On the Relation Between the Hard Problem of Consciousness and the Combination Problem for Panpsychism
Authors:   Voronezh State Pedagogical University, Sysoev Matvey S.
Published: May 2023

The paper compares two problems in the analytical philosophy of mind: the hard problem of consciousness and the combination problem for panpsychism. The former arises for a wide range of materialist approaches, including physicalism. Panpsychism is asserted by its proponents as the best solution to the combination problem. However, panpsychism itself is faced with the combination problem. A comparison of these problems demonstrates that constitutive panpsychism is fundamentally incapable of solving the hard problem of consciousness. This is demonstrated by the structural and substantive similarity of the arguments in favour of each problem. The author shows that constitutive panpsychism is an extension of physicalism specifically designed to solve the hard problem. Further, the arguments from conceivability in favour of the hard and combination problems are compared, demonstrating their structural similarity. In addition, the author points out the substantive similarity of these problems by comparing individual types of argumentations. This allows us to accept the hypothesis that one of the reasons for the problems of panpsychism and physicalism may lie in mereological atomism, which unites these approaches. Thus, the association of the hard and combination problems can serve as an argument against mereological atomism in both panpsychism and physicalism. Based on the analysis of both problems, general conclusions are drawn about the prospects for the approaches in question and a direction of research is proposed in which the general problems of constitutive panpsychism and physicalism could be solved. It is shown that there is at least one acceptable naturalistic alternative to atomism: priority monism, which can be a strategy for solving the considered problems for both physicalism and panpsychism.
The Failed State Problem in the Foreign Policies of Russia and the USA in the Late 20th and Early 21st Centuries
Authors:   Saint-Petersburg State University of Aerospace Instrumentation, Luk’yanov Vladimir Yu.
Published: May 2023

This article analyses the problem of the so-called failed state in modern international relations. The failed state problem is considered here as one of the most important factors influencing geopolitics today. The paper provides a brief overview of studies into this issue and elaborates on the role of the failed state in the foreign policies of Russia and the United States at the present stage. The high level of tension in the US–Russia relations is pointed out; the use of failed states by the two parties as a tool for achieving their geopolitical goals is analysed. The problem is considered in a historical and political retrospective, from the Cold War period to the present day. In the foreign policy of the USA in the late 20th and early 21st centuries, the failed state factor was used to support the country’s claim for global dominance after the collapse of the bipolar system of international relations and for the right to conduct military operations regardless of the stance of the global community and the United Nations. In the case of Russia, the paper demonstrates the importance of the failed state factor in the country’s foreign policy on the post-Soviet states, primarily when it comes to the political crises in Ukraine. The author concludes that the problem is largely contrived, while failed states are being used primarily as a foreign policy tool by the key geopolitical actors. Lastly, the author suggests ways to solve this problem in the current geopolitical situation, especially in the context of the foreign policies of Russia and the USA.
Translating spatial navigation evaluation from experimental to clinical settings: The virtual environments navigation assessment (VIENNA)
Authors: Rekers Sophia , Finke Carsten
Published: May 2023

Spatial navigation abilities are frequently impaired in neurological disorders and they also decline with normal aging. Researchers and clinicians therefore need valid and easy-to-use spatial navigation assessment tools to study the impact of different neuropathologies and prevent relevant cognitive impairments from going undetected. However, current experimental paradigms rarely address which cognitive processes they recruit, often have resource-intensive setups, and usually require active navigation, e.g., using a joystick or keyboard, thus confounding cognitive performance with fine motor skills. Yet, for clinical feasibility, time-efficient paradigms are needed that are informative and easy to administer in participants with limited technical experience and diverging impairments. Here, we introduce the virtual environments navigation assessment (VIENNA), a virtual adaptation of a brief, standardized, and intuitive spatial navigation paradigm (https://osf.io/kp4c5/). VIENNA is designed to assess spatial navigation without episodic memory demands, requires no interface device, and takes about 16 min to complete. We evaluated VIENNA in 79 healthy middle-aged to older participants (50–85 years) and provide evidence for its feasibility and construct validity. Tests of visuospatial and executive functions, but not episodic memory or selective attention, were identified as cognitive correlates of VIENNA, even when controlling for participant age and overall cognitive performance. Furthermore, VIENNA scores correlated with subjective navigation ability and age, but not with depressiveness, cognitive complaints, or education. The straightforward administration of VIENNA allows for its integration into routine neuropsychological assessments and enables differentiated evaluation of spatial navigation performance in patients with motor impairments and episodic memory deficits.

