Can ChatGPT evaluate research quality?
Authors: Thelwall Mike
Published: April 2024

Purpose

Assess whether ChatGPT 4.0 is accurate enough to perform research evaluations on journal articles to automate this time-consuming task.

Design/methodology/approach

Test the extent to which ChatGPT-4 can assess the quality of journal articles using a case study of the published scoring guidelines of the UK Research Excellence Framework (REF) 2021 to create a research evaluation ChatGPT. This was applied to 51 of my own articles and compared against my own quality judgements.

Findings

ChatGPT-4 can produce plausible document summaries and quality evaluation rationales that match the REF criteria. Its overall scores have weak correlations with my self-evaluation scores of the same documents (averaging r=0.281 over 15 iterations, with 8 being statistically significantly different from 0). In contrast, the average scores from the 15 iterations produced a statistically significant positive correlation of 0.509. Thus, averaging scores from multiple ChatGPT-4 rounds seems more effective than individual scores. The positive correlation may be due to ChatGPT being able to extract the author’s significance, rigour, and originality claims from inside each paper. If my weakest articles are removed, then the correlation with average scores (r=0.200) falls below statistical significance, suggesting that ChatGPT struggles to make fine-grained evaluations.

Research limitations

The data is self-evaluations of a convenience sample of articles from one academic in one field.

Practical implications

Overall, ChatGPT does not yet seem to be accurate enough to be trusted for any formal or informal research quality evaluation tasks. Research evaluators, including journal editors, should therefore take steps to control its use.

Originality/value

This is the first published attempt at post-publication expert review accuracy testing for ChatGPT.
Comparison of serological and molecular methods for differentiation between genotype A and genotype B strains of small ruminant lentiviruses
Authors: Olech Monika , Kuźmak Jacek
Published: April 2024

Introduction

Small ruminant lentiviruses (SRLV) cause multisystemic, degenerative and chronic disease in sheep and goats. There are five genotypes (A, B, C, D and E), of which A and B are the most widespread. The purpose of this study was to evaluate the serotyping efficiency of the Eradikit SRLV Genotyping ELISA and the molecular typing efficiency of a newly developed nested real-time PCR targeting the long terminal repeat–gag (LTR-gag) region using samples from animals infected with subtypes of SRLV known to circulate in Poland.

Material and Methods

A total of 97 sera samples taken from 34 sheep and 63 goats were immunoassayed, and 86 DNA samples from 31 sheep and 55 goats were tested with the PCR. All ruminants were infected with known SRLV strains of the A1, A5, A12, A13, A16, A17, A18, A23, A24, A27, B1 and B2 subtypes.

Results

A total of 69 (80.2%, 95% confidence interval 71.6%–88.8%) out of 86 tested samples gave positive results in the PCR. In 17 out of the 86 (19.8%) samples, no proviral DNA of SRLV was detected. The differentiation between MVV (genotype A) and CAEV (genotype B) by PCR matched the predating phylogenetic analysis invariably. No cross-reactivity was observed. On the other hand, the proportion of samples genotyped the same by the older phylogenetic analysis and the Eradikit SRLV Genotyping ELISA was 42.3%. The test was unable to classify 40.2% of samples, and 17.5% of sera were incorrectly classified.

Conclusion

Our results showed that the Eradikit SRLV genotyping kit is not a reliable method for predicting SRLV genotype, while the nested real-time PCR based on the LTR-gag region did prove to be, at least for genotypes A and B.
A Regression Model of Dry Bulk Carriers’ Loading Time
Authors: Đelović Deda
Published: April 2024

Although optimization of Vessel Turnaround Time (VTT) is a well-known research problem and its importance has long been understood, research on dry bulk carriers VTT has no priority in the available literature. It is one of the initial motives of the author to write this paper. After a general theoretical introduction, this paper presents research on dry bulk carriers’ loading time, as a component with the dominant share in the total VTT. Through the research, a mathematical model of interdependencies between dry bulk carrier‘s loading time and selected independent variables is defined using a multiple linear regression model. Results of statistical significance tests confirmed that the best-fit regression model is the one which adequately describes the correlation between the dry bulk carrier‘s loading time and the following independent variables: cargo quantity (loaded), number of used cranes per vessel and loading process interruptions. The presented results establish important bases for the author’s further research in this field as well as reliable planning bases for cargo handling management processes at dry bulk cargo terminals where cargo loading/unloading to/from vessels is realized by gantry cranes and/or mobile harbour cranes.

