Logistic regression with sparse common and distinctive covariates
Authors: Park S. , Ceulemans E. , Van Deun K.
Published: February 2023

Having large sets of predictor variables from multiple sources concerning the same individuals is becoming increasingly common in behavioral research. On top of the variable selection problem, predicting a categorical outcome using such data gives rise to an additional challenge of identifying the processes at play underneath the predictors. These processes are of particular interest in the setting of multi-source data because they can either be associated individually with a single data source or jointly with multiple sources. Although many methods have addressed the classification problem in high dimensionality, the additional challenge of distinguishing such underlying predictor processes from multi-source data has not received sufficient attention. To this end, we propose the method of Sparse Common and Distinctive Covariates Logistic Regression (SCD-Cov-logR). The method is a multi-source extension of principal covariates regression that combines with generalized linear modeling framework to allow classification of a categorical outcome. In a simulation study, SCD-Cov-logR resulted in outperformance compared to related methods commonly used in behavioral sciences. We also demonstrate the practical usage of the method under an empirical dataset.
Computer anthropomorphisation in a socio-economic dilemma
Authors: Cogoni Carlotta , Fiuza Angelica , Hassanein Leslie , Antunes Marília , Prata Diana
Published: February 2023

In the study of human behaviour, non-social targets are often used as a control for human-to-human interactions. However, the concept of anthropomorphisation suggests that human-like qualities can be attributed to non-human objects. This can prove problematic in psychological experiments, as computers are often used as non-social targets. Here, we assessed the degree of computer anthropomorphisation in a sequential and iterated prisoner’s dilemma. Participants (N = 41) faced three opponents in the prisoner’s dilemma paradigm—a human, a computer, and a roulette—all represented by images presented at the commencement of each round. Cooperation choice frequencies and transition probabilities were estimated within subjects, in rounds against each opponent. We found that participants anthropomorphised the computer opponent to a high degree, while the same was not found for the roulette (i.e. no cooperation choice difference vs human opponents; p = .99). The difference in participants’ behaviour towards the computer vs the roulette was further potentiated by the precedent roulette round, in terms of both cooperation choice (61%, p = .007) and cooperation probability after reciprocated defection (79%, p = .007). This suggests that there could be a considerable anthropomorphisation bias towards computer opponents in social games, even for those without a human-like appearance. Conversely, a roulette may be a preferable non-social control when the opponent’s abilities are not explicit or familiar.
Disentangling word stress and phrasal prosody: A view from Georgian
Authors: Borise Lena
Published: February 2023

This paper investigates the interaction of word stress and phrasal prosody in Georgian by studying the distribution of acoustic cues (duration, intensity, F0) in controlled data. The results show that initial syllables in Georgian words are marked by greater duration than all subsequent syllables, regardless of syllable count and phrasal context. After excluding domain-initial strengthening as an alternative explanation, this finding provides evidence in favor of fixed initial stress. Likewise, initial syllables are marked by greatest intensity, but the consistent gradual drop in intensity throughout the word suggests that this effect may not be stress-related. The F0 results align with the existing accounts: individual lexical words form ACCENTUAL PHRASES, marked by a low pitch accent on the initial syllable and a high final boundary tone on the final syllable. Additionally, new evidence for a phrasal accent, aligned with the penult, is presented. F0 targets are shown to be completely absent in the context of post-focal deaccenting, which shows that F0-marking in Georgian is reserved for phrasal prosody and is not intrinsic to stress-marking. These results help account for the facts related to word stress, phrasal intonation, and their interplay in Georgian, the object of debate in the literature.
On the issue of definition subject and object of legal regulation in the draft Labor Code of Ukraine
Authors: Golosnichenko Dmytro
Published: February 2023

