other high-income countries’ decision-makers reach their circular economy goals.
Autologous Lipo-Dermal Advancement Flap for Inframammary Fold Reconstruction: A Technical Note for Prevention and Management of Caudal Breast Implant Migration
Authors: Elfieshawy Hatem , Smyth Graham , Jasinska Monika
Published: July 2023

Inferior breast implant displacement, also known as caudal migration, or bottoming-out, is a known complication of breast augmentation. This leads to a loss of upper pole fullness, a more superiorly located nipple-areolar complex, and an unnatural appearance. Avoiding these complaints has been a longstanding challenge in the field of aesthetics and this technical note suggests a novel solution. This technical note describes the process of preoperative assessment, careful markings, and the use of an autologous lipo-dermal advancement flap that has been designed, mobilized, and rotated to be internally fixated to costal margins and the relevant deep fascial structures at the proposed inframammary fold level. This technique creates a robust partitioning hammock-like structure that stabilizes the breast implant and prevents future caudal displacement. The described technique may be implemented as an independent solution, or as an adjunct to other modalities like biological meshes in revision breast surgery.
High-Risk Pulmonary Embolism: Management for the Intensivist
Authors: Khosla Akhil , Zhao Yiyu , Mojibian Hamid , Pollak Jeffrey , Singh Inderjit
Published: July 2023

High-risk pulmonary embolism (PE) also known as massive PE carries a high rate of morbidity and mortality. The incidence of high-risk PE continues to increase, yet the outcomes of high-risk PE continue to remain poor. Patients with high-risk PE are often critically ill, with complex underlying physiology, and treatment for the high-risk PE patient almost always requires care and management from an intensivist. Treatment options for high-risk PE continue to evolve rapidly with multiple options for definitive reperfusion therapy and supportive care. A thorough understanding of the physiology, risk stratification, treatment, and support options for the high-risk PE patient is necessary for all intensivists in order to improve outcomes. This article aims to provide a review from an intensivist's perspective highlighting the physiological consequences, risk stratification, and treatment options for these patients as well as providing a proposed algorithm to the risk stratification and acute management of high-risk PE.
Zone defense: Why liberal cities build too few homes
Authors: Ornstein Joseph T.
Published: July 2023

In this article, I investigate a puzzling feature of American urban politics: cities with more liberal residents tend to enact more restrictive zoning policies and permit fewer new housing units each year than similar conservative cities. To help explain this puzzle, I develop a formal model in which local governments regulate the size of their population to balance the benefits of agglomeration with the costs of congestion. To defend against congestion externalities imposed by new residents, cities enact zoning policies that undersupply housing relative to the social optimum. In liberal cities, where residents value the benefits of agglomeration the most, this undersupply of housing is the most severe.
Holocene precipitation hydrogen isotopic values on Nilgiri Plateau (southern India) suggest a combined effect of precipitation amount and transport paths

Published: July 2023

Paleoclimate investigations of the peat deposits in the Nilgiri Plateau, an important paleoclimate archive of India, are mainly restricted to the carbon isotope composition ((δ13C) of plant-derived materials and pollen studies. However, it is unclear whether these proxies reflect past variability in temperature or hydrology. Here, we report the hydrogen and carbon isotopic variability of n-alkanoic acid of chain length 28 (δDC28 and δ13CC28, respectively) and demonstrate that the peatland leaf wax hydrogen isotopes provide a sensitive record of past hydrology. The decoupling of δ13CC28 and δD of vegetation-corrected rain during the Holocene indicate that δD of the leaf wax compounds mainly respond to past hydrological variability whereas δ13C variations might reflect the temperature-controlled variability of C3 and C4 vegetation. Conforming with the other paleoclimate records from the region, the δDC28 variations showed a reducing precipitation trend since the early Holocene. However, a large amplitude of reconstructed δD of rain (~44‰) during the Holocene indicated changes in the moisture source and trajectory could be an additional factor contributing to the orbital-scale δD variability of proxies from the Indian region.
Between data providers and concerned citizens: Exploring participation in precision public health in Switzerland

Published: July 2023

This empirical article explores the dynamics of exchange and reciprocity between cohorters, that is, study organizers, and cohortees, that is, study participants. Drawing on literature on bioeconomy and valuation, we analyze cohortees’ expectations in return for the “clinical labor” they perform in the pilot phase of a Swiss precision public health study. Based on an ethnography of this cohort and data from seven focus groups with cohortees ( n = 37), we identified four positions: (1) the good citizen participant, (2) the critical participant, (3) the concerned participant, and (4) the self-oriented participant. These reveal that cohortees’ participation, still framed in altruistic terms, nevertheless engages expectations about reciprocal obligations of the state and science in terms of public health, confirming the deep entanglement of gift-based, financial, and moral economies of participation. The different values emerging from these expectations—robust scientific evidence about environmental exposure and a socially oriented public health—provide rich indications about stake making which might matter for the future of precision public health.
Ethical climate in healthcare: A systematic review and meta-analysis
Authors: Essex Ryan , Thompson Trevor , Evans Thomas Rhys , Fortune Vanessa , Kalocsányiová Erika , Miller Denise , Markowski Marianne , Elliott Helen
Published: July 2023

Background

Ethical climate refers to the shared perception of ethical norms and sets the scope for what is ethical and acceptable behaviour within teams.

Aim

This paper sought to explore perceptions of ethical climate amongst healthcare workers as measured by the Ethical Climate Questionnaire (ECQ), the Hospital Ethical Climate Survey (HECS) and the Ethics Environment Questionnaire (EEQ).

Methods

A systematic review and meta-analysis was utilised. PSYCINFO, CINAHL, WEB OF SCIENCE, MEDLINE and EMBASE were searched, and papers were included if they sampled healthcare workers and used the ECQ, HECS or EEQ.

Ethical consideration

Ethical approval was not required.

Results

The search returned 1020 results. After screening, 61 papers were included ( n = 43 HECS, n = 15 ECQ, n = 3 EEQ). The overall sample size was over 17,000. The pooled mean score for the HECS was 3.60. Mean scores of individual studies ranged from 2.97 to 4.5. For the HECS studies, meta-regression was carried out. No relationship was found between the country of the studies, the study setting (ICU v non-ICU settings) or the mean years of experience that the sample had. For the ECQ, sub-scales had mean scores ranging from 3.41 (instrumental) to 4.34 (law) and were all observed to have significant and substantial heterogeneity. Three studies utilised the EEQ so further analysis was not carried out.

Conclusions

The above results provide insight into the variability of scores as measured by the HECS, ECQ and EEQ. To some extent, this variability is not surprising with studies carried out across 21 countries and in a range of healthcare systems. Results also suggest that it may be that more local and context specific factors are more important when it comes to predicting ethical climate.