Sedimentation has continuously resulted in siltation of the port of Pelabuhan Perikanan Samudera (PPS) Lampulo located in Kuta Alam District, Banda Aceh City. The dredged soil collected outside the port area visually indicates clay soil. In addition to the low bearing capacity and high plasticity, the effect of water on clay is high swelling and shrinkage. One of the prominent behaviors that cause major damage to structures built on clay is associated with volume decrease i.e., shrinkage in saturated compressible clay soil when water get evaporated. Shrinkage in clay will result in volume changes. The purpose of this research is to calculate the volume changes in mound of clay soil based on shrinkage limit values using SNI 3422:2008. The soil sample used is an undisturbed sample (UDS) originating from the dredging area of the port of PPS Lampulo. The test consists of water content, specific gravity, liquid limit, plastic limit, shrinkage limit and grain size distribution using the SNI method. Based on the results of the index properties test, according to AASHTO the soil sample belongs to group A-7-5 which means it is a clay soil with a GI value greater than 20, so it is considered poor as a subgrade soil. According to USCS, the soil belongs to the CH classification, which means clay soil with high plasticity, so it has a large potential for expansion and shrinkage. Based on SNI 3422:2008, the average shrinkage limit (SL) is 21.21%, the average shrinkage ratio (R) is 2.27% and the average linear shrinkage (LS) is 9.65%. With an average volume change (VC) value of 35.59%, the shrinkage volume of soil embankment of the dredging area of the port of PPS Lampulo is 32,438.85 m3 compared to its initial volume (91,145.97 m3). Therefore, the shrinkage limit is an important parameter for calculating the volume shrinkage in mound of soil due to the soil type is clay with high plasticity.

The aim of this study was to analyze the accuracy, precision, and consequently the reliability of five traditional apex locators (AL) and one integrated AL in determining working length (WL). Materials and Methods: The lengths of 15 extracted human teeth were measured with six ALs (Dentaport Root ZX, Dual Pex Micro Mega, Root ZX mini, Elements Diagnostic, Woodpex III, and E-connect S) and with digital radiographs (RVG). Electronic measurements were compared with each other and with radiographic measurements under the same experimental conditions. Results: Repeated measures ANOVA showed a significant difference between the radiographic and the electronic method. The Root ZX achieved the best accuracy and precision in determining the location of the apical foramen compared to other ALs. Conclusions: ALs are the most reliable method and superior to radiologic methods to determine the WL. Further studies should be performed to assess the differences between different types of ALs.
Transit Depth Variations Reveal TOI-216 b to be a Super-puff
Authors: McKee Brendan J. , Montet Benjamin T.
Published: May 2023

The planets of the TOI-216 system have been previously observed to exhibit large transit-timing variations, which enabled precise mass characterization of both transiting planets. In the first year of TESS observations, TOI-216 b exhibited grazing transits, precluding a measurement of its radius. In new observations, we demonstrate the orbit of the planet has precessed and it is now fully transiting, so we can accurately measure its radius. TOI-216 b is a puffy Neptune-mass planet, with a much larger radius that is now well constrained to

⊕ and a density of 0.201 ± 0.017 g cm−3. We numerically integrate the system across the TESS observations to update and refine the masses and orbits of both planets, finding the uncertainty in the masses are now dominated by uncertainties in the stellar parameters. TOI-216 b represents a growing class of super-puff planets in orbital resonances and with a companion in a nearly circular orbit, suggesting the early evolution of these planets is driven by smooth disk migration.
Giant Impacts and Debris Disk Morphology
Authors: Jones Joshua W. , Chiang Eugene , Duchêne Gaspard , Kalas Paul , Esposito Thomas M.
Published: May 2023

