Published: November 2022

Purpose
Postoperative urinary dysfunction following lumbosacral spine surgery is devastating. To assess urinary function, we invented a pediatric urinary catheter equipped with electrodes for the direct transurethral recording of myogenic potential from the external urethral sphincter (EUS). This is the first report regarding the direct recording of motor-evoked potential (MEP) from EUS during lumbosacral spine surgery in children.
Methods
Two children (aged 2 and 6 years) were included in this study. One patient had no preoperative neurological dysfunction, while the other had frequent urination and urinary incontinence. A pair of surface electrodes was attached to a silicone rubber urethral catheter (6 or 8 Fr; diameter, 2 or 2.6 mm). The MEP from the EUS were recorded to assess the function of the centrifugal tract from the motor cortex to the pudendal nerve.
Results
Baseline MEP waveforms from the EUS were successfully recorded with latency and amplitude of 39.5 ms and 66 µV in patient 1 and 39.0 ms and 113 µV in patient 2, respectively. A significant decrease in amplitude was not observed during surgery in the two cases. No new urinary dysfunction and complications associated with the urinary catheter-equipped electrodes developed postoperatively.
Conclusion
Using an electrode-equipped urinary catheter, monitoring of MEP from the EUS could be applicable during lumbosacral surgery in pediatric patients.
Quality Aspects of Digital Forest Service Management: A Case Study
Authors: Jäntti Marko , Aho Markus
Published: November 2022

Forest industry plays a critical role for many remote rural regions in Nordic countries. Despite the increasing number of various digital transformation initiatives, many forestry organizations still use very tra- ditional non-digitalized work practices in harvesting, logging and support operations. Unfortunately, digital transformation is often performed as an ad hoc activity without a holistic approach to ensure ICT quality con- trol. In this paper, we aim to answer the research problem how digital transformation affects the quality of a forest machine operator’s opera- tional processes and service systems. A case study research method with a single case structure was used in this study. The main contribution of the paper is to show that digital transformation shall benefit not only the for- est machine operator organization but also their surrounding ecosystem by increasing transparency of operations, reducing travel costs, increas- ing productivity and creating a more proactive operating model. Both sociological and technical aspects of digital transformation are discussed in the context of forest service management. Additionally, we show that in order to succeed in digital transformation, forestry organizations must pay attention to various quality aspects holistically: hardware quality, software quality, service quality, data quality and process/project quality.

Authors: MAMADOU Ali , Chalhoub Gerard
Published: November 2022

Radio Access Technology (RAT) selection is an essential component in designing heterogeneous network coexistence to enable the diversity of future applications. In the 5G paradigm, many wireless technologies are available to ensure ubiquitous radio access. However, there are still open issues related to the decision-making process and Quality of Service (QoS) constraints consideration when it comes to selecting the most suitable wireless interface for a specific data transmission e.g. in Device-To-Device (D2D) communications. In this paper, we present MCDM-RAT: RAT Selection method between LTE-D2D and IEEE 802.11 formulated as a Multiple Criteria Decision Making (MCDM) problem with a decision data analysis mechanism that allows accurate network performance estimation in the decision making process. Full-stack network simulation results show the benefits of MCDM-RAT compared to baseline decision mechanisms. Our findings show the benefits of MCDM-RAT, under multiple network load conditions, in enhancing network performance perceived by end-users (in terms of delay, through-put, and data delivery rate), while considering simultaneously multiple QoS constraints.

