Diversification of Archean tonalite-trondhjemite-granodiorite suites in a mushy middle crust
Authors: Kendrick Jillian , Duguet Manuel , Yakymchuk Chris 
Published: September 2021

Abstract
Tonalite-trondhjemite-granodiorite (TTG) suites are the dominant component of Earth's first continents, but their origins are debated. The trace element concentrations of these rocks are conventionally linked to their source depths and inferred geodynamic settings with the implicit assumption that TTG compositions are source-controlled. Alternatively, their variable compositions may be caused by fractional crystallization in TTG plutons after emplacement and less clearly linked to source depth. Most TTGs in Archean mid-crustal exposures are the dominant component of igneous gray gneiss complexes; the processes that influence the evolution of TTG magmas in this setting are poorly understood. We present a petrological–geochemical model that explains the coexistence of TTGs in the middle crust with low-pressure and high-pressure geochemical trends, irrespective of tectonic setting or depth of the TTG source. We propose that mid-crustal TTGs were long-lived crystal mushes with compositions controlled by the separation of early-crystallizing plagioclase and melt. Using phase equilibrium modeling, we demonstrate that a suite of TTGs from the southern Superior Province in Canada represents variably plagioclase-rich and melt-rich fractions from a common parent magma. The behavior of plagioclase may have a strong influence on the geochemical trends of TTGs, including the degree of rare earth element fractionation. Our results suggest that trace element compositions of TTGs may not primarily reflect the depth of the source and cannot be used alone to infer Archean geodynamic settings.
Mantle heating at ca. 2 Ga by continental insulation: Evidence from granites and eclogites
Authors: Tamblyn R. , Hasterok D. , Hand M. , Gard M. 
Published: September 2021

Abstract
Igneous and metamorphic rocks contain the mineralogical and geochemical record of thermally driven processes on Earth. The generally accepted thermal budget of the mantle indicates a steady cooling trend since the Archean. The geological record, however, indicates this simple cooling model may not hold true. Subduction-related eclogites substantially emerge in the rock record from 2.1 Ga to 1.8 Ga, indicating that average mantle thermal conditions cooled below a critical threshold for widespread eclogite preservation. Following this period, eclogite disappeared again until ca. 1.1 Ga. Coincident with the transient emergence of eclogite, global granite chemistry recorded a decrease in Sr and Eu and increases in yttrium and heavy rare earth element (HREE) concentrations. These changes are most simply explained by warming of the thermal regime associated with granite genesis. We suggest that warming was caused by increased continental insulation of the mantle at this time. Ultimately, secular cooling of the mantle overcame insulation, allowing the second emergence and preservation of eclogite from ca. 1.1 Ga until present.

Allometric models embedding independent variables such as diameter at breast height (d) and total height (h) are useful tools to predict the biomass of individual trees. Models for tropical forests are often constructed based on datasets composed of species with different morphological features and architectural models. It is reasonable to expect, however, that species-specific models may reduce uncertainties in biomass predictions, especially for palms, tree ferns, and trees with peculiar morphological features, such as stilt roots and hollow trunks. In this sense, three species with wide geographical distribution in the Brazilian Atlantic Forest were sampled, namely Euterpe edulis Mart., Cyathea delgadii Sternb., and Cecropia glaziovii Snethl., with the aim to (i) quantify their aboveground biomass (AGB), (ii) evaluate the AGB distribution in different plant compartments, (iii) fit species-specific models for predicting AGB at the individual level, and (iv) assess the performance of specific and generic models available in the literature to predict the AGB of individuals of these species. The compartment stem represented, on average, ∼74% of the total AGB of E. edulis individuals; in turn, the caudex compartment of C. delgadii represented, on average, ∼87% of the total AGB, while the trunk compartment of C. glaziovii represented, on average, ∼74%. Among the fitted models, the power model [Formula: see text] showed the best performance for E. edulis and C. delgadii. In turn, the asymptotic logistic model [Formula: see text], where dc is the diameter above the upper stilt root, presented the best performance for C. glaziovii. The variable h appeared as the most important predictor of AGB of E. edulis and C. delgadii; in contrast, the stem and caudex mean basic specific gravities were not suitable predictors. The fitted species-specific models outperformed the specific and generic models selected from the literature. They may, therefore, contribute to the reduction of uncertainties in AGB estimates. In addition, the results support evidence that specific models may be necessary for species with different growth forms and (or) peculiar morphological features, especially those with great abundance and wide geographic distribution.