Published: April 2024

Background:

Congenital chloride diarrhea (CCD) is a rare autosomal recessive condition characterized by lifelong watery diarrhea. CCD is challenging to diagnose because of its severe clinical presentations and differentials. Therefore, it is crucial to be diagnosed early and receive appropriate management as it causes early death if left untreated or due to complications.

Case Report:

A Saudi newborn baby boy was passing a large amount of urine through the anal canal and was otherwise healthy. He was referred to our center with a high suspicion of a colovesical fistula. Diagnosed with CCD by the exclusion of fistula after confirmation with contrast study.

Conclusion:

This case highlights an unusual presentation of CCD mimicking a colovesical fistula. To the best of our knowledge, no similar case has been reported in the literature, and we believe this is the first Saudi case of CCD mimicking a colovesical fistula. It underscored the diagnostic challenges of this rare disorder and emphasized the importance of early recognition and accurate diagnosis to prevent such complications.

Authors: Aydoğan Coşkun Burcu
Published: April 2024

The aim of this review is to provide information concerning the types of chestnut shells (inner and outer), their compositions and bioactive compounds, as well as to mention industrial peeling applications. These shells are comprised of high-valued natural active compounds, such as polyphenols (phenolic acids, flavonoids, tannins, hydroxycoumarins -scopoletin, scoparone-), pigments (melanin) and minor compounds (minerals, dietary fiber, vitamin C and E, essential amino acids and fatty acids). The total phenolic acids and flavonoid content of C. sativa shell were ranged between 119.17-223.62 mg/kg db and 330 – 503 mg CE/g. It is also a good source of vitamin C with reported levels of 15.57 and 28.97 mg AA/100 mg db in water and ethanol extracts, respectively. The shells are used as food additives due to their colorant, antioxidant and antimicrobial properties. The shells are exposed by the peeling process applied to obtain the fruit without the shell which is mainly used. The most frequently used technique in chestnut peeling is the Brulage peeling method. However, in this technique, used peeling mechanism is insufficient to obtain both inner and outer shells separately at the same time. Moreover, further research is needed to obtain the shells individually, to analyse each shell in detail, and to increase the industrial use of shells.

Published: April 2024

Pregnancy and delivery are physiological conditions that are marked by abrupt alterations to hormones, immunological and molecular characters. The current study aimed to evaluate oxytocin (OT), prolactin (PRL), cortisol and insulin growth factor-2 (IGF-2) levels as physiological biomarkers; programmed cell death protein-1 (PD-1), programmed cell death ligand-1 (PD-L1),interleukin-6 (IL-6) as immunological biomarkers, and single nucleotide polymorphisms (SNPs; rs53576 and rs2254298) of oxytocin receptor gene OXTR as molecular factors in samples of Iraqi women undergoing caesarean section (CS) and normal delivery (ND). Blood samples were collected from 96 pregnant women at term with ages ranging between 16-43 years. Regarding the physiological biomarkers, the study findings indicated that the change in OT, cortisol and IGF-2 between CS and ND groups was not significant, While the PRL level indicated a highly significant (P≤0.001) decrease in the CS group, especially in comparison with the ND group. Immunological biomarkers demonstrated a significant (P≤05) elevation for PD-1 as well as for PD-L1 in the CS group as compared to the ND group. However, PD-1/PD-L1 ratio revealed a high significant (P≤0.001) rise in CS compared with ND. The IL-6 results revealed a significant (P≤0.001) reduction in the CS groups compared to the ND group. And  regarding the SNP of OXTR (rs53576), the findings revealed no notable association in genotypes CC, TC and TT between both groups. In addition, the mutant C allele and the wild T allele revealed no significant association between CS and ND groups [OR=1.26 (0.68-2.3%)].  The SNP results of OXTR (rs2254298) showed a high positive association (P≤0.001) in genotypes GG, AG and AA between CS and ND groups. Also, the mutant G allele and the wild A allele revealed high significance (P≤0.001) between both groups [OR=5.3 (2.8-9.76%)].