Published: November 2022

Autism spectrum disorder (ASD) is a common neurodevelopmental condition. The American Academy of Paediatrics and American Academy of Neurology do not recommend routine brain magnetic resonance imaging (MRI) in the assessment of ASD. The need for a brain MRI should be decided on atypical features in the clinical history and examination. However, many physicians continue to use MRI brain routinely in the assessment process.
We performed a retrospective review of indications for requesting MRI brain in our institution over a 5-year period to determine. The aim was to was to identify the yield of MRI imaging in children with ASD and calculate the prevalence of significant neuroimaging abnormalities in children with ASD and identify clinical indications for neuroimaging
One hundred and eighty-one participants were analysed. An abnormal brain MRI was identified in 7.2% (13/181). Abnormal MRI brain was more likely with an abnormal neurological examination (OR 33.1, p=0.001) or genetic/metabolic abnormality (OR 20, p=0.02). In contrast, abnormal MRI was not shown to be more likely in children with a variety of other indications such as behavioural issues and developmental delay.
Thus, our findings support that MRI should not be a routine investigation in ASD, without additional findings. The decision to arrange MRI brain should be made on a case-by-case basis following careful evaluation of potential risks and benefits. The impact of any findings on the management course of the child should be considered prior to arranging imaging.

Published: November 2022

Acute lung injury is a critical acute respiratory distress syndrome (ARDS) with high morbidity and mortality. MicroRNAs (miRNAs) have been demonstrated to play important roles regulating acute lung injury development. In this study, we found that the expression of miR-598 was significantly upregulated in the lung tissues of mice with LPS-induced acute lung injury. Both loss-of function and gain-of-function studies were performed to evaluate the function of miR-598 in acute lung injury. The results showed that inhibition of miR-598 attenuated inflammatory response, oxidative stress and lung injury in mice treated with LPS, while overexpression of miR-598 exacerbated the LPS-induced acute lung injury. Mechanistically, transcription factor Early B-cell Factor-1 (Ebf1) was predicted and validated as a downstream target of miR-598. Overexpression of Ebf1 attenuated LPS-induced production of inflammatory cytokine TNF-α and IL-6, ameliorated LPS-induced oxidative stress, promoted proliferation and inhibited apoptosis in murine lung epithelial − 15 (MLE-15) cells. Moreover, we demonstrated that Ebf1 knockdown abolished the protective effect of miR-598 inhibition in MLE-15 cells. In summary, miR-598 inhibition ameliorates LPS-induced acute lung injury in mice through upregulating Ebf1 expression, which might provide potential therapeutic treatment for acute lung injury.

Published: November 2022

Strong light-matter interaction plays a central role in realizing quantum photonic technologies. The entanglement state, which results from the hybridization of excitons and cavity photons, forms the foundation of quantum information science. In this work, an entanglement state is achieved by manipulating the mode coupling between surface lattice resonance and quantum emitter into the strong coupling regime. At the same time, a Rabi splitting of 40 meV is observed. A full quantum model based on the Heisenberg picture is used to describe this unclassical phenomenon, and it perfectly explains the interaction and dissipation process. In addition, the observed concurrency degree of the entanglement state is 0.5, presenting the quantum non-locality. This work effectively contributes to the understanding of non-classical quantum effects arising from strong coupling and will intrigue more interesting potential applications in quantum optics.

Published: November 2022

Background: Acute myocardial infarction (MI) is a major health problem and is the leading cause of death worldwide. Myocardial apoptosis induced by myocardial infarction injury is involved in the pathophysiology of heart failure. Therapeutic stem cell therapy has the potential to be an effective and favorable treatment for ischemic heart disease. Exosomes derived from stem cells have been shown to effectively repair MI injury-induced cardiomyocyte damage. However, the cardioprotective benefits of adipose tissue-derived mesenchymal stem cell (ADSC)-Exos remain unknown. This study aimed to investigate the protective effects of exosomes from ADSC on the hearts of MI-treated mice and to explore the underlying mechanisms.
Methods: Cellular and molecular mechanisms were investigated using cultured ADSCs. On C57BL/6J mice, we performed myocardial MI or sham operations and assessed cardiac function, fibrosis, and angiogenesis 4 weeks later. Mice were intramyocardially injected with ADSC-Exos or vehicle-treated ADSCs after 25 min following the MI operation.
Results: Echocardiographic experiments showed that ADSC-Exos could significantly improve left ventricular ejection fraction, whereas ADSC-Exos administration could significantly alleviate MI-induced cardiac fibrosis. Additionally, ADSC-Exos treatment has been shown to reduce cardiomyocyte apoptosis while increasing angiogenesis. Molecular experiments found that exosomes extracted from ADSCs can promote the proliferation and migration of microvascular endothelial cells, facilitate angiogenesis, and inhibit cardiomyocytes apoptosis through miRNA-205. We then transferred isolated exosomes from ADSCs into MI-induced mice and observed decreased cardiac fibrosis, increased angiogenesis, and improved cardiac function. We also observed increased apoptosis and decreased expression of hypoxia-inducible factor-1α and vascular endothelial growth factor in HMEC-1 transfected with a miRNA-205 inhibitor.
Conclusion: In summary, these findings show that ADSC-Exos can alleviate cardiac injury and promote cardiac function recovery in MI-treated mice via the miRNA-205 signaling pathway. ADSC-Exos containing miRNA205 have a promising therapeutic potential in MI-induced cardiac injury.

