Climate-Related Trade Measures: Assessing Impacts for Bolivia, Colombia, Ecuador, and Peru
Authors: Cosbey Aaron , Vogt-Schilb Adrien
Published: August 2023

There is a growing wave of concern for the embodied carbon in traded goods. One manifestation of that concern is large economies such as the USA and the European Union enacting climate-related trade measures, including border carbon adjustment. This paper reviews more than ten climate-related trade measures that are currently enacted or under discussion globally and five initiatives from large companies to source low-carbon inputs. It then assesses Bolivia, Colombia, Ecuador, and Perus vulnerability to trade restrictions, based on estimated greenhouse gas intensity of their exported goods (using an input-output analysis) relative to other global producers, and an exposure analysis that assesses the likelihood that current importers of these products might implement climate-related trade measures. Finally, it reviews existing scenarios of global oil, natural gas and coal demand, and asks what they mean for fossil fuel exports from these countries. Agricultural goods stand out as vulnerable, as they are the main driver of deforestation and associated emissions. The most serious threat is the vulnerability of fossil fuel exports, primarily crude oil and gas, which dominate the four countries current exports. The paper exposes recommendations in terms of diversifying the economy away from fossil fuels and preparing exporters to comply with emerging climate-related trade restrictions.
Investigation of techniques to replace amalgamation in artisanal gold mining operations
Authors: Torkaman Pariya , Veiga Marcello , Lavkulich Leslie , Klein Bern
Published: August 2023

Artisanal gold mining is the leading source of anthropogenic mercury emissions worldwide. This article explores cost-effective gold leaching methods for skilled miners to address mercury's environmental and health impacts in this sector. A sample from Colombia's La Maria deposit, containing 48.87 ppm gold, ground to 80% below 0.13 mm, served as the basis for comparison. The standard whole ore amalgamation approach, commonly used by miners, resulted in less than 19% gold extraction. However, employing cyanidation with 1g/L of free cyanide extracted 84% of the gold within 24 hours. Among the unconventional processes investigated, using effluent from a local cassava processing plant as a lixiviant demonstrated promise. Two cassava varieties produced liquids with 267 and 600 mg/L of free cyanide, leading to 50.9% and 82.4% gold extraction from the ore in 24 hours, respectively. Another alternative method involved employing Dimethyl sulfoxide, a water-free reagent, as a gold-leaching lixiviant, resulting in a remarkable 96.5% gold extraction in just 2 hours. The researchers also modified the Merrill-Crowe cyanidation process by eliminating filtration and vacuum, instead utilizing bags filled with zinc (or aluminum) in the pulp. With reduced agitation to prevent aeration, over 99% of the gold precipitated on the zinc shavings within 2 hours. Furthermore, testing a hydrochloric solution (50%) with an oxidant demonstrated 83.9% and 100% gold extraction in 8 hours at ambient temperature and 50°C, respectively. It is crucial to note that successful implementation of these alternative strategies necessitates knowledge, investment, and customization to suit specific site conditions.

Published: August 2023

The metaverse, as a more advanced form of virtual reality, has great potential for education because of its unique affordances for enhancing immersion, interaction, and presence. However, because its development is still in its infancy, there are few empirical studies on the application of metaverse in education, with insufficient empirical evidence from the literature regarding its effectiveness and valued design features, as well as its advantages and disadvantages as a technology-enhanced learning environment. Utilizing the case study method, this study designed and implemented a 40-minute psychology course with 31 undergraduate students in the metaverse using the Virbela platform and collected both quantitative and qualitative data to empirically explore the benefits and challenges of the educational metaverse. The quantitative results showed that the students reported good learning experiences in the metaverse, but their learning outcomes were unsatisfactory, just over the passing level. The qualitative results revealed useful design features and common technical challenges of the educational metaverse. Based on the results, several implications for designing and developing effective courses in the educational metaverse were proposed.

