Response to Comment on Electric Multipole Moments for Some First-Row Diatomic Hydride Molecules [Commun. Theor. Phys. 38 (2002) 256]

The comment of Guseinov is irrelevant and also unjust. In contrast to his comment, we show that the obtained electric multipole moment values for some first-row diatomic molecules are original and better than his values (I.I. Guseinov, E. Akin, and A.M. Rzaeva, J. Mol. Struct. (Theochem) 453 (1998) 163) with respect to Hartree-Fock values. Moreover, it must be noted that all the formulas are cited in our paper (M. Orbay and T. Ozdogan, Commun. Theor. Phys. (Beijing, China) 35 (2001) 585) and corrigendum (M. Orbay and T. Ozdogan, Commun. Theor. Phys. (Beijing, China) 37 (2002) 768).

Exponential type orbitals with hyperbolic cosine function basis sets for isoelectronic series of the atoms Be to Ne

Abstract Exponential type orbital with hyperbolic cosine basis functions, proposed recently for Hartree–Fock–Roothaan calculations of neutral atoms, are studied in detail for the calculations of isoelectronic series of atoms from Be to Ne. Calculations are performed for the neutral and the first 20 cationic members of the isoelectronic series of each atom in its ground state. Three of the most popular exponential type orbitals (Slater type functions, B functions and ψ ( α ) functions with α = 2) are combined with modified hyperbolic cosine function cosh( βr + γ ) to improve the basis function quality within the minimal basis sets framework. Performances of the basis functions are compared with each other by using the same number of variational parameters in them. The obtained results are also compared with numerical Hartree–Fock and extended Slater type basis set results. The presented accuracy of the minimal basis descriptions of atomic systems supports the usage of these unconventional basis functions in electronic structure and property calculations.

Building Journal Impact Factor Quartile into the Assessment of Academic Performance: A Case Study.

This study aims to provide information about the Q Concept defined as the division of journal impact factors into quartiles based on given field categories so that the disadvantages resulting from the direct use of journal impact factors can be eliminated. While the number of Original articles published in the Web of Science (WoS) database-indexed journals like SCI, SSCI and A&HCI is an important indicator for research assessment in Turkey, neither the journal impact factors nor the Q Concept of these papers have been taken into account. Present study analyzes the scientific production of the Amasya University researchers in journals indexed in WoS database in the period 2014-2018 using the Q concept. The share of publications by Q category journals as well as the average citations received by the works from Amasya University were compared to the average situation in Turkey and other different countries in the world. Results indicate that the articles published by Amasya University researchers were mostly published in low impact factor journals (Q4 journals) (36.49%), in fact, only a small share of papers were published in high impact journals (14.32% in Q1 journals). The share of papers published in low impact journals by researchers from Amasya University is higher than the Turkish average and much higher than the scientific leading countries. The average citations received by papers published in Q1 journals was around six times higher than papers published in Q4 journals (8.92 vs. 1.56), thus papers published in Q1 journals received 30.02% citations despite only 14.32% of the papers was published in these journals. The share of papers published which were never cited in WoS was 27.48%, increasing from 9.68% in Q1 to almost half (48.10%) in Q4. The study concludes with some suggestions on how and where the Q Concept can be used.

Evaluation of two‐center overlap and nuclear attraction integrals over Slater‐type orbitals with integer and noninteger principal quantum numbers

Abstract A general formula has been established for the expansion of the product of two normalized associated Legendre functions centered on the nuclei a and b . This formula has been utilized for the evaluation of two‐center overlap and nuclear attraction integrals over Slater‐type orbitals (STOs) with integer and noninteger principal quantum numbers. The formulas given in this study for the evaluation of two‐center overlap and nuclear attraction integrals show good rate of convergence and great numerical stability under wide range of quantum numbers, orbital exponents, and internuclear distances. © 2001 Wiley Periodicals, Inc.

Short, But How Short? Analysis of Educational Research Titles

In academic performance assessments, citations and citation-based metrics play a pivotal role. Among the elements that influence the success of an article, the title stands out as the first point of contact for editors, reviewers, and readers. Consequently, the title length-citation relationship is an extensively studied issue. While the dominant language used in the databases is English, rhetorical discourses are dominant in the non-English literature about the appropriate length of titles. This study investigates the relationships between title lengths, article downloads, and citations for educational research articles in the Turkish context. Specifically, it focuses on articles indexed in TRIndex and Google Scholar that were published in the Turkish Journal of National Education between 2010 and 2015. The parametric and nonparametric tests using different approaches (median and quarterly classification, correlation analysis) reveal a low negative correlation between title lengths and citations and downloads, a moderate positive correlation between downloads and citations, and a high positive correlation between the citations in the databases. It has been observed that the articles with short titles are read and cited more than the ones with longer titles. These findings align with previous research conducted in the English language. The results suggest that the optimal title length for educational research coincides with “ the magical number seven, plus or minus two,” often referred to as Miller’s Law, which represents the number of objects an individual can retain in their short-term memory. The study provides practical implications for authors, editors, and researchers on optimizing title length for better visibility and impact.

What does Hirsch index evolution explain us?A case study: Turkish Journal of Chemistry

The evolution of Turkish Journal of Chemistry’s (TURK J CHEM) Hirsch index (h-index) over the period 1995-2005 is studied and determined in the case of the self and without self-citations. It is seen that the effect of Hirsch index of TURK J CHEM has a highly positive trend during the last five years. It proves that TURK J CHEM is improving itself both in quantity and quality since h-index reflects peer review, and peer review reflects research quality of a journal.

Educational Research Review From Diverse Perspectives: A Bibliometric Analysis of Web of Science (2011–2020)

This study aims to reveal the bibliometric characteristics of publications on educational research from diverse perspectives, including the level of national-international collaborations, the percentage change in open-access papers, and interactions with other disciplines. Through bibliometric analysis, the data were collected from Web of Science (WoS), “Education and Educational Research (E&ER),”“Psychology, Educational (PE),”“Education, Special (ES)” and “Education Scientific Disciplines (ESD)” categories, during 2011 to 2020. The findings suggest that the number of publications in each category and the percentage of open-access publications have increased regularly. However, it was observed that categories, especially the ES category, were partially falling behind, as compared to the growth in WoS; while the ES and the PE categories were the highest regarding national-international collaborations over time. Both collaboration levels were the highest in the E&ER category. It was concluded that the multi-authorship trend has rapidly increased, the number of references has regularly increased, and specifically, the PE category has been distinguished from others in terms of the references used. Meanwhile, the change over time in the aggregate impact factor, calculated for each category as a measure of the widespread impact of the studies, pointed to inflation. The results show that educational research is becoming more organized and international, while less fragmented. Moreover, the findings support that educational research is interdisciplinary in essence and diverse in content.