The author examines the state of legal regulation of social labor relations. It is emphasized that legal reform is being gradually implemented in Ukraine. It particularly affects those areas of law that are related to human and civil rights. Among these rights, the right to work occupies a special place. The Constitution of Ukraine has several articles aimed at regulating labor relations and human health. It is especially necessary to allocate Art. 43 of our Basic Law, which proclaims this right, establishes constitutional guarantees for citizens to exercise their right to work, prohibit forced labor and protect the health of workers. «Everyone has the right to work, including the opportunity to earn a living by work which he freely chooses or freely agrees to». However, enshrining the right to work in the general law is insufficient. The current Labor Code of Ukraine is clearly outdated. The necessity of adopting a new codified legal act, which should regulate labor relations, is proved. The subject and object of law in general, the subject and object of labor law and the Labor Code of Ukraine are studied. At this stage of development of Ukrainian society, it is necessary to adopt a new codified legal act that would fully regulate relations in the field of labor. The draft law of such a legal act (the draft Labor Code of Ukraine — hereinafter LCU) was developed by experts, but due to its imperfections, the legislator postponed its adoption. It is thought that first of all it is necessary to more clearly define the subject and object of legal regulation of the LCU. Without objecting mainly to their definition, the LCU offers clarifications. The authors of the bill list what relates to the object of labor relations, and at the end note: «other issues defined by this Code». It should be noted that «issues» cannot be the object of a relationship. After all, in the Ukrainian language «question» is «a form of thought expressed in the language of a sentence, which is uttered or written when they want to ask something, that is, to obtain information of interest». Not all objects of labor relations should be listed when defined in Part 2 of Art. 1 LCU. However, it is inappropriate to point out that these objects include «questions». It is suggested to replace the phrase «other issues defined by this Code» with the words: «other objects of relations related to labor law».

Key words: the object of legal regulation, the subject of legal regulation, labor legal relations, the right to work, the draft Labor Code of Ukraine.
Experimental Study to Improve Solar Photovoltaic Performance by Utilizing PCM and Finned Wall

Published: February 2023

The temperature of a photovoltaic (PV) module has a significant impact on the module's ability to produce electricity. PV cells module’s passive cooling is critical for increasing electrical efficiency and power output. In this work, two scenarios of the passive cooling technique were presented for use in the cooling of the monocrystalline silicon PV modules. An aluminium finned wall and a combination of aluminium ﬁnned wall with phase change material were connected to the backside of the PV in order to bring the working temperature down and maintain it under the hot climate conditions in southern Iraq. Paraffin wax was employed as a PCM placed into an aluminium container with internal and exterior longitudinal aluminium fins in order to enhance the PCM's poor thermal conductivity, speed up the rates at which it melts and solidifies, and increase the amount of heat that is dissipated through free convection heat transfer. The PV modules were simultaneously tested and compared with a PV reference module under different solar radiation. According to the findings, the average temperature of the PV-Aluminium Finned wall-PCM module is reduced by 19.9 degrees Celsius when compared with the temperature of the reference PV module. This results in an increase in the average maximum output power of up to 23.1% compared to an identical reference PV module. Furthermore, the average electrical efficiency of the PV-Aluminium Finned wall-PCM is enhanced by 23.2% during the testing time from 9:00 AM to 12:00 PM in July 2022 at maximum solar radiation of 1130.7 W/m2 when compared with the PV reference module under the same conditions. This indicates a significant increase in both electrical and thermal performance. The testing took place in July 2022.
Numerical Investigation on Thermal and Electrical Stress in Electric Vehicle Cabling Network
Authors: Mahipal Bukya  , Rajesh Kumar  , Akhilesh Mathur
Published: February 2023