Published: August 2023

In recent decades, attention has increased on the relationship between visual skills and sport. However, there are few studies on this topic in Paralympic sports and, about the perception of the influence of the visual system on the sports performance of athletes. The aim of this study was to determine the perception of wheelchair rugby players about the influence of the visual system in sport. Fifteen athletes of the Bogota and Cundinamarca Paralympic rugby team were included, who underwent a semi-structured interview. Among the results analyzed, it was found that for the participants the visual system provides different benefits in their sports performance, since it offers general and specific information about the game, such as the location of the ball, the players and the rivals on the court. From his perspective, it allows the discrimination of distances and helps in the correct execution of motor actions. In conclusion, the players highlight the contribution of the visual system in the proper execution of rugby, thanks to the interpretation of the information they receive from the environment; they highlight the importance of physical abilities such as stamina, strength, and speed, as well as mental abilities, such as logic and concentration.
INDONESIAN INHERITANCE SYSTEM BASED ON ISLAMIC LAW, CIVIL CODE, MATRILINEAL CUSTOMS, AND GENDER EQUALITY PERSPECTIVES
Authors: Gusti Malayudha Achmad , Sari Widya , Asiandu Angga Puja
Published: August 2023

In this article, the author discussed the inheritance system in Indonesia. The inheritance distribution system in Indonesia is based on Islamic law, civil code, and customary law. On the other hand, gender equality activists have their perspectives regarding the justice of the distribution system based on the proportion received by men and women. Based on the discussion, it was known that there are similarities and differences among Indonesian inheritance distribution systems. Each of the systems regulates that the testator must die and the main heirs are blood-related to the decedent. In Islam law, men receive more than a woman with a ratio of  2:1 due to men’s responsibility to their family. Meanwhile, the proportion between men and women regulated by the Indonesian civil code is equal. In Minangkabau matrilineal customary law, as a system based on the mother's lineage, the proportion of inheritance is distinguished between high inheritance and low inheritance. The high inheritance will be given to the woman and the low inheritance will be shared equally between men and women. However, some gender equality activists might see those proportions as a form of injustice. But, each of the systems has its perspective regarding justice.

Published: August 2023

Tablighi Jamaat's (TJ) proselytizing activity has had a significant impact on improving the religious practices of the community not only in India, where TJ was born and evolved, but also in other nations where they preach, including Indonesia. TJ's da'wah has reached rural places with strong customs. The purpose of this study is to investigate the growth and influence of TJ's da'wah movement in the Wetu Telu Bayan indigenous community in North Lombok. This study employs qualitative data collection approaches such as participant observation, in-depth interviews, and focus group discussions. According to the findings of this study, the beginning of TJ's da'wah expansion began with the movement of young people from the hamlet who were still in high school to Jamaah Tabligh's da'wah. He was successful in enticing the community to join by presenting various programs such as Safari Friday (Safari Jumat), a three-day church for spiritual growth. This program was strengthened by the Lombok Uatara Regent's program, namely emotional treatment (Termos) through khuruj, particularly Haji Bakrie, who is also a Tablighi Jamaat figure. This approach is highly effective and has a significant impact on the religious reformation in the Bayan customary region. Another study indicates that TJ members have successfully negotiated their teachings with traditional practices. The society began to renounce traditional practices that were seen incompatible with Islamic teachings.

Abstract
The demand for common carp (Cyprinus carpio) either its seed or consumption measures has increased every year. Fish growth can be increased by adding nutrients in the form of animal oil sources. An alternative ingredient that can be used to support fish growth with good nutritional content and relatively inexpensive is maggot oil or black soldier fly (H. illucens) oil. The purpose of this study was to determine the effect of maggot oil (H. illucens) in artificial feed on the growth performance of common carp and to determine the best dose of maggot oil. This study used a complete randomized design (CRD) with four treatments and three replicates: A, B, C, and D with the addition of maggot oil doses of 0%, 10%, 15%, and 20%, respectively. The test fish used was a common carp fry measuring 3.59±0.06 cm, 0.79±0.05 g. Observation time was 30 days with a stocking density of 15 fish/aquarium. The results showed that the addition of maggot oil (H. illucens) had a significant effect (P<0.05) on TFC, FCR, FUE, SGR, and survival. Based on the results of the study, the best dose was obtained in the addition of 15% maggot oil with value of TFC 10.57±0.26 g, FCR 1.52±0.03, FUE 65.43±1.54%, SGR 1.57±0.04%/day, and SR 95.56±3.85%. For further research, it is possible to use magot oil to increase carp production.