Certain debris disks have nonaxisymmetric shapes in scattered light which are unexplained. The appearance of a disk depends on how its constituent Keplerian ellipses are arranged. The more the ellipses align apsidally, the more nonaxisymmetric the disk. Apsidal alignment is automatic for fragments released from a catastrophic collision between solid bodies. We synthesize scattered light images, and thermal emission images, of such giant impact debris. Depending on the viewing geometry, and if and how the initial apsidal alignment is perturbed, the remains of a giant impact can appear in scattered light as a one-sided or two-sided “fork,” a lopsided “needle,” or a set of “double wings.” The last shape is difficult to reproduce in other scenarios involving gravitational forcing or gas drag, which do not align orbits as well. We compare our images with observations and offer a scorecard assessing whether the scattered light asymmetries in HD 15115, HD 32297, HD 61005, HD 111520, HD 106906, β Pic, and AU Mic are best explained by giant impacts, gravitational perturbations, or sculpting by the interstellar medium.
Feedback in the Extremely Violent Group Merger NGC 6338

Published: May 2023

The galaxy group NGC 6338 is one of the most violent group–group mergers known to date. While the central dominant galaxies rush at each other at 1400 km s−1 along the line of sight, with dramatic gas heating and shock fronts detected, the central gas in the BCGs remains cool. There are also indications of feedback from active galactic nuclei, and neither subcluster core has been disrupted. With our deep radio uGMRT data at 383 and 650 MHz, we clearly detect a set of large, old lobes in the southern BCG coinciding with the X-ray cavities, while the northern and smaller BCG appears slightly extended in the radio. The southern BCG also hosts a smaller younger set of lobes perpendicular to the larger lobes, but also coinciding with the inner X-ray cavities and matching the jet direction in the parsec-resolution VLBA image. Our spectral analysis confirms the history of two feedback cycles. The high radio frequency analysis classifies the compact source in the southern BCG with a power law, while ruling out a significant contribution from accretion. The radio lightcurve over three decades shows a change about 10 yr ago, which might be related to ongoing feedback in the core. The southern BCG in the NGC 6338 merger remains another prominent case where the direction of jet-mode feedback between two cycles changed dramatically.
The Welfare Effects of Encouraging Rural–Urban Migration
Authors: Lagakos David , Mobarak Ahmed Mushfiq , Waugh Michael E.
Published: May 2023

This paper studies the welfare effects of encouraging rural–urban migration in the developing world. To do so, we build and analyze a dynamic general‐equilibrium model of migration that features a rich set of migration motives. We estimate the model to replicate the results of a field experiment that subsidized seasonal migration in rural Bangladesh, leading to significant increases in migration and consumption. We show that the welfare gains from migration subsidies come from providing better insurance for vulnerable rural households rather than from correcting spatial misallocation by relaxing credit constraints for those with high productivity in urban areas that are stuck in rural areas.
A Sieve‐SMM Estimator for Dynamic Models
Authors: Forneron Jean-Jacques
Published: May 2023

This paper proposes a Sieve Simulated Method of Moments (Sieve‐SMM) estimator for the parameters and the distribution of the shocks in nonlinear dynamic models where the likelihood and the moments are not tractable. An important concern with SMM, which matches sample with simulated moments, is that a parametric distribution is required. However, economic quantities that depend on this distribution, such as welfare and asset prices, can be sensitive to misspecification. The Sieve‐SMM estimator addresses this issue by flexibly approximating the distribution of the shocks with a Gaussian and tails mixture sieve. The asymptotic framework provides consistency, rate of convergence, and asymptotic normality results, extending existing results to a new framework with more general dynamics and latent variables. An application to asset pricing in a production economy shows a large decline in the estimates of relative risk aversion, highlighting the empirical relevance of misspecification bias.
Financial Frictions and the Wealth Distribution
Authors: Fernández-Villaverde Jesús , Hurtado Samuel , Nuño Galo
Published: May 2023

