PURPOSE Access to radiotherapy (RT) is now one of the stark examples of global cancer inequities. More than 800,000 new cancer cases require potentially curative or palliative RT services in Africa, arguably <15% of these patients currently have access to this important service. For a population of more than 206 million, Nigeria requires a minimum of 280 RT machines for the increasing number of cancer cases. Painfully, the country has only eight Government-funded RT machines. This study aimed to evaluate the status of the eight Government-funded RT services in Nigeria and their ability to deliver effective RT to their patients. METHODS A survey addressing 10 critical areas was used to assess the eight Government-funded RT services in Nigeria. RESULTS Unfortunately, six of the eight centers (75%) surveyed have not treated patients with RT because they do not have functioning teletherapy machines in 2021. Only two RT centers have the capability of treating patients using advanced RT techniques. There is no positron emission tomography-computed tomography scan in any of the Government-funded RT centers. The workforce capacity and infrastructure across the eight centers are limited. All of the centers lack residency training programs for medical physicists and radiation therapy technologists resulting in very few well-trained staff. CONCLUSION As the Nigerian Government plans for the new National Cancer Control Plan, there is an urgent need to scale up access to RT by upgrading the RT equipment, workforce, and infrastructure to meet the current needs of Nigerian patients with cancer. Although the shortfall is apparent from a variety of RT-capacity databases, this detailed analysis provides essential information for an implementation plan involving solutions from within Nigeria and with global partners.
Curating with Counterpowers
Authors: Grindon Gavin 
Published: June 2023

AbstractThis article examines the turn in Anglophone protest cultures since 2007 toward curating, museums, and heritage: a rise in the toppling of statues, demonstrations inside museums, and the creation of exhibitions, displays, and archives within the ephemeral spaces of protest camps and other mobilizations. The author argues for the historical causes of this curatorial turn in movement cultures, examines the structural power dynamics of this extrainstitutional curating vis-à-vis the practices and policies of cultural institutions, and puts these developments in critical dialogue with recent debates on “activist curating” and “institutional liberation.” Lastly, drawing on this analysis and firsthand experiences on both sides of this dynamic (as a core member of the collective Liberate Tate and as cocurator of the V&A exhibition Disobedient Objects), the author assesses this trajectory's potentials and limits as a cultural strategy for social change.
Life outside the Labor Process
Authors: McCallum Jamie K. 
Published: June 2023

Abstract
This memorial essay is a personal and sociological reflection on what it was like to learn from Stanley Aronowitz, both as his student and as his friend. Close attention is paid to what many consider his best book, False Promises, and its major insight: that class consciousness forms outside the labor process — through games, play, sex, and community organizing — as much as from within it.
Two feedback mechanisms involved in the control of leaf fragment size in leaf-cutting ants
Authors: Römer Daniela , Exl Rebecca , Roces Flavio 
Published: June 2023

ABSTRACT
Polymorphic leaf-cutting ants harvest leaf fragments that correlate in size with the workers' body size. When cutting, workers anchor their hind legs on the leaf edge and rotate, removing approximately semicircular fragments. Workers show behavioural plasticity and modify their leg extension while holding onto the leaf edge depending on, for instance, leaf toughness, cutting smaller fragments out of tough leaves. What sensory information workers use to control the cutting trajectory remains unknown. We investigated whether sensory information from both the leg contact with the leaf edge and from head movements underlies fragment size determination. In the laboratory, we recorded Atta sexdens workers cutting standardised ®Parafilm pseudoleaves of different thickness, and quantified cutting behaviour and body reach, i.e. the distance between the mandible and the anchored hind leg tarsus. Experimentally preventing contact with the leaf edge resulted in smaller fragments, evincing that workers control the cutting trajectory using information from the contact of the hind legs with the leaf edge. However, ants were able to cut fragments even when contact of all six legs with the edge was prevented, indicating the use of additional sensory information. Ablation of mechanosensory hairs at the neck joint alone did not influence fragment size determination, yet simultaneously preventing sensory feedback from both mechanosensory hairs and edge contact led to a loss of control over the cutting trajectory. Leaf-cutting ants, therefore, control their cutting trajectory using sensory information from both the leg contact with the leaf edge and the lateral bending of the head.
The COVID-19 third wave in Myanmar following the military coup
Authors:   Spring Research Team
Published: June 2023

