The 1985 Emergency Stabilizing Plan: A Reexamination
Authors: Krampf Arie ,   Avi Bareli and Ofer Shiff
Published: July 2024

The Emergency Stabilization Plan is recognized as a turning point in the economic history of Israel. It transformed Israel from an economy characterized by extensive state intervention to a market economy, in which the private sector is much more dominant. Although there is an extensive literature on the long-term impact of the plan, historical research on the plan itself—its formation, implementation, and immediate consequences—is limited. Moreover, the existing research focuses on the domestic factors that allegedly caused the crisis. In this article, I reopen the ‘black box’ of the Stabilization Plan to identify the international factors that contributed to the economic crisis, with the goal of tracing the evolution of the Plan and its implementation based on archival research and reevaluating its successes and failures. The article makes three key arguments: First, I argue that the economic crisis of the 1980s was fundamentally a debt crisis, which was caused by international factors, in contrast to existing research which underlines the role of inflation, which was allegedly caused by the government's careless fiscal policy. Second, I argue that the Stabilization Plan proposed by Michael Bruno and approved by the government was based on neo-mercantilist principles that were designed to address Israel's trade balance deficit and external debt. The policy was grounded on the logic of internal devaluation, according to which the lowering of real wages will encourage Israeli exports and improve the competitiveness of the Israeli economy. This claim challenges the existing literature which emphasizes the neoliberal components of the Plan and the reduction of state involvement in the economy. Thirdly, I argue that the Plan proposed by Bruno and approved by the government in fact failed to achieve two of its declared objectives: lower inflation and an improvement in the balance of payments. It failed due to the very effective protests by workers and the Histadrut (the national labor union) against the government’s intention to freeze wages. I further argue that the policy instrument that eventually stabilized prices was an interest rate hike initiated by the Bank of Israel, with the support of the Minister of Finance. I argue that the involvement of the Bank of Israel was not part of Bruno’s original plan. Although the Bank’s policy led to a reduction of inflation, it did not achieve the Plan’s other objective, that is, to improve Israel’s balance of payments. Based on this interpretation, it appears that the Stabilization Plan was not an ideological transformation from a collectivist ideology to a liberal one, but rather a modification of Israel’s collectivist spirit to better suit the globalized era.
The Bourgeois Home in Young Israel from a Global Perspective
Authors: Heilbronner Oded
Published: July 2024

Israeli critical research tends to view the Israeli home in the 1950s and 1960s as an institutional tool for shaping society. However, the central focus of individuals on the modern home, its design, and its furnishing during the second decade of the state's existence is evidence of its dominant position and its cultural, emotional, and ethical importance among the emerging Israeli bourgeoisie. As in Western European countries following World War II, the modern Israeli home expressed a desire to disconnect from a violent, crisis-filled and painful past and to build a new, modernist and, most importantly, stable future. Alongside government authorities and planning bodies, citizens, tenants, and families took advantage of design books and the guidance and advice provided by interior designers, architects, and self-proclaimed household management experts in order to participate in the design of the home. The building, the house and the apartment were also designed according to the family's requirements and its character, thus expressing the values of the Israeli bourgeoisie and its desire to integrate within consumer culture. The modern Israeli home became an emotional fortress, a protected refuge for middle-class Israelis against strangers and dangers.
The Preference for Locals in Land Allocations for Housing in Various Settlement Types in Israel
Authors: Margalit Avital , Stern Shai
Published: July 2024

