Which is the Most useful topic in LIS field?
Relevant answer
Answer
Hi,
It seems that the most valuable for research in LIS studies is bibliometrics. The reason for this is that within this vast field you could study every area or subarea in LIS, and use a quantitative research method.

RISs are large surfaces without separate antennas and are considered as a whole, while LISs are composed of small antennas with limited capabilities. (Is this understanding right?)
What is the specific difference between RIS and LIS in terms of the phase shifts they induce to their received signal?
Can we assume the same phase shift from both RIS and LIS?
What is the difference in modeling their channel, mathematically? (What I see, both are modeled with a coefficient and a specific phase shift)
Relevant answer
Answer
This is a hard question to answer because the terms mean different things to different people.
Originally, the term LIS was used to describe large active antenna arrays, like massive MIMO but much larger:
Hence, a LIS generates, transmits, and receives signals. The arrays are not only large but also consisting of very small elements, giving an almost continuous control over the electromagnetic waves over the surface.
In contrast, a RIS is receiving a signal from another location and scatters it in a controllable way. It is like a (semi-)passive large array.
Unfortunately, some researchers have used LIS as more-or-less synonymous with RIS, which causes confusion.

We think the low level of cross-disciplinary collaboration in LIS contradicts the interdisciplinary nature of LIS highlighted in the literature, at least in the four countries we have analyzed: France, Germany, Spain and United Kingdom:
Urbano, C., Ardanuy, J. "Cross-disciplinary collaboration versus coexistence in LIS serials: analysis of authorship affiliations in four European countries." _Scientometrics_ (2020). https://doi.org/10.1007/s11192-020-03471-z
Relevant answer
Answer
Dear Cristóbal, thanks for the data and this discussion thread.
Probably a clear differentiation between interdisciplinarity and cross-disciplinarity is needed. In any case, as other social sciences, co-authorship is low as research groups are small, the field has a higher practitioner orientation, and costly instrumentation, labs and equipment is not needed. This way, one researcher in LIS can write a paper alone, only with access to some databases, something impossible in other disciplines. I believe this affects cross-disciplinarity, as this standalone researcher will select a core journal of his/her discipline to publish.
Moreover, we need to take into account not only co-authors from different disciplines (through affiliation data) but cross-disciplinarity at the journal-level (thematic classification of journals where authors publish).
Medicine is a Metropoli, Humanities is a small cottage in the forest, and Social Sciences stays in the middle. Some social sciences closer to the city, while other close to the town. Unfortunately, LIS is closer to the town.
Theoretical aspects of information Sciences underlie on multitude of other disciplines, but those communities do not use our vocabulary, neither read our contributions, in the same way as we do not read contributions by them. iSchools was a temptative for teaching, but not reflected in research.
Your contribution is very timely and insightful, I will follow with interest!
All the best, y un fuerte abrazo :)

What would be the PDF of the finite sum (i.e., the sum of N product terms) of the product of two independent but non-identically distributed Rayleigh random variables? Does someone know what the PDF would be (a paper, book, etc. where I can find it)?
The question can be formulated as
\sum_{n=1}^{N} { X_n Y_n },
where X_n and Y_n are independent but non-identically distributed Rayleigh random variables.
Is there a closed-form for this PDF?
Many thanks in advance!
Relevant answer
Dear Felipe,
I found some literature that can help you solve your problem.
- There is a closed form solution for the pdf of a summation of random Rayleigh variables:
- in addition there is a closed form solutions for a pdf pf a multiplication of Rayleigh variables:
There is only one step if you combine the two solutions then you can get the required solution which is the sum of products of the Rayleigh random variable.
This may considered as a methodology for the solution.
Best wishes

Is it plausible to model the effective phase shifts applied by all LIS reflecting elements as uniformly distributed random variables?
Relevant answer
Answer
The distribution of the error will depend on how it is generated. If you take the optimal phase and then quantize it using a uniform quantizer, then it seems likely that the error will be uniformly distributed (if the all phase values are equally likely).

I’ve just been thinking about where library science has been, where library science research is today, and where library science research is heading in the future.
I wonder what big problems have been solved, what big problems are we working on today, and what problems can we dream to solve through future library science research?
Relevant answer
Answer
Library Science is the study of librarianship. The future of Library Science is simply digital libraries where information can be stored and retrieved electronically; where there will be no access to brick-and-mortar libraries.

Backround research on climate reconstructions around pluvial lakes in the Great Basin, I am finding that a loose correlation between later glacial maxima for alpine glaciers in the southerly portions of western North America, as the continental ice sheets retreat. The alpine glacier retreats then correspond loosly in time to the rise in pluvial lake levels. How does this all relate to the rising sea levels with the retreat of continental ice, especially LIS? Does this increase in sea level in the Pacific have relation to what seems like an increase in moisture seen from the Sierra Nevadas, across the Great Basin, to the southern edge of the Yellowstone ice cap?
Are there any studies that link these? I find it interesting, and relates to my research via lake level to the Chewaucan Basin and the local biome ~15-9 ka.

