Reconstructing financial analysis courses in higher vocational education in China: a factor analysis approach
Authors: Yan Weiwei , Sun Pengge 
Published: September 2023

Background: The development of information technology has had a significant impact on traditional financial analysis. For large amounts of data and complex business environments, financial analysts are required to use technical analysis tools to process mass data and deeply integrate financial analysis and enterprise value to enhance the competitiveness of enterprises. This requires the reconstruction of the financial analysis courses in higher vocational education in China. This manuscript studies the problems existing in traditional financial analysis courses and reconstructs these. Methods: A factor analysis approach is adopted to reconstruct the financial analysis courses. We study these courses from three perspectives — coursebooks, teachers, and teaching methods. We collected the data of relevant courses from online platforms in China and used content analysis to find the problems existing in the three areas. Results: The authors found that the content of the coursebooks were incomplete and outdated, the teachers lacked practical ability and were unaware of data analysis tools. Furthermore, their teaching methods were inefficient. Conclusions: The study reconstructs the financial analysis courses based on three aspects. First, the contents are supplemented with enterprise strategy, macro-environment analysis, industry analysis, business analysis, and the application of data analysis tools. Second, the teachers can work in the company to develop their vocational skills, and participate in training programs to learn data analysis tools. Third, the teaching methods can be dynamic and dual-purpose by cooperating with enterprises to enrich practical teaching. Furthermore, colleges and enterprises can make enterprise work a teaching task, develop simulation training platforms, and provide vocational skill grade certificates.
Morphometry of pyramidalis muscle and its role in reconstructive surgeries: A cadaveric study in South Indian population
Authors: Sumalatha Suhani , Rao Sharanya , Ankolekar Vrinda Hari 
Published: September 2023

Background: The pyramidalis muscle is a tiny triangular-shaped muscle that is located in the anterior abdominal wall, which originates from the body of the pubis and pubic symphysis and is inserted into linea alba. This study aimed to measure the different parameters of the pyramidalis muscle in adult cadavers. Methods: This study was carried out on 31 adults (26 males and five females) 10% formalin embalmed cadavers of both sexes from the Department of Anatomy at Kasturba Medical College, Manipal. Results: The mean length of the right pyramidalis muscle was 64.44 ± 12.52 mm and the left pyramidalis muscle was 64.73 ± 12.81 mm. The mean width of the muscle was 15 ± 4.18 mm and 15.03 ± 3.52 mm on the right and left sides, respectively. The mean thickness of the muscle was 1.32 ± 0.55 mm and 1.4 ± 0.80 mm on the right and left sides, respectively. The distance between the umbilicus to pubic symphysis ranged from 130–192 mm and their mean was calculated to be 159.77 ± 15.36. The distance between the umbilicus and the apex of the muscle ranged from 72–123 mm. Conclusions: The measured parameters like length, width and thickness may help the surgeons to locate the muscle during infra umbilical surgeries.
The Investment Development Path theory: Evidence from developing countries’ agricultural sector
Authors: Djokoto Justice Gameli , Agyei-Henaku Kofi Aaron A-O , Badu-Prah Charlotte 
Published: September 2023

Background: We examined the investment development path (IDP) through the perspective of developing countries’ agricultural sector. Our analytical approach indirectly accounts for interactions among countries regarding cross-border resource transfers. Aside from providing knowledge on testing the IDP by inferential statistics, the information would be relevant for policymaking. Identifying the stage(s) in the IDP not only highlights the global appeal of agriculture but also guides firms seeking to expand beyond borders. This information is essential for developing an effective economic strategy. Methods: We employed data from 1991 to 2021 for 55 countries from the Food and Agriculture Organization Corporate Statistical Database (FAOSTAT) and applied a fixed effects estimator corrected for serial correlation and non-constant variances. Results and conclusions: We found that agriculture in developing countries is currently in stages I and II of the IDP. Broadly, agricultural production requires policies that would increase outward foreign direct investment and inward foreign direct investment. Domestic agricultural businesses in developing countries must develop capacity by learning from foreign multinationals. This would enable agricultural businesses to invest abroad. Such a move would lead to an increase in outward FDI. As this would have resulted from increased GDP per capita, it will lead to movement from the existing stage to higher ones.
Violence in the Education: The Post-Revolutionary Situation in Hungary (1956-1957)
Authors: Somogyvári Lajos 
Published: September 2023