Global warming and an impending energy problem have compelled nations to become greener and cleaner. Worldwide, interest in electric vehicles (EVs) is growing as a result of rising gasoline prices and environmental concerns. The need for electrical components and cabling networks is expanding along with the demand for electrified vehicles. The complexity of vehicle electrical, electronics, and control circuits is also rising. There are many wire and cable performance issues in modern e-mobility, including limited space, vibration, high-temperature variation, unfriendly fluids, and rising data transmission requirements. Thus, it is important to study and evaluate the thermal and electrical stresses in the electric vehicles cabling network to avoid insulation failure, which causes fire accidents in the electric components of EVs. An EV's entire electrical system gets hotter, and insulation strength is affected by both temperature and the electrical field. The insulation system is one of the most important components in any electrified vehicle. From a design and protection perspective, the computation of electric potential distribution and electric field within and around the cables of electric vehicles is very important. The strong non-linear dependency of the electrical conductivity of the insulation material on prevailing electrical stress and temperature makes the field problem not only coupled but also non-linear. Finite Difference Numerical (FDM) is used for non-linear field computation. In this paper, different electric vehicle cabling network layouts were studied and listed the challenges. Chosen the high voltage cables of electric vehicles from the cabling network and numerically computed the conductivity, temperature, and electrical fields of cable.

Tracking Hidden Magnetospheric Fluctuations in Accretion-powered Pulsars With a Kalman Filter
Authors: Melatos A. , O’Neill N. J. , Meyers P. M. , O’Leary J.
Published: February 2023

X-ray flux and pulse period fluctuations in an accretion-powered pulsar convey important information about the disk–magnetosphere interaction. It is shown that simultaneous flux and period measurements can be analysed with a Kalman filter based on the standard magnetocentrifugal accretion torque to generate accurate time-dependent estimates of three hidden state variables, which fluctuate stochastically and cannot be measured directly: the mass accretion rate, the Maxwell stress at the disk–magnetosphere boundary, and the radiative efficiency of accretion onto the stellar surface. The inferred fluctuation statistics carry implications for the physics of hydromagnetic instabilities at the disk–magnetosphere boundary and searches for continuous gravitational radiation from low-mass X-ray binaries.
A Study of Stellar Spins in 15 Open Clusters
Authors: Healy Brian F. , McCullough P. R. , Schlaufman Kevin C. , Kovacs Geza
Published: February 2023

We analyze spectroscopic and photometric data to determine the projected inclinations of stars in 11 open clusters, placing constraints on the spin-axis distributions of six clusters. We combine these results with four additional clusters studied by Healy & McCullough and Healy et al. to perform an ensemble analysis of their spins. We find that eight out of 10 constrained clusters (80%) have spin-axis orientations consistent with isotropy, and we establish a lower limit of four out of 10 (40%) isotropic clusters at 75% confidence, assuming no correlation of spins between clusters. We also identify two clusters whose spin-axis distributions can be better described by a model consisting of an aligned fraction of stars combined with an isotropic distribution. However, the inclination values of these stars may be influenced by systematic error, and the small number of stars modeled as aligned in these two clusters precludes the interpretation that their stellar subsets are physically aligned. Overall, no cluster displays an unambiguous signature of spin alignment, and 97% of the stars in our sample are consistent with isotropic orientations in their respective clusters. Our results offer support for the dominance of turbulence over ordered rotation in clumps and do not suggest the alignment of rotation axes and magnetic fields in protostars.

Our understanding of the kinematic properties of multiple stellar populations (mPOPs) in Galactic globular clusters (GCs) is still limited compared to what we know about their chemical and photometric characteristics. Such limitation arises from the lack of a comprehensive observational investigation of this topic. Here we present the first homogeneous kinematic analysis of mPOPs in 56 GCs based on high-precision proper motions computed with Hubble Space Telescope data. We focused on red-giant-branch stars, for which the mPOP tagging is clearer, and measured the velocity dispersion of stars belonging to first (1G) and second generations (2G). We find that 1G stars are generally kinematically isotropic even at the half-light radius, whereas 2G stars are isotropic at the center and become radially anisotropic before the half-light radius. The radial anisotropy is induced by a lower tangential velocity dispersion of 2G stars with respect to the 1G population, while the radial component of the motion is comparable. We also show possible evidence that the kinematic properties of mPOPs are affected by the Galactic tidal field, corroborating previous observational and theoretical results suggesting a relation between the strength of the external tidal field and some properties of mPOPs. Although limited to the GCs’ central regions, our analysis leads to new insights into the mPOP phenomenon, and provides the motivation for future observational studies of the internal kinematics of mPOPs.
Deep Search for Gamma-Ray Emission from the Accreting X-Ray Pulsar 1A 0535+262
Authors: Hou X. , Zhang W. , Torres D. F. , Ji L. , Li J.
Published: February 2023