LIS experts have been making efforts to calculate Return of Investment (ROI) in public libraries across the world. Is there any standard format to measure ROI of academic libraries OR what parameters can be enveloped while measuring ROI in academic libraries?
Relevant answer
Answer
Another well-known resource is: Oakleaf, M. (2011). What’s the Value of an Academic Library? The Development of the ACRL Value of Academic Libraries Comprehensive Research Review and Report. Australian Academic & Research Libraries, 42(1), 1-13.
That said, the concern I have with articles on this topic (ROI) is that they tend to provide a methodology based on a library perspective rather than the perspective of senior management within a university, i.e. the target audience.
To demonstrate the library's ROI, you have to first link anything you measure to the university's strategic outcomes / goals. In other words, how does what the library does support the goals of the institution? Secondly, and very importantly, you need to use examples that make sense to your target audience, who are obviously not librarians.
A classic (poor) example is to provide lots of statistics of how many training sessions have been done for X number of students in information literacy. Those statistics are meaningless to a university administrator because they do not tell him / her what the end benefit to the student (and the university) has been to provide that training. However, adding a statement such as "To see the benefit providing these services can make to the retention and success of our students, the following comments have been reproduced from [name of your source]", explains WHY this training adds value to the university.

Subject analysis is a fundamental and cruicial step in the identification of  the subject of a work or resource. What steps are part of the subject analysis process? What cognitive aspects are included in subject analysis by the cataloger, indexer or classifier?
Relevant answer
Answer
To this question:  What steps are part of the subject analysis process?
In my experience, the cataloguer must read and revise the content of the work to define the main and related subects, as well as those which must not be included as a subject.
 On this other one: What cognitive aspects are included in subject analysis by the cataloger, indexer or classifier?
Let's consider first that: "Cognitive processes (which may involve language, symbols, or imagery) include perceiving, recognizing, remembering, imagining, conceptualizing, judging, reasoning, and processing information for planning, problem-solving, and other applications" (Gale Encyclopedia of Psychology, 2001); then, in order to comprehend the activities for these 3 different type of jobs, we need to understand that those three are conducted to a similar end: organize one or several collections of information sources in order to be used for a specific type of patron that may look and retrieve it.
In one hand, the cataloger and the classifier usually work for a specific collection, both have to think in which "space" those different sources will be arranged, so, the users know how to locate things easily. In the other hand, an indexer must to think the best way to represent the content in such way there's no way to misplace the source.
The three of them needs to create a learning curve on which they will depend how to apply the decision to asign certain subject or category. Also they need to define the importance on any given subject, depending the community they are serving. For those decision-making process the cognitive process to recognize and judge are essential but in the case of the indexer, they also need to think in the technical implications that are involved to recover the contents when a subject or category is applied. So, the imagination as a cognitive process is involved as well as how to mix conceptualization among different lines of knowledge.
For sources like academic articles it is easier when the autor display the main subject ideas on his /her document. But even in those ocassions, there are many other factors that might influence in the final decision to which subject word is the best when cataloguing or indexing.
I hope  my ideas are well explained. All of the mentioned above are based on my own comprehension on the matter and my experience in the area.

We generally construct hydrogen bond tables seeing the .lis file generated from platon. However,out of all interactions within the crystal, it is necessary to include all of it in the hydrogen bond table? If not, how do we judge which interactions are really appropriate to include? What if two interactions are competing and mutually exclusive? Which do we leave out? Is it really that we should look at the 'survival of the strongest' hydrogen bond all the time?
Relevant answer
Answer
Parameters to be considered when analyzing H bonds are the distances D••••••A and H•••A, and the angle DHA. This angle needs to be of 180º or closer (values upper than 160º are accepted). Distances values depend on the nature of D and A. Publications of Thomas Steiner, about H-bonds, may help.
D = donnor; H = hydrogen; A = acceptor
One may also apply the SHELX instruction HTAB, which automatically analyses hydrogen bonds and generate the H-bond table.

LIS professions are rapidly changing, so there exists a continuous demand for new skills and literacies. What skills, competences and qualifications should LIS students acquire during their studies? What are expectations of students and employers in relation to curriculum and programs, topics and classes, their qualifications and skills acquired?
Relevant answer
Answer
Hi Anna, I agree with Arjun, an ability to understand and use technology is now a prerequisite for a career in Library and Information/Knowledge Services. As a freshly graduated professional you will be in touch with the latest developments in technology, but specific skills like these will fade quickly, so an ability to keep up, keep in touch with developments and maintain overview is also important.
Basic management skills are also important. Project Management, the ability to put together a project proposal with appropriate costings, that kind of thing.
I would also add good communication skills, written and spoken. Can you write a report or plan an effective information skills session. Can you present an idea to a line manager. Could you present a paper to a meeting.
Collaborative working, developing and participating in networks, using social networking for work purposes are important, especially to develop the networks that are going to keep you up to date and engaged with developments in the profession, the further you progress in your career.
An entrepreneurial spirit, the ability to try and think new things is a useful attribute in times of change. In many areas of LIS work today, fortune favours the brave, those who are willing to put themselves forward, apply for funding grants, think of new projects and new approaches to problems.
All this and of course the the core Library and Information Skills are important.