Background: The author attempts to introduce an unusual approach towards schools, universities, and dormitories, including their users (professors, teachers, parents, and students): How can the educational issues be seen through the lenses of special police forces in a specific historical moment? After the 1956 Hungarian revolution, a brutal pacification process took place all over the country, supported by the Soviet troops and special armed forces, police battalions of the restarting communist power. Methods: In this historical study, I used mainly military archive documents to show the perspective of the communist restauration and confront their viewpoints with party reports and some oral histories by eyewitnesses, who suffered several injuries during the repression. The paper is based on narrative analysis, as the official explanation presented various stories to justify their actions, while the reality in the background might be very different from this. Results: Between November 1956 and May 1957, these soldiers or officers became a familiar image in educational institutions. They blamed teachers and professors for misleading their students and thus creating a narrative of the counter-revolution of October 1956, while they identified themselves as parents or teachers (instead of the real ones, who lost their rights to do this, due to the participation in the revolution). Conversely, physical and verbal aggression was a widespread routine of the army officers. Conclusions: In extraordinary situations, during historical crises violence became suddenly real, allowed, and/or supported by many political actors to achieve their goals. After the consolidation of power, these special army and police forces were released and their activities were stopped by the authorities of the Ministry of National Defence because their presence was realized as an uncomfortable situation for the politicians. Such studies may give lessons us to learn, about how these scenes escalate into a point of no return.
Correlations between components of the immune system
Authors: Shabat Yehudit , Ilan Yaron 
Published: September 2023

Background: No evidence of the possibility to alter a constituent of the immune system without directly affecting one of its associated components has been shown yet. Methods: A schematic model was developed in which two triggers, fasting and splenectomy, were studied for their ability to affect the expression of cell membrane epitopes and the cytokine secretion of out-of-body autogeneic and syngeneic lymphocytes. Results: Fasting decreased expression of CD8 and CD25 and increased TNFα levels. The effect of splenectomy as a trigger was investigated in non-fasting mice by comparing splenectomized and non-splenectomized mice. An increase in the CD8 expression and in TNFα, IFNg, and IL10 secretion was noted. The effect of splenectomy as a trigger was investigated in fasting mice by comparing splenectomized and non-splenectomized mice. Splenectomy had a significant effect on expression of CD25 and CD4 CD25 and on secretion of TNFα, IFNg, and IL10. To determine the effect of keeping the cells in an out-of-body location on the expression of lymphocyte epitopes, tubes kept on top of the cages of the fasting mice were compared with tubes kept on top of empty cages. A significant change in the CD8 expression was noted. To determine the effect of keeping cells in an out-of-body location on cytokine secretion, tubes kept on top of cages were tested for cytokine levels. A significant decrease was noted for the secretion of TNFα and IFNg. Conclusions: The data obtained from this study characterized a system for induction of correlations between two components of the immune system without a transfer of mediators. The study showed that a mouse could affect cells at a distance and alter the expression of surface markers and cytokine secretion following two types of triggers: fasting and/or splenectomy. Thus, an out-of-body correlation can be induced between two components of the immune system.

Published: September 2023

Construction projects are constantly threatened by delays and cost overruns that might compromise their viability. Th us, identifying the leading causes of these issues based on the experience of experienced professionals is essential to planning and reducing these risks. This research evaluates the frequency and severity of variables causing delays and cost overruns in Colombian Caribbean Region road projects. Th e nine causes studied in this research were defined through a literature review, preliminary discussion and a pilot test. A survey directed to 42 road construction engineers allowed the authors to characterise these professionals’ perceptions regarding the frequency and severity of these variables in terms of delay and cost overruns, with a confi dence level of 80%. Statistical analyses were applied to the results of the survey to establish which variables generate the most signifi cant impacts when building roads and related works in the Colombian Caribbean Region
Partisan Return Gap: The Polarized Stock Market in the Time of a Pandemic
Authors: Sheng Jinfei , Sun Zheng , Wang Wanyi 
Published: September 2023

Using two proxies for investors’ political affiliation, we document sharp differences in stock returns between firms likely dominated by Democratic investors (blue stocks) and those dominated by Republican investors (red stocks) during the COVID pandemic. Red stocks have 20 basis points higher risk-adjusted returns than blue stocks on COVID news days (Partisan Return Gap). Lockdown policies, COVID cases, industry and firm fundamentals only explain at most 40% of the return gap. Polarized political beliefs about COVID, revealed through people’s social distancing behavior, contribute to about 40% of the return gap beyond the fundamental channel. Our paper provides partisanship as a novel aspect in understanding abnormal stock returns during the pandemic. This paper was accepted by Lukas Schmid, finance.

