Authors: Lalani Bishakha , MR Samrat , R Purushottam , Teja K K Viswa
Published: April 2023

Management of endodontic mishaps is challenging for operator. Perforation of the root in the course of access cavity preparation is commonly encountered in modern practice. The prognosis of teeth with root perforations depends on several factors, including size, location, time since occurrence and rapidity of sealing the perforation area with biocompatible material. Root perforations are clinical situations that can be solved by either nonsurgical or surgical approach­es using different biocompatible materials. The purpose of this case report is to describe a successful repair of a long‑standing iatrogenic coronal root perforation in a maxillary right central incisor solved surgically using Biodentine (Septodont, Saint-Maur-des-Fossés, France) which was able to induce new bone formation and re-establish gingival and periodontal health status.

Published: April 2023

Esta nueva edición de Introducción a la epidemiología representa una valiosa oportunidad para actualizar el diálogo con otros campos científicos frente al escenario científico contemporáneo. La epidemiología se ha constituido en una importante disciplina científica, esencial para todas las ciencias clínicas, base de la medicina y de otras formaciones profesionales en salud. Desde sus inicios en el siglo XIX, la epidemiología ha revelado una fuerte vocación de ciencia aplicada, dirigida hacia la solución de los problemas de salud. Se trata, sin duda, de una poderosa herramienta científica de gran utilidad para el área de la salud, justamente por su carácter pragmático. Hoy la ciencia epidemiológica continúa ampliando su importante papel en la consolidación de un saber científico sobre la salud humana, su determinación y consecuencias, y subsidiando ampliamente las prácticas de salud. En ese sentido, además de reforzar su aspecto metodológico derivado de una metodología pragmática y su proyecto de interactividad, que lo torna cada vez más directo y objetivo, buscamos revisar principalmente los aspectos conceptuales de los modelos de salud-enfermedad. De ese modo, pretendemos realzar las posibilidades de la disciplina epidemiológica con el fin de poder actuar en el contexto del movimiento contemporáneo de promoción de la salud.

Filozoficzne trudności teorii interesariuszy

Philosophical difficulties of stakeholder theory – which plays an important role in
CSR and business ethics – are connected first of all with questions of its status and
justification. What sense does stakeholder theory have: descriptive, instrumental or
normative? And if normative, why then should executives worry about multiple
stakeholder demands?
It is well known that Freeman, one of the most important authors of stakeholder
theory, deliberately disregarded these problems. In philosophical questions he invoked
Rorty’s pragmatism, which in his opinion effectively undermined the “positivistic”
dichotomy between facts and values, science and ethics, and enabled stakeholder
theory to be understood at the same time as both descriptive and normative.
The article presents some difficulties connected with this view, focusing on its
dubious assumptions and unfavourable consequences. To the assumptions belongs
a false dilemma taken from Rorty, which states that knowledge follows either a rule
of representation or a rule of solidarity. One of the unfavourable consequences is
the conclusion that stakeholder theory may be true only if its followers are able to
force the stakeholders to accept its truthfulness.
The main thesis of the article says that, as a result of pragmatic justification,
stakeholder theory became a sort of arbitrary narration, which is unable to deal with
its (empirical) misuses. However, a return to a more traditional view on facts and
values enables us to appreciate the descriptive advantages of the theory and to identify
difficulties connected with its normative layer. From this point of view, the
attempt at a pragmatic interpretation of stakeholder theory was a misunderstanding
that should be withdrawn from circulation.

THE ROLE OF STRENGTH TRAINING IN PREVENTING MUSCULOSKELETAL INJURIES AMONG FEMALE AND MALE SOCCER PLAYERS
Authors: Zduński Szymon , Grygorowicz Monika
Published: April 2023