The question of who has the right to reside in a particular locality has been at the center of public and legal discourse in Israel for many years. This is the result of official and unofficial mechanisms intended to exclude certain individuals or groups. This article deals with a related though different issue, which focuses on the preference given to locals during the allocation of state land. Addressing this question requires a discussion of issues such as individual freedom, the meaning of home, the importance of family, the significance of residency in a particular place, the nature of various types of settlements in Israel, justice in land distribution and the necessity of correcting of historical wrongs versus the perpetuation of existing social stratification, as well as the preservation of existing communities versus concerns about pushing them out of a neighborhood or settlement. After presenting a framework for thinking about the issue of preference of locals, the article conducts a critical examination of the existing legal framework in Israel in both rural areas, where the right of residency is managed by cooperative associations, and urban areas, which include, for this purpose, the settlements of minorities. The conclusion drawn from this analysis is that the same flaws in legal decision making with respect to acceptance by a settlement also exist in the regulation of the preference for locals. The social and economic outcomes that affect the lives of individuals and the distribution of land in Israel perpetuate established ways of thinking about forms of residency and about disparities and social differentiation in Israel.
Social Welfare Activity in the Jewish Community in Jerusalem during the Mandate Period
Authors: Chenya Tal
Published: July 2024

In this article, I analyze the factors that shaped social welfare activity in the Jewish community in Jerusalem during the British Mandate in Palestine. First, I review the attitude towards social welfare activity in the City Council—the body that preceded the Community Council—during the 1920s. Second, I examine the activities and efforts of the Social Welfare Bureau by way of the Community Council in the early 1930s. Third, I analyze on two levels the impact of political events in the Jewish Yishuv from the mid-1930s until late in the Mandate period on social welfare activities: on the municipal level, with emphasis on the impact of Jerusalem’s unique factors and characteristics, including the Sephardic Community Council’s political influence on community-social welfare activities; and at the national level of the Jewish Yishuv, which included the influence of the Fifth Aliyah and the Yishuv fundraising organizations on the activities of the Social Welfare Bureau in the 1940s. Based on the analysis of each of the aforementioned players, I propose that the nature and scope of social welfare activities in Jerusalem were the result of three combined influences: the Jewish Yishuv – initiatives originating from the National Institutions; the community influence – activities based on the Community Council’s status and a community-oriented outlook; and the local influence – norms and attitudes that were prevalent in Jerusalem before the British conquest. Therefore, I show in this article that the Jewish Yishuv framework is one of the components that shaped social welfare activity in Jerusalem.

O panorama das práticas contabilísticas sofreu transformações significativas na sequência das iniciativas de reforma tributária. À medida que as leis e regulamentos fiscais continuam a evoluir, as metodologias contabilísticas tiveram de se adaptar para garantir a conformidade e a transparência. Este trabalho aprofundará o impacto da reforma tributária nas práticas contábeis, os avanços tecnológicos que revolucionaram o campo e os desafios e oportunidades que surgiram neste ambiente dinâmico. O impacto da reforma tributária nas práticas contabilísticas tem sido profundo, com alterações nas leis e regulamentos fiscais que exigem ajustamentos nos métodos contabilísticos. As empresas tiveram de reavaliar as suas estratégias de relato financeiro para refletirem com precisão as implicações fiscais destas reformas. Por exemplo, a redução das taxas de imposto sobre as sociedades ao abrigo da Lei de redução de impostos e empregos levou as empresas a reavaliarem os seus ativos e passivos por impostos diferidos. Esta mudança exigiu um alinhamento mais estreito entre o planeamento fiscal e os relatórios financeiros para garantir divulgações precisas e transparentes. Além disso, a complexidade destas novas leis fiscais levou a uma maior ênfase no cumprimento fiscal e à necessidade de controlos internos robustos para mitigar os riscos de incumprimento.

Transferability of machine-learning-based global calibration models for NO2 and NO low-cost sensors
Authors: Abu-Hani Ayah , Chen Jia , Balamurugan Vigneshkumar , Wenzel Adrian , Bigi Alessandro
Published: July 2024

