Analysis of Categorical Data from Historical Perspectives Essays in Honour of Shizuhiko Nishisato
No full textThis book marks a celebration of the career and influence of our dear colleague and
friend, Prof Shizuhiko Nishisato, or “Nishi” as we call him, in honour of his 88th
birthday. Such a milestone deserves a moment to sit back and reflect upon a life
filled with happiness, hope, at times sadness, but with love and passion for all that
drives us forward. So it is with this Festschrift that we all celebrate Nishi’s career
and the influence (both personal and professional) he has had on us all. It is also our
opportunity to thank him for all he has done for us as editors, and for everyone who
was able to contribute to his Festschrift and those who were unable to do so.
Our connection to Nishi dates back about 20 years and so it is relatively young,
certainly in comparison with many of those who have contributed to this book. A key
moment was the first face-to-face meeting of the Nishi/Clavel and Beh/Lombardo
teams at the IFCS (International Federation of Classification Societies) Conference
in Tokyo in 2017. From this meeting came the 2021 Springer book that we had
the pleasure to co-author with Nishi titled Modern Quantification Theory: Joint
Graphical Display, Biplots and Alternatives. So, it came as a pleasant surprise in late
February 2022 that we were invited to edit his Festschrift. Of course, we said “yes”.
We would like to acknowledge the early involvement of Prof. Yasumasa Baba who
is a long-term dear friend of Nishi and who was originally committed to this project
but, unfortunately, was unable to continue in the role.
Nishi’s career spans a great many achievements that are laid out in many of the
papers of this book, and so we leave it to you to peruse the pages and appreciate
the depth of work he has committed a lifetime of passion to. It is safe to say his
impact on quantification theory, and the vast array of research avenues this covers, is
profound. Therefore, this Festschrift is a celebration of many of these avenues and
is divided into four broad topics. The first, “Data Theory” provides a mix of written
and pictorial accounts of Nishi’s life and his work. It also gives some perspective of
Nishi’s influence in the context of the career of Prof. Chikio Hayashi, an early and
highly influential pioneer of quantification theory. The next major part of this book
is titled “On Associations and Scaling Issues” and includes papers that celebrate
Nishi’s impact on the numerical issues concerned with dual scaling and its related
methods, as well as providing new insights into this area of research. A more visual

x Preface
appreciation of the scaling issues is explored in “On Correspondence Analysis and
Related Methods”. Here, the papers discuss a range of issues including the naming
conventions used in the past, exploring the anatomy of correspondence analysis and
detailing extensions of correspondence analysis for analysing various data structures.
The final part of Nishi’s Festschrift is titled “General Topics” and includes papers
that are not necessarily related to issues concerned with quantification theory but
are here because of the close professional and personal connections that Nishi has
shared with the authors over the years.
This celebration of Nishi’s career is a collection of 29 papers where all the
corresponding authors and some of their co-writers were all personally invited to
contribute. We must also acknowledge those who were invited to contribute to this
collection and prepared an early version of their work for inclusion but, ultimately,
were unable to do so. Every one of those who have been invited to contribute to
this collection all share a personal and professional bond with Nishi. These papers
are written by 45 authors that come from all corners of the globe; in alphabetical
order, Australia, Barbados, Canada, England, France, Germany, India, Italy, Japan,
the Netherlands, Scotland, Spain, Switzerland, and the USA.
The preparation of Nishi’s Festschrift would not have been possible without
the help and support of Springer. So, we thank them, and especially Sridevi
Purushothaman, for the many email queries that were patiently responded to. We
also extend our heartfelt appreciation to Pieter Kroonenberg, our close personal
friend and of Nishi’s, for writing the Foreword to this book. Our biggest thanks goes
to each of the authors who have contributed to this collection of celebratory papers.
It has been an immense pleasure communicating with each and every one of you and
the email conversations that have followed. We thank you for your commitment to
this book and for helping to celebrate Nishi as the kind and endearing person that he
is and for the role he has played over the decades as a researcher who has committed
himself to the development of quantification theory and its related methods.
No one succeeds in life without the love of those around them. While we have
all provided various degrees of professional and/or personal help and support over
many years (and decades), his successes rest primarily with his wife Lorraine. So, on
a personal note, we thank Lorraine for her support and love as Nishi has carved a wide
long path through his academic career, a path that many of us have travelled alongside
Nishi or behind him. Whether you subscribe to the phrase of Scott Fitzgerald behind
every great man there is a great woman or Tariq Ramadan’s behind every great man
is not a woman, she is beside him, she is with him, not behind him, or even Jim
Carrey’s behind every great man is a woman rolling her eye, Lorraine’s influence has
been a blessing to us all. So, thank you Lorraine. Finally, we thank Nishi for inviting
us to edit his Festschrift and wish him continued health, happiness and love as he and
those around him continue to mould and direct the next generation of researchers.

