Promoter’s Shareholding, Financial Distress and Capital Structure Decisions: An Empirical Study of Indian Firms
Authors: Tiwari Harendra Nath 
Published: February 2024

This paper examines the effect of promoter’s shareholding and the level of financial distress on capital structure of Indian firms. Using the annual financial data of 1,102 non-financial firms listed on the Bombay Stock Exchange (BSE) from 2007 to 2019 in a panel structure, our study employs dynamic panel data techniques for analysis. The main objective of this paper is to find out how the financially distressed Indian firms choose debt in their capital structure and the role of promoter’s shareholding in such choices. For this purpose, four groups of companies have been formed by combining various degrees of promoter’s shareholding and the level of financial distress measured through Altman’s Z-Score. Dummy variables were introduced to represent each group in the model. This paper uses industry leverage, net working capital to total assets ratio, growth opportunities (Market to book ratio), profitability, tangibility and size as the control variables in the final empirical model.
The findings provide that financially distressed Indian firms maintain higher leverage ratio than a financially non-distressed firm irrespective of the degree of ownership concentration in the hands of promoters. Since majority of Indian firms are owned by business families, this finding is completely opposite to the risk aversion behaviour of family- owned firms as advocated in literature.

Entre “remembranças”, goles e sonhos: tateando fissuras destes tempos
Authors: Cerqueira Gama Bruno , Santos do Nascimento Cruz Edileuza 
Published: February 2024

A partir de rupturas que a pandemia de Covid-19 produziu em nosso cotidiano, este texto busca pensar a dimensão ético-política de olhar e transitar por trechos de fissuras da vida, pelos modos como produzimos questões e respostas para o que vivemos. Algumas imagens atravessadas pelo ser gente-aprendente-profissional na universidade se fizeram narrativas, trazendo “questões-nós” e tentativas de trânsitos por suas fissuras. Ensaiar respostas que sustentem vivas as questões se mostra como condição fundamental para a manutenção do caráter inventivo da vida face ao imperativo utilitarista-produtivista-consumista vigente.

Abstract. This study describes a high-performance single-particle mass spectrometry (HP-SPAMS) design in detail. The comprehensive improvements in the injection system, optical sizing system, mass spectrometry, and data acquisition system have improved particle detection efficiency and chemical analysis. The combination of an aerodynamic particle concentrator (APC) system and a wide range of aerodynamic lenses (ADLs) enables the concentration of particles in the 100–5000 nm range. Using an APC increases the instrument inlet flow by a factor of 3–5. The ion delayed-exaction technology of bipolar time-of-flight mass spectrometry improves the mass resolution by 2–3 times, allowing the differentiation of isobaric ions of different substances. Moreover, the four-channel data acquisition technology greatly enhances the dynamic range of mass spectrometry. The improved HP-SPAMS enhances the overall capability of the instrument in terms of particle detection number and scattering efficiency. Moreover, it improves accuracy and sensitivity for component identification of individual particles. The experimental performance of HP-SPAMS shows that the scattering efficiency of polystyrene latex microspheres is almost 70 %–100 % in the range of 300–3000 nm. Compared to the previous SPAMS, HP-SPAMS has a larger inlet flow rate and scattering efficiency and a higher laser frequency, which makes HP-SPAMS increase the effective number of particles detected and improve the temporal resolution of detection. For the analysis of individual particles, HP-SPAMS achieves an average mass spectral resolution of 2500 at m/z 208, which helps distinguish between most organic fragment ions and metal ions and facilitates the analysis of complex aerosol particles. For the analysis of individual particles, the increased resolution of the HP-SPAMS contributes to the differentiation of most organic fragment ions and metal ions and facilitates the evaluation of complex aerosol particles, in the case of atmospheric lead-containing particles. The improved detection efficiency and chemical analysis capability of HP-SPAMS will be of great importance for low-concentration aerosol detection and complex aerosol component analysis.