Binary systems are a well-established subclass of gamma-ray sources. The high mass X-ray binary pulsar 1A 0535+262 has been considered to be a possible gamma-ray emitter for a long time, although former gamma-ray searches using the Fermi Large Area Telescope (LAT) and VERITAS data resulted in upper limits only. We aim at a deep search for gamma-ray emission and pulsations from 1A 0535+262 using more than 13 yr of Fermi-LAT data. The analysis was performed for both the whole Fermi-LAT data set, as well as for the X-ray outbursts that 1A 0535+262 has experienced since the launch of Fermi. Various X‐ray observations have been used to generate the ephemeris for the pulsation search. We also investigate the long-term gamma-ray flux variability and perform orbital phase-resolved analysis for the outbursts. We did not detect any steady or pulsed gamma-ray emission from 1A 0535+262 during the whole Fermi-LAT mission span or its X-ray outbursts. We thus derived the deepest gamma-ray luminosity upper limits to date at the 95% confidence level to be around (2.3–4.7) × 1032 erg s−1 depending on different spectral indices assumed, which results in a ratio of L

Catalog of Magnetic White Dwarfs with Hydrogen Dominated Atmospheres
Authors: Amorim L. L. , Kepler S. O. , Külebi Baybars , Jordan S. , Romero A. D.
Published: February 2023

White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other and with other stellar features, we determined the magnetic field strength for a total of 804 hydrogen-rich white dwarfs (WDs) of which 287 are not in the literature. We fitted the spectra observed with the Sloan Digital Sky Survey using atmospheric models that consider the Zeeman effect due to the magnetic field at each point in the stellar disk. Comparing magnetic and nonmagnetic WDs, the literature already shows that the magnetic ones have on average higher mass than the nonmagnetic. In addition to that, magnetic fields are more common in cooler WDs than in hotter WDs. In consonance, we found that those with higher magnetic field strengths tend to have higher masses, and lower temperatures, for which models indicate the crystallization process has already started. This reinforces the hypothesis that the field is being generated and/or amplified in the cooling process of the white dwarf. Our sample constitutes the largest number of white dwarfs with determined magnetic fields to date.
Jets and Rings in Images of Spinning Black Holes
Authors: Papoutsis Evan , Bauböck Michi , Chang Dominic , Gammie Charles F.
Published: February 2023

We develop a “dual-cone” model for millimeter wavelength emission near a spinning black hole. The model consists of optically thin, luminous cones of emission, centered on the spin axis, which are meant to represent jet walls. The resulting image is dominated by a thin ring. We first consider the effect of the black hole’s spin on the image and show that the dominant effect is to displace the ring perpendicular to the projection of the spin axis on the sky by

. This effect is lower order in a

We then show that the centerline of the jet can provide a suitable reference: its location is exactly independent of spin if the observer is outside the cone and nearly independent of spin if the observer is inside the cone. If astrophysical uncertainties can be controlled, then spin displacement is large enough to be detectable by future space very long baseline interferometry missions. Finally, we consider ring substructure in the dual-cone model and show that features in total intensity are not universal and depend on the cone-opening angle.
Relativistic Correction to the r-mode Frequency in Light of Multimessenger Constraints
Authors: Ghosh Suprovo , Pathak Dhruv , Chatterjee Debarati
Published: February 2023