Published: September 2023

BackgroundDespite decades of calls for increased diversity in the health research workforce, disparities exist for many populations, including Black, Indigenous, and People of Color individuals, those from low-income families, and first-generation college students. To increase representation of historically marginalized populations, there is a critical need to develop programs that strengthen their path toward health research careers. High school is a critically important time to catalyze interest and rebuild engagement among youth who may have previously felt excluded from science, technology, engineering, and mathematics (STEM) and health research careers.MethodsThe overall objective of the MYHealth program is to engage high school students in a community-based participatory research program focused on adolescent health. Investigators will work alongside community partners to recruit 9ththrough 12thgraders who self-identify as a member of a group underrepresented in STEM or health research careers (e.g., based on race and ethnicity, socioeconomic status, first generation college student, disability, etc.). MYHealth students are trained to be co-researchers who work alongside academic researchers, which will help them to envision themselves as scientists capable of positively impacting their communities through research. Implemented in three phases, the MYHealth program aims to foster a continuing interest in health research careers by developing: 1) researcher identities, 2) scientific literacy, 3) scientific self-efficacy, and 4) teamwork and leadership self-efficacy. In each phase, students will build knowledge and skills in research, ethics, data collection, data analysis, and dissemination. Students will directly collaborate with and be mentored by a team that includes investigators, community advisors, scientific advisors, and youth peers.DiscussionEach year, a new cohort of up to 70 high school students will be enrolled in MYHealth. We anticipate the MYHealth program will increase interest and persistence in STEM and health research among groups that have been historically excluded in health research careers.

Authors: Liu Yang , Xie Lang , Wang Dingxue , Xia Kaide 
Published: September 2023

ObjectiveSuccessful prognosis is crucial for the management and treatment of osteosarcoma (OSC). This study aimed to predict the cancer-specific survival rate in patients with OSC using deep learning algorithms and classical Cox proportional hazard models to provide data to support individualized treatment of patients with OSC.MethodsData on patients diagnosed with OSC from 2004 to 2017 were obtained from the Surveillance, Epidemiology, and End Results database. The study sample was then divided randomly into a training cohort and a validation cohort in the proportion of 7:3. The DeepSurv algorithm and the Cox proportional hazard model were chosen to construct prognostic models for patients with OSC. The prediction efficacy of the model was estimated using the concordance index (C-index), the integrated Brier score (IBS), the root mean square error (RMSE), and the mean absolute error (SME).ResultsA total of 3218 patients were randomized into training and validation groups (n = 2252 and 966, respectively). Both DeepSurv and Cox models had better efficacy in predicting cancer-specific survival (CSS) in OSC patients (C-index >0.74). In the validation of other metrics, DeepSurv did not have superiority over the Cox model in predicting survival in OSC patients.ConclusionsAfter validation, our CSS prediction model for patients with OSC based on the DeepSurv algorithm demonstrated satisfactory prediction efficacy and provided a convenient webpage calculator.
Complete continuum of maternity care and associated factors among mothers who gave birth in the last twelve months in Mekane Selam town North-East Ethiopia: A community-based cross-sectional study,2021
Authors: Mengistie Hibist Tilahun , Belay Mengistu Abate , Sendekie Abrham Debeb , Shitie Anguach , Sewyew Dagne Addisu 
Published: September 2023

Background
Complete continuum of maternity care has significant value in improving the health and wellbeing of mothers and newborns. Assessing the complete continuum of maternity care is a global priority, particularly in developing countries. Despite the fact that the complete continuum of maternity care prevents more than half of all maternal and neonatal deaths, Ethiopia remains one of the largest contributors to the global burden of maternal and neonatal deaths due to the low implementation of the complete continuum of maternity care. Thus, this study aimed to assess the coverage of the complete continuum of maternity care and associated factors among mothers who gave birth in the last 12 months in the study area.

Methods
A community-based cross-sectional study with a multistage sampling technique was conducted among 479 mothers who gave birth in the last 12 months in Mekane Selam town. Data were collected from September 1 to November 30/2021 using an interviewer-administered questionnaire. Binary logistic regression analysis was computed. In multivariable logistic regression analysis, an adjusted odds ratio (AOR) with a 95% confidence interval (CI) and a P- value< 0.05 were used to identify significantly associated factors.

Results
The coverage of a complete continuum of maternity care was 42.4% (95% CI: 37.9%, 47%). Respondents with higher educational status (AOR = 4.17, 95% CI: 1.52, 11.44), pre-pregnancy contraception utilization (AOR = 3.53, 95% CI: 1.80, 6.92), planned pregnancy (AOR = 2.97, 95% CI: 1.27, 6.97) and early initiation of antenatal care (AOR = 4.57, 95% CI: 2.86, 7.31) were significantly associated with complete continuum of maternity care.

Conclusion
The coverage of complete continuum of maternal care was low in the study area. The coverage could be expanded by making the necessary interventions on the associated factors. It is essential for women to acquire education, utilize contraception, plan their pregnancies, and begin antenatal care at an early age in order to enhance the coverage of complete continuum of maternity care.