Introduction The occurrence of sports injuries among soccer players causes both financial and health losses, which is why preventing them is crucial. Science should provide reliable data on how different interventions affect the occurrence of sports injuries among athletes. Aim The review aims to analyse the quality of evidence proofed by the studies on the effectiveness of strength training in preventing sports injuries in soccer players. Material and methods Five databases were used in the review: Web of Science, Embase, Cochrane Library, Academic Search Ultimate, and Pubmed. Keywords used included: soccer players, strength training, hypertrophy training, protocol, injury rate, burden, and prevalence. Quality evaluation of studies found was performed using PEDro scale. Results Of the 646 studies researched, only 4 met the criteria of being applicable to this systematic review. Conclusions All four studies confirmed the decrease in the number of injuries and absence days per 1000h of exposure due to strength training; nonetheless, the lack of standardized protocol based on knowledge efficient at building strength makes the conclusion unreliable.
PROOF OF VALUE OF ANTERIOR GLENOHUMERAL INSTABILITY TECHNIQUES

Published: April 2023

ABSTRACT Arthroscopic Bankart and Coracoid Transfer are the most common procedures. Results of Bankart technique differ depending on the surgeon’s experience (type of anchors used, qualification, long learning curve). Performing Arthroscopic Bankart may be effective when there is minimal bone loss (< 10–15%), good soft tissue (no ALPSA) and ISIS < 3. With these assumptions long term recurrence rate (RR) can be stated as 8%. Adding of remplissage improves RR to 3–6%, which is comparable to Latarjet with RR 4.4–6%. Coracoid transfer has advantage of being quicker, safer and cheaper. It must be underlined that this type of surgery is effective for patients with risk factors (probably regardless risk). Moreover, we assume that good function and satisfaction level with high return to sport (85%) is associated with this intervention. Still some issues remain like frequent complications (mostly temporary) like apprehension or residual pain. Learning curve is also not in favor of this technique. Yet it is difficult to conclude whether Arthroscopic Bankart or Coracoid Transfer are superior. Free bone block has comparable results to Latarjet, with the main problem being donor side complication in autografts. Open Bankart also do not stand out of Coracoid Transfer
LATARJET PROCEDURE FOR ANTERIOR SHOULDER INSTABILITY – THERE IS NO REASON TO ABANDON SCREWS
Authors: Laprus Hubert , Brzóska Roman
Published: April 2023

Introduction Latarjet is a widely performed procedure for anterior shoulder instability. It can be performed open or arthroscopic and with conventional screw fixation (SF) or suture button (SB). The aim of this review is to compare the two techniques to answer the question: is there any reason to abandon the screws? Results Traditional open Latarjet with SF has follow-up longer than 20 years and recurrence rate reported on 5.9% with rate of developing osteoarthritis (OA) reported on 20%, but only 1.5% of graft pseudoarthrosis. Arthroscopic Latarjet in mid-term FU resulted in no recurrence of dislocations and 93.5% return to sport rate. However, 10 of 64 (15.6%) patients had revision surgery, most common removal of prominent screw. Short-term results after arthroscopic SB proved efficiency of this type of fixation. Recurrence of instability after SB fixation was observed in 3% (4 of 136), healing rate was 95% (115 of 121 patients) and 3 of 136 patients required revision procedure, because of instability recurrence. Conclusion Clinically SB demonstrated similar functional outcome and ROM when compared to SF with the potential benefit of lower rates of graft resorption and hardware related complications. However, rate of instability recurrence was higher for SB technique.
Poder, intensidad del trabajo y crisis en un modelo marxista de ciclos endógenos
Authors: Cajas Guijarro John
Published: April 2023

Este trabajo reinterpreta algunas intuiciones de Marx mediante un modelo de ciclos endógenos en tres dimensiones: tasa de empleo, participación salarial e intensidad del trabajo (variable que no ha recibido suficiente atención en la literatura marxista de modelos cíclicos). El artículo demuestra analíticamente (mediante el teorema de bifurcaciones de Hopf) y con simulaciones la existencia de ciclos estables dentro del modelo, si la mecanización es suficientemente alta y el poder obrero de negociación salarial es menor a un determinado umbral. En cambio, el modelo es inestable cuando el poder de negociación obrero es demasiado alto, resultado que permite plantear la noción de crisis económica estructural, distinta a las crisis económicas periódicas del ciclo capitalista. Al final, se resumen los resultados y se sugieren posibles extensiones al modelo.
La significación del trabajo
Authors: Freyssinet Jacques
Published: April 2023