Challenges Faced by Social Workers Rendering Foster Care Services in the John Taolo Gaetsewe District, Northern Cape Province
Authors: Mosala MK , Wilson Lizane
Published: April 2024

Foster care services are in high demand in South Africa because of the significant number of children in need of care. Reasons for this include the death of biological parents, abuse, neglect, incarceration of parents, parents abandoning their children, and even disappearance of parents. The recent COVID-19 pandemic has worsened this situation. The demand for foster care is putting strain on the delivery of social work services to this vulnerable group. Social workers tasked with implementing the foster care process experience operational impediments and emotional strain, creating an implementation challenge. In examining these challenges, the ecological perspective provides a suitable theoretical framework. This qualitative research study is underpinned by an exploratory design and semi-structured interviews have been conducted to gather primary data. Eight participants have been purposively selected, and the data has been analysed using thematic analysis. Findings suggest that the challenges social workers face fall into three categories: operational obstacles, emotional challenges, and non-adherence to foster care values and principles. Policies and practices are recommended to address the identified challenges to ensure that social workers are empowered to implement foster care services that are child-centred and needs-based.

Eigenvalue Interlacing of Bipartite Graphs and Construction of Expander Code using Vertex-split of a Bipartite Graph
Authors: Manickam Machasri , Desikan Kalyani
Published: April 2024

The second largest eigenvalue of a graph is an important algebraic parameter which is related with the expansion, connectivity and randomness properties of a graph. Expanders are highly connected sparse graphs. In coding theory, Expander codes are Error Correcting codes made up of bipartite expander graphs. In this paper,  first we prove the interlacing of the eigenvalues of the adjacency matrix of the bipartite graph with the eigenvalues of the bipartite quotient matrices of the corresponding graph matrices. Then we obtain bounds for the second largest and second smallest eigenvalues. Since the graph is bipartite, the results for Laplacian will also hold for Signless Laplacian matrix. We then introduce a new method called vertex-split of a bipartite graph to construct asymptotically good expander codes with expansion factor D/2 < alpha  < D and epsilon < 1/2 and prove a condition for the vertex-split of a bipartite graph to be k-connected with respect to the second largest eigenvalue: Further, we prove that the vertex-split of G is a bipartite expander. Finally, we construct an asymptotically good expander code whose factor graph is a graph obtained by the vertex-split of a bipartite graph.

Let G be any graph. A sequence L = (w1, w2, ..., wk) of distinct vertices of G is called a legal sequence if NG[wi]\i[−1j=1NG[wj ] ̸= ∅ for each i ∈ {2, ..., k}. A legal sequence L is called a legal hop independent sequence if dG(wi, wj ) ̸= 2 for each i ̸= j. The maximum length of a legalhop independent sequence in G, denoted by αℓh(G), is called the legal hop independence number of G. In this paper, we initiate the study of legal hop independent sequences in a graph. Weinvestigate its relationships with the hop independence and grundy domination parameter of a graph, respectively. In fact, the legal hop independence parameter is at most equal to the grundy domination (resp. hop independence) parameter on any graph G. Moreover, we derive some formulas or bounds of this parameter on some families of graphs, join, and corona of two graphs.

Published: April 2024

This paper introduces the concept of the direct product of sets that involve Fermatean neutrosophic elements in structures called INK-algebras. It defines terms like the direct product of Fermatean neutrosophic INK-ideals in INK-algebras and Fermatean neutrosophic sets (FNSs), Fermatean neutrosophic INK-ideals (FNINK-Is), and Fermatean neutrosophic closed INK-ideals (FNCINK-Is). The proof of theorems illustrating the relationships between these ideas is included in the paper. It also defines the INK-sub algebra embedded in an INK-algebra and gives a theorem elucidating the connection between the direct product of Fermatean neutrosophic INK-ideals and the images of these sub-algebras. In essence, the paper investigates and establishes connections between different mathematical ideas concerning INK-algebras and FNSs.
The Block Topological Space and Block Topological Graph Induced by Undirected Graphs
Authors: Macaso Justine Bryle , Balingit Cherry Mae
Published: April 2024

Let $G=(V(G),E(G))$ be a simple undirected graph. A \textit{block} of $G$ is a maximal connected subgraph of $G$ that contains no cut-vertices \cite{eric}. The family of vertex sets of blocks of $G$ generates a unique topology. In this paper, we formally define the topology generated by the family of blocks in a graph called the \textit{block topological space}. Moreover, we characterize and describe some special attributes of the block topological space. Finally, we associate a corresponding graph from a given block topological space by defining the \textit{block topological graph}.
THE USE OF CULTURAL AND ENVIRONMENTAL HERITAGE IN EDUCATIONAL CONTEXTS BETWEEN SPACES, IDENTITIES, ATTITUDES, AND COGNITIVE WELL-BEING
Authors: Nuzzaci Antonella
Published: April 2024