We postulate a continuous‐time heterogeneous agent model with a financial sector and households to study the nonlinear linkages between aggregate and financial variables. In our model, the interaction between the supply of bonds by the financial sector and the precautionary demand for bonds by households produces significantendogenous aggregate risk. This risk makes the economy transition between a high‐leverage region and a low‐leverage region, which, in turn, creates state dependence in impulse responses: the same shock starting from the high‐leverage region gets propagated and amplified more than when the shock arrives when leverage is low. State dependence in impulse responses generates a time‐varying aggregate precautionary savings motive that, by moving the risk‐free rate, justifies the leverage level of the financial sector in each region. Finally, we illustrate the usefulness of neutral networks to solve for the nonlinear perceived law of motion of the model, and the importance of household heterogeneity in driving its quantitative properties.
Distributional Synthetic Controls
Authors: Gunsilius F. F.
Published: May 2023

The method of synthetic controls is a fundamental tool for evaluating causal effects of policy changes in settings with observational data. In many settings where it is applicable, researchers want to identify causal effects of policy changes on a treated unit at an aggregate level while having access to data at a finer granularity. This article proposes an extension of the synthetic controls estimator that takes advantage of this additional structure and provides nonparametric estimates of the heterogeneity within the aggregate unit. The idea is to replicate the quantile function associated with the treated unit by a weighted average of quantile functions of the control units. This estimator relies on the same mathematical theory as the changes‐in‐changes estimator and can be applied in both repeated cross‐sections and panel data with as little as a single pre‐treatment period. It also provides a unique counterfactual quantile function for any type of distribution.
Pareto‐Improving Tax Reforms and the Earned Income Tax Credit
Authors: Bierbrauer Felix J. , Boyer Pierre C. , Hansen Emanuel
Published: May 2023

We develop a new approach for the identification of Pareto‐improving tax reforms. This approach yields necessary and sufficient conditions for the existence of Pareto‐improving reform directions. A main insight is that “Two brackets are enough”: When the system cannot be improved by altering tax rates in one or two income brackets, then there is no continuous reform direction that is Pareto‐improving. We also show how to check whether a given tax reform is Pareto‐improving. We use these tools to study the introduction of the Earned Income Tax Credit (EITC) in the United States in 1975. A robust finding is that, prior to the EITC, the U.S. tax‐transfer system was not Pareto‐efficient. Under plausible assumptions about behavioral responses, the 1975 reform was not Pareto‐improving. Qualitatively, though, it had the right properties: A similar reform with earnings subsidies made available to a broader range of incomes would have been Pareto‐improving.
Equilibrium Effects of Pay Transparency
Authors: Cullen Zoë B. , Pakzad-Hurson Bobak
Published: May 2023

The discourse around pay transparency has focused on partial equilibrium effects: how workers rectify pay inequities through informed renegotiation. We investigate how employers respond in equilibrium. We study a model of bargaining under two‐sided incomplete information. Our model predicts that transparency reduces the individual bargaining power of workers, leading to lower average wages. A key insight is that employers credibly refuse to pay high wages to any one worker to avoid costly renegotiations with others. When workers have low individual bargaining power, pay transparency has a muted effect. We test our model with an event‐study analysis of U.S. state‐level laws protecting the right of private sector workers to communicate salary information with their coworkers. Consistent with our theoretical predictions, transparency laws empirically lead wages to decline by approximately 2%, and wage declines are smallest in magnitude when workers have low individual bargaining power.
Selection and the distribution of female real hourly wages in the United States
Authors: Fernández-Val Iván , Vuuren Aico , Vella Francis , Peracchi Franco
Published: May 2023