El debate social acerca de la cuestión del trabajo y de su valor se vuelve frecuentemente confuso debido a la polisemia de la noción tanto de trabajo como la de su valor. En lo referente a la primera, la gran variedad de los tipos de trabajo pone en relieve su indeterminación. Por su parte, la noción de valor cuando se aplica al trabajo, puede adoptar tres enfoques distintos: en cuanto modo de desarrollo personal y de socialización, el trabajo puede ser un valor fundador del ser humano (lo cual se aborda en la primera sección de este artículo); también se le puede reconocer como la fuente primaria de la producción de valores de uso (discutido en la segunda sección), y, en fin, se le puede insertar en la esfera mercantil, si bien es cierto que el trabajo no es una mercancía, la fuerza de trabajo se intercambia en las economías de mercado como si lo fuese (lo que se trata en la tercera sección).

Published: April 2023

ABSTRACT
This research aimed to examine the effect of institutional quality, financing growth, and earnings management on the stability of Islamic banks in Southeast Asia for the 2014-2021 period. The sampling technique used was purposive sampling and received 11 Islamic commercial banks from Brunei Darussalam, Indonesia, and Malaysia. Data sources were obtained from each bank’s financial statements and the World Bank’s statements. The analysis method used was panel data regression analysis with Eviews 12 software. The results showed that the quality of institutions and the growth of financing had a significant effect on the stability of banks proxied by the Z-Score. The quality of institutions has a positive influence, while the growth of financing has a negative effect on banks' stability. Furthermore, the variables of earnings management have no significant impact on the stability of the bank. This research was limited to a sample of countries in Southeast Asia, so it is expected to be a reference for improving the quality of institutions to support banking performance. The implications of this study are expected to be an evaluation for banks to pay more attention to their policies in financing expansion and improve the quality of financial statements to minimize earnings management practices whose existence does not affect bank stability.

ABSTRACTBackground: Pregnant women require calcium as a vital vitamin. Insufficient calcium intake during pregnancy can result in enamel hypoplasia and cavities in deciduous teeth. It can boost pregnant women's calcium intake with calcium-containing pill formulations and vitamin D; however, this has negative effects such as kidney stone issues. Salmon can be used as a substitute because it has no negative side effects and contains omega 3, which can enhance calcium absorption. Purpose: This study aimed to determine the effect of salmon (Salmo salar) consumption on calcium levels in the teeth of mice (Mus musculus). Method: This study used pregnant mice and a post-test-only control strategy. Pregnant mice were fed salmon combined with CMC (Carboxy Methyl Cellulose) and CMC (Carboxy Methyl Cellulose) alone as a control. The salmon dose administered is 2.17 mg/0.5 ml. Using atomic absorption spectrophotometry, mice dental calcium levels can be determined (AAS). Result: The findings of hypothesis testing with an unpaired t-test of 0.041 revealed a significant difference between the salmon-eating and CMC-consuming groups at p 0.05. (Carboxy Methyl Cellulose). Conclusion: Consuming salmon can significantly increase the calcium content of mouse teeth. Keywords: Dental calcium, Mice (Mus Musculus, Pregnant mice, Salmon (salmo nalar)

Published: April 2023

Introduction: Successful R0 resection is crucial for the survival of patients with primary liver cancer (PLC) or liver metastases. Up to date, surgical resection lacks a sensitive, real-time intraoperative imaging modality to determine R0 resection. Real-time intraoperative visualization with near-infrared light fluorescence (NIRF) using indocyanine green (ICG) may have the potential to meet this demand. This study evaluates the value of ICG visualization in PLC and liver metastases surgery regarding R0 resection rates. Materials and Methods Patients with PLC or liver metastases were included in this prospective cohort study. ICG 10mg was administered intravenously 24 hours before surgery. Real-time intraoperative NIRF visualization was made with the SpectrumTM Fluorescence Imaging Camera System. First, all liver segments were inspected with the fluorescence imaging system and intraoperative ultrasound for identification of the known tumor as well as additional lesions, compared to preoperative MRI. PLC, liver metastases, and additional lesions were then resected according to oncological principles. Of all resected specimens the resection margins were analyzed with the fluorescence imaging system for ICG positive spots right after resection. Histology of additional detected lesions as well as ICG fluorescence compared to histological resection margins were assessed. Results Of the 66 included patients median age was 65.5 years (IQR 58.7 - 73.9), 27 (40.9%) were female and 18 (27.3%) were operated laparoscopically. Additional ICG positive lesions were detected in 23 (35.4%) patients of which nine (29%) were malignant. In patients with no fluorescent signal at the resection margin, R0 rate was 93.9%, R1 rate was 6.1%, and R2 rate was 0% compared to a ICG positive resection margin with a R0 rate of 64.3%, R1 rate of 21.4%, and R2 rate of 14.3% (p=0.005). One and two year overall survival were 95.2% and 88.4%, respectively. Conclusion The here presented study provides significant evidence that ICG NIRF guidance helps to identify R0 resection intraoperatively. This offers a true potential to verify radical resection and improve patients´ outcome. Furthermore, implementation of NIRF guided imaging in liver tumor surgery allows to detect a considerable amount of additional malignant lesions.