Abstract. Large sample datasets are transforming the catchment sciences, but there are few off-the-shelf stream water chemistry datasets with complementary atmospheric deposition, streamflow, meteorology, and catchment physiographic attributes. The existing CAMELS (Catchment Attributes and Meteorology for Large-sample Studies) dataset includes data on topography, climate, streamflow, land cover, soil, and geology across the continental US. With CAMELS-Chem, we pair these existing attribute data for 516 catchments with atmospheric deposition data from the National Atmospheric Deposition Program and water chemistry and instantaneous discharge data from the US Geological Survey over the period from 1980 through 2018 in a relational database and corresponding dataset. The data include 18 common stream water chemistry constituents: Al, Ca, Cl, dissolved organic carbon, total organic carbon, HCO3, K, Mg, Na, total dissolved N, total organic N, NO3, dissolved oxygen, pH (field and lab), Si, SO4, and water temperature. Annual deposition loads and concentrations include hydrogen, NH4, NO3, total inorganic N, Cl, SO4, Ca, K, Mg, and Na. We demonstrate that CAMELS-Chem water chemistry data are sampled effectively across climates, seasons, and discharges for trend analysis and highlight the coincident sampling of stream constituents for process-based understanding. To motivate their use by the larger scientific community across a variety of disciplines, we show examples of how these publicly available datasets can be applied to trend detection and attribution, biogeochemical process understanding, and new hypothesis generation via data-driven techniques.

Published: February 2024

Abstract. Debris flows triggered by rainfall are catastrophic geohazards that occur compounded during extreme events. Few early warning systems for shallow landslides and debris flows at the territorial scale use thresholds of rainfall intensity–duration (ID). ID thresholds are mostly defined using hourly rainfall. Due to instrumental and operational challenges, current early warning systems have difficulty forecasting sub-daily time series of weather for landslides in the Himalayas. Here, we present a framework that employs a spatio-temporal numerical model preceded by the Weather Research And Forecast (WRF) Model for analysing debris flows induced by rainfall. The WRF model runs at 1.8 km × 1.8 km resolution to produce hourly rainfall. The hourly rainfall is then used as an input boundary condition in the spatio-temporal numerical model for debris flows. The debris flow model is an updated version of Van Asch et al. (2014) in which sensitivity to volumetric water content, moisture-content-dependent hydraulic conductivity, and seepage routines are introduced within the governing equations. The spatio-temporal numerical model of debris flows is first calibrated for the mass movements in the Kedarnath catchment that occurred during the 2013 North India floods. Various precipitation intensities based on the glossary of the India Meteorological Department (IMD) are set, and parametric numerical simulations are run identifying ID thresholds of debris flows. Our findings suggest that the WRF model combined with the debris flow numerical model shall be used to establish ID thresholds in territorial landslide early warning systems (Te-LEWSs).
An experimental study on the aerodynamic loads of a floating offshore wind turbine under imposed motions
Authors: Taruffi Federico , Novais Felipe , Viré Axelle 
Published: February 2024

Abstract. The rotor of a floating wind turbine is subject to complex aerodynamics due to changes in relative wind speeds at the blades and potential local interactions between blade sections and the rotor near wake. These complex interactions are not yet fully understood. Lab-scale experiments are highly relevant for capturing these phenomena and provide means for the validation of numerical design tools. This paper presents a new wind tunnel experimental setup able to study the aerodynamic response of a wind turbine rotor when subjected to prescribed motions. The present study uses a 1:148 scale model of the DTU 10 MW reference wind turbine mounted on top of a 6 degrees of freedom parallel kinematic robotic platform. Firstly, the thrust variation of the turbine is investigated when single degree of freedom harmonic motions are imposed by the platform, with surge, pitch and yaw being considered in this study. For reduced frequencies greater than 1.2, it is found that the thrust variation is amplified by up to 150 % compared to the quasi-steady value when the turbine is subject to pitch and surge motions, regardless of the amplitude of motion. A similar behaviour is also noticed under yaw motions. Secondly, realistic 6 degrees of freedom motions are imposed by the platform. The motions are derived from FAST simulations performed on the full-scale turbine coupled with the TripleSpar floater, and the tests aim at exploring the thrust force dynamics for different sea states and wind conditions, obtaining reasonable agreement with the simulations. Finally, the work shows the capabilities of an off-the-shelf hexapod to conduct hybrid testing of floating offshore wind turbines in wind tunnels, as well as its limitations in performing such tests.