Published: November 2022

Purpose
Patellar resurfacing in Total knee arthroplasty is considered standard in the United States. Complications of patella resurfacing include aseptic loosening or patella fractures possibly resulting in loss of the extensor mechanism.
The goal of this study was to evaluate the Genesis II patella button and to report its outcome and complications.
Material & Methods
Between 01/2010 and 08/2016 the Genesis II patella button was implanted in 1,056 patients (267 men and 550 women) by the senior author at the authors’ institution as part of a posterior stabilized total knee arthroplasty.
Results
Of 1,056 cases 35 cases (14 women, 15 men, 5 bilateral, 3.3%) showed early loosening of the Genesis patella button at a mean 52.5 months postoperatively. Buttons of 38mm and larger patella components showed a significantly higher loosening rate than the 29, 32, 35mm buttons (p<0.01). Mean BMI of patients identified with aseptic loosening was 31.7kg/m2, mean age at time of revision surgery was 63.3 years. All of the patients with loosening of the patella button required revision surgery; in 33 cases an exchange of the button was performed, in two cases a removal of the button and patellar bone grafting was indicated. No complications occurred after revision surgery.
Conclusion
The current study reports a 3.3% patella loosening rate in the short follow up for the Genesis II patella button. Button 35mm and larger showed a significantly higher revision rate than smaller buttons and the authors advise caution when using large diameter patella components.

Authors: Arunadevi M. , Sathya V.
Published: November 2022

Cloud computing facilitates users with on-demand services over the Internet. Depending on demand, cloud services are frequently utilized as private or public data forums, and the rise in usage has raised security issues. The distributed denial of service (DDoS) attack is one of these security risks that affect cloud computing services. In this work, the optimized back propagation neural network (BPNN) is proposed to detect DDoS attacks in the cloud environment. The proposed optimized BPNN is used artificial plant optimization (APO) algorithm for optimizing the weights and bias of the connections. The proposed APO-BPNN detection system is evaluated using four datasets namely, NSL-KDD, ISCX-IDS 2012, UNSW-NB15, and CIC-IDS 2017. The experiments show that the performance of the proposed APO-BPNN detection system is better than the system based on variant BPNN and state-of-the-art techniques.
Transpiration by sap flow Thermal Dissipation Method: applicability to a hedgerow olive orchard
Authors: Ferrara Rossana Monica
Published: November 2022

The climate change requires thrifty use of water resources in agriculture since irrigation is became common also for those crops like olive orchard that were traditionally grown in rainfed conditions. The water requirement is imperative in semi-arid conditions of the Mediterranean basin especially if the olive orchards are cultivated in super high density. For a correct irrigation scheduling, methods to measure transpiration (Tr) at plant level are used. Among the most spread methods to determine Tr, the thermal dissipation method (TDM) has been applied on a hedgerow olive orchard considering: (i) species-specific local calibration, (ii) wound effects, (iii) azimuth correction, and (iv) radial gradient corrections. The performances of the corrected TDM method have been evaluated with respect an independent method, the water balance at weekly scale. If any correction nor specific calibration is carried out, the underestimation of the actual transpiration calculated by TDM was of about − 18% with respect to the water balance method.
Localization and fractality in disordered Russian Doll model
Authors: Motamarri Vedant , Gorsky Alexander S. , Khaymovich Ivan
Published: November 2022