Published: August 2023

As one of the commercial and industrial cities in East Java, Sidoarjo has great potential in developing the SMEs sector. Uncertain capital constraints are difficult for SMEs. The ability to manage the finances of SMEs entrepreneurs is very important for business performance and business continuity. Without an understanding of SMEs about basic economic concepts, SMEs are unable to make financial management decisions. Most SMEs entrepreneurs, including SMEs entrepreneurs in Sidoarjo, experience this problem in general. Of course the problems faced will have serious consequences in the future, such as capital problems and tax consequences which will certainly affect the sustainability of the SMEs business. This activity is carried out in the form of training and mentoring. This program introduces resource persons who are professionals in their respective fields, through lecture techniques, discussions and mentoring practices, to the application of knowledge sharing methods to create an operational management system for company accounting and financial management. These trainees are members of the Batik Jetis Sidoarjo association who need special treatment in order to quickly rise from adversity and increase their profits by studying operational management of corporate accounting, corporate financial management and corporate governance. The AKUsaha application is an Android-based application developed according to the needs of SMEs. After attending the training, the student team assists the SMEs financial management process using the AKUsaha application face-to-face with SME players every month on Saturdays and Sundays. As a result, SME actors can understand the flow of cash coming in and out of their business, so that they can provide consideration for making business economic decisions. In addition, it is also useful for SMEs for reporting annual tax returns to applying for business capital loans.

Authors: Yuliawati Dwi , Ardhiani Innas Tiara
Published: August 2023

Newborns are prone to health problems due to a weak body defense system. Some problems that commonly arise in neonates include diseases in the mild category (which are common), for example: jaundice (physiological jaundice), vomiting, seborrheic dermatitis, oral trush, diarrhea, fever, diapper rush (diaper rash), miliariasis, constipation, and others. One of the preventive efforts to prevent complications in newborns is by providing health education aimed at increasing public knowledge about problems that often arise in newborns so that they can identify and take appropriate anticipatory and handling steps from existing problems.  Community service activities are carried out through talk show activities in the form of questions and answers between radio broadcasters and speakers regarding the theme of activities that have been previously determined and broadcast live streaming on the Youtube channel of RRI Malang in the Kiprah Indonesia program. The activity was carried out on September 5, 2022 with a duration of time during live Youtube, which is about 60 minutes. Community participation from the talk show is indicated by the total viewers on the You tube page of RRI Malang, which is 69 times watched and 10 “like”. Providing education in this community service activity is expected to affect the behavior of mothers and families in the detection and treatment of problems that often arise in newborns.

Today's journalists are required to have good competence and broad insight.  Not only be able to write factual information, but also have a good public speaking skills.  However, there are still many journalists who do not master public speaking so they often face some obstacles.  They are proficient at finding information in the field, but are nervous or insecure when dealing with other people or sources, so the interviews become unstructured and directed.  A journalist is also often asked to be a speaker in a seminar, training, or workshop, but since they are not used to speak in public, the presentation of the material becomes less interesting.  In fact, journalism is a profession that is expected to be at the forefront of society who must be able to speak loudly, truthfully, honestly, and courageously.  Having good public speaking skills can increase the confidence of journalists in conveying information and ideas, as well as providing education and motivation.  Because public speaking is an important competency, the Communication Department held a community service activity entitled "Public Speaking Training in Increasing Journalist Competence in Surabaya" on 13th and 20th October 2022, at Urban Office Surabaya.  The training was attended by journalists who are members of the Friends of Education Journalists (JSP) community.

