The document discusses author level metrics and how they are used to measure the impact of individual authors. It defines author level metrics as citation metrics that measure the bibliometric impact of individual researchers. It also discusses different types of author level metrics, including article-level metrics, journal-level metrics, h-index, i10-index, g-index, and altmetrics. Finally, it discusses tools that can be used to measure author metrics, such as Google Scholar, Web of Science, Scopus, and Publish or Perish.

Journal-level metrics
Metrics have become a fact of life in many - if not all - fields of research and scholarship. In an age of information abundance (often termed ‘information overload’), having a shorthand for the signals for where in the ocean of published literature to focus our limited attention has become increasingly important.
Research metrics are sometimes controversial, especially when in popular usage they become proxies for multidimensional concepts such as research quality or impact. Each metric may offer a different emphasis based on its underlying data source, method of calculation, or context of use. For this reason, Elsevier promotes the responsible use of research metrics encapsulated in two “golden rules”. Those are: always use both qualitative and quantitative input for decisions (i.e. expert opinion alongside metrics), and always use more than one research metric as the quantitative input. This second rule acknowledges that performance cannot be expressed by any single metric, as well as the fact that all metrics have specific strengths and weaknesses. Therefore, using multiple complementary metrics can help to provide a more complete picture and reflect different aspects of research productivity and impact in the final assessment. ( Elsevier)
The presentation discusses about a Thesis, Research paper, Review Article & Technical Reports: Organization of thesis and reports, formatting issues, citation methods, references, effective oral presentation of research. Quality indices of research publication: impact factor, immediacy factor, H- index and other citation indices. A verbal consent of Prof. Dr. C. B.

Predatory Publications and Software Tools for IdentificationSaptarshi Ghosh
Journals that publish work without proper peer review and which charge scholars sometimes huge fees to submit should not be allowed to share space with legitimate journals and publishers, whether open access or not. These journals and publishers cheapen intellectual work by misleading scholars, preying particularly early career researchers trying to gain an edge. The credibility of scholars duped into publishing in these journals can be seriously damaged by doing so. It is important that as a scholarly community we help to protect each other from being taken advantage of in this way.
In academia, the pressure to publish is high and the competition intense. This can lead authors to follow unethical publication practices, such as salami slicing, duplicate publication, and simultaneous submission. This slide deck explains these malpractices and shares tips on how authors can avoid them.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. Author level metrics is a system/standard for measuring
the authors or evaluation of authors. Author-level
metrics are citation metrics that measure the bibliometric
impact of individual authors, researchers, academics, and
scholars. Other metrics originally developed for academic
journals can be reported at researcher level, such as the
author-level eigenfactor and the author impact factor.