Background: COVID-19 has disrupted health system of many countries, particularly worse in those resource limited settings including Myanmar. First and second waves in Myanmar during 2020 were effectively managed by the government. However, the momentum was disrupted due to the military coup in early 2021. This study aimed to analyse the situation of COVID-19 occurrence and death proportions during its third wave in Myanmar. Methods: An online survey was conducted using a Google form. People with the symptoms of COVID-19 and those who died from COVID-19 between June-August 2021 were eligible to participate. The Google form was extracted into an Excel datasheet and analysed using Stata v16.1. Results: Among the 29,171 participants, 76.7% were over 30 years old and 56.4% were female. A majority of participants were from highly populated regions: Yangon (17,220; 59%) (Business capital), Mandalay (3,740; 12.8%) and Sagaing (1,546; 5.3%). Participants sought health care from telegram/other online services (34%), home care by health care providers (22%), private clinics (13%) and public hospitals run under the military junta (5%). Overall, 15% of participants died, of which, 72% occurred at home and 17% at public hospitals. Significantly higher proportions of deaths were seen among participants over 60 years than other age groups and males (p<0.001). Death proportions at different weeks from June to August 2021 ranged from 12.4% to 17.3%, much higher than the military junta’s reports. Overall, 25% of participants received oxygen therapy. Conclusions: Death proportions in different weeks were consistently high with limited access to public hospital care during the third wave. The data suggests that COVID-19 third wave severely hit Myanmar, with adverse outcome fueled by the military coup. However, the online Telehealth clinics operated by Ministry of Health, Myanmar National Unity Government, offered the alternative accessible solution for the certain population within the country.

Published: June 2023

Aim of the studyVaginismus is the presence spasm of the muscles in the vagina in the absence of any disease. Neurological diseases can cause degenerative changes in brain structures such as the corpus callosum (CC).
The aim of this study is to evaluate the corpus callosum of patients with vaginismus with statistical shape analysis (SSA) using magnetic resonance imaging (MRI) images and compare it with healthy controls.Subject or material and methodsTen female patients with vaginismus and healthy individuals who met the study criteria, were equal in number and age were selected as the control. Mid-sagittal T1-weighted MRI images of each individual were obtained, and the corpus callosum was marked with software on each image using anatomical landmarks, and data were collected. The mean of 'Procrustes' landmarks was calculated and shape deformations were evaluated using thin plate spline (TPS) analysis.ResultsA significant slightly difference was found in terms of corpus callosum areas in the mid-sagittal images of patients with vaginismus and controls. Maximum CC deformation was observed in almost all regions markings in those with vaginismus. In the evaluation of allometry, multivariate regression test was used for the relationship between size and shape and a statistically significant model was obtained for CC.DiscussionCC analysis with SSA using MRI images revealed significant differences between patients and healthy subjects.ConclusionsThe study findings highlighted the abnormal distribution of white matter in the corpus callosum and the variable subregional nature of CC in vaginismus patients. This study may help future studies in terms of vaginismus etiology, diagnosis and treatment options.
Latent Agents in Networks: Estimation and Targeting
Authors: Ata Baris , Belloni Alexandre , Candogan Ozan 
Published: June 2023

Latent Agents in Networks: Estimation and Targeting In “Latent Agents in Networks: Estimation and Targeting,” Baris Ata, Alexandre Belloni, and Ozan Candogan address the problem of estimating network effects in a setting in which data only on a subset of agents is available. In this setting, the observable agents influence each other’s outcomes both directly and indirectly through their influence on the latent agents. Even in sparse networks, the combination of direct and indirect network effects yields a nonsparse influence structure that makes estimation challenging. The authors overcome this challenge and provide an estimation algorithm that performs well in high-dimensional settings. They also establish convergence rates for their proposed estimator and show that their performance guarantees are valid for a large class of networks. Finally, the authors demonstrate the application of their algorithm to a targeted advertising problem, in which it can be used to obtain asymptotically optimal advertising decisions despite the presence of latent agents.
The Strategic Adoption of Environmental Corporate Social Responsibility with Network Externalities
Authors: Xing Mingqing , Lee Sang-Ho 
Published: June 2023

Abstract
This paper adopts a green managerial delegation model in a polluting network industry wherein consumers form fulfilled rational expectations of network externalities. We show that firms are consistently incentivized to undertake ECSR (environmental corporate social responsibility) under price competition, while positive network externalities can increase the strategic level of ECSR. We also show that product substitutability between network products can play an important role in determining a firm’s strategic level of ECSR and resulting profits. Finally, ECSR is conducive to increasing environmental quality and social welfare in a high-polluting network industry. Therefore, the strategic adoption of ECSR in a network industry is Pareto-improving as environmental damage becomes serious.
“Tis Early Practice only Makes the Master”: Nature and Nurture in Economic Thinking During School Time – A Research Note on Economics Education
Authors: Roetzel Peter Gordon , Roetzel Lina 
Published: June 2023