Abstract. It is essential to accurately assess and verify the effects of air pollution on human health and the environment in order to develop effective mitigation strategies. More accurate analysis of air pollution can be achieved by utilizing a higher-density sensor network. In recent studies, the implementation of low-cost sensors has demonstrated their capability to quantify air pollution at a high spatial resolution, alleviating the problem of coarse spatial measurements associated with conventional monitoring stations. However, the reliability of such sensors is in question due to concerns about the quality and accuracy of their data. In response to these concerns, active research efforts have focused on leveraging machine learning (ML) techniques in the calibration process of low-cost sensors. These efforts demonstrate promising results for automatic calibration, which would significantly reduce the efforts and costs of traditional calibration methods and boost the low-cost sensors' performance. As a contribution to this promising research field, this study aims to investigate the calibration transferability between identical low-cost sensor units (SUs) for NO2 and NO using ML-based global models. Global models would further reduce calibration efforts and costs by eliminating the need for individual calibrations, especially when utilizing networks of tens or hundreds of low-cost sensors. This study employed a dataset acquired from four SUs that were located across three distinct locations within Switzerland. We also propose utilizing O3 measurements obtained from available nearby reference stations to address the cross-sensitivity effect. This strategy aims to enhance model accuracy as most electrochemical NO2 and NO sensors are extremely cross-sensitive to O3. The results of this study show excellent calibration transferability between SUs located at the same site (Case A), with the average model performance being R2 = 0.90 ± 0.05 and root mean square error (RMSE) = 3.4 ± 0.9 ppb for NO2 and R2 = 0.97 ± 0.02 and RMSE = 3.1 ± 0.8 ppb for NO. There is also relatively good transferability between SUs deployed at different sites (Case B), with the average performance being R2 = 0.65 ± 0.08 and RMSE = 5.5 ± 0.4 ppb for NO2 and R2 = 0.82 ± 0.05 and RMSE = 5.8 ± 0.8 ppb for NO. Interestingly, the results illustrate a substantial improvement in the calibration models when integrating O3 measurements, which is more pronounced when SUs are situated in regions characterized by elevated O3 concentrations. Although the findings of this study are based on a specific type of sensor and sensor model, the methodology is flexible and can be applied to other low-cost sensors with different target pollutants and sensing technologies. Furthermore, this study highlights the significance of leveraging publicly available data sources to promote the reliability of low-cost air quality sensors.

Published: July 2024

Abstract. Accurate and continuous estimates of the thermodynamic structure of the lower atmosphere are highly beneficial to meteorological process understanding and its applications, such as weather forecasting. In this study, the Tropospheric Remotely Observed Profiling via Optimal Estimation (TROPoe) physical retrieval is used to retrieve temperature and humidity profiles from various combinations of input data collected by passive and active remote sensing instruments, in situ surface platforms, and numerical weather prediction models. Among the employed instruments are microwave radiometers (MWRs), infrared spectrometers (IRSs), radio acoustic sounding systems (RASSs), ceilometers, and surface sensors. TROPoe uses brightness temperatures and/or radiances from MWRs and IRSs, as well as other observational inputs (virtual temperature from the RASS, cloud-base height from the ceilometer, pressure, temperature, and humidity from the surface sensors) in a physical iterative retrieval approach. This starts from a climatologically reasonable profile of temperature and water vapor, with the radiative transfer model iteratively adjusting the assumed temperature and humidity profiles until the derived brightness temperatures and radiances match those observed by the MWR and/or IRS instruments within a specified uncertainty, as well as within the uncertainties of the other observations, if used as input. In this study, due to the uniqueness of the dataset that includes all the abovementioned sensors, TROPoe is tested with different observational input combinations, some of which also include information higher than 4 km above ground level (a.g.l.) from the operational Rapid Refresh numerical weather prediction model. These temperature and humidity retrievals are assessed against independent collocated radiosonde profiles under non-cloudy conditions to assess the sensitivity of the TROPoe retrievals to different input combinations.
H2 mobility and redox control in open vs. closed hydrothermal oceanic systems – evidence from serpentinization experiments
Authors: Fauguerolles Colin , Castelain Teddy , Villeneuve Johan , Pichavant Michel
Published: July 2024