The progress of tourism is heavily influenced by the professionalism and existence of its institutions (tourism institutions). In this community service, the Airlangga University Public Administration team partnered with the Diponegoro University Public Administration team to assist MSME partners in Wonolopo Semarang. The problem with partners is the need to strengthen tourism institutions and expand the marketing of MSME products including herbal medicine villages, flora villages selling ornamental plants, and so on. Wonolopo has 10 tourism awareness groups from 8 thematic villages. The solution to the partner problem is the transfer of knowledge of tourism institutional development. There are three choices of institutional forms, namely tourism awareness groups, cooperatives and BUMDesa. The solution to the second problem is information and communication technology-based marketing with Linktree which is shared on social media and using digital marketing platforms. The results achieved after the community service was carried out were that 98.3% of MSME actors and tourism managers in Wonolopo Semarang had increased their abilities in developing tourism institutions and digital marketing innovation, as much as 1.6% needed to be improved. For this reason, more intensive assistance is needed for partners in Wonolopo, Semarang.

In contrast to trivial bacterial pneumonia, the diagnosis of septic pulmonary embolism poses a fundamental task for the doctor to search for primary sources of emboli, including right side infective endocarditis, and to change the tactics of managing the patient accordingly. The similarity of the main clinical common and respiratory symptoms of septic pulmonary embolism with symptoms of other inflammatory processes in the lung makes their differential diagnosis difficult without the involvement of additional radiologic investigation methods. The review describes the special features of etiology and pathogenesis, as well as the clinic, complications and principles of diagnosis of septic embolic pneumonia.
On the Prospects for Democracy in the Muslim World
Authors: Malashenko A. , Nisnevich Y.
Published: August 2023

The democratic trend in the Muslim world is very difficult and contradictory. Its particularities need to be correctly studied what gives an opportunity to present suggestions about perspectives of democracy in Muslim states and societies. The Muslim world itself is composed of 47 states in which the majority consists of muslims added to them some other where the Muslim minority often possess a significant influence. Only several Muslim states could be classified as secular – among them Turkey, all states in Central Asia and some others. In the majority of those countries Islam isn’t accepted as source of law, clergymen don’t participate in taking key political decisions, but local administrations including of a high level evidently emphasize that their decisions are corresponding with the Islamic tradition. As far as Muslim monarchies, especially in the Persian Gulf, they carry out their politics according with religious norms but at the same time avoiding radicalization. They are opened to modernity. There are only two states – Iran and Afghanistan – whose fundamental pillars of the rule are based on Islamic law. In this article we describe how different regimes attempt to use some democratic norms (for example elections and multipartism) in order to consolidate themselves and to reach popularity. At the same time with a short number of exceptions they continue to stay authoritarian. Islam constantly influences on the social as well as on the political situation in the Muslim world. We shouldn’t exaggerate its impact but in the same time Islam’s presence in the political life shouldn’t be ignored. The Islamic factor and the Islamic tradition remain constant but they are not an absolute obstacle on the road to democratic process.
The Predicate of the Current Mathematical Knowledge Substantially Increases the Constructive and Informal Mathematics and Why It Cannot Be Adapted to Any Empirical Science
Authors: Tyszka Apoloniusz
Published: August 2023

This is a shortened and revised version of the article: A. Tyszka, Statements and open problems on decidable sets X⊆N, Pi Mu Epsilon J. 15 (2023), no. 8, 493-504. The main results were presented at the 25th Conference Applications of Logic in Philosophy and the Foundations of Mathematics, see http://applications-of-logic.uni.wroc.pl/XXV-Konferencja-Zastosowania-Logiki-w-Filozofii-i-Podstawach-Matematyki. We assume that the current mathematical knowledge is a finite set of statements which is time-dependent. In every branch of mathematics, the set of all knowable truths is the set of all theorems. This set exists independently of our current scientific knowledge. Nicolas D. Goodman observed in Synthese that epistemic notions increase the understanding of mathematics without changing its content as a formal science. This content remains also unchanged when the current mathematical knowledge leads to new conjectures. We explain the distinction between algorithms whose existence is provable in ZFC and constructively defined algorithms which are currently known. By using this distinction, we obtain non-trivial statements on decidable sets X⊆N that belong to constructive and informal mathematics and refer to the current mathematical knowledge on X. This and the next sentence justify the article title. For any empirical science, we can identify the current knowledge with that science because truths from the empirical sciences are not necessary truths but working models of truth from a particular context.

