Psychosocial Impacts of COVID-19 Pandemic on West Africans Based in Victoria Australia who Survived the 2014-16 Ebola Epidemic: The Methodological Approach

Background: COVID-19 pandemic caused some obvious psychosocial distress in virtually all aspects and works of life. This has led to massive volumes of research. Yet, concerns for preparedness against future disease outbreak remains. One of such concerns is around mental health care. Therefore, a research agenda is to investigate the psychosocial impact of COVID-19 as perceived by Australian-based West Africans who survived the 2014-2016 Ebola epidemic before coming to Australia. Objective: The objective of this article is to describe the options of research methods that have been considered. Method: The description was designed to take a narrative approach. As such, vivid descriptions of potentially applicable research methods are presented. Outcome: Paradigms as well as concepts of qualitative and quantitative research rationales are discussed. Sequential approach in mixed-method research is also described. Limitations of the different methodological options are highlighted to inform their pros and cons. Conclusion: The significance of this article is elucidation of methodologies that underpin the selected methods in the research project.

A critical realist approach to agent-based modeling: Unlocking prediction in non-positivist paradigms

Information systems (IS) scholarship and practice aim to predict phenomena and outcomes of IS use. These phenomena of IS use are typically set in multi-leveled, dynamic, and complex contexts that lend explanation to the non-positivist tradition in IS research. However, limited methodological options exist to make predictions. In this research, we propose stratified agent-based modeling, a step-by-step approach that enables prediction in non-positivist paradigms. Drawing upon the critical realist philosophy of science, which suggests ontological stratification and assumes open systems, we adopt a retroduction-based explanation formation and agent-based modeling to simulate different potential states of a complex system. The critical step in combining critical realism with agent-based modeling involves identifying and codifying the underlying generative mechanisms (i.e., causal powers) into various components of the agent-based model. We propose four steps toward prediction under the critical realist paradigm: (1) capturing the phenomenon, (2) identifying the generative mechanism, (3) building the agent-based model, and (4) simulating states of the system. We present an exemplar of our proposed approach that investigates the effectiveness of strategies to combat malicious content propagation in social networks.

Delphi Technique on Nursing Competence Studies: A Scoping Review.

This scoping review was conducted under the Joanna Briggs Institute (JBI) framework. It included primary studies published until 30 April 2023, obtained through a systematic search across PubMed, Web of Science, CINAHL, and MEDLINE databases. The review focused on primary studies that used the Delphi technique in nursing competence research, especially those related to defining core competency frameworks and developing instruments to assess professional competence. The goal was to analyze the different methodological approaches used by authors, synthesize them, and propose recommendations to enhance methodological rigor, reliability, and validity in the application of the Delphi technique. For this purpose, the following review question was established: "What is the available evidence on the use of the Delphi technique in the study of professional competence in nursing?". The extracted textual elements underwent a content analysis, resulting in dimensions established through an inductive approach. Twenty studies were included, yielding insights into diverse methodological options for conducting Delphi studies, organised around a set of dimensions: (1) preparatory procedures; (2) procedures for accessing and selecting experts; (3) acquisition of expert input; (4) data analysis and consensus; and (5) ethical and legal procedures and guarantees. The study's limitations include the inability to include certain studies due to a lack of response to requests for clarification from corresponding authors. Additionally, the primary studies' methodological quality was not assessed, which is another relevant aspect. The study's results offer valuable insights for researchers intending to utilise the Delphi technique within the context of the research referenced in the included studies. This information encompasses important methodological choices, highlighting their potential benefits and associated risks. The review was prospectively registered on the Open Science Framework (Registration No: osf.io/kp2vw).