Abstract. New hydrothermal experiments in rapid-quench pressure vessels have been performed to investigate the effect of redox state on the serpentinization reaction. The experimental hydrogen fugacity (fH2) was controlled by monitoring the mobility of H2 in the reacting system (internal vs. external fH2 control). This was achieved by using either Au (H2 impermeable) or AgPd (H2 permeable) capsules and Ar pressurizing gas to control fH2. The experiments were performed with either San Carlos olivine powders or Åheim dunite chips. Water / rock mass ratios of 1–2, a total pressure of 50 MPa, and temperatures of 300 and 350 °C were investigated. Experimental durations of 30, 45, or ≈80 d were imposed. Serpentine production is observed in almost all experiments but is favored at 300 °C under external fH2 control. The serpentine–magnetite assemblage is observed in Au capsules (high fH2) at 300 °C, while the serpentine–hematite(–magnetite) is observed in AgPd capsules (low fH2). At 350 °C, less H2 is produced than at 300 °C and the serpentine–hematite(–magnetite) assemblage is present in both Au and AgPd capsules. Brucite is absent and this is interpreted to reflect both the initially oxidizing conditions and relatively low serpentine production in our experiments. Differences in product phase assemblages found in this study imply that natural serpentinization reaction mechanisms vary with redox conditions, and consequences for H2 production fluxes and rates can be expected. The high-fH2 (reduced) internally controlled experiments simulate low-permeability “closed” oceanic hydrothermal systems. The low-fH2 (oxidized) externally controlled experiments are analogous to “open” oceanic hydrothermal systems where serpentinization is driven by tectonically aided infiltration of an external fluid.

Jovian Trojan and Hilda asteroids are of particular importance because they provide important constraints for Solar System formation and evolution models. Despite their large number, rotational characteristics are known for a relatively limited sample from ground-based observations. Rotation period and amplitude distributions derived from this sample are strongly affected by ground-based biases, as it was shown by recent studies using data from the K2 mission of the Kepler Space Telescope. An important result of these investigations is that there are a significantly larger number of slow rotators than previously thought. Here we present several week-long, uninterrupted light curves, in many cases spanning over multiple sectors for a large number of Jovian Trojans and Hildas, provided by the TESS mission. Our results are compared with the previous investigations of ground-based observations and K2 measurements, confirming the significance and the presence of slow rotators as it was hinted by earlier studies. We also investigate the difference between the rotational characteristics of the 'red' and 'less red' groups and that of the different collisional families. Figure 1.:Cleaned light curve, frequency spectrum and folded light curve of the Hilda asteroids (153) Hilda and (197558) 2004 FL122, observed by TESS.
Surface geological evolution in the Chang’e 5 landing area (Em4 unit) revealed by a new age-retrieving method from regression learning
Authors: Chen Yuchao , Huang Qian
Published: July 2024

The chronology function and production function have been widely used to derive the model ages of lunar mare regions from crater size-frequency distributions (CSFDs). Challenges remain in homogenous counting area selection, crater saturation and crater rim identification. Geological unit-based ages are also difficult to study the continuous surface evolution among adjacent areas. Using regression-learning models, we have tried a new method on the Em4 unit of the Chang’e 5 landing area to explore a quantitative relationship between ages and surface morphometric expressions by using texture features. Four features (Contrast, Energy, Entropy and Homogeneity), together with a stepwise linear model (SL) and a linear support-vector-machine model (LS) are well selected to produce a pixel-level continuous age map of the Em4 unit. Mean age values of 1.75 ±0.26 Ga and 1.69 ±0.22 Ga obtained respectively from the two models are consistent with the ages of Chang’e 5 samples returned from this area. Both texture features and age maps are separated along the NW-SE sinuous rilles (Rima Sharp and Rima Mairan). Comprehensively considering geology, geomorphology, and newly retrieved ages of the study region, we have proposed a three-stage evolution process for the Em4 unit. Our new age-retrieving method is useful to obtain a pixel-level high-resolution age map in the study region and has the potential to be widely used in other lunar mare areas. 
D Modeling of the Magma Ocean Stage of Rocky Planets 
Authors: Wu Meiye , Noack Lena
Published: July 2024