Published: September 2023

Background
Left-sided breast cancer patients receiving adjuvant radiotherapy are at risk for coronary artery disease, and/or radiation mediated effects on the microvasculature. Previously our laboratory demonstrated in canines with hybrid 18FDG/PET a progressive global inflammatory response during the initial one year following treatment. In this study, the objective is to evaluate corresponding changes in perfusion, in the same cohort, where resting myocardial blood flow (MBF) was quantitatively measured.

Method
In five canines, Ammonia PET (13NH3) derived MBF was measured at baseline, 1-week, 1, 3, 6 and 12-months after cardiac external beam irradiation. MBF measurements were correlated with concurrent 18FDG uptake. Simultaneously MBF was measured using the dual bolus MRI method.

Results
MBF was significantly increased at all time points, in comparison to baseline, except at 3-months. This was seen globally throughout the entire myocardium independent of the coronary artery territories. MBF showed a modest significant correlation with 18FDG activity for the entire myocardium (r = 0.51, p = 0.005) including the LAD (r = 0.49, p = 0.008) and LCX (r = 0.47, p = 0.013) coronary artery territories.

Conclusion
In this canine model of radiotherapy for left-sided breast cancer, resting MBF increases as early as 1-week and persists for up to one year except at 3-months. This pattern is similar to that of 18FDG uptake. A possible interpretation is that the increase in resting MBF is a response to myocardial inflammation.
On the impact of urban planning in contexts with limited enforcement of building and planning regulations: A study of the urban form of planned and unplanned informal settlements in Maputo, Mozambique
Authors: Mottelson Johan 
Published: September 2023

Background
More than one billion people live in informal settlements under precarious conditions. Urban planning is considered an important instrument to mitigate compromised living conditions in informal settlements. However, limited studies have investigated the long-term impact of urban planning in contexts with limited capacity to enforce building and planning regulations. The purpose of this study is to assess the long-term impact of urban planning on the development of sustainable urban form in contexts characterized by unregulated urban development.

Methods
The study conducted geospatial surveys of three urban areas in Maputo, Mozambique covering adjacent planned and unplanned settlements that were established more than 40 years ago and subsequently developed with limited enforcement of building and planning regulations. High-resolution maps were produced and six urban form metrics were computed for the planned and unplanned areas respectively, providing the basis for quantitative and qualitative comparative analysis.

Results
Although the study found signs of street encroachment and appropriation of the public space in the planned areas, the study found higher levels of built densities, higher proportions of public space, and higher average street widths in all planned areas compared to the respective neighboring unplanned areas. Furthermore, the statistical analysis consistently showed large effect sizes (Cohen’s d > 0.8) of urban planning on indicators of compact city development and access conditions.

Conclusion
The results underscore that planning of street fabrics and plot layouts can enhance compact city development, improve transportation conditions, and increase the feasibility of investments in infrastructure in contexts with limited capacity to administer the urban growth.

Published: September 2023

Background
Machine learning algorithms used to classify cystic renal masses (CRMs) nave not been applied to unenhanced CT images, and their diagnostic accuracy had not been compared against radiologists.

Method
This retrospective study aimed to develop radiomics models that discriminate between benign and malignant CRMs in a triple phase computed tomography (CT) protocol and compare the diagnostic accuracy of the radiomics approach with experienced radiologists. Predictive models were established using a training set and validation set of unenhanced and enhanced (arterial phase [AP] and venous phase [VP]) CT images of benign and malignant CRMs. The diagnostic capabilities of the models and experienced radiologists were compared using Receiver Operating Characteristic (ROC) curves.

Results
On unenhanced, AP and VP CT images in the validation set, the AUC, specificity, sensitivity and accuracy for discriminating between benign and malignant CRMs were 90.0 (95%CI: 81–98%), 90.0%, 90.5% and 90.2%; 93.0% (95%CI: 86–99%), 86.7%, 95.2% and 88.3%; and 95.0% (95%CI: 90%-100%), 93.3%, 90.5% and 92.1%, respectively, for the radiomics models. Diagnostic accuracy of the radiomics models differed significantly on unenhanced images in the training set vs. each radiologist (p = 0.001 and 0.003) but not in the validation set (p = 0.230 and 0.590); differed significantly on AP images in the validation set vs. each radiologist (p = 0.007 and 0.007) but not in the training set (p = 0.663 and 0.663); and there were no differences on VP images in the training or validation sets vs. each radiologist (training set: p = 0.453 and 0.051, validation set: p = 0.236 and 0.786).

Conclusions
Radiomics models may have clinical utility for discriminating between benign and malignant CRMs on unenhanced and enhanced CT images. The performance of the radiomics model on unenhanced CT images was similar to experienced radiologists, implying it has potential as a screening and diagnostic tool for CRMs.