AbstractIn this article, we contribute to the longstanding debate among economists regarding the question of “nature or nurture” with respect to economics students’ attitudes toward various allocation mechanisms for a scarce resource. While previous research starts the debate by beginning with first-year economics students, we aim to evaluate pre-first-year individuals, i.e., school pupils. Drawing on the seminal works of Haucap, J., & Just, T. (2010). Not guilty? Another look at the nature and nurture of economics students.European Journal of Law and Economics,29(2), 239–254 and Frey, B. S., Pommerehne, W. W., & Gygi, B. (1993). Economics indoctrination or selection? Some empirical results.The Journal of Economic Education,24(3), 271–281, we investigate a sample of 697 pupils ranging from the 5th to the 13th grades to determine whether pupils are “born economists” (nature), develop economic thinking (nurture), or both. We find that young individuals start to think differently in early grades and that their thinking and attitudes are shaped differently throughout their school careers, thereby providing support for the effects of both nature and nurture. Our findings show that school time impacts fairness judgments, particularly regarding price mechanisms. Regarding learning or indoctrination, we find that economics-inclined pupils are positively affected by lessons in economics in school, while pupils who are economics-averse draw completely diametric conclusions from economics lessons, thereby exhibiting increased disapproval of price allocation over the course of these classes and increased approval of the first come, first served and governmental action mechanisms. Moreover, we find strong effects of gender and migration background in this context. This study is the first to elucidate the development of economic thinking in 5th–13th grade pupils. Our results are important for economists, educators, and researchers because they can serve as a starting point for subsequent investigations in this under-researched field.
Depletion zones of groundwater resources in the Southwest Desert of Iraq
Authors: Shlash Marwah Abdullah , Obead Imad Habeeb 
Published: June 2023

Abstract
Aquifers offer a reliable supply of high-quality water, making groundwater significant in arid and semi-arid regions. Climate change is predicted to result in a decrease in rainfall and an increase in droughts. The prolonged drought severely devastated Iraq and is the main reason for the ongoing increase in groundwater consumption over the last decade. In this study, the stresses and depletion potentials of the Dammam confined aquifer, which extended along the Najaf and Muthanna governorates, are identified and analyzed. By using the Groundwater Modelling System (GMS v10.4) software, a numerical simulation of groundwater flow was used to study the Dammam aquifer system. The upper layer was modeled as unconfined, while the bottom layer was confined. The findings from the steady-state calibration indicate that the hydraulic conductivity (HK) within the study area varies between 1.47 to 20.0 m/day. Additionally, the recharging rate (RH) was estimated to be approximately 1.66 × 10−6 m/day. These parameters were utilized as the initial condition for conducting the transient analysis. Two operating scenarios were employed to perform unsteady simulations. The initial scenario involved the utilization of 89 production wells, while the second scenario included all 139 stand-by production wells, resulting in a total of 228 wells for the operational period from July 2021 to June 2022. The results of the first operation scenario showed that the drawdowns ranged from 0.4 to 5.8 m, whereas the second operation scenario showed that the drawdown increased from 1.0 to 22 m. The depletion rate in the groundwater static heads was measured by the percentage of relative difference. Hence, the depletion rate for the first scenario varied from 4.32 to 33.34%. On the other hand, the second scenario ranged from 7.45 to 33.34%.
Investigation of high-turbidity tap water problem in Najaf governorate/middle of Iraq
Authors: Abed Zahraa H. , Khudair Kifah M. 
Published: June 2023

Abstract
Turbidity is a fundamental measure for assessing the quality of water supplied by water treatment plants (WTPs) employing a conventional treatment process. If it is present in amounts exceeding the permitted limit, disinfectants are less effective in killing microorganisms and the water becomes unsafe to drink. This article is a part of a comprehensive study that aims to investigate the high-turbidity problem of tap water in two cities of Najaf governorate and offer suitable measures to solve this problem. The purpose of this study was to determine how WTPs impact the turbidity of tap water. The work covered two main WTPs located in Najaf governorate: Unified Najaf and The Old Kufa. It included the collection of water samples from three locations in each plant: the influent of flash mix unit (raw water samples), the effluent of clariflocculation unit (settled water samples), and the effluent of filtration unit (filtered water samples). The samples were analyzed for turbidity using a turbidity meter. The efficacy of each plant's treatment units was revealed by monitoring the turbidity of the water inside each facility. For the Unified Najaf WTP, out of 99 TRE readings, there were 3, 92, and 60 positive values for TREc, TREf, and TREp, respectively. The maximum values of TREc, TREf, and TREp were 22.3, 86.5, and 61.5%, respectively. The performance of Old Kufa WTP was worse than that of Unified Najaf WT. Out of 99 TRE values, the number of positive values was 6, 76, and 31 for TREc, TREf, and TREp, respectively. They also showed that only 26 out of 99 and 9 out of 99 effluent turbidity readings in Unified Najaf and Old Kufa WTPs, respectively, satisfy Iraqi standards for tap water turbidity. The bad performance of the WTPs was the main reason behind the high-turbidity tap water in Najaf governorate. This study identified the causes of that performance and proposed solutions.
Government Bond Spreads in the Euro Area
Authors: Carnot Nicolas , Pamies Stéphanie 
Published: June 2023