The r-mode oscillations of rotating neutron stars are promising candidates for continuous gravitational-wave (GW) observations. The r-mode frequencies for slowly rotating Newtonian stars are well known and independent of the equation of state (EOS), but for neutron stars several mechanisms can alter the r-mode frequency for which the relativistic correction is dominant and relevant for most of the neutron stars. The most sensitive searches for continuous GWs are those for known pulsars for which GW frequencies are in targeted narrow frequency bands of a few hertz. In this study, we investigate the effect of several state-of-the-art multimessenger constraints on the r-mode frequency for relativistic, slowly rotating, barotropic stars. Imposing these recent constraints on the EOS, we find that the r-mode frequency range is slightly higher than that from the previous study and the narrowband frequency range can increase by up to 25% for the most promising candidate PSR J0537−6910 depending on the range of compactness. We also derive universal relations between r-mode frequency and dimensionless tidal deformability that can be used to estimate the dynamical tide of the r-mode resonant excitation during the inspiral signal. These results can be used to construct the parameter space for r-mode searches in GW data and also constrain the nuclear EOS following a successful r-mode detection.

Antarctic Penguin Biogeography Project: Database of abundance and distribution for the Adélie, chinstrap, gentoo, emperor, macaroni, and king penguin south of 60 S
Authors: Che-Castaldo Christian , Humphries Grant , Lynch Heather , Humphries Grant
Published: February 2023

The Antarctic Penguin Biogeography Project is an effort to collate all known information about the distribution and abundance of Antarctic penguins through time and to make such data available to the scientific and management community. The core data product involves a series of structured tables with information on known breeding sites and surveys conducted at those sites from the earliest days of Antarctic exploration through to the present. This database, which is continuously updated as new information becomes available, provides a unified and comprehensive repository of information on Antarctic penguin biogeography that contributes to a growing suite of applications of value to the Antarctic community. One such application is the Mapping Application for Antarctic Penguins and Projected Dynamics (MAPPPD; www.penguinmap.com), a browser-based search and visualization tool designed primarily for policymakers and other non-specialists, and mapppdr, an R package developed to assist the Antarctic science community. This dataset contains records of Pygoscelis adeliae, Pygoscelis antarctica, Pygoscelis papua, Eudyptes chrysolophus, Aptenodytes patagonicus, and Aptenodytes forsteri annual nest, adult, and/or chick counts conducted during field expeditions or collected using remote sensing imagery, that were subsequently gathered by the Antarctic Penguin Biogeography Project from published and unpublished sources, at all known Antarctic penguin breeding colonies south of 60 S from 1892-11-01 to 2022-02-12. 

This dataset collates together all publicly available breeding colony abundance data (1979-2022) for Antarctic penguins in a single database with standardized notation and format. Colony locations have been adjusted as necessary using satellite imagery, and each colony has been assigned a unique four-digit alphanumeric code to avoid confusion. These data include information previously published in a variety of print and online formats as well as additional survey data not previous published. Previously unpublished data derive primarily from recent surveys collected under the auspices of the Antarctic Site Inventory, Penguin Watch, or by the Lynch Lab at Stony Brook University.

P
=.000). A lower visual analog scale pain score in group B was noticed on POD 1 (
P
=.000) and POD 2 (
P
=.005). Range of motion (
P
=.019) and Lysholm score (
P

Global Health Competencies and Educational Needs for Nursing Students in South Korea
Authors: Lee Sujin , Kim Eunjoo , Yoon Ju Young
Published: February 2023

Background:

Despite the increasing demand for global health education, relatively few global health courses currently are offered in Korea.

Method:

This mixed-methods study examined the need for global health competency and global health education experience for nursing students. A survey of 208 nursing students was conducted from May 2020 to August 2020, and three focus groups were conducted with 12 nursing students.

Results:

The average score of global health nursing competencies was 2.8 ± 0.7 on a scale ranging from 1 to 4. Female, higher academic achievement, fluent English, and higher global health education experience had a significant effect on global health competency. The most influential factor was more experience with global health education. Nursing students' perceptions and educational needs related to global health education were classified into four subthemes.

Conclusion:

The development of global health education programs for nursing students is needed.