Published: August 2023

We carry out a systematic study on the motion of test particles in the region inner to the naked singularity of a quasi–hyperbolically symmetric γ-metric. The geodesic equations are written and analyzed in detail. The obtained results are contrasted with the corresponding results obtained for the axially symmetric γ-metric, and the hyperbolically symmetric black hole. As in this latter case, it is found that test particles experience a repulsive force within the horizon (naked singularity), which prevents them to reach the center. However in the present case this behavior is affected by the parameter γ which measures the departure from the hyperbolical symmetry. These results are obtained for radially moving particles as well as for particles moving in the θ−r subspace. Possible relevance of these results in the explanation of extragalactic jets, is brought out. .

Kidney transplant recipients (KTR) show higher morbidity and mortality from COVID-19 than the general population and have an impaired response to vaccination. We analyzed COVID-19 incidence and clinical outcomes in a single-center cohort of approximately 2500 KTR. Between February 1, 2020 and July 1, 2022, 578 KTR were infected with SARS-CoV-2, with 25 (4%) recurrent infections. 208 KTR (36%) were hospitalized, and 39 (7%) died. Among vaccinated patients, infection with the Omicron variant had a mortality of 2%. Unvaccinated patients infected with the Omicron variant showed mortality (9% vs. 11%) and morbidity (hospitalization 52% vs. 54%, ICU-admission 12% vs. 18%) comparable to the pre-Omicron era. Multivariable analysis revealed, being unvaccinated (OR = 2.15, 95% CI [1.38, 3.35]), infection in the pre-Omicron era (OR = 3.06, 95% CI [1.92, 4.87]), and higher patient age (OR = 1.04, 95% CI [1.03, 1.06]) are independent risk factors for COVID-19 hospitalization, whereas steroid-free immunosuppressive regimen was found to reduce the risk of COVID-19 hospitalization (OR = 0.51, 95% CI [0.33, 0.79]). This suggests that both, virological changes in the Omicron variant and vaccination, reduce the risk for morbidity and mortality from COVID-19 in KTR. Our data extend the knowledge from the general population to KTR and provide important insights into outcome during the Omicron era.

Alzheimer’s disease(AD) progression correlates with the propagation of hyperphosphorylated Tau (pTau) from the entorhinal cortex to the hippocampus and neocortex. Neutral sphingomyelinase2(nSMase2) is critical in the biosynthesis of extracellular vesicles (EVs), which play a role in pTau propagation. We recently conjugated DPTIP, a potent nSMase2 inhibitor, to hydroxyl-PAMAM-dendrimer nanoparticles which can improve brain delivery. We showed that dendrimer-conjugated-DPTIP (D-DPTIP) robustly inhibited pTau spread in an AAV-pTau propagation model. To further evaluate its efficacy, we tested D-DPTIP in the PS19 transgenic mouse model. Unexpectantly, D-DPTIP showed no beneficial effect. To understand this discrepancy, we assessed D-DPTIP’s brain localization. Using immunofluorescence and fluorescence-activated cell-sorting, D-DPTIP was found to be primarily internalized by microglia where it selectively inhibited microglial nSMase2 activity with no effect on other cell types. Furthermore, D-DPTIP inhibited microglia-derived EV release into plasma without affecting other brain-derived EVs. We hypothesize that microglial targeting allowed D-DPTIP to inhibit tau propagation in the AAV-hTau model, where microglial EVs play a central role in propagation. However, in PS19 mice, where tau propagation is independent of microglial EVs, it had a limited effect. Our findings confirm microglial targeting with hydroxyl-PAMAM dendrimers and highlight the importance of understanding cell-specific mechanisms when designing targeted AD therapies.