Benefit of Author Level Metrics
5. Author level Metrics can be categorized in to
Article-level metrics
Journal-level metrics
H-index, i10-index, g-index, Altmetrics and others
Scientometrics
Category
6. There are several measures of author impact. They include
Total number of publications
Total number of citations for all publications
Average number of citations
Number of citations for a particular publication
Number of citations for a particular period
Number of reading/visit
Number of downloads
Number of request for the articles
Article Level Metrics
7. There are several ways to measures the Journal
Journal Impact Factor
SCImago Journal Ranking
And others
Journal Level Metrics
8. Journal impact factors are found in Journal Citation
Reports (JCR). JCR is a unique database which is used
to determine the relative importance of journals within
their subject categories.
An impact factor is one measure of the quality of a
journal. This is calculated by the number of citations
received by the journal, from other journals within the
database.
Journal Impact Factor
Number of citation received by “X” Journal in “A” the year
Journal Impact Factor =
Number of article published by same “X” Journals in previous two years of “A”
9. Five things to know about impact factors
Not all journals have impact factors. They must be
indexed in the database like Web of Science to have
an impact factor
A journal has only one impact factor, but it may be
listed in more than one category
A journal impact factor should not be looked at in
isolation, but in comparison to other journals in the
same category
Impact factors vary across disciplines
A five-year impact factor may also be used in some
disciplines.
Journal Impact Factor
10. SCImago journal Ranking
SCImago Journal uses Scopus database to compare
journals. It is freely available on the web. The Journal
Rankings tab allows you to retrieve a list of journals
within a subject area or category.
SCImago Journal Rank (SJR indicator) is a measure of
scientific influence of scholarly journals that accounts for
both the number of citations received by a journal and
the importance or prestige of the journals where such
citations come from. A journal's SJR is a numeric value
indicating the average number of weighted citations
received during a selected year per document published
in that journal during the previous three years. Higher
SJR values are meant to indicate greater journal
prestige.
SJR is updated twice a year.
11. h-index
The h-index is a popular metric. It was developed by J.E.
Hirsch, a physicist at the University of California.
An index to quantify an individual's scientific research
output i.e., 'An entity has an h-index value of y if the
entity has y publications that have all been cited at
least y times'. (Hodge & Lacasse). Thus, the h-index
reflects both the number of publications and the number
of citations per publication. The index is designed to
improve upon simpler measures such as the total
number of citations or publications. The index works
properly only for comparing scientists working in the
same field; citation conventions differ widely among
different fields.
12. i10-index
The i10-Index, used solely by Google Scholar, was
introduced in July 2011. It calculates the number of
academic publications an author has written that have at
least ten citations from others. This is one way to gauge
the productivity of an author.
i10-Index = the number of publications with at least 10
citations.
13. g-index
Harzing's Publish and Perish Manual explains the g-index
is calculated based on the distribution of citations
received by a given researcher's publication.
A set of papers has g-index , if g is the highest rank such
that the top g papers have together at least g2 citations.
Also means that, the top g+1 papers have less than
(g+1)2 papers.
For example: If an author is having g-index of 20 means
that author has published at least 20 articles
that combined have received at least 400 citations.
One of the main advantages of the g-Index is the
inflated values of this index helps give credit to lesser
cited or non-cited work whilst attributing credit for
highly-cited papers.
14. Altmetrics
'Altmetrics is the creation and study of new metrics
based on the Social Media Tools for analyzing, and
informing scholarship'
Altmetrics (alternative metrics) has emerged due to the
limitations of traditional citation metrics such as the
impact factor, providing complementary evidence
of research impact. 'Altmetrics' is a very broad category
that includes diverse measures that can range from a
news story to a Facebook like.
If you have an account or profile with any social network
service (Flickr, Facebook, Academia.edu, etc.), you will
be familiar with 'likes', 'downloads', 'views', 'shares' and
similar indications of interest in your activity.
15. Altmetrics
Pros Cons
Immediacy
Unlike citations, which take time
to accumulate, impact can be
assesed in real-time
Potential for manipulation
The openness of social media
provides the opportunity for artifical
inflation of figures
Track impact outside the formal
publishing network
Can measure the impact of a
wider variety of scholarly
communication channels such as
datasets, presentation slides,
pre-prints, videos and websites
Popularity of social media services
Comparisons of figures from a
specific tool (e.g. Twitter) for
material published at different times
can be affected by fluctuations in
the number of users
Assess reach beyond scholarly
citing community
Capture evidence of engagement
in broader society e.g.
practitioners, undergraduates,
general public including the
impact of influential but uncited
work
Acceptance
These measures and their role in
measuring impact are evolving and
have differing levels of acceptance
in the scholarly community
16. Publish or Perish is a software program created by
Anne-Wil Harzing of University of Melbourne. The
program analyses your Google Scholar raw
citations and presents you with a variety of
statistics, including
• total number of citations
• total number of references
• average number of references
• h-index
• g-index
Publish or Perish
17. Degree of Collaboration
Lotka’s Law and others
Scientometrics
18. The degree of collaboration is defined as the ratio of the
number of collaborative research papers to the total
number of research papers in the discipline during a
certain period of time(Subramanyam). It is expressed as
Nm
C =
Nm+Ns
where; C is the degree of collaboration in a discipline. Nm
is the number of multi-authored research papers in the
discipline published during a year. Ns is the number of
single authored research papers in the discipline published
during a year.
Degree of Collaboration
19. Lotka’s law describes the frequency of publication by authors in
any given field. It states that the number of authors
making ’x’ contributions in a given period is a fraction of the
number making a single contribution, the
formula ”1/xa” where a nearly always equals two, i.e., an
approximate inverse-square law, where the number of authors
publishing a certain number of articles is a fixed ratio to the
number of authors publishing a single article. As the number of
articles published increases, authors producing that many
publications become less frequent. There are 1/4 as many
authors publishing two articles within a specified time period as
there are single-publication authors, 1/9 as many publishing
three articles, 1/16 as many publishing four articles, etc. Though
the law itself covers many disciplines, the actual ratios involved
(as a function of 'a') are discipline-specific.
The general formula says XnY=C or Y=C/Xn, where X is the
number of publications, Y the relative frequency of authors
with X publications, and n and C are constants depending on the
specific field (n~2).
Lotka’s Law
20. Requirement for Author Metrics
To assess the we need Digital Author ID like;
• ORCID ID
• Scopus ID
• Researcher/ Publon ID
• Google Scholar ID
• Others
21. Tools for Author Metrics
There are many tools to assess the Author Metrics
• Google scholar
• Web of Science
• Scopus
• Publish or perish
• And others
22. Conclusion
It is worth remembering that the key measuring tools
(databases) only gather data from the journals they
index.
Author naming inconsistencies can lead to missed
citations
Citation culture varies across discipline and not be
comparable
Publication Culture
Researcher career is have different stages
Author metrics Impact does not always equal to
excellence
Scholarly communication is evolving beyond the
citations
Factors affecting citation rates include type of article (eg
review articles are more highly cited than editorials),
Language, Refutation, Citation bias or self-citation,
Subject area, Publication schedule, Journal reputation