Bilensectomy: Safety and Visual Outcomes in Angle-Supported, Iris-Fixated, and Posterior Chamber Phakic Intraocular Lenses
Authors: Vargas Veronica , Alió Jorge L. , Alió del Barrio Jorge L. , Cantó-Cerdán Mario , Barraquer Rafael I. , Duch Francisco , Marinho Antonio
Published: February 2023

Purpose:

To report the visual and refractive outcomes, intraoperative and postoperative complications, and main causes of bilensectomy in the different types of phakic intraocular lenses (pIOLs).

Methods:

This was a retrospective multicenter study that included 234 eyes of 185 patients that underwent bilensectomy. Patients were divided into three groups depending on the pIOL that was explanted (angle-supported, iris-fixated, or posterior chamber). The main reasons leading to the indication for bilensectomy, time elapsed between pIOL implantation and bilensectomy, intraoperative and postoperative complications, uncorrected and corrected distance visual acuity (UDVA and CDVA), and endothelial cell density loss 1 year after bilensectomy were evaluated.

Results:

There was a statistically significant improvement in UDVA and CDVA after bilensectomy in all groups. Cataract development was the main reason for bilensectomy, followed by significant endothelial cell density loss. Time between pIOL implantation and bilensectomy was significantly greater in eyes with an anterior chamber pIOL.

Conclusions:

Bilensectomy outcomes in general are good. Iris-fixated lenses, particularly hyperopic, are more prone to intraoperative complications and endothelial cell loss than the other pIOLs models. The results show that bilensectomy is a safe and effective procedure with a relatively low rate of intraoperative and postoperative complications and acceptable refractive predictability.

Published: February 2023

Purpose:

To evaluate clinical retinal optical image quality following implantation of an extended depth of focus intraocular lens (EDOF IOL) (Vivity; Alcon Laboratories, Inc), and to compare it with a monofocal and a trifocal IOL.

Methods:

This prospective, comparative, case-control study included 88 eyes implanted with: (1) 19 monofocal IOLs (AcrySof SA60AT; Alcon Laboratories, Inc); (2) 38 EDOF IOLs (AcrySof IQ Vivity); and (3) 31 trifocal IOLs (AT LISA tri 839MP; Carl Zeiss Meditec AG). Total root mean square, ocular lower (LOA) and higher (HOA) order aberrations, point spread function (PSF) Strehl ratio (PSF with LOA), and PSF Strehl ratio excluding LOA (PSF without LOA) were analyzed using a Pyramidal WaveFront-based sensor aberrometer Osiris (Costruzione Strumenti Oftalmici) at two different pupil sizes (3 and 4 mm).

Results:

The trifocal IOL showed the highest PSF without LOA at both pupil sizes (0.52 ± 0.12 and 0.31 ± 0.07, respectively), followed by the AcrySof SA60AT (0.39 ± 0.10 and 0.27 ± 0.07) and AcrySof IQ Vivity (0.34 ± 0.11 and 0.24 ± 0.09) (
P
< .001). The AcrySof IQ Vivity and monofocal IOLs were comparable (
P
> .05). Despite the comparable postoperative low spherical equivalent among the IOL groups, the AT LISA tri 839MP retinal image quality (PSF with LOA) was the most severely affected by such residual refractive errors (dropped to 0.26 ± 0.06 at 3 mm;
P
< .001) compared to the monofocal AcrySof SA60AT (0.24 ± 0.07 at 3 mm) and EDOF Acrysof IQ Vivity (0.23 ± 0.06 at 3 mm) groups. The PSF with LOA was comparable (
P
> .05) among the three groups at both the 3-and 4-mm pupil size.

Conclusions:

Although trifocal IOLs provided significantly better retinal image quality if influence of LOA is excluded, they also demonstrated to be the most sensitive to residual refractive errors. Both the EDOF Acrysof IQ Vivity and mono-focal AcrySof SA60AT IOLs showed a comparable retinal image quality, and they are also comparable with trifocal IOLs when considering the clinically real PSF (PSF with LOA).

Published: February 2023

Background

Extracorporeal membrane oxygenation (ECMO) combined with COVID-19 presents challenges (eg, isolation, anticipatory grief) for patients and families.

