Assessing the scientific integrity of the collected work of one author or author group.

No published methods for research integrity review include both statistical techniques applied to groups of randomized trials and individual assessment of papers. We propose a method based on practical experience of investigating data integrity across the collected papers of an author or author group. We report our approach to investigating the collected papers of an author or author group suspected of academic misconduct. In the investigation of the work of an author or author group, we recommend a systematic search for the work of the involved authors in PubMed, Google Scholar, and the Retraction Watch database, as well as a search of trial registries for unpublished clinical trials. Summary information from studies should be tabulated to assess consistency between study registration, execution, and publication. Each paper should be investigated for unfeasible features of the governance, methodology, execution, results, and reporting of the study. Pairwise comparison of baseline and outcome tables between papers may reveal data duplication or unfeasibly large differences between baseline characteristics in similar studies. Assessment of baseline characteristics from multiple randomized trials using Carlisle's method can determine whether the data are consistent with a properly executed randomization process, as can checking whether reported baseline characteristics follow expected patterns for random variables such as Benford's law. If serious concerns are raised, a more thorough investigation should be performed by journals, publishers, and institutions. These methods provide a systematic and reproducible way to assess the collected work of an author or group of authors. It is increasingly accepted that papers reporting on clinical studies may contain fraudulent or falsified data, often multiple papers by a single author or author group. Based on our experience assessing the research integrity of collections of papers by one author or author group, we present an approach to these investigations that combines published statistical methods with pragmatic assessment of study feasibility. This will help journals and publishers better identify groups of potentially untrustworthy studies.

Feasibility analysis of solar and wind energy-powered irrigation pumping systems using reanalysis data–A case of Thiruvananthapuram district in Kerala, southwest region of India

This study presents a feasibility assessment of solar photovoltaic and wind energy systems for irrigation at three locations (a coastal lowland location named A, a midland location B, and a highland location C) in Thiruvananthapuram district, Kerala, in India’s southwest region. The solar and wind potentials are determined using the National Solar Radiation Database and Modern-Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data sets, respectively. The technical analyses suggest that site B has the most solar energy potential, while site C has the highest wind energy potential. However, the economic feasibility study reveals that the only suitable location is site B, which has a 10-year simple payback time (SPT). The site has an annual solar energy potential of 1633.85 kWh/kWp, which is enough to pump 3921.24 kL of water to irrigate the majority of crops in one acre.

Least Square Method Analysis for Sales Prediction in the Re-Evaluation of Feasibility Study for Housing Development Project in Malang

Feasibility studies are essential tools used to assess the viability and potential success of a project or investment. These studies provide critical information that helps stakeholders make informed decisions by analyzing various factors such as costs, benefits, risks, and potential returns. One specific type of project that often undergoes feasibility evaluation is housing development. In many cases, the feasibility assessment of housing projects is typically conducted by estimating the number of units sold without necessarily examining actual sales data. This approach can lead to inaccuracies and misguided conclusions. To address this gap, our research aims to re-evaluate the investment feasibility of ongoing housing projects by incorporating actual sales data and predicting future sales figures. By doing so, we can provide a more accurate and reliable assessment of the project's viability. The findings from this re-evaluation indicate that the investment in housing development remains highly feasible. Key financial metrics support this conclusion: the project has a Payback Period (PP) of just 0.55 years, meaning the initial investment is recovered in a little over half a year. Additionally, the Net Present Value (NPV) stands at Rp 103,917,111,414, reflecting the project's substantial profitability. Furthermore, the Internal Rate of Return (IRR) is an impressive 81.73%, far exceeding typical investment benchmarks. Lastly, the Benefit-Cost Ratio (BCR) of 1.53 demonstrates that the benefits of the project significantly outweigh the costs, confirming its overall financial soundness. These results underscore the importance of using comprehensive data analysis in feasibility studies to ensure accurate and effective investment decisions.

The use of three-dimensional media in the shape of the Earth’s surface to optimize the knowledge of blind students in social science subjects

The aims of this research are to (1) produce three-dimensional (3D) media suitable for use and (2) analyze responses and learning outcomes for blind students who use 3D media in the Earth’s shape. The subjects of this study included 16 blind students in class VII SMPLB-A Gebang Putih Surabaya and SLBN Kalirejo Bojonegoro, East Java Province, Indonesia. The feasibility level of the media is based on assessments from learning media and material experts using validation sheets from media experts and material experts. They collect data on the responses of blind students using student response questionnaires. Collecting data on learning outcomes of blind students uses tests carried out through pre-test and post-test activities. The media feasibility data analysis technique uses a four-category Likert-type scale adopted from Mardapi. The responses of blind students were analyzed using a five-category Likert-type scale adopted from Sugiyono. Learning outcomes were analyzed using the n-gain test and paired sample t-test. The study results stated that 3D media in the form of the Earth’s surface received a feasibility assessment by learning media experts in the very feasible category. The blind students responded very well to using 3D media in the form of the Earth’s surface in social science subjects. In the aspect of knowledge in the form of learning outcomes, it has high effectiveness, and there is a significant difference between before and after applying 3D media in the shape of the Earth. Through 3D media, Blind students can experience visual experiences using 3D media. By holding and touching objects in 3D media, they can feel their shape, size, and texture.