Future generations gain by learning from elders' life experiences, as do older adults themselves who share their memories. Despite Oman's sizable geriatric population, research on older individuals' life experiences is scarce. Therefore, this study aims to explore the life experiences of older Omani individuals across their many life stages, from childhood to the present. Methods: This was a qualitative study design. A total of 13 Omani older adults (9 females and 4 males) with an average age of 68 years were recruited for this study. Socio-demographic and life review information was gathered according to a set of semi-structured guiding questions. The responses were then captured on audio recordings, which underwent transcription and translation. Thematic analysis techniques were applied to the extracted data. Results: Three main themes were evident in the study’s findings: Childhood memories, Friendships, and Relationships, as well as the elders’ past. Additionally, older adults passed on a number of gems of wisdom to be shared with the younger generations. Conclusion: This study aided in revealing the resiliency, social connections, and life reflections of Omani older adults. Based on these findings, future studies might explore particular aspects of older experiences and pinpoint solutions to improve their quality of life and well-being.

Gastric cancer (GC) is a highly heterogeneous, complex disease and the fifth most common cancer worldwide (about one million cases and 784 000 deaths worldwide in 2018). CG is lately diagnosed and guarantees a poor prognosis for GC (the 5-year survival rate is less than 20%, but in early detection can reach 90%). This study evaluated the transcriptional profile in tumor gastric samples to find genes highly expressed during tumor establishment and use the related proteins as targets to find new anticancer molecules. Data was collected at Gene Expression Omnibus (GEO) bank to obtain 3 dataset matrices that analyze gastric tumor tissue versus normal gastric tissue, performed microarray using GPL570 platform, and from different sources. The genes found in silico analysis were confirmed in several lines of GC cells by RT-qPCR. The protein data bank was used to find the correspondent proteins. Then a structural-based virtual screening was done to find molecules, and docking analysis was done using the DockThor server. Our results of transcriptomic analysis, together with RT-qPCR, confirm the high expression of the genes AJUBA, FBXL13, CCDC69, CD80 and NOLC1 in GC lines. Based on that, the correspondent proteins were used in SBVS analysis. Five molecules, one each target, MCULE-2386589557-0-6, MCULE-7343047040-0-1, MCULE-5230409338-0-3, MCULE-9178344200-0-1 and MCULE -5881513100-0-29. All molecules have favorable pharmacokinetic, pharmacodynamic and toxicological properties. Molecular docking analysis revealed that the molecules interact with proteins in critical sites for their activity. Using a virtual screening approach, a molecular docking study was performed for proteins encoded by genes that play important roles in cellular functions for carcinogenesis. Combining a systematic collection of public microarray data with a comparative meta-profiling, RT-qPCR, SBVS, and molecular docking analysis provided a suitable approach to find genes involved in GC and work the correspondent protein to strive for new molecules with anticancer properties.
Surveying ‘Dating Violence’ and Stalking Victimisation among Students at a UK University: Findings and Methodological Reflections on Using a US Survey Instrument
Authors: Bull Anna Louise , Bradley Alexander
Published: August 2023

Domestic abuse and stalking in higher education (HE) have been overlooked in research in comparison to sexual harassment and sexual violence. This article reports on survey data from 725 students at a UK university using measures of ‘dating violence’ – physical and psychological violence from an intimate partner – and stalking from a US survey instrument (the Administrator Researcher Campus Climate Collaborative (ARC3) survey). According to this measure, 26% of respondents had been subjected to ‘dating violence’ and 16% to stalking behaviours. However, these findings need to be contextualised within a critical discussion of the use of the ARC3 survey tool in the UK context. The ARC3 questions on ‘dating violence’ focus on physical and ‘psychological violence’; the questions therefore omit further types of domestic abuse under UK definitions. In relation to stalking, US definitions – as captured in the ARC3 survey instrument – define specific behaviours. By contrast, in the UK stalking involves behaviours that engender fear or distress in a pattern of behaviour over time. These differences mean that the ARC3 modules on stalking and ‘dating violence’ would need to be significantly adapted to be suitable for use in the UK context.
A Method of Measuring the Absolute Position and Attitude Parameters of a Moving Rigid Body Using a Monocular Camera