DESIGN SCENARIOS AND ECOTOPIAS. NOTES FOR THE DEVELOPMENT OF A SOCIO-ENVIRONMENTAL DESIGN LABORATORY

This paper presents the conceptual underpinnings organized by a group of designers and design researchers for the creation of the Ecotopias Socioenvironmental Design Laboratory at PUC-Rio University. It begins by discussing the anthropogenic crisis, which the planet is currently facing, and the consequent design crisis. It also presents the field of design for sustainability, its transversality and eco-logic possibilities. It situates the process of constructing scenarios in this field as a methodological option for opening the imaginative and anticipatory potential of art and design to confront the planetary environmental crises and regenerate ecologies of the mind, social relations, and the environment. It describes the methodological steps of the scenario-building process derived from the project Sustainable Everyday, and, finally, it distinguishes the concepts of utopia and ecotopia.

Translation, Cross-Cultural Adaptation, and Validation of Measurement Instruments: A Practical Guideline for Novice Researchers.

Cross-cultural validation of self-reported measurement instruments for research is a long and complex process, which involves specific risks of bias that could affect the research process and results. Furthermore, it requires researchers to have a wide range of technical knowledge about the translation, adaptation and pre-test aspects, their purposes and options, about the different psychometric properties, and the required evidence for their assessment and knowledge about the quantitative data processing and analysis using statistical software. This article aimed: 1) identify all guidelines and recommendations for translation, cross-cultural adaptation, and validation within the healthcare sciences; 2) describe the methodological approaches established in these guidelines for conducting translation, adaptation, and cross-cultural validation; and 3) provide a practical guideline featuring various methodological options for novice researchers involved in translating, adapting, and validating measurement instruments. Forty-two guidelines on translation, adaptation, or cross-cultural validation of measurement instruments were obtained from "CINAHL with Full Text" (via EBSCO) and "MEDLINE with Full Text". A content analysis was conducted to identify the similarities and differences in the methodological approaches recommended. Bases on these similarities and differences, we proposed an eight-step guideline that includes: a) forward translation; 2) synthesis of translations; 3) back translation; 4) harmonization; 5) pre-testing; 6) field testing; 7) psychometric validation, and 8) analysis of psychometric properties. It is a practical guideline because it provides extensive and comprehensive information on the methodological approaches available to researchers. This is the first methodological literature review carried out in the healthcare sciences regarding the methodological approaches recommended by existing guidelines.

Variability and bias in microbiome metagenomic sequencing: an interlaboratory study comparing experimental protocols.

Several studies have documented the significant impact of methodological choices in microbiome analyses. The myriad of methodological options available complicate the replication of results and generally limit the comparability of findings between independent studies that use differing techniques and measurement pipelines. Here we describe the Mosaic Standards Challenge (MSC), an international interlaboratory study designed to assess the impact of methodological variables on the results. The MSC did not prescribe methods but rather asked participating labs to analyze 7 shared reference samples (5 × human stool samples and 2 × mock communities) using their standard laboratory methods. To capture the array of methodological variables, each participating lab completed a metadata reporting sheet that included 100 different questions regarding the details of their protocol. The goal of this study was to survey the methodological landscape for microbiome metagenomic sequencing (MGS) analyses and the impact of methodological decisions on metagenomic sequencing results. A total of 44 labs participated in the MSC by submitting results (16S or WGS) along with accompanying metadata; thirty 16S rRNA gene amplicon datasets and 14 WGS datasets were collected. The inclusion of two types of reference materials (human stool and mock communities) enabled analysis of both MGS measurement variability between different protocols using the biologically-relevant stool samples, and MGS bias with respect to ground truth values using the DNA mixtures. Owing to the compositional nature of MGS measurements, analyses were conducted on the ratio of Firmicutes: Bacteroidetes allowing us to directly apply common statistical methods. The resulting analysis demonstrated that protocol choices have significant effects, including both bias of the MGS measurement associated with a particular methodological choices, as well as effects on measurement robustness as observed through the spread of results between labs making similar methodological choices. In the analysis of the DNA mock communities, MGS measurement bias was observed even when there was general consensus among the participating laboratories. This study was the result of a collaborative effort that included academic, commercial, and government labs. In addition to highlighting the impact of different methodological decisions on MGS result comparability, this work also provides insights for consideration in future microbiome measurement study design.

A Multimethodological Approach to Assist the Design of Systemic Governance in Agroextractivist Settlement Projects in the Brazilian Amazon Landscape.