Motivated by the interplay of Bethe-Ansatz integrability and
localization in the Richardson model of superconductivity, we consider a
time-reversal symmetry breaking deformation of this model, known as the
Russian Doll Model (RDM), and implement diagonal on-site disorder. The
localization and ergodicity-breaking properties of the single-particle
spectrum are analyzed using a large-energy renormalization group (RG)
over the momentum-space spectrum. Based on the above RG, we derive an
effective Hamiltonian of the model, discover a fractal phase of
non-ergodic delocalized states – with the fractal dimension different
from the paradigmatic Rosenzweig-Porter model – and explain it in terms
of the developed RG equations and the matrix-inversion trick.

Estimating gabion weir oxygen transfer with data mining
Authors: Tiwari Nand Kumar , Luxmi K.M. , Ranjan Subodh
Published: November 2022

Conventionally, impermeable weirs are employed for retaining, measuring, and regulating the water in the river. Today, alternative devices are more predominantly in vogue, which are made of locally available materials called gabion weirs chosen because the latter can better fulfill ecological needs due to their porous nature. Dissolved oxygen (D.O.) is one of the significant determinants for assessing the character of water bodies. This study mainly focuses on improving the estimation of the gabion oxygen transfer efficiency (OTE20) to enhance its efficacy. The backpropagation neural network (BPNN), adaptive neuro-fuzzy inference system (ANFIS), and multi-variant linear and nonlinear regression (MVLR and MVNLR) are developed with experimental data to estimate the OTE20 and their results are compared. In terms of statistical metrics, the BPNN has proved to be the best-performing model. At the same time, triangular membership function (mf)-based ANFIS is the second-best performing model. Nevertheless, other applied mf-based ANFIS, MVLR, and MVNLR are giving a comparable performance. Input variable discharge per unit width (q) is the most crucial parameter in the computation of the OTE20, followed by the gabion mean size (d50). Major challenges are found in computing porosity of the gabion materials and optimal parameters of proposed data mining techniques.
Assessing Myocardial Involvement in Systemic Lupus Erythematosus Patients
without Cardiovascular Symptoms by Technetium-99m-sestamibi
Myocardial Perfusion Imaging: A Correlation Study on NT-proBNP
Authors: Shao Kejing , Yuan Fenghong , Chen Fei , Wang Jianfeng , Shao Xiaoliang , Zhang Feifei , Zhu Bao , Wang Yuetao
Published: November 2022

Background:

In patients with systemic lupus erythematosus (SLE), myocardial involvement
is the third leading course of death after lupus nephropathy (LN) and infections. Previous autopsy studies
have demonstrated a high incidence of cardiovascular abnormalities in the myocardium. However,
the patients with typical symptoms are far much fewer than expected from post-mortem examinations.

Objectives:

The current study aimed to evaluate the technetium-99m-sestamibi (99mTc-MIBI) gated
myocardial perfusion imaging (GMPI) characteristics of lupus patients without cardiovascular symptoms,
and the relationships between GMPI characteristics and biochemical markers of myocardial injury,
and to explore the role of GMPI in assessing myocardial involvement.

Methods:

Thirty patients were studied with rest myocardial perfusion imaging, and summed rest score
(SRS), summed motion score (SMS), and summed thickening score (STS) were calculated automatically.
Biomarkers, including N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and
creatine-kinase-MB (CK-MB), were detected simultaneously. GMPI parameters, LV functions and
biomarkers were compared between two NT-proBNP groups. The relationships between these parameters
were studied by correlation analysis.

Results:

SMS, STS, and glomerular filtration rate (eGFR) were the main influencing factors of NTproBNP
level (p = 0.001, <0.001, 0.042, respectively). Thirteen patients with an evaluated concentration
of NT-proBNP had the lower left ventricular ejection fraction (LVEF), peak filling rate (PFR),
eGFR and higher levels of CK-MB (in all comparisons, p < 0.05), and SRS was the only influencing
factor of NT-proBNP (p = 0.007). Within thirteen patients with SRS≥2, there was a significant correlation
between SRS and NT-proBNP (p < 0.001).