Published: August 2023

A method of measuring the absolute pose parameters of a moving rigid body using a monocular camera is proposed, aiming at addressing calibration difficulties and inconsistencies of repeated measurements of the rigid-body pose for a camera having a varying focal length. The proposed method does not require calibration beforehand. Using more than six non-coplanar control points symmetrically arranged in the rigid-body and world coordinate systems, the matrices of rotation and translation between the camera and two coordinate systems are obtained and the absolute pose of the rigid body measured. In this paper, formulas of the absolute pose measurement of a moving rigid body are deduced systematically and the complete implementation is presented. Position and attitude measurement experiments carried out on a three-axis precision turntable show that the average absolute error in the attitude angle of a moving rigid body measured by an uncalibrated camera at different positions changes by no more than 0.2 degrees. Analysis of the three-dimensional coordinate errors of the centroid of a moving rigid body shows little deviation in measurements made at three camera positions, with the maximum deviation of the average absolute error being 0.53 cm and the maximum deviation of the standard deviation being 0.66 cm. The proposed method can measure the absolute pose of a rigid body and is insensitive to the position of the camera in the measurement process. This work thus provides guidance for the repeated measurement of the absolute pose of a moving rigid body using a monocular camera.
Stakeholders’ Perceptions of How Nurse-Doctor Communication Impacts Patient Care: A Concept Mapping Study
Authors: Pantha Sandesh , Jones Martin , Gray Richard
Published: August 2023

There is some evidence that aspects of nurse-doctor communication are associated with the quality of care and treatment patients receive whilst they are in hospital. To date, no studies have examined stakeholder perceptions of how patient care is influenced by clinical communication between nurses and doctors. We conducted a concept mapping study to generate a deep understanding of how clinical communication impacts patient care. Concept mapping has six phases: preparation, idea generation, structuring, representation, interpretation, and utilization. Twenty patients, 21 nurses, and 21 doctors participated in the study. Brainstorming generated 69 discreet statements about how nurse-doctor communication impacts patient care. The structuring (rating and clustering) phase was completed by 48 participants. The data interpretation workshop selected a five-cluster solution: effective communication, trust, patient safety, impediments to patient care, and interpersonal skills. On the final concept map, the five clusters were arranged in a circle around the center of the map. Clusters were relatively equal in size suggesting, each concept makes a broadly equal contribution to how nurse-doctor communication influences patient care. Our study suggests that there are multiple aspects of clinical communication that impact patient care. Candidate interventions to enhance nurse-doctor communication may need to consider the complex nature of interprofessional working.
Registration: This study was prospectively registered with the Open Science Framework (OSF) (https://osf.io/9np8v/) prior to recruiting the first participant.
A Survey Of Henipavirus Tropism—Our Current Understanding From A Species/Organ And Cellular Level
Authors: Diederich Sandra , Babiuk Shawn , Boshra Hani
Published: August 2023

Henipaviruses are single-stranded RNA viruses that have been shown to be virulent in several species including humans, pigs, horses, and rodents. Isolated nearly 30 years ago, these viruses have been shown to be of particular concern to public health, as at least two members (Nipah and Hendra viruses) are highly virulent, as well as zoonotic, and are thus classified as BSL4 pathogens. Although only 5 members of this genus have been isolated and characterized, metagenomics analysis using animal fluids and tissues has demonstrated the existence of other novel henipaviruses, suggesting a far greater degree of phylogenetic diversity than currently known. Using a variety of molecular biology techniques, it has been shown that these viruses exhibit varying degrees of tropism, on a species, organ/tissue, and cellular level. This review will attempt to provide a general overview of our current understanding of henipaviruses, with particular emphasis on viral tropism.
The Impact of Agricultural Credit on the Growth of the Agricultural Sector in Angola
Authors: Caetano Joao Mario A. , Castro Abreu Monteiro de
Published: August 2023

Some doubts have been expressed about the accuracy of econometric models that measure the real impact that banking financial institutions have on boosting the agricultural sector in particular and, more broadly, the real sector. Besides financial credit provided by the banking sector, many macro- and microeconomic variables, as well as business environment variables, have been found to impact growth. Poor banking sector performance has consequences on economic activity, leading to economic contraction, and vice versa. The ultimate goal of this paper was to examine the degree of elasticity between two variables, namely, agricultural credit and agricultural growth, in Angola in the period between 2003 and 2022. The outcome of this analysis indicated that agricultural credits have significant impact on agricultural growth.