Coping with complex landscape situations in the Anthropocene increasingly demands innovative governance practices that can be facilitated by investment in new epistemological and methodological approaches and capacities. This paper explores the use of a multimethodological research approach organized as a systemic co-inquiry to assist in the design of systemic governance for Agroextractivist Settlement Projects (PAEs) in the municipality of Abaetetuba, Pará, in the Brazilian Amazon. In the PAEs, the systemic co-inquiry was conducted alongside interested and influential stakeholders through the combined use of the Soft Systems Methodology and Strategic Options Development and Analysis problem structuring methods. The use of these methods and their tools allowed stakeholders to articulate major issues around the situation of concern, engaging in reflective practices about the opportunities of governing the PAEs systemically. By valuing stakeholder perspectives and participation in all phases of the research, the proposed multimethodology approach helped them express their views on the problem situation and allowed for their active engagement in the design of systemic governance of the PAEs. As a result of adopting a multimethodological approach, distinctive albeit coupled realms of governing are explored, a key issue when designing systemic governance practices of social-ecological systems such as the PAEs.

Effect of Surface Roughness on Aerodynamic Loads of Bluff Body in Vicinity of Smoothed Moving Wall

This paper contributes to a new Lagrangian vortex method for the statistical control of turbulence in two-dimensional flow configurations around a rough circular cylinder in ground effect when considering higher subcritical Reynolds numbers, namely 3 × 104 ≤ Re ≤ 2 × 105. A smoothed moving wall (active control technique) is used to include the blockage effect in association with the variation in cylinder surface roughness (passive control technique), characterizing a hybrid approach. In contrast with the previous approaches of our research group, the rough cylinder surface is here geometrically constructed, and a new momentum source term is introduced and calculated for the investigated problem. The methodology is structured by coupling the random Discrete Vortex Method, the Lagrangian Dynamic Roughness Model, and the Large Eddy Simulation with turbulence closure using the truncated Second-Order Velocity Structure Function model. This methodological option has the advantage of dispensing with the use of both a refined near-wall mesh and wall functions. The disadvantage of costly processing is readily solved with Open Multi-Processing. The results reveal that intermediate and high roughness values are most efficient for Reynolds numbers on the orders of 105 and 104, respectively. In employing a moving wall, the transition from the large-gap to the intermediate-gap regime is satisfactorily characterized. For the conditions studied with the hybrid technique, it was concluded that the effect of roughness is preponderant and acts to anticipate the characteristics of a lower gap-to-diameter ratio regime, especially with regard to intermittency.

Talking about Oneself to Talk about Christ: The Autobiographical Text of Philippians 3:1–4.1 in Light of Ancient Rhetorical Heritage

In this contribution, we will proceed in three steps. First of all, we will investigate the rhetorical approach for studying the Pauline letters, considering different methodological options. In this context, we will propose the approach of the literary rhetoric as the most valid. Secondly, we will analyse the autobiographical text of Philippians 3:1–4:1, starting from its delimitation, textual criticism, and its arrangement, according to oral and discursive models. Then, we will proceed with genre and literary origins; here, we will discover the periautologia as the point of reference of the Pauline autobiography. This eulogy of self is a genre, well known in the rhetorical tradition, to which Plutarch dedicated the treatise On praising oneself. This discovery determines the following exegetical analysis of the text. Thirdly, we will conclude with a reflection about Paul’s way of speaking about himself in this passage. In light of ancient rhetorical heritage, he does not use his autobiography to praise himself but to praise Christ, who completely changed his life. Ultimately, Paul’s talk about himself is a way of talking about Christ for the benefit of the addressees who should creatively imitate the Apostle and his Christian life.