We analyze the role of selection bias in generating changes in the observed distribution of female hourly wages in the United States using CPS data for the years 1975 to 2020. We account for selection bias from the employment decision by modeling the distribution of the number of working hours and estimating a nonseparable model of wages. We decompose changes in the wage distribution into composition, structural, and selection effects. Composition effects increased wages at all quantiles while the impact of the structural effects varied by time period and quantile. Changes in the role of selection only appeared at the lower quantiles of the wage distribution. The evidence suggests that there was positive selection in the 1970s, which diminished until the later 1990s. This reduced wages at lower quantiles and increased wage inequality. Post 2000 there appears to be an increase in positive sorting, which reduced the selection effects on wage inequality.
Managing for agility in constant change: HR strategies for teaching center leaders
Authors: Hoessler Carolyn , Ellis Donna E. , Bayles Bob
Published: May 2023

Centers for teaching and learning (CTLs) exist in dynamic contexts and need to be agile, with skilled, adaptable teams to prepare for and respond to changes. In this article, we provide CTL leaders with relevant and eminently practical strategies from the human resources (HR) literature, offering guidance in the four areas of organizational structure, direction-setting, capacity-building, and accountability. For each area, we address pivotal challenges with practical approaches grounded in existing research and theory to provide options for CTL leaders in their quest to have well-functioning, agile units. Examples focus on helping existing centers to adapt and refocus, as needed, in response to evolving contexts and priorities.

Exacerbation Prevention and Management of Bronchiectasis
Authors: Choi Joon Young
Published: May 2023

Bronchiectasis, which is characterized by irreversibly damaged and dilated bronchi, causes significant symptoms, poor quality of life, and increased economic burden and mortality rates. Despite its increasing prevalence and clinical significance, bronchiectasis was previously regarded as an orphan disease, and ideal treatment of this disease has been poorly understood. The European Respiratory Society and British Thoracic Society have recently published guidelines to assist physicians in the clinical field. Guidelines and reports suggest comprehensive management that includes both non-pharmacological and pharmacological treatment. Physiotherapy and pulmonary rehabilitation are two of the most important non-pharmacologic therapies in bronchiectasis patients; long-term inhaled antibiotics and macrolide therapy have gained significant evidence in reducing exacerbation risk in frequent exacerbators. In this review, we summarize recent updates on bronchiectasis treatment to prevent exacerbation and manage clinical deterioration.

his research focused on studying the variability of solar radiation and temperature under climate change in the Ibadan metropolis. In the study, spatial  distribution, temporal variations, annual distribution, estimation and prediction of the solar radiation, minimum and maximum temperature data in the  Ibadan Metropolis was collected. A Long Short-Term Memory Neural Network (LSTM-NN) model was developed for the prediction using the time-series  data obtained. An ARIMA model was further developed to compare and validate the LSTM-NN model. The performance of the prediction models were  determined using the root mean square error (RMSE) and the mean absolute percentage error (MAPE). The RMSE values for the minimum, maximum  temperature and solar radiation predictions were 1.543, 1.290, 1.967, and 1.611, 1.309, 2.106 for the LSTM-NN and ARIMA models respectively, while the  MAPE values for the minimum, maximum temperature and solar radiation predictions were 3.603, 4.351, 8.859, and 3.840, 4.480, 9.502 for the LSTM-NN  and ARIMA models respectively. The LSTM-NN model had a better prediction performance in all categories with lower error when compared with ARIMA.  From the prediction, it was observed that there will be a reduction in the maximum temperature, minimum temperature and solar radiation values when  compared to obtained data. The observed minimum temperature ranged from 22.9032-23.2032(0C), while the predicted minimum temperature ranged  from 19.9260- 19.977(0C) also the observed maximum temperature ranged from 32.87096-33.7064(0C), while the predicted maximum temperature  ranged from 29.5159-29.5529(0C), the observed solar radiation ranged from 19.203-19.722 (W/m2 ), while the predicted solar radiation ranged from  14.123-14.115 (W/m2 ).