Abstract
In the euro area, the sovereign debts of all Member States aspire to be equally safe but investors persistently discriminate between country debts. Empirically, the evidence suggests a clear role of ‘fundamentals’ in explaining government bond spreads between euro area countries. In particular, the level of indebtedness is found to weigh strongly on spreads in a non-linear fashion. Fiscal factors may however be tempered, or conversely exacerbated, by other factors including the external position, potential growth, and institutional quality. Notwithstanding other pressing policy priorities such as the energy transition and climate change, policy reforms aimed at credibly ensuring sustainable national debts therefore remain central to the governance equilibrium of the euro area.

AbstractA massive use of nitrogen based fertilizers in agriculture is worldwide one of the main causes for nitrate contamination of groundwater. Methods for removing nitrate from aquatic environment through physical and/or chemical processes often turn out to be not applicable because of unaffordable financial resource as well as essential infrastructure lack. On the other hand, biological processes seem to have potentiality to overcome these limitations since they are less expensive and easier to be performed. Accordingly, in the present work, a moving bed biofilm reactor (MBBR) filled with Kaldnes K1 as carrier media was used to remove nitrate from a synthetic groundwater at bench scale. Acetate was used as organic source. Different operational conditions were tested: influent nitrate concentrations of 30, 40, 50 and 60 mg/L; hydraulic retention times of 24, 18, 12 and 8 h; and COD/NO3-N mass ratios of 3.00 and 2.98. Experimental results showed that NO3-N = 60 mg L−1, HRT = 8 h and COD/NO3-N ratio = 2.98 were the optimal operating conditions that allowed achieving a NO3-N removal by 99 % and a COD removal by almost 100 %. Moreover, almost no NO2−-N accumulation and null COD concentration were observed at the optimal operating conditions. An activated carbon filter was placed downstream to remove residual organic compounds prior to disinfection unit, thus avoiding the potential formation of harmful disinfection by-products (e.g. trihalomethanes (THMs)). The MBBR was able to show a rapid recovery whenever the operating conditions were defined as more severe, thus proving that the operating conditions can vary over a wider range. Furthermore, the results showed that the MBBR system can be used effectively as a biological process to remove nitrate from groundwater.
Hektik pur: zu den unflektierten nachgestellten Adjektiven im Deutschen und zu deren Wiedergabe im Italienischen
Authors: Masiero Federica 
Published: June 2023

Abstract
Englisch: The paper focuses on a peculiar German nominal construction which contains a certain type of uninflected postnominal adjectives that are used attributively. These adjectives have a semantically intensifying function as in for example Hektik pur and they constitute a small closed list (brutal, light, pur, total, satt). The central aim of this paper consists in presenting and evaluating different proposals for the translation of this particular German construction into Italian on the basis of an empirical analysis of concrete examples. Furthermore, the article analyses how the construction under study is treated in current German grammatical writing, discusses its syntax and offers some novel theses on its semantics.
On computation of neighbourhood degree sum-based topological indices for zinc-based metal–organic frameworks
Authors: Ravi Vignesh , Desikan Kalyani , Chidambaram Natarajan 
Published: June 2023

AbstractThe permeable materials known as metal–organic frameworks (MOFs) have a large porosity volume, excellent chemical stability, and a unique structure that results from the potent interactions between metal ions and organic ligands. Work on the synthesis, architectures, and properties of various MOFs reveals their utility in a variety of applications, including energy storage devices with suitable electrode materials, gas storage, heterogeneous catalysis, and chemical assessment. A topological index, which is a numerical invariant, predicts the physicochemical properties of chemical entities based on the underlying molecular graph or framework. In this article, we consider two different zinc-based MOFs, namely zinc oxide and zinc silicate MOFs. We compute 14 neighbourhood degree sum-based topological indices for these frameworks, and the numerical and graphical representations of all the aforementioned 14 indices are made.