Conclusion:

99mTc-MIBI GMPI could evaluate the left ventricular function and prompt the cardiomyocyte
function at the cellular level. SMS and STS were the main influencers for plasma NT-proBNP,
and SRS was the independent factor for elevated NT-proBNP. This radionuclide imaging method
could provide additional diagnostic information on myocardial involvement in patients with SLE.
Non-surgical Treatment of a Late Adolescent Patient with Skeletal Class II Malocclusion Using Clear Aligners: A Case Report
Authors: Robertson Lindsay J. , El-Bialy Tarek
Published: November 2022

Background/Introduction:

There are a variety of treatment modalities for orthodontic treatment of patients with skeletal Class II malocclusions in late adolescence. These treatment modalities may include surgical intervention, camouflage treatment, functional appliances, extraction of teeth, and/or Class II elastics mechanics. Most Class II mechanics produce retroclination of the upper incisors and proclination of lower incisors. These dentoalveolar effects limit the possibility for forward mandibular projection/growth, hence minimizing skeletal improvement.

Case Presentation:

To present a unique case report that was treated with a new perspective in maximizing skeletal improvement in a late adolescent male with skeletal Class II malocclusion and deep overbite.

A 15-year-old male presented with a skeletal Class II pattern due to mandibular retrognathism was treated with non-extraction, non-surgical technique using clear aligners in two phases. Phase 1 was designed to decompensate the compensated inclination of his anterior teeth, and phase II was planned to correct his skeletal and dental Class II malocclusion/mal relation. Results: Maxillary incisors decompensation of the inclination of the upper and lower incisors and posterior teeth intrusion allowed forward mandibular projection that led to skeletal and dental correction of his malocclusion and improvement of his chin forward projection.

Conclusion:

This case report shows successful treatment of a Class II malocclusion in alate adolescent male. This method could perhaps be used for similar cases, avoiding the need to extract teeth or include surgical intervention.

Published: November 2022

Fruit, vegetables, and green tea contain quercetin (a flavonoid). Some of the diet's most significant
sources of quercetin are apples, onions, tomatoes, broccoli, and green tea. Antioxidant, anticancer,
anti-inflammatory, antimicrobial, antibacterial, and anti-viral effects have been studied of quercetin. The
severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus, ribonucleic acid (RNA) polymerase,
and other essential viral life-cycle enzymes are all prevented from entering the body by quercetin.
Despite extensive in vitro and in vivo investigations on the immune-modulating effects of quercetin and
vitamin C treatment. 3-methyl-quercetin has been shown to bind to essential proteins necessary to convert
minus-strand RNA into positive-strand RNAs, preventing the replication of viral RNA in the cytoplasm.
Quercetin has been identified as a potential SARS-CoV-2 3C-like protease (3CLpro) suppressor in recent
molecular docking studies and in silico assessment of herbal medicines. It has been demonstrated that
quercetin increases the expression of heme oxygenase-1 through the nuclear factor erythroid-related factor
2 (Nrf2) signal network. Inhibition of heme oxygenase-1 may increase bilirubin synthesis, an endogenous
antioxidant that defends cells. When human gingival fibroblast (HGF) cells were exposed to lipopolysaccharide
(LPS), inflammatory cytokine production was inhibited. The magnesium (Mg+2) cation
complexation improves quercetin free radical scavenging capacity, preventing oxidant loss and cell death.
The main objective of this paper is to provide an overview of the pharmacological effects of quercetin, its
protective role against SARS-CoV-2 infection, and any potential molecular processes.