This study aimed to compare the dose distributions of three-dimensional conformal treatment planning using two and six radiation beams among paediatric patients receiving radiotherapy for Wilms tumour at Ocean Road Cancer Institute. CT scans of 53 patients were used to generate 106 treatment plans, 53 plans for two beams, and 53 plans for six beams. Planning target volumes and organs at risk parameters were compared between both plans using paired samples t-test.  A p-value < 0.05 was considered statistically significant. The findings showed that the D95% and Dmean of the target are better with six beams than with the two-beam plans (p ˂ 0.001). The conformity index and monitor unit are significantly better with two-beam plans than with six-beam plans (p ˂ 0.001). No volume of the contralateral kidney received more than 12 Gy for both two and six plans. There were no differences in Dmax for the spinal cord (p = 0.208), while Dmean was observed to be lower in two compared to six beams (p ˂ 0.001) for the liver. Six beam plans have good target coverage, while two beam plans have good conformity index and monitor unit. The observed doses to the organs at risk in both plans were lower than their normal tolerance.

Drilling the wellbore into subsurface formations is the earliest stage in the life of a well that requires a suitable drilling fluid with good rheological and filtration control characteristics to achieve a successful drilling operation. This paper reports on the formulation of water-based drilling mud using kaolin clay reinforced with biopolymer, surfactant, and limestone from Tanzania. The raw materials used for the formulation were characterized using XRD, XRF, FTIR, and TGA techniques. The rheological properties, filtration loss, pH, and density of the formulated mud were measured using a viscometer, filter press, pH meter, and mud balance, respectively. The XRD results revealed kaolinite and quartz as the main minerals in all kaolin clay samples which were in agreement with the FTIR findings. The mineralogical composition of the kaolin was observed to vary with the mining sites and influenced the rheological and filtration control characteristics of the mud. The beneficiated drilling mud showed better rheological and filtration control characteristics than the commercially available bentonite mud in Dar es Salaam market and was comparable with the API standards. These results, therefore, are not only new but rather important and novel information on the potential of kaolin clay for the formulation of water based drilling mud.

Los polifenoles son compuestos que se encuentran en diversas fuentes vegetales, siendo el grupo de los flavonoides el más común de ellos. Dentro de este grupo, las catequinas son de interés en el área cosmética y salud de la piel. Por ello, la investigación se enfocó en la extracción y determinación del contenido de polifenoles, flavonoides y (-)-epicatequinas presentes en cacao proveniente de Canoabo, como potencial agente antienvejecimiento de la piel para ser empleado en la industria cosmética. Se realizó la extracción de los compuestos polifenólicos de la muestra de cacao fermentado y seco empleando un equipo Soxhlet, usando como solvente metanol. La caracterizacion se llevó a cabo por espectroscopia infrarroja (FTIR), espectroscopia UV-visible, cromatografía líquida de alta eficiencia (HPLC), microscopia electrónica de barrido (SEM) y tensiómetro de Du Nouy. Empleando FTIR y UV-Visible, se determinó la presencia de flavonoides. El extracto alcohólico del cacao presentó una concentración de polifenoles totales igual a 13.500,56 ± 0,89 mg AG/L y la concentración de flavonoides igual a 7.792,2 ± 0,3 mg EC/L. A través del HPLC se determinó que la cantidad de (-)- epicatequina resultó 1.434,4 ± 0,6 mg EC/kg. A través de la determinación de la tensión superficial a una solución acuosa al 1 % v/v de extracto polifenólico, se evidenció que los polifenoles pueden comportarse como anfífilos. Con los resultados obtenidos se puede garantizar que el extracto contiene los polifenoles necesarios para ser incorporados en una formulación con potencial aplicación cosmética.

Published: May 2023

The purpose of the article is to identify the positive experience of Slovakia in the field of legal liability of medical workers, which has been successful in practice and therefore worth following, both in Ukraine and in other states. To achieve this purpose, general and special scientific research methods were used, in particular dialectical, historical-legal, systematic, and comparative legal methods. The legal regulation of liability for the provision of medical services constantly generates debate in scientific circles and in practical implementation. The legislation of Ukraine does not regulate concepts such as medical mistakes and medical crimes. The lack of regulatory criteria for medical mistakes and crimes, the difficulty in determining the cause and effect relationship, as well as the need for professional supervision in the provision of medical services, encourages the study of foreign experience, mainly the experience of the European Union Member States in this field.