Published: September 2021

Probiotic-based therapies have been shown to be beneficial for chemotherapy-induced mucositis. Previous research has demonstrated that a probiotic mixture (Bifidobacterium brevis, Lactobacillus acidophilus, Lactobacillus casei, and Streptococcus thermophilus) can ameliorate chemotherapy-induced mucositis and dysbiosis in rats, but the underlying mechanism has not been completely elucidated. We aimed to determine the inhibitory effects of the probiotic mixture on cisplatin-induced mucositis and pica and the underlying mechanism, focusing on the levels of 5-hydroxytryptamine (5-HT, serotonin) regulated by the gut microbiota. A rat model of mucositis and pica was established by daily intraperitoneal injection of cisplatin (6 mg/kg) for 3 days. In the probiotic+cisplatin group, predaily intragastric injection of the probiotic mixture (

Histopathology, pro-/anti-inflammatory cytokines, oxidative status, and 5-HT levels were assessed on days 3 and 6. The structure of the gut microbiota was analyzed by 16S rRNA gene sequencing and quantitative PCR. Additionally, 5-HT levels in enterochromaffin (EC) cells (RIN-14B cell line) treated with cisplatin and/or various probiotic bacteria were also determined. The probiotic mixture significantly attenuated kaolin consumption, inflammation, oxidative stress, and the increase in 5-HT concentrations in rats with cisplatin-induced intestinal mucositis and pica. Cisplatin markedly increased the relative abundances of Enterobacteriaceae_other, Blautia, Clostridiaceae_other, and members of Clostridium clusters IV and XIVa. These levels were significantly restored by the probiotic mixture. Importantly, most of the genera increased by cisplatin were significantly positively correlated with colonic 5-HT. Furthermore, in vitro, the probiotic mixture had direct inhibitory effects on the 5-HT secretion by EC cells. The probiotic mixture protects against cisplatin-induced intestine injury, exhibiting both anti-inflammatory and antiemetic properties. These results were closely related to the reestablishment of intestinal microbiota ecology and normalization of the dysbiosis-driven 5-HT overproduction.

Published: September 2021

Background and Purpose:
Patients presenting in the extended time window may benefit from mechanical thrombectomy. However, selection for mechanical thrombectomy in this patient group has only been performed using specialized image processing platforms, which are not widely available. We hypothesized that quantitative lesion water uptake calculated in acute stroke computed tomography (CT) may serve as imaging biomarker to estimate ischemic lesion progression and predict clinical outcome in patients undergoing mechanical thrombectomy in the extended time window.

Methods:
All patients with ischemic anterior circulation stroke presenting within 4.5 to 24 hours after symptom onset who received initial multimodal CT between August 2014 and March 2020 and underwent mechanical thrombectomy were analyzed. Quantitative lesion net water uptake was calculated from the admission CT. Prediction of clinical outcome was assessed using univariable receiver operating characteristic curve analysis and logistic regression analyses.

Results:

One hundred two patients met the inclusion criteria. In the multivariable logistic regression analysis, net water uptake (odds ratio, 0.78 [95% CI, 0.64–0.95],
P
=0.01), age (odds ratio, 0.94 [95% CI, 0.88–0.99];
P
=0.02), and National Institutes of Health Stroke Scale (odds ratio, 0.88 [95% CI, 0.79–0.99],
P
=0.03) were significantly and independently associated with favorable outcome (modified Rankin Scale score ≤1), adjusted for degree of recanalization and Alberta Stroke Program Early CT Score. A multivariable predictive model including the above parameters yielded the highest diagnostic ability in the classification of functional outcome, with an area under the curve of 0.88 (sensitivity 92.3%, specificity 82.9%).

Conclusions:
The implementation of quantitative lesion water uptake as imaging biomarker in the diagnosis of patients with ischemic stroke presenting in the extended time window might improve clinical prognosis. Future studies could test this biomarker as complementary or even alternative tool to CT perfusion.
An Offer You Can Refuse: A Host Country's Strategic Allocation of Development Financing
Authors: Hwang Jyhjong 
Published: September 2021

Abstract
Hydropower projects are one of the leading energy sectors being developed in Africa. In the past two decades, this demand has been increasingly met by Chinese financing and Chinese contractors, creating an impression that host countries have no choice but to accept Chinese advances against their preferences. This essay demonstrates through the case study of the Mount Coffee hydropower project in Liberia that host countries strategically allocate financing from different sources to different projects, based on domestic development needs, administrative capacity, flexibility of financiers, and institutional memory between the host and the financiers. This essay also shows that concerns over Chinese contractors' environmental- and social-impact records reflect a combination of host enforcement, financier self-sorting, and Chinese contractors' own perceptions of their comparative advantage. More broadly, this case study provides empirical observations of host countries' agency and strategic calculus in the financier-host relation, as well as the limits of China's role in Africa's hydropower sector.