Published: April 2023

The paper considers the modeling of uniaxial ionic ferroelectrics based on the Fokker-Planck equation. The equation is solved numerically using the stochastic analogue method. To describe the quasi-equilibrium state of a ferroelectric, a system of moments is constructed, which is closed using the Gaussian distribution and empirical dependence of critical temperature on key parameters. It is shown that the resulting system gives acceptable results on the problem of temperature hysteresis.

This study aims to determine the effect of the Collaborative Creativity (CC) learning model on students’ creative thinking skills on simple harmonic vibration material. We also examine the different responses by gender. This quantitative study used a quasi-experimental method with a nonequivalent pretest-posttest control group design. The sample used in this study was grade 10th, consisting of 32 students as the experimental class, and 30 as a control class. The research instrument used was a test of creative thinking skills. The results showed the average N-gain in the experimental class was 0.73 with a very high interpretation, and the control class was 0.32 with a moderate. The results of hypothesis testing using the two-way ANOVA test show a sig < 0.05, which means that the learning model influences students’ creative thinking skills. In addition, the CC learning model was also comfort to use by gender which statistical analysis prove the sig > 0.05, which means that there is no gender effect on students’ creative thinking skills. Thus the Collaborative Creativity (CC) learning model can be used as an alternative to improve students’ creative thinking skills on simple harmonic vibration material.
Newtonian Yoyo (Lato-Lato) Phenomenon in Indonesia: An Innovative Resource for IGCSE Physics Teaching and Learning?
Authors: Akhsan Hamdi , Putra Guruh Sukarno , Ariska Melly
Published: April 2023

This paper aims to stimulate a teaching and learning reflection for Indonesian IGCSE physics classrooms through a recent booming and recreational game of Newtonian yoyo called lato-lato. As physics is one of the critical and complex subjects in secondary school, it establishes a struggle for students to comprehend the concept of physics. The 21st-century physics education learning aims to promote high-end reasoning and deep understanding. Contextual physic learning will support this mission to reach maximum attainment for students. Physics through contextual knowledge will be more feasible for students. The recent phenomenon of lato-lato encounters a new interest for students. Lato-lato as a demonstrator and contextual example will be a resourceful material for several concepts of Newtonian mechanics, for instance: collision and energy. In addition, lato-lato may provide an advanced idea of circular motion, momentum, and impulse, oscillation. Lato-lato involvement may bring a chance for IGCSE curriculum adjustment in mechanics topics to become a significant pre-learning process. By using the adjusted curriculum, students are more likely to reach their maximum attainment and conceptual understanding of mechanics because students feel interested and encouraged to learn through a problem-solving and real-world setup. Lato-lato (Newtonian Yoyo) phenomenon may solve students’ learning difficulties in IGCSE physics through a conceptual phenomenon.
Evaluation of clinical pharmacist-led medication review in patients referred to a hospital-based residential aged care support service
Authors: Chan June , Bolitho Richard , Hay Karen , Yong Faith
Published: April 2023

Background

Hospital-based Residential Aged-care Support Service (RaSS) teams typically consist of doctors and nurses who provide emergency and hospital substitutive care to residents of residential aged care facilities (RACF). While evidence supports the role of community pharmacist-led medication reviews in RACFs, there is limited literature evaluating the role of pharmacists integrated into aged care support teams. The purpose of this study was to analyse the effect of RaSS pharmacist-led medication reviews on polypharmacy, drug burden index, potentially inappropriate medications and potential prescribing omissions for residents living in RACFs.