Survey of MCDM-Based Software Engineering Method

Multi-criteria decision making (MCDM) is an operation research subfield (OR). Decision-making is primarily a process involving various actors, including individuals, groups of individuals, institutions, and the state. As a discipline, multi-criteria decision-making is relatively new Many researchers have devoted their time to developing new MCDM models and techniques since the 1950s and 1960s, when the foundations of modern multi-criteria decision-making methods were laid. Research and development in the area have intensified recently and appear to be developing tremendously. Few attempts have been made to systematically convey the theoretical foundations and advancements of multi-criteria decision-making systems, despite the widespread and intense development. The framework for evaluating judgments and the methodological options are still up for debate. In this paper reviews of MCDM/MADM technologies will be included describing their scenarios. Making a decision that is more appropriate than others to solve a particular problem is the goal of decision-making (DM), so this study presents a review of the advantages and disadvantages of different decision-making techniques, specifically in the field of software engineering.

Ethical awareness and professional responsibility: educating translators to tackle diversifying industry dilemmas

ABSTRACT Ethical awareness is arguably becoming ever more relevant with the increasing digitalisation of professional practice. Ethical dilemmas are changing in nature, becoming more diverse and more difficult to tackle, also as technologically infused realities give rise to more blurry boundaries. Language professionals, in training for the roles of the future, require a strong sense of professional responsibility. This correlates with the ability to define their own ethical profiles and to apply them agilely to navigate evolving industry expectations. Ethical profiling is paramount if graduates of translation education are to confidently engage with the variety of emerging language-based roles, including those that involve significant automation. This article focusses on professional ethical requirements for the language industry as exhibited in the Romanian national context and describes educational tools that may support the development of ethical awareness for newly trained translators. The article reports on a pedagogical model applied with second year master’s students in translation, which can ensure increased explicit exposure to ethically-charged professional scenarios as part of curriculum design. The suggestive model aims to mould professional ethical behaviours of trainee translators and to equip them with methodological options to support the continuous enhancement of their professional profiles while realistically assessing market developments and identifying shifts in ethical expectations.

Investigating Interdisciplinarity and Transdisciplinarity: How Meta-Ethnography Contributes to the Study of Collaborative Research Practices

Interdisciplinarity and transdisciplinarity are collaborative research modes that help advance science dealing with grand societal challenges. However, many factors still act as obstacles to high-impact research, showing disconnections between practices and policies. We can reasonably question whether we are still incapable of applying the correct methods to grasp interdisciplinary and transdisciplinary heterogeneity. This article aims to deepen the discussion of the methodological options for critically studying interdisciplinarity and transdisciplinarity. By applying meta-ethnography to the inter- and transdisciplinary academic literature, the paper inquires about the suitability of the method to study bodies of knowledge on interdisciplinarity and transdisciplinarity. Meta-ethnography is a seven-phase literature review type of meta-synthesis aimed at creating new understandings and theories from a body of work. Applying an autoethnographic approach, I show how meta-ethnography allows for the reconceptualisation of a disparate and dispersed body of literature, advancing current discussions on inter- and transdisciplinarity and their roles in science and policy. The approach outlined in the article is innovative because it contributes to two related realms: (i) it helps advance the field of inter- and transdisciplinary research and policy because it refines the methods available to study these multidimensional practices, and (ii) it offers an example of the further adaptability of meta-ethnography to new topics, such as the investigation of collaborative settings. I analyse six challenges in light of the scientific literature and conclude by focusing on the value meta-ethnography has for studying interdisciplinary and transdisciplinary research and propose two methodological innovations.

What do we mean by constitutional supremacy?

This paper offers a comment on Paolo Sandro’s “The making of constitutional democracy”. It discusses Sandro’s choice of defining modern constitutionalism as legal otherness from two perspectives. First, Sandro’s methodological option for discussing constitutional theory is addressed by looking at legal traditions, clarifying the extent to which comparative constitutional law can help the development of studies in legal theory. Second, it addresses the accounts of constitutionalism that Sandro introduces in his work to set the scene for the discussion of the conditions for the existence and endurance of constitutional democracy.

Review of the effects of Task-based Language Teaching on EFL learners’ speaking performance: What remains to be researched?