Expansive clay soil has high potential of swelling due to minerals content which bind water, therefore, soil improvement is required to stabilize the swelling behavior by add binder additive such as lime in deep soil mixing method (DSM). In this study, Finite Element model approach was performed with embankment provided on the top of expansive clay layer to provide bearing layer for road construction. As the deep soil mixing is applied on the subgrade (expansive clay layer), some model variation is performed such as diameter variation with 0.4m; 0.6m; 0.8m, depth variation with 5m; 6.5m; 8m and space variation 0.8 m;1.2m;1.6m; 2.4m. Area ratio parameter also used for ease understanding of deep soil mixing behavior with so many model variations provided. Analysis results shows that higher area ratio of deep soil mixing will provide lower displacement value either immediate displacement or consolidation displacement. Moreover, plot result of area ratio shows that area ratio of 0.4 provide effective value regarding consolidation displacement and duration.

Published: November 2022

Background

Multimorbidity has become a new challenge for medical systems and public health policy. Understanding the patterns of and associations among multimorbid conditions should be given priority. It may assist with the early detection of multimorbidity and thus improve quality of life in older adults.

Objective

This study aims to comprehensively analyze and compare associations among multimorbid conditions by age and sex in a large number of middle-aged and older Chinese adults.

Methods

Data from the home pages of inpatient medical records in the Shenzhen National Health Information Platform were evaluated. From January 1, 2017, to December 31, 2018, inpatients aged 50 years and older who had been diagnosed with at least one of 40 conditions were included in this study. Their demographic characteristics (age and sex) and inpatient diagnoses were extracted. Association rule mining, Chi-square tests, and decision tree analyses were combined to identify associations between multiple chronic conditions.

Results

In total, 306,264 hospitalized cases with available information on related chronic conditions were included in this study. The prevalence of multimorbidity in the overall population was 76.46%. The combined results of the 3 analyses showed that, in patients aged 50 years to 64 years, lipoprotein metabolism disorder tended to be comorbid with multiple chronic conditions. Gout and lipoprotein metabolism disorder had the strongest association. Among patients aged 65 years or older, there were strong associations between cerebrovascular disease, heart disease, lipoprotein metabolism disorder, and peripheral vascular disease. The strongest associations were observed between senile cataract and glaucoma in men and women. In particular, the association between osteoporosis and malignant tumor was only observed in middle-aged and older men, while the association between anemia and chronic kidney disease was only observed in older women.

Conclusions

Multimorbidity was prevalent among middle-aged and older Chinese individuals. The results of this comprehensive analysis of 4 age-sex subgroups suggested that associations between particular conditions within the sex and age groups occurred more frequently than expected by random chance. This provides evidence for further research on disease clusters and for health care providers to develop different strategies based on age and sex to improve the early identification and treatment of multimorbidity.

To present the experience in clinical/radiological diagnosis and treatment of sigmoid volvulus. Cases with symptoms suggestive of intestinal obstruction secondary to sigmoid volvulus were included. The risk factors were: male sex, longer hospital stay, age over 70 years and the classic triad. Imaging studies were conclusive, with abdominal radiography and simple abdominal tomography being the tests of choice for the diagnostic approach. Sigmoid volvulus has a predictable clinical-radiological pattern, a thorough physical examination and first-line cabinet studies can be conclusive. The therapeutic option for these patients was surgery. Key words: Sigmoid; volvulus; diagnosis; treatment.
Impact of IoT on Supply Chain Performance
Authors: Monsreal Mario M , Carmona Benitez Rafael Bernardo
Published: November 2022

Purpose: To increase the understanding of the IoT by demonstrating its impacts and benefits on supply chain performance.

Design/methodology/approach: System dynamic simulation modeling to estimate IoT impacts on supply chain performance, based on a previously proposed framework and its propositions.

Findings: In general, simulation results show a positive impact on the supply chain activities where the propositions targeted. Specifically:

P2: better decision-making. – The study case shows better asset utilization, and reduced shipping time. However, transportation costs increase because of the lack of a decision-making system.

P3: enhanced supply chain connectivity/collaboration/integration. – The study case shows that benefits of supply chain integration through demand planning can be obtained.

P5: reduced lead-time. – The study Case shows a reduced shipping time when location technology and when all technologies are combined.