«Unearthing the divine horrors»
Authors: Restelli Francesca 
Published: February 2024

This study looks into H. P. Lovecraft’s masterful craft of cosmic horror, examining his adept fusion of Christian cosmological elements with subversion and mockery, while concurrently forging a unique cosmic framework. Lovecraft subtly weaves Christian themes into his mythos, introducing his eldritch terrors, deities reminiscent of Christian demonology. These entities, residing in abyssal depths, bear distinctly demonic attributes, highlighting the profound influence of Christian cosmology. The enigmatic entity Dagon, rooted in biblical mythology, is a focal point. Its appearances correlate with catastrophic consequences and the underworld, subverting Christian narratives and invoking a sense of dread through an alternative lens. Lovecraft strategically manipulates Christian celebrations, such as May-Eve and All-Hallows, challenging their significance and intensifying readers’ religious discomfort. Lovecraft’s cosmic framework is non-anthropocentric, portraying an indifferent universe inhabited by ancient cosmic entities beyond human comprehension. However, he alludes to an impending chaos, drawing subtle parallels with the biblical Apocalypse. Lovecraft’s narratives interweave Christian cosmology, subversion, and mockery, challenging religious frameworks while invoking terror and fascination, providing a rich tapestry for scholarly analysis in cosmic horror literature.

“It’s complicated…” Social Media and Polish Law Enforcement Agencies’ Relationship
Social media has become an integral part of our social fabric; it is also utilized by law enforcement as both a crime scene under investigation and a tool for investigating offline crimes, often providing valuable evidence. However, there are gaps in our understanding of global social media use, as research has focused primarily on English-speaking countries. This article presents a survey on how Polish police officers and prosecutors use social media in their daily practices. The survey utilized the computer-assisted personal interviews (CAPI) technique to explore the reality of Polish law enforcement. Respondents, consisting of police officers and prosecutors (n = 67 + 116), answered questions about their official and private use of social media. The study aimed to test hypotheses related to age and the official and private use of social media. The results of the survey contradict some expectations. Police officers and prosecutors use social media more frequently than their civilian counterparts. They are often reactive to the actions of criminals, which fits the arms race theory. However, some law enforcement officials have proactive strategies, and their knowledge and skills are exceptional.

In Ecuador, in 2020, there were 38,2 cases per 100 000 inhabitants, with a mortality rate of 10,9 per 100 000 individuals, emphasizing the importance of early detection and access to effective treatments to reduce the morbimortality associated with this pathology.Methodology: astematic review of 58 922 scientific articles was conducted, from which, applying inclusion and exclusion criteria, 36 publications were selected from databases such as PubMed, BVS, SCOPE, Web of Science, Google Scholar, and health websites of the six representative countries under study: the United States, Canada, Mexico, Uruguay, Brazil, and Ecuador. The collected data measured the impact and characteristics of breast cancer detection programs in relation to the reduction of mortality.Results: fifty percent of selected countries have active breast cancer detection programs, 33 % (equivalent to 2 nations) had protocols and clinical guidelines for prevention, and only one South American country was in the initial stage of implementing a sustainable pilot plan.Conclusion: in the Americas Region, it is crucial for governments to implement organized and accessible programs, ensuring universal access to the diagnosis and treatment of breast cancer. Ecuador must join this initiative, promoting prevention and public health through pragmatic policies to reduce mortality from breast cancer
What Are We Learning from Impact Evaluation Studies about Teacher Incentives and Education Quality
Authors: Chi Jin , Velez Bustillo Eduardo 
Published: February 2024

The quality of teachers is a determinant to the quality of the education system. Despite the significant increase in resources invested in teacher incentives, there is little robust empirical evidence on their effectiveness, especially showing attribution. This paper examines the international literature using Impact Evaluation (IE) studies to see what lessons can be learned, focusing specifically on a key education input: teacher incentives as a policy to motivate teachers and improve education quality in middle- and low-income developing countries. The review shows there are limited number of IE studies on teacher incentives at the preschool, primary and secondary education levels applying robust experimental design and the results are mixed. When incentives are used properly they can have a positive impact on the quality of education. However, certification itself is not enough as a way to improve the quality of the education system; it is critical to develop reforms explicitly geared towards quality. Finally, although incentives can reduce teacher absenteeism, they do not always improve the quality of education outcomes.