Methods

Residents were referred to a Residential Aged-care Support Service pharmacist for medication review over a 12-month period. Medication-related problems and recommendations identified by the pharmacist were communicated to the resident’s general practitioner and RaSS medical practitioner for review. Residents’ medication histories were obtained at baseline and at one-month post-intervention. The number of medications prescribed to RACF residents, their associated drug burden indices, potentially inappropriate medications, and potential prescribing omissions identified at baseline and post-intervention were compared to evaluate the effects of RaSS pharmacist-led medication reviews.

Results

175 residents with a mean age of 84 years were referred to a hospital-based Residential Aged-care Support Service pharmacist for medication review. Median time to post-intervention evaluation was 29 days. The mean total number of medications prescribed were reduced from 18 medications at baseline to 17 medications post-intervention (p<0.001). The mean drug burden index score was reduced from 1.53 (at baseline) to 1.35 post-intervention (p<0.001). There were more residents that experienced a decrease in inappropriate medications (p<0.001) and prescribing omissions (p=0.008) compared to those that had an increase.

Conclusions

This study suggests that medication reviews performed by pharmacists embedded in hospital-based residential aged care support services may improve medication use and prescribing practices in aged care. Future research needs to be prioritised to corroborate this.
Tailoring Elastic Scattering of Relativistic Antiferromagnetic
Domain Walls for Collision-based Computing
Authors: Otxoa Ruben M. , Tatara Gen , Roy Pierre E. , Chubykalo-Fesenko Oksana
Published: April 2023

Soliton-based computing relies on their unique properties for transporting energy and emerging intact from head-on collisions. Magnetic domain walls are often referred to as solitons disregarding the strict mathematical definition requiring the above scattering property. Here we demonstrate the conditions of elastic and inelastic scattering for spinorbit torque-induced dynamics of relativistic domain walls on the technologically relevant Mn2Au antiferromagnetic material. We show that even domain walls with opposite winding numbers can experience elastic scattering and we present the corresponding phase
diagram as a function of the spin-orbit field strength and duration. The elastic collision requires minimum domain walls speed, which we explain assuming an attractive potential
created by domain wall pair. On the contrary, when the domain walls move at lower speeds, their collision is inelastic and results in a dispersing breather. Our findings will be
important for the development of soliton-based computing using antiferromagnetic spintronics and we discuss their prospects for building NOT and XOR gates.
Repurposing Drugs for COVID-19 by Graph Convolutional Network
Authors: Yue Rongting , Dutta Abhishek
Published: April 2023

Computational approaches for drug repurposing speed up the process of finding drugs for fast-spreading diseases such as COVID-19, which is challenging due to unknown disease mechanisms and pathogens. Here we present a graph learning-based pipeline to identify the potential drugs that are likely to intervene in COVID-19 virus infection using RNA-seq data and molecular interactions and features. We do so by detecting disease-related genes and pathways first, then constructing a heterogeneous graph model that integrates protein-protein interactions, drug-protein interaction and drug-target interactions, and finally applying graph convolutional network on the graph model to predict potential drug molecules. With this method, we predict 28 drugs that have the potential to bind with disease-related proteins. Molecular docking shows that 2 drugs, Flunisolide and Adapalene, have a high possibility to be used for COVID-19 by stably binding with the products of disease-related genes STAT1 and AKT1, respectively, which will be later confirmed by experiments. The proposed method applies to drug repurposing for any diseases with gene expression data, and it is expected to expand our understanding of novel disease mechanisms and select drug candidates for therapy design.