To better understand the evolution of rocky planet interiors and their redox transformations, we are developing a comprehensive 1D mineralogical and geochemical interior model. This model is designed to simulate the initial conditions and subsequent evolution of rocky planet interiors in the magma ocean stage.
This project creates a 1D grid-based compressible interior-structure model with a magma ocean thermal evolution and solidification model, building upon existing codes and models [1]. Differing from previous magma ocean models, this 1D model incorporates the evolution of core differentiation and couples it with a magma ocean model. We also further enhance previous models by incorporating depth-dependent thermodynamic properties and implementing high-temperature and high-pressure melt Equations of State (EOS). We are developing a composition-dependent melting temperature formulation that aligns with low-pressure melting temperature laws. For the high-pressure environments of planetary interiors, we apply the extended Lindemann-Stacy melting law [2]. Moreover, the early planet accretion stage is considered in this model and different accretion scenarios are investigated.
Our approach is expected to provide thermal and chemical profiles from planet formation till the end of the magma ocean stage. Our results will help determine the efficiency of core formation under different redox states and planetary conditions during the magma ocean stage. In the future, the results of this model could also be used as inputs for 2D convection simulations or planetary atmospheric models.

In this contribution we give an overview of the first results ofcosmic dust phenomena in this extraordinary environment, but also on the technical aspects of the model.The Saturn Dust model traces test particles from source tosink, ejected in the plumes of Enceladus feeding the E ring, and from impact ejecta processesgenerating a low number of particles from other airless bodies. Their trajectories arenumerically integrated taking into account all relevant forces and mechanisms, i.e. gravity,radiation pressure, Lorentz force, plasma drag, electric charging, and sputtering. We discuss the calibration using existing observations, based predominantly on results from the Cassini mission, we present an overview of the dynamical phenomena associated with dust in this environment, and we give an outlook on the upcoming user interfacefor the model as a tool for mission planning and risk estimation.

Introduction: Dark mantle deposits (DMDs) are one of the lunar lithological units commonly composed of mafic minerals mixed with pyroclasts [1,2]. Lunar pyroclasts in the form of partially crystallized Fe-Ti bearing volcanic glasses provide records of the early history of lunar volcanism [3]. DMDs of diverse nature in terms of their mineralogy and physical characteristics indicate complex nature of lunar explosive volcanism which is not yet fully understood. This study focuses on regional (>1000 km2) pyroclastic deposits around Sinus Aestuum (12.1˚ N, 8.3˚ W) and Aristarchus (23.7˚ N, 47.5˚ W) regions and local deposits (
Advancing Exoplanet Transit Characterization through Machine Learning

In this study, we go beyond the usage of a single modeling approach and employ a range of scalable ML models, including Random Forest (RF), Decision Tree (DT), K-Nearest Neighbors (KNN), and Gradient Boosting (GB). However, to comprehensively evaluate the performance of these ML models, we compare their results with those obtained from the ExoRotGP model. By comparing the outcomes of these ML models with the reference GP results, we aim to rigorously assess their respective abilities in accurately extracting transit and rotation parameters from Kepler light curves. Specifically, we emphasize determining the rotation period of the host star for a given exoplanet. Through this meticulous comparative analysis, we seek to gain valuable insights into the strengths and limitations of different modeling approaches, thereby contributing to the advancement of exoplanet characterization techniques. This approach allows us to explore the diverse perspectives and potential synergies between the ML models and the ExoRotGP model, leading to a more comprehensive understanding of the underlying data and enhancing our ability to uncover important insights from exoplanetary systems.