The paper explores some links between educational research, the use of cultural and environmental heritage and education, where it is possible to combine knowledge, disciplines, and skills to strengthen the cultural profile of the school population, but also to bring about important changes in attitudes and behavior. The world's cultural and environmental heritage, which collects the traces of extraordinary but also tragic events in human history, can act as a unifying force for peaceful coexistence for the whole of humanity, enabling future citizens to participate in democratic debate and make informed choices about the social challenges they face. It therefore contributes not only to the development of knowledge, but also to the ability of children, young people, and adults to understand contemporary problems by placing them in human, social, environmental, historical, and cultural contexts that help them to live. For cultural heritage to contribute to the recovery of knowledge, researchers, teachers, and operators must be able to share a solid research background that allows them to address the various issues relating to the quality of the experiences of use carried out in school contexts, with the aim of improving the learning processes of users. In fact, the cultural and environmental resources of the territory can only be a real methodological resource for improving cognitive well-being and the overall quality of education at all levels if they are seen as useful tools for different types of learning (cognitive, social, etc.) and not as general educational tools. The paper therefore questions the use of cultural and environmental heritage in education and its adequacy with respect to learning conditions, pausing to consider also the role played by attitudes to fruition, highlighting those elements and dimensions that can contribute to redefining the relationship between education, goods, and environment, in the idea of strengthening interpretative repertoires in educational contexts.

Background/Objective: In general, pandemic conditions require intensive and urgent intervention in terms of health care. This also negatively affects the physical and mental health of health workers. The aim of this research is to
identify the compassion fatigue of health workers working in COVID-19 services. Methods: This descriptive study was conducted on health workers (nurses, physicians) working in COVID-19 services of. This research was approved by
the Firat University's Non-Interventional Research Ethics Board (2020/16-26). As a result of the power analysis, the sampling quantity for health workers was identified as 310 in the study. All of the involved health workers gave
written and oral informed consent before participating in this research. In addition to descriptive statistical methods, ANOVA and Student t-tests were used. Data from the study was collected using Personal Information Form and
compassion fatigue-short scale (CF-short scale) through a face-to-face interview. Results: The average age of the health workers involved in the study was 29.79±6.73, and 71.6% (n=222) were nurses and 64.2% (n=199) were women.
The secondary trauma score of health workers is 24.50±10.45, occupational burnout score is 45.69±16.64 and total CF-short scale score is 70.19±25.13. The status of contact with the patient with COVID-19, the status of receiving
psychological help during the pandemic was found to show statistically significant differences according to the CF-short scale scores, and the dimensions of the subgroup. Conclusion: COVID-19 disease causes health workers to show
more intense mental symptoms such as trauma and burnout. Supporting the coping mechanisms of health workers, especially during pandemic periods, will be effective in protecting their psychosocial health.

Published: April 2024

Modern finans teorisinin köşe taşlarından biri olan Etkin Piyasa Hipotezi, piyasada mevcut olan tüm bilginin kullanılması suretiyle piyasanın üzerinde getiri elde edilemeyeceğini öne sürmektedir. Bununla birlikte finansal piyasalarda yapılan çalışmaların birçoğu, yatırımcıların bazı dönemlerde normalin üzerinde getiri elde ettiğini gösteren bulgular ortaya koymaktadır. Etkin Piyasa Hipotezi ile çelişen ve bazı dönemlerde elde edilen getirilerin ve katlanılan riskin diğer dönemlere göre farklılaştığını ifade eden etkiler takvim anomalileri olarak tanımlanmaktadır. Takvim anomalileri içerisinde genellikle günlere, aylara ve yıllara göre farklılaşan etkiler incelenmektedir. Bu çalışmada Bitcoin ve Ethereum kripto para piyasasında takvim anomalilerinin incelenmesi amaçlanmıştır. Bu kapsamda haftanın günü, yılın ayı ve yıl dönümü anomalileri kukla değişken ile temsil edilerek Bitcoin ve Ethereum için belirlenen TGARCH(1,1) ve EGARCH(2,2) modeline ilave edilmiş ve Bitcoin için 18.07.2010 – 17.05.2023 dönemini, Ethereum için 10.03.2016 – 17.05.2023 dönemini kapsayan günlük veriler üzerinden analiz yapılmıştır. Çalışma sonucunda elde edilen bulgular, Bitcoin ve Ethereum piyasasında haftanın günü ve yılın ayı anomalilerinin bulunduğunu göstermektedir.