Given the research trend on task-based language teaching (TBLT), several reviews have been conducted on its effects. However, no review has explored specific skills. This study aims to review previous studies with a focus on the improvement of EFL learners’ speaking performance. The main purpose is to reveal a gap for future study. Using the systematic review approach, we selected 25 qualified studies from different databases. Results showed that TBLT implementation promoted both general speaking and speaking components (i.e., complexity, accuracy, and fluency). Most of the studies either employed or adapted Willis’ model. The present study suggests that future research could explore the comparative effects of various task-based methodological options. Moreover, the text-driven approach to task design and implementation can be further researched to enhance EFL learners’ engagement and speaking performance.

Increasing Access to Contraception: Examining Barriers and Facilitators of Long-Acting Reversible Contraception.

Objective(s): To identify barriers and facilitators related to reimbursement processes, device acquisition costs, stocking, and supply of long-acting reversible contraception (LARC) from 27 jurisdictions (26 states/1 territory) participating in the Increasing Access to Contraception Learning Community from 2016 to 2018. Materials and Methods: A descriptive study using qualitative data collected through 27 semistructured key informant interviews was conducted during the final year of the learning community among all jurisdictional teams. Excerpts were extracted and coded by theme, then summarized as barriers or facilitators using implementation science methods. Results: Most jurisdictions (89%) identified barriers to reimbursement processes, device acquisition, stocking, and supply of LARC devices, and 85% of jurisdictions identified facilitators for these domains. Payment methodology challenges and lack of billing and coding processes were identified as the most common barriers to reimbursement processes. Device acquisition cost challenges and lack of delivery facility protocols for billing were the most common barriers to device acquisition, stocking, and supply of LARC. The most common facilitator of reimbursement processes was expanded payment methodology options, whereas supplemental funding for acquisition costs and protocol development were identified as the most common facilitators of device acquisition, stocking, and supply. Conclusion: Revised payment methodologies and broader health systems changes including additional funding sources and protocols for billing, stocking, and supply were used by learning community jurisdictions to address identified barriers. The learning community framework offers a forum for information exchange, peer-to-peer learning, and sharing of best practices to support jurisdictions in addressing identified barriers and facilitators affecting contraception access.

How remote sensing choices influence ecosystem services monitoring and evaluation results of ecological restoration interventions

Large-scale ecological restorations are recognized worldwide as an effective strategy to combat environmental degradation and promote sustainability. Remote sensing (RS) imagery, such as obtained from Landsat and Sentinel-2 satellites, can provide spatial, spectral, and temporal information on ecosystem service supply to support monitoring and evaluation of restoration interventions. However, because of the abundance of satellite data and methodological analysis options, choices in data selection and processing options need to be made. This study explored the effect of RS choices on the evaluation of changes in ecosystem services as a result of ecological restoration interventions. Using the ecosystem service of forage provision for wildlife as an example, we used a before-after-control-impact (BACI) analysis to compare how the following choices affected restoration evaluation outcomes: a) different number of control pixels; b) different spatial distribution of control pixels; c) intra-annual image selection; and d) different reference periods. In addition, e) we evaluated the effect of using two different satellite sensor types, using the ecosystem service ‘erosion prevention’ as an example. We explored the effect of these five choices for restoration sites in the Baviaanskloof, South Africa. Results showed that the choice of intra-annual image selection, and the reference period describing the ‘before state’ had a strong effect on the outcomes, often leading to opposite BACI evaluation results. BACI results were less sensitive to choices related to the number of control points in the evaluation. The impact of methodological choices on the BACI outcomes was greater for the less degraded areas of our study site. Satellite sensor choice resulted in similar temporal trajectories of estimated supply. We demonstrated that RS choices have a strong effect on the evaluation results of restoration interventions. Therefore, we recommend that documenting the key RS choices results is essential when communicating restoration evaluation results in order to properly understand, manage and adapt restoration initiatives.