Development and Testing of the Spinal Cord Injury Bladder and Bowel Control Questionnaire (SCI-BBC-Q).

Recovery of lower urinary tract (LUT) and lower gastrointestinal tract (LGIT) is a high priority for people with lived experience following spinal cord injury (SCI). A universally accepted validated patient-reported outcome (PRO) measure of the individual sensory and motor components of LGIT and LUT function, which allows tracking of recovery is lacking. To address this literature gap, the SCI Bladder and Bowel Control Questionnaire (SCI-BBC-Q) was developed. The SCI-BBC-Q was developed as a direct assessment of the micturition and defecation experiences of an individual with SCI with possible neurogenic LUT and LGIT dysfunction. The SCI-BBC-Q development process consisted of two phases, measure development and evaluation. Measure development was guided by a conceptual framework, review of existing instruments and literature, and an iterative process of item incorporation, review, feedback, and consensus revision. Evaluation included cognitive interviewing, and assessments of feasibility, reliability, and content validity. The final 6-item SCI-BBC-Q is a PRO, which assesses motor and sensory function related to micturition and defecation, requiring ~5 min to complete. Assessments of clarity of the instrument components with regard to understanding of what is being asked in the questionnaire, feasibility of administration, reliability, internal consistency, and agreement with proxy measures have demonstrated that the SCI-BBC-Q provides consistent, stable, and reproducible data. Significant correlations were found between SCI-BBC-Q scores and the anorectal motor and sensory components of the International Standards for the Neurological Classification of SCI. The SCI-BBC-Q is a practical and reliable method for baseline and ongoing evaluation of patients with neurogenic LUT and LGIT dysfunction, especially in the acute and subacute period when function is changing due to neurological plasticity. It is also appropriate for use in monitoring response to treatments related to neurological recovery.

Microvascular reactivity in anesthetized cats: feasibility and proof of concept study.

Assessment of feasibility and proof of concept study for microvascular reactivity in anesthetized cats. 12, adult, healthy, purpose-bred cats were included. Cats were anesthetized and instrumented with a perivascular ultrasound transit time flow probe around the main pulmonary artery, a femoral arterial catheter, a central venous catheter, and a laser Doppler flowmeter with a heating unit. After a 20-minute stabilization period, microvascular reactivity, hemodynamic variables, and arterial and central venous blood gases were measured during 3 phases: (1) baseline, (2) hemorrhage, and (3) isotonic crystalloid bolus. Hemorrhage was induced by atraumatic blood loss of 20 mL/kg over 20 minutes. An isotonic crystalloid bolus at 20 mL/kg was administered IV over 20 minutes. 6 cats were excluded from the analysis due to equipment errors or surgical complications. Microvascular reactivity decreased significantly after hemorrhage and remained below baseline after isotonic crystalloid bolus. Microvascular reactivity assessment is feasible in healthy anesthetized cats. Hemorrhage decreases microvascular reactivity, and the administration of an isotonic crystalloid bolus did not reverse these changes. However, the small sample size may limit the external validity of the results. This study demonstrated the feasibility of microvascular reactivity assessment in anesthetized cats. However, proper validation is warranted before clinical application.

Developing a Psychiatry Residency Program in a Low- and Middle-Income Country: Botswana's Experience.

Like many other low- and middle-income countries, Botswana has struggled to address the shortage of doctors, particularly specialists. In 2009, the country's first medical school offering an undergraduate medical program was established. A needs and feasibility assessment was conducted with relevant stakeholders to explore the need for specialty training programs in all medical school departments. As a result, three residency programs were established a year after the undergraduate program, but psychiatry was not included in this first crop of residency programs. Existing strengths in the university and healthcare systems were leveraged to successfully establish a four-year Master of Medicine residency program in psychiatry, which began in January 2020. The program aims to produce psychiatrists who are familiar with the local mental health needs. The first batch of students completed their training in December 2023. This paper reflects on and describes the development of a psychiatry residency program in Botswana and contributes a process grounded in educational program development models and educational theories that others can utilize. Botswana's experience may be helpful to other low- and middle-income countries, particularly in sub-Saharan Africa, that want to establish and run a locally developed residency program in psychiatry.