P6: better asset utilization. – The study Case shows a higher utilization factor, hinting a better asset utilization even without a decision-making system.

Research limitations/implications: The models here presented are based on merged data from different sources: Primary and secondary sources, and estimates based on assumptions. The mere nature of the base-data limits the precision of results.

Practical implications: The implementation of data collection or data transmission technologies alone is not sufficient to obtain full benefits. A decision-making processing system, that integrates the complete array of appropriated technologies, should also be implemented. This the underlying concept and the contribution of the IoT.

Published: November 2022

Abstracts: The application of topology in molecular graph and drug design is covered in this article. On the basis of the most recent developments in this area, an overview of the use of topological indices (TIs) in the process of drug design and development is provided. The introduction of concepts used in drug design and discovery, graph theory, and topological indices is the primary goal of the first section of this book. Researchers can learn more about the physical characteristics, chemical reactivity, and biological activity of these chemical molecular structures by using topological indices. In order to compensate for the lack of chemical experiments and offer a theoretical foundation for the production of medications and chemical materials, topological indices on the chemical structure of chemical materials and drugs are studied. In this article, we concentrate on the family of smart polymers that are frequently utilised in the production of drugs

Water isotopes in Mexican tap water
Authors: Ammer Saskia , Bowen Gabriel , Davies Gareth
Published: November 2022

Water isotope analyses can be used as tracers in water resource
sustainability, forensics (e.g. human, ecological, food authenticity and
provenance) and climate research, however, limited research has been
conducted on water in Mexico. This first national-level tap water survey
of coupled H-O isotope ratios is reported from over 50 cities and towns
across Mexico. Tap water across the country records a range of 82.4‰ for
δ2H and 12.0‰ for δ18O, analyzed using a Picarro L2130-i analyzer. The
isotopic values show strong relationships (r > 0.5) with
the geography as well as some social and socioeconomic parameters. A
Geographic Information System approach is used to develop maps of
predicted tap water isotope ratios (isoscapes) for Mexico. These
isoscapes will be useful to researchers interested in human-hydrological
systems as well as forensic scientists establishing the region of origin
or the travel history recorded by human remains.
Religion versus Politics: An Age-Old Question with Continued Importance to the U.S. Nonprofit Classification System
Authors: Camp Julia M. , Masselli John J. , Yurko Amy J. N.
Published: November 2022

IRC § 501(c)(3) grants federal tax exemption to nonprofit organizations, such as public charities, private foundations, and private operating foundations. Religious organizations classified as churches receive added preferential treatment, specifically, exemption from certain filing requirements and statutory audit protection through § 7611. Section 527 grants most political organizations tax-exempt status, although they are subject to tax on some income, are not exempt from filing requirements, and do not receive tax-deductible donations. This extreme disparity in treatment may incentivize political organizations to reconfigure their missions and organizational structures to meet the litmus test for classification as a church. After the awarding of church status to some seemingly politically charged organizations, we investigate this issue and propose that it is time for the U.S. Congress and the Internal Revenue Service to revisit, evaluate, and revamp the existing system to prevent political organizations from abusing the tax provisions intended to benefit churches.
Internal Governance and Cost Stickiness
Authors: Zhang Bo , Yang Limei , Zhou Ruixue
Published: November 2022

Internal governance is the bottom-up governance mechanism within the top management team (hereinafter referred to as “TMT”) through which key subordinates internally monitor the Chief Executive Officer (CEO). We find that cost stickiness is negatively associated with internal governance after controlling for legitimate economic reasons of cost stickiness, suggesting that internal governance mitigates agency-based cost stickiness. Consistent with the agency explanation, the results show that the impact of internal governance on cost stickiness is stronger for firms with lower future-value creation of selling, general, and administrative (SG&A) costs. In addition, we document that the impact of internal governance on cost stickiness is more pronounced for firms with more-effective board monitoring. This paper extends a growing literature that investigates the impact of internal governance on corporate decisions and complements existing studies on the role of various governance mechanisms in mitigating agency-based cost stickiness.