The method of using the online course “Creative Thinking through Learning Elementary Maths” in the Mathematics teacher training system

The article offers the method of using the online “Creative Thinking through Learning Elementary Maths” and the results of checking the effectiveness of the implementation of this course in the mathematics teacher training system. The research substantiates the possibility of three methodological options for combining educational materials of the online course with the study of the educational discipline “Elementary Mathematics”. The methodological options are chosen depending on the number of credits assigned to the study of the elementary mathematics course at the university. Practical tasks of the course were focused on the organization of students’ activities (recognition, classification, solving and creation) with Rich tasks of three levels of complexity. The results of control tests in Elementary Mathematics give grounds for concluding about the effectiveness of the developed method.

Identifying Optimal Methods for Addressing Confounding Bias When Estimating the Effects of State-level Policies.

Policy evaluation studies that assess how state-level policies affect health-related outcomes are foundational to health and social policy research. The relative ability of newer analytic methods to address confounding, a key source of bias in observational studies, has not been closely examined. We conducted a simulation study to examine how differing magnitudes of confounding affected the performance of 4 methods used for policy evaluations: (1) the two-way fixed effects difference-in-differences model; (2) a 1-period lagged autoregressive model; (3) augmented synthetic control method; and (4) the doubly robust difference-in-differences approach with multiple time periods from Callaway-Sant'Anna. We simulated our data to have staggered policy adoption and multiple confounding scenarios (i.e., varying the magnitude and nature of confounding relationships). Bias increased for each method: (1) as confounding magnitude increases; (2) when confounding is generated with respect to prior outcome trends (rather than levels), and (3) when confounding associations are nonlinear (rather than linear). The autoregressive model and augmented synthetic control method had notably lower root mean squared error than the two-way fixed effects and Callaway-Sant'Anna approaches for all scenarios; the exception is nonlinear confounding by prior trends, where Callaway-Sant'Anna excels. Coverage rates were unreasonably high for the augmented synthetic control method (e.g., 100%), reflecting large model-based standard errors and wide confidence intervals in practice. In our simulation study, no single method consistently outperformed the others, but a researcher's toolkit should include all methodologic options. Our simulations and associated R package can help researchers choose the most appropriate approach for their data.

Τὸ εὐαγγέλιον τὸ εὐαγγελισθὲν ὑπ’ ἐμοῦ (Gal 1:11)

Abstract In this contribution the author will proceed in three steps. First, he will raise questions about the various rhetorical approaches one might follow in order to study the argumentative development of Galatians, considering the different methodological options. Second, he will offer a survey of existing rhetorical research on Galatians. Then he will seek to outline the argumentative structure and development of Galatians, in order to understand what is really at stake in this Pauline letter. At the end it will be proven that the literary rhetorical approach in studying Galatians is highly useful for a deep understanding of the text of the letter and its aim: Paul wants to re-evangelise the addressees.

Inter-comparison of marine microbiome sampling protocols

Research on marine microbial communities is growing, but studies are hard to compare because of variation in seawater sampling protocols. To help researchers in the inter-comparison of studies that use different seawater sampling methodologies, as well as to help them design future sampling campaigns, we developed the EuroMarine Open Science Exploration initiative (EMOSE). Within the EMOSE framework, we sampled thousands of liters of seawater from a single station in the NW Mediterranean Sea (Service d'Observation du Laboratoire Arago [SOLA], Banyuls-sur-Mer), during one single day. The resulting dataset includes multiple seawater processing approaches, encompassing different material-type kinds of filters (cartridge membrane and flat membrane), three different size fractionations (>0.22 µm, 0.22–3 µm, 3–20 µm and >20 µm), and a number of different seawater volumes ranging from 1 L up to 1000 L. We show that the volume of seawater that is filtered does not have a significant effect on prokaryotic and protist diversity, independently of the sequencing strategy. However, there was a clear difference in alpha and beta diversity between size fractions and between these and “whole water” (with no pre-fractionation). Overall, we recommend care when merging data from datasets that use filters of different pore size, but we consider that the type of filter and volume should not act as confounding variables for the tested sequencing strategies. To the best of our knowledge, this is the first time a publicly available dataset effectively allows for the clarification of the impact of marine microbiome methodological options across a wide range of protocols, including large-scale variations in sampled volume.