Published: April 2023

Current regulatory tools are not well suited to address freshwater salinization in urban areas and the conditions under which bottom-up management is likely to emerge remain unclear. We hypothesize that Ostrom’s social-ecological-systems (SES) framework can be used to explore how current understanding of salinization might foster or impede its collective management. Our study focuses on the Occoquan Reservoir, a critical urban water supply in Northern Virginia, U.S., and uses fuzzy cognitive maps (FCMs) to characterize stakeholder understanding of the SES that underpins salinization in the region. Hierarchical clustering of FCMs reveals four stakeholder groups with distinct views on the causes and consequences of salinization, and actions that could be taken to mitigate it, including technological, policy, and governance interventions and innovations. Similarities and differences across these four groups, and their degree of concordance with measured/modeled SES components, point to actions that could be taken to catalyze collective management of salinization in the region.

Fabricating a functional heterogeneous interface to enhance the catalytic performance is quite significant for developing high-efficient electrocatalysts. Herein, we designed a coral-like Ni2P@CeO2 hybrid nanoarrays on nickel foam via selective-phosphorization of Ni(OH)2@CeO2. Benefiting from CeO2 as the “electron pump”, it leads to electrons transfer from Ni2P to CeO2 side, and induces the electrons redistribution in interface boundary, thereby optimizing the H* adsorption free energy in HER process. As proposed, owing to the superior affinity to oxygen-containing species of CeO2, the H2O molecule will preferentially adsorb on CeO2 side, and easily decompose into OH* and H* with lower energy barrier. Subsequently, benefiting from the lower H* adsorption free energy of P sites, the generated H* will transfer to Ni2P side through spillover process. Contributing to the synergistic effect of double-active sites, the Ni2P@CeO2/NF electrode exhibits brilliant catalytic performance for HER with 62 mV to attain 10 mA/cm2 and exceptional durability over 100 h in 1 M KOH solution under ~ 100 mA/cm2. Meanwhile, attributing to the similar interface electrons redistribution effect, the precursor Ni(OH)2@CeO2/NF also displays excellent OER electrocatalytic performance, it only requires 229 mV to arrive 10 mA/cm2, even better than benchmark RuO2. Hence, the assembled Ni(OH)2@CeO2/NF||Ni2P@CeO2/NF system only needs 1.53 V to achieve 10 mA/cm2 in basic solution. Moreover, the electrolyzer also presents brilliant electrocatalytic activity and stability in natural seawater alkaline electrolyte with higher reserves on earth. This research offers a novel insight to enhance the catalytic properties of TMPs materials for hydrogen production.

Multiple myeloma is the type of cancer that difficult to diagnosis early due to vague symptoms which can lead to misdiagnosis or create confusion with other diseases. When the symptoms are visible it may reach to advance cancer stage when even appropriate treatment is not left. This paper seeks and proposes a method for diagnosis of multiple myeloma through basic blood and urine tests by utilizing radar chart to increase readability and help to make rational decision making for patients and doctors. The radar chart is optimal way to visualizing numeric values. As a result of visualizing it as a graph, a clear visual and morphological difference was found compared to normal people.

Water chestnut (2n = 48) is an aquatic plant of Trapaceae family, the fruits of which are nutritious and have medicinal properties. By selecting from Green Spineless and Red Spineless Biotypes for high TSS and yield from natural population, we developed Improved Red Spineless (IRS) and Improved Green Spineless (IGS) genotypes and registered at N.B.P.G.R as IC 642169 and IC 642170, respectively. These two improved varieties were analyzed with the well-known local varieties using 10 RAPDs and 10 ISSR primers. A total of 78.0 polymorphic fragments with an average PIC of 0.32 and 0.16 and an average MI of 1.48 and 1.09 were produced by the RAPD and ISSR markers, respectively. The dendrogram analysis based on individual and combined RAPD and ISSR markers has demonstrated that the new improved varieties are molecularly distinct from the locally popular varieties. Among four genotypes, the unique gene sequences in 550 bp and 800 bp DNA ladders identified by AP-4 primer and 600 bp DNA ladders identified by AP-32 primer are only found in IRS genotype as dimorphic bands and single band, respectively. Similarly, in IGS water chestnut, DNA fragments AP30-1250, and ISSR23-1500 & ISSR23-1350 are only found as single bands and dimorphic bands, respectively.
The Burden of the Broken Grid: Modelling improved power-sector reliability to support low carbon development in Nigeria