Objective

To (1) describe characteristics and outcomes of patients with COVID-19 receiving ECMO, (2) develop a practice improvement strategy to implement early, semistructured palliative care communication in ECMO acknowledgment meetings with patients’ families, and (3) examine family members’ experiences as recorded in clinicians’ notes during these meetings.

Methods

Descriptive observation of guided, in-depth meetings with families of patients with COVID-19 receiving ECMO, as gathered from the electronic medical record of a large urban academic medical center. Most meetings were held within 3 days of initiation of ECMO.

Results

Forty-three patients received ECMO between March and October 2020. The mean patient age was 44 years; 63% of patients were Hispanic/Latino, 19% were Black, and 7% were White. Documentation of the ECMO acknowledgment meeting was completed for 60% of patients. Fifty-six percent of patients survived to hospital discharge. Family discussions revealed 7 common themes: hope, reliance on faith, multiple family members with COVID-19, helping children adjust to a new normal, visitation restrictions, gratitude for clinicians and care, and end-of-life discussions.

Conclusion

Early and ongoing provision of palliative care is feasible and useful for highlighting a range of experiences related to COVID-19. Palliative care is also useful for educating patients and families on the benefits and limitations of ECMO therapy.

Published: February 2023

Acalypha indica (Indian Nettle in English, Kuppaimeni in Tamil, Kuppameniya in Sinhala) leaves are locally used as herbal remedy. It can induce hemolysis and methemoglobinemia in a Glucose-6-Phosphate Dehydrogenase (G6PD) deficient person. Here we report a 46-year-old-male was presented with hemolysis and methemoglobinemia following Acalypha indica ingestion. Later, he was found to have G6PD deficiency. He completely recovered with supportive treatment.

Published: February 2023

The anemia of critical illness (ACI) is a nearly universal pathophysiological consequence of burn injury and a primary reason burn patients require massive quantities of transfused blood. Inflammatory processes are expected to drive postburn ACI and prevent meaningful erythropoietic stimulation through iron or erythropoietin supplementation, but to this day no specific inflammatory pathways have been identified as a critical mechanism. In this study, we examined whether secretion of G-CSF and IL-6 mediates distinct features of postburn ACI and interrogated inflammatory mechanisms that could be responsible for their secretion. Our analysis of mouse and human skin samples identified the burn wound as a primary source of G-CSF and IL-6 secretion. We show that G-CSF and IL-6 are secreted independently through an IL-1/MyD88–dependent mechanism, and we ruled out TLR2 and TLR4 as critical receptors. Our results indicate that IL-1/MyD88–dependent G-CSF secretion plays a key role in impairing medullary erythropoiesis and IL-6 secretion plays a key role in limiting the access of erythroid cells to iron. Importantly, we found that IL-1α/β neutralizing Abs broadly attenuated features of postburn ACI that could be attributed to G-CSF or IL-6 secretion and rescued deficits of circulating RBC counts, hemoglobin, and hematocrit caused by burn injury. We conclude that wound-based IL-1/MyD88 signaling mediates postburn ACI through induction of G-CSF and IL-6 secretion.
Cowongan in Javanese Islamic mysticism: A study of Islamic philosophy in Penginyongan society
Authors: Supriyanto Supriyanto
Published: February 2023

This study aims to reveal the interaction of local Javanese culture with an Islamic philosophical approach originating from the Cowongan tradition performed by shamans accompanied by dances with holy ladies and reciting mantras. This tradition is a prayer asking the gods to send down rain. This article emphasised that the Cowongan tradition places mystical power as the dominant element in life, which is embodied in symbols. The study of mysticism is closer to the study of Sufism which presents it as Islamic mysticism with the color of syncretism of religious teachings with local cultural practices embodied by mystical-occult practices as the Penginyongan culture.Contribution: This research contributed to the fact that traditions that are good and acceptable to society can become the law as part of the Urf, which need to be maintained as long as they do not conflict with Sharia.