The MErcury Radiometer and Thermal infrared Imaging Spectrometer (MERTIS) is part of the payload of the Mercury Planetary Orbiter spacecraft of the ESA-JAXA BepiColombo mission. MERTIS combines an imaging spectrometer covering the wavelength range of 7-14 μm with a radiometer covering the wavelength range of 7-40 μm. The instrument will map the whole surface of Mercury with a spatial resolution of 500 m for the spectrometer channel and 2 km for the radiometer channel. The compositional map of Mercury provided by MERTIS will allow unique insights into the evolution of the least explored terrestrial planet and will directly address questions raised by the NASA MESSENGER mission. For example, MERTIS will be able to provide spatially resolved compositional information on the hollows and pyroclastic deposits and answer the question whether hollows are actually predominately composed of sulfide. MERTIS will also provide spatially resolved temperature maps inside the permanently shadowed craters, thereby potentially constraining the stability of water ice deposits in those craters.BepiColombo is currently in the final part of its 7-year journey to Mercury. The interplanetary cruise includes in total nine flybys for gravitational assists: one at Earth, two at Venus and six at Mercury. MERTIS could obtain so far observations during the Earth flyby in April 2020, the first Venus flyby (FB1) in October 2020 and the second Venus flyby (FB2) on August 10, 2021. The recently published results for FB2 show that MERTIS performed well beyond requirements and provided new insights into the long-term stability of the Venusian atmosphere.

Data assimilation of the Venus atmosphere has become more feasible due to the long-term observations by the Venus climate orbiter “Akatsuki”. We have produced the first objective analysis for the Venus atmosphere by assimilating horizontal winds derived by the cloud tracking of the Akatsuki Ultraviolet Imager (UVI) [1]. Here, we assimilate the temperature derived by the Akatsuki Longwave Infrared Camera (LIR), using the AFES-LETKF data assimilation system for Venus "ALEDAS-V" [2], which is based on the atmospheric general circulation model for Venus "AFES-Venus" [3] and local ensemble transform Kalman filter “LETKF”. In this experiment the altitude for the assimilation is set to 65 km regardless of the emission angle for simplicity, though the altitude observed by LIR depends on the emission angle (the angle between the zenith and observer directions as seen from the observation point). The influence of the emission angle is investigated for two cases; the one is the emission angle limited to 40 degrees or less and the other one is that limited to 75 degrees or less. [1] Fujisawa, Y., Sy.

This contribution focuses on the PEPSO (Plasma Environment Platform for Satellite tests in Orléans) plasma chamber facility, hosted at the LPC2E Laboratory in Orléans, France, since 2020, as well as specific examples of how it is being used for the design of planetary and cometary space plasma experiments. PEPSO is designed to provide a test environment that mimics the plasma environment in terrestrial, planetary or cometary ionospheric regions. It is composed of a 1.8m long and 1m wide cylindrical vacuum chamber, a pumping system, a plasma source, and a flexible set of sensors. The vacuum chamber has a form factor that is compatible with the study of the behavior of objects of limited size, such as nanosatellites, payload or specific sensors. The pumping system creates the conditions for the use of the plasma source. The plasma source ensures the creation of a plasma with characteristics similar to Earth ionospheric plasma. Various diagnostics are used to monitor the plasma characteristics and therefore provide feedback on the current state of the plasma. PEPSO has been recently used to perform mutual impedance experiments. Mutual impedance instruments are an active, in situ space plasma diagnostic dedicated to the measurements of electrons. They rely on two electric antennas, one of them is used to generate an electric perturbation inside the plasma, while the other one measures such perturbation. The propagation characteristics of the perturbation provides insight into the plasma properties. They are part of the scientific payload of past, current, and future space missions. Such missions include the joint ESA/JAXA BepiColombo, that targets Mercury, the ESA JUICE, that targets Jupiter and its moons, the ESA Comet Interceptor, that targets a pristine comet, and the M-MATISSE mission project that targets space weather studies at Mars.In our contribution, we will illustrate how the PEPSO facility has been used, e.g., for the design of the COMPLIMENT (COMetary Plasma Light InstruMENT) of the ESA Comet Interceptor mission, for the design of the COMPASS/MIX experiment for the M-MATISSE mission project, as well as to support the CNES-funded COMIX (COmpact Mutual Impedance eXperiment) R&T project. In particular, we will focus on the development of new instrumental techniques that improve the mutual impedance time resolution up to a factor 20. We will show how numerical models of the instrument are tested in the controlled environment of a laboratory experiment by comparing their predictions to the measurements. This enables the use of such numerical models to obtain a plasma diagnostic from embarked instrument.