Global Dynamic Impression for Differentiating Between Epileptic and Psychogenic Nonepileptic Seizures: A Feasibility Study.

Medical personnel show difficulty in differentiating psychogenic nonepileptic seizures (PNES) from epileptic seizures (ES). The purpose of this study was to conduct an initial feasibility assessment of the global dynamic impression (GDI) principle and to evaluate its effectiveness in enabling the diagnosis of epileptic versus psychogenic seizures using video footage of events, even by untrained personnel METHODS: We based this study on video footage showing five videos of PNES and five ES videos. We asked physicians and nurses from the emergency department, internal medicine department, neurology department, and medical students to classify the videos before and after learning the GDI principle. The GDI principle is a simple clinical tool assuming repetitive movements with minimal dynamics in vector and frequency in motor PNES. A correct answer earned a score of 10 points, and a wrong answer a score of 0. Therefore, the questionnaire score could range from 0 to 100. A total of 108 medical personnel participated in the study. A total of 42 participants filled out the questionnaire before training-Group 1, and 36 participants filled out the questionnaire after training-Group 2; 30 participants filled out the questionnaire before and after the training-Group 3. The mean score of Group 1 was 55.23±17.83 versus 75.55±13.61 in Group 2 (p=0.0000001). The mean score of Group 3 was 53±17.8 compared to 78±12.9, before and after training, respectively (p=0.000001). A brief training on the GDI principle of various medical teams, even unskilled teams, significantly improves differentiating PNES from ES.

Health outcome priorities of people with multiple long-term conditions using the outcome prioritisation tool in the UK: A survey study and feasibility assessment.

The outcome prioritisation tool (OPT) is a simple tool to ascertain the health outcome priorities of people with MLTC. Use of this tool in people aged under 65 years with MLTC has not previously been investigated. This study aimed to investigate the feasibility of using the OPT in people with MLTC aged 45 years or above, in a multi-ethnic primary-care setting and describe the health outcome priorities of people with MLTC by age, clusters of long-term conditions and demographic factors, and to investigate any differences in prioritisation in light of the COVID-19 pandemic. This was a multi-centre cross-sectional study using a questionnaire for online self-completion by people aged 45 years or above with MLTC in 19 primary care settings across the East Midlands, UK. Participants were asked to complete the OPT twice, first from their current perspective and second from their recollection of their priorities prior to COVID-19. The questionnaire was completed by 2,454 people with MLTC. The majority of participants agreed or strongly agreed that the OPT was easy to complete, relevant to their healthcare and will be useful in communicating priorities to their doctor. Summary scores for the whole cohort of participants showed Keeping Alive and Maintaining Independence receiving the highest scores. Statistically significant differences in prioritisation by age, clusters of long-term conditions and employment status were observed, with respondents aged over 65 most likely to prioritise Maintaining independence, and respondents aged under 65 most likely to prioritise Keeping alive. There were no differences before or after COVID-19, or by ethnicity. The OPT is feasible and acceptable for use to elicit the health outcome priorities of people with MLTC across both middle-aged and older age groups and in a UK setting. Individual factors could influence the priorities of people with MLTC and must be considered by clinicians during consultations.

ECOLOGICAL MOMENTARY ASSESSMENT OF SUICIDE RISK: FEASIBILITY AMONG OLDER ADULTS WITH MEMORY CONCERNS

Abstract Given heightened suicide risk among older adults,, effective and timely risk assessment strategies are imperative to inform suicide prevention. Ecological momentary assessment (EMA) may help detect fluctuations in socioemotional suicide risk factors, including loneliness, depression, and suicide ideation (SI). The aim of the present study was to examine feasibility of an EMA battery for assessing momentary SI and socioemotional risk factors in older adults with subjective cognitive decline (SCD). Participants (n=27; M age=69; 82% female) were recruited from a larger study and were classified into “higher risk” (n=13) and “lower risk” (n=14) groups based on history of suicidal behavior or recent SI. Using an EMA app on their smartphone, participants were notified to complete four surveys daily for 14 days. EMA items included questions about SI, mood, loneliness, and cognitive concerns. After the survey period, participants completed validated “paper-and-pencil” assessments for comparison and provided feedback about app usability. On average, participants completed two-thirds of assigned surveys (M = 37, SD = 10) and completion rates did not vary significantly by suicide risk, (t(25) = 0.73, p >.05) or SCD severity (r = -.11, p >.05). Participants reported an easy and non-disruptive experience and provided helpful feedback regarding the structure of notifications, survey wording, and app interface. Additional demographic and psychosocial predictors of EMA response rate will be explored in regression models. Overall positive feedback suggests that EMA may be a feasible risk assessment method for use with older adults facing cognitive concerns.