Published: September 2021

Abstract
Organisms face numerous environmental stressors, which can affect developmental precision, including symmetry of various physical characteristics. Fluctuating asymmetry (FA) has therefore been suggested as a simple and efficient tool for assessing sub-lethal stress levels. We analyzed FA in two sympatric lizard species (Iberolacerta horvathi and Podarcis muralis) to determine potential effects of interspecific competition and urbanization, as proxies of stress, taking into account sexual dimorphism and environmental conditions. We sampled 16 syntopic and allotopic populations and used geometric morphometrics of head morphology. We detected significant but mixed effects on the head asymmetry from the environment and the syntopic occurrence that differed between species. P. muralis lizards had more asymmetric heads at higher altitudes, while I. horvathi lizards did at mid altitudes, which may be explained by P. muralis experiencing environmental stress of colder conditions at higher altitudes. The mid-altitude effect on asymmetries in I. horvathi might be explained by a lower availability of stony walls and higher abundance of P. muralis, thus higher competition. The asymmetry of supraciliary granules was affected by the presence of other species. However, lizards from allotopic populations attained larger asymmetries compared to lizards from syntopic populations, which was the opposite from what was expected. There was no effect of urbanization in P. muralis, which could be due to relatively low pollution and habitat degradation in study locations. Overall, we highlighted the possibility of using lizards and FA for bioindication of environmental stressors and especially improved the knowledge gap in the research of biotic stressors.
The Population of European Cities from 700 to 2000
Authors: Buringh Eltjo 
Published: September 2021

Abstract
This article presents an expanded dataset of the historical urban population in Europe, European urban population, 700–2000 (https://www.doi.org/10.17026/dans-xzy-u62q). This dataset contains new and improved estimates of the urban population (in thousands of inhabitants) between the years 700 and 2000 in 2,262 European settlements, including European cities with more than 100,000 inhabitants. The dataset is based on previous historical demographic sources that have been critically assessed and systematically complemented with new population estimates for additional time windows, deriving from either quantitative sources or proxies. Missing data are covered by city-specific and time-specific imputations. The applied time windows are whole centuries before 1500 and half a century afterwards. The article discusses the robustness checks that have been performed to validate the reliability of the imputed numerical results.
A Threat to Invade Cyprus: Pope John XXII, Walter of Brienne Duke of Athens, and the Latin East in 1331
Authors: Edbury Peter W. 
Published: September 2021

Abstract
The Brienne family first laid claim to the throne of Cyprus in the 1260s. The family subsequently rose high in the service of the Angevin kings of Naples and continued to assert their claim from time to time, but they seem never to have been a serious threat to Lusignan rule. Nevertheless, recently discovered papal letters demonstrate that as late as 1331 there were concerns that Walter VI of Brienne, duke of Athens, would divert to Cyprus a planned expedition against the Catalans occupying his duchy. Although King Robert the Wise of Naples was the rival of King Hugh IV of Cyprus for the title of king of Jerusalem, the letters also reveal that Pope John XXII called upon Robert to prevent such an invasion, as other newly uncovered letters show the pope to have done when the Genoese threatened to send invasion fleets to the island in 1317 and 1328. The new letters are published in an appendix.
Samuel Khachikian and the Crime Thriller in Iran
Authors: Askari Kaveh 
Published: September 2021

Abstract
Samuel Khachikian was the most successful director of crime films in Iran during the genre’s heyday in the late 1950s and early 60s. Debates among critics about his films highlight how the crime film was able to thrive as a prestige form in the years before boundaries had solidified between commercial films and intellectual films made in Iran. Film noir, from its earliest transatlantic imaginings to its recent global circuits, has consistently engaged with an imagined elsewhere through its modernist style. In many parts of the world, it allowed a kind of performance of exuberant cinephilia while also attracting attention about its originality. In Tehran, as elsewhere, the genre accompanies the global circulation of modern design with strong, but mixed, feelings.
Understanding the impact of mandatory accrual accounting on management practices: interpretation of Japanese local governments’ behavior
Authors: Kuroki Makoto , Ishikawa Keiko , Yamamoto Kiyoshi 
Published: September 2021