Nigeria has one of the greatest electricity deficits globally and, even in areas connected to the central grid, struggles to provide reliable power across the nation. Frequent system collapses and widespread reliance on diesel generation present a burden for Nigerian households and the economy as a whole. One causal factor in these collapses is capacity inadequacy owing to reduced plant availability as plants are frequently non-operational due to maintenance or other management issues. While this dynamic has been established, it has not yet been explored in energy systems modelling as a potential barrier to meeting Nigeria’s decarbonization goals. Using a combination of OSeMOSYS and FlexTool modelling, this study shows that increasing available capacity decreases loss of load in the energy system. The resulting decrease in backup diesel generation nearly halves total system costs and emissions. Further, Nigeria is unable to meet its 2021 Nationally Determined Contributions (NDCs) without such improvements, indicating that increasing plant availability and reducing diesel generator use must be prioritized in policy to support national implementation of these targets.
Policy Insights:
1) Improved power plant availability can dramatically reduce CO2 emissions from the power sector, even under a business-as-usual scenario. However, increasing the pace of that improvement has a smaller impact on emissions.
2) Nigeria can meet its 2030 Unconditional NDC targets without significant changes to its generation mix if plant availability is improved. Near-term investments in energy efficiency will help to further ensure that targets are met.
3) Nigeria can meet its 2030 Conditional NDC targets with energy efficiency investments and improved plant availability.
4) A 30% cap on variable renewable energy (VRE) coupled with full plant availability is expected to reduce system collapses and lost loads. In the flexibility analysis, runs with full availability were able to reduce lost load even in scenarios with increased VRE.
5) It is not possible to meet long-term decarbonization goals without plant improvement.
Factors Affecting Capital Structure Decisions of Banks: A Systematic Review of Evidence from Commercial Banks of Ethiopia
Authors: Gofe Tesfaye Eresso , Seyoum Arega
Published: April 2023

The present systematic literature review aims to analyze the literature on factors affecting capital structure decisions of commercial banks in Ethiopia to identify the existing gaps and the level of existing research in the field and to provide direction for future research. The review was conducted using 11 relevant and available scholarly studies that were published in any time period, mainly using open search engines and databases because of the shortage of studies for the specified review and lack of access to the known database. Different key words were used to identify the articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework was employed to analyze the research work on capital structure decisions. The inclusion and exclusion criteria were specified in the review protocol. The descriptive analysis was performed based on different parameters to arrive at conclusions. A citation analysis was also performed to recognize impactful authors and papers. The findings revealed that most of the variables of interest explored in the studies contradicted each other and the previous literature variables. The capital structure research studies were conducted by considering few variables, and most of the studies were not cited. The findings regarding the theories supported by factors affecting the capital structure decisions of commercial banks in Ethiopia were contradictory and not justified. The banking literature still doesn't cover the capital structure of banks very much. There is currently a lack of clarity regarding how banks determine their capital structure and what variables affect their corporate financing behaviour. Therefore, it is recommended that the concerned body conduct an in-depth study of the decisions banks make about their capital structure by identifying pertinent elements.

Purpose To explore needs, expectations and experiences of asylum-seeking parents and unaccompanied minors on the initial health assessment for children and adolescents, and access to care upon entry in the Netherlands.Methods We conducted five semi-structured focus group discussions with asylum seeking parents and unaccompanied minor refugees, from Syria, Eritrea, Afghanistan and other middle-east and African countries, supported by professional interpreters. To triangulate findings, semi-structured interviews with health care professionals involved in care for refugee children were conducted. Transcripts of focus group discussions were inductively and deductively coded and content analysed, transcripts of interviews were deductively coded and content analysed.Results In total, 31 asylum seeking participants (23 parents of 101 children, 8 minors) and 6 healthcare professionals participated. Parents and minors expressed that upon entry, their needs were met for vaccinations, but not for screening or care for physical and mental health problems. Parents, minors and health professionals emphasized the necessity of appropriate information and education about health, diseases and the health system. Cultural change was mentioned as stressful for parent-child interaction and parental well-being.Conclusion The perspectives of refugee parents and unaccompanied minors revealed opportunities to improve the experience of and access to health care of refugees entering the Netherlands, especially risk-specific screening and more adequate education about health, diseases and the Dutch health care system.