Accompanying the spread of “new public management” since the 1980s, accrual accounting and results-based management has become a global standard. However, whether accrual accounting results in successful outcomes and which drivers lead to the intended impacts of the reform have been contested. Given the mixed arguments in the literature, we set out two research questions: (1) “Have public sector organizations realized any positive impacts on management practices by adopting mandatory accrual accounting?”; and (2) “What are the primary drivers of such impacts?” To answer these questions, we examine the impact on management practices by analyzing a survey to ascertain how financial department officers in Japanese local governments perceive the benefits of adopting mandatory accrual accounting on management practices. The results indicate that they have so far not recognized the intended benefits, though they had expected higher benefits in internal control. Then, we use technical-rational, socio-political, and institutional isomorphic perspectives in a comprehensive approach to understand the impacts on management practices. The logistic analysis shows that financial managers in local governments that do not have a majority party in the assembly, but consist of several parties in power, as well as in those with greater financial dependence on the central government, perceive higher benefits. Further, we find that financial managers that imitate other local governments as a form of mimetic pressure perceive fewer benefits. The results show that some technical-rational tools, socio-political conditions, and institutional pressures change the perceived benefits for public managers of adopting mandatory accrual accounting. Points for practitioners We find that some technical-rational, socio-political, and institutional factors explain the intended internal benefits of the mandatory adoption of accrual accounting. In practice, financial managers in local government feel the merits of accrual accounting in less autonomy in not only politics, but also finance, and few mimetic conditions. It might be understood that difficult situations would drive practitioners to use mandatory information.

Objectives: This study aimed to evaluate the truthfulness of patients about their pre-appointment COVID-19 screening tests at a dental clinic. Methods: A total of 613 patients were recruited for the study from the dental clinic at the Faculty of Dentistry, Najran University, Saudi Arabia. The data collection was done in three parts from the patients who visited the hospital to receive dental treatment. The first part included the socio-demographic characteristics of the patients and the COVID-19 swab tests performed within the past 14 days. The second part was the clinical examination, and the third part was a confirmation of the swab test taken by the patient by checking the Hesen website using the patient ID. After data collection, statistical analysis was carried out using SPSS 26.0. Descriptive analysis was done and expressed as mean, standard deviation, frequency, and percentage (%). A cross-tabulation, also described as a contingency table, was used to identify trends and patterns across data and explain the correlation between different variables. Results: It was seen from the status of the swab test within 14 days of the patient's arrival at the hospital for the dental treatment that 18 (2.9%) patients lied about the pre-treatment swab test within 14 days, and 595 (97.1%) were truthful. The observed and expected counts showed across genders and diagnosis a statistically significant difference ( p < 0.001), and there was no significant difference seen across different age groups ( p = 0.064) of the patients. Conclusions: Dental healthcare workers are worried and assume a high risk of COVID-19 infection as the patients are not truthful about the pre-treatment COVID-19 swab test. Routine rapid tests on patients and the healthcare staff are a feasible option for lowering overall risks.
The fatigue and quality of life in patients with chronic pulmonary diseases
Authors: Szymanska-Chabowska Anna , Juzwiszyn Jan , Tański Wojciech , Świątkowski Filip , Kobecki Jakub , Chabowski Mariusz 
Published: September 2021

Background: Patients with pulmonary diseases often experience fatigue. Severe fatigue is associated with a worse health status and worse physical and social functioning. The study aimed to evaluate the relationship between fatigue and quality of life in patients with nonmalignant pulmonary diseases. Methods: The St George's Respiratory Questionnaire (SGRQ) was used to assess health status and the Fatigue Impact Scale (MFIS) to measure the level of fatigue. The Shapiro–Wilk test was used to test for normal distribution. Correlations were described as Spearman's rank correlation coefficient. Results: The study included 200 consecutive patients (mean age, 57.7) with the following diagnoses: COPD (26%), asthma (36%), obstructive sleep apnoea (19%), pneumonia or bronchitis of various aetiologies (8.5%), bronchiectasis (2.5%), interstitial lung disease (3%). The mean score in the SGRQ was 44.62 ± 24.94. The mean score in the MFIS was 28.64 ± 15.8. The strongest correlations appeared between quality-of-life scales and fatigue as measured by physical functioning (symptoms r = 0.622; activity r = 0.632; impact r = 0.692; p < 0.001 for all subscales); however, all the correlations between SGRQ and MFIS were significant. Conclusions: Patients with chronic pulmonary diseases were revealed to have a reduced level of quality of life and an increased level of fatigue. The negative influence of fatigue on quality of life highlights the need for careful and routine assessment of this symptom in pulmonary patients. Treating fatigue may improve quality of life and increase the ability of patients with chronic pulmonary diseases to perform activities in daily life.