Synthetic spectra of BeH, BeD and BeT for emission modeling in JET plasmas
No full textA theoretical model for isotopologues of beryllium monohydride, BeH, BeD and BeT, A to X visible and X to X infrared rovibronic spectra is presented. The MARVEL procedure is used to compute empirical rovibronic energy levels for BeH, BeD and BeT, using experimental transition data for the X , A , and C states. The energy levels from these calculations are then used in the program Duo to produce a potential energy curve for the ground state, X , and to fit an improved potential energy curve for the first excited state, A , including a spin–orbit coupling term, a Λ-doubling state to state (A–X states) coupling term, and Born–Oppenheimer breakdown terms for both curves. These, along with a previously computed ab initio dipole curve for the X and A states are used to generate vibrational-rotational wavefunctions, transition energies and A-values. From the transition energies and Einstein coefficients, accurate assigned synthetic spectra for BeH and its isotopologues are obtained at given rotational and vibrational temperatures. The BeH spectrum is compared with a high resolution hollow-cathode lamp spectrum and the BeD spectrum with high resolution spectra from JET giving effective vibrational and rotational temperatures. Full A–X and X–X line lists are given for BeH, BeD and BeT and provided as supplementary data on the ExoMol website

Reactive collisions between electrons and BeH+ above dissociation threshold
No full textOur previous studies of dissociative recombination, and vibrational
excitation/de-excitation of the BeH ion, based on the multichannel quantum
defect theory, are extended to collision energies above the dissociation
threshold, taking into account the vibrational continua of the BeH ion and,
consequently, its dissociative excitation. We have also significantly increased
the number of dissociative states of , and
symmetry included in our cross section calculations, generating the most
excited-ones by using appropriate scaling laws. Our results are suitable for
modeling the kinetics of BeH+ in edge fusion plasmas for collision energies up
to 12 eV.Comment: 9 pages, 9 figures
Face Detection System / Chan Beh Teng
No full textThe aim of this project is to replicate on a computer what humans beings are able to do so effortlessly - detect the presence of the faces in their field of vision. To a layman, it may appear trivial, but to actually implement the necessary steps leading to successful execution of this in n algorithm is difficult and still an unsolved problem in computer vision.The proposed Face Detection System is an application that automates the detection of frontal human faces(s) in a given image. The System perform all tasks including image pre-processing, analysis and output. The user merely present it with the image. The system takes as input a 24 bit RGB colour image which containts face(s). Before the detection process begins, the system pre-processes the image into a format required by the system. The system will generate an output where every detected face will be indicated with a rectangle on a copy of the original image. The method used for detecting face is a combination of color based technique and template matching. A gray-scale image is generated from the original input image. Skin regions are then separated from skin regions by segmenting the gray-scale image. After that, the system will locate the frontal human face(s) within the skin regions, using template matching. The Face Detection System is implemented in visual Basic 6.0 The system was developed based on the Unified Process,which uses object-oriented paradigm as the basis of software development
Synthetic spectra of BeH, BeD and BeT for emission modeling in JET plasmas
No full textA theoretical model for isotopologues of beryllium monohydride, BeH, BeD and BeT, A 2P to X 2Σ+ visible and X 2Σ+ to X 2Σ+ infrared rovibronic spectra is presented. The MARVEL procedure is used to compute empirical rovibronic energy levels for BeH, BeD and BeT, using experimental transition data for the X 2Σ+, A 2P, and C 2Σ+ states. The energy levels from these calculations are then used in the program Duo to produce a potential energy curve for the ground state, X 2S, and to fit an improved potential energy curve for the first excited state, A 2P, including a spin-orbit coupling term, a λ-doubling state to state (A-X states) coupling term, and Born-Oppenheimer breakdown terms for both curves. These, along with a previously computed ab initio dipole curve for the X and A states are used to generate vibrational-rotational wavefunctions, transition energies and A-values. From the transition energies and Einstein coefficients, accurate assigned synthetic spectra for BeH and its isotopologues are obtained at given rotational and vibrational temperatures. The BeH spectrum is compared with a high resolution hollow-cathode lamp spectrum and the BeD spectrum with high resolution spectra from JET giving effective vibrational and rotational temperatures.

Genetic and genomic analyses of musculoskeletal differences between BEH and BEL strains
No full textBerlin high (BEH) and Berlin low (BEL) strains selected for divergent growth differ 3-fold in body weight. We aimed at examining muscle mass, which is a major contributor to body weight, by exploring anatomical characteristics of the soleus muscle, its fiber numbers and their cross sectional area (CSA), by analysing transcriptome of the gastrocnemius and by initiating quantitative trait locus (QTL) mapping. BEH muscles were 4-to-8 times larger compared to BEL strain. In sub-strain BEH+/+, mutant myostatin was replaced with a wild type allele, however, BEH+/+muscles still were 2-to-4 times larger compared to the BEL strain. BEH soleus contained 2-times more (P<0.0001) and 2-times larger in CSA (P<0.0001) fibers compared to BEL strain. In addition, soleus femoral attachment anomaly (SFAA) was observed in all BEL mice. One significant (chromosome 1) and four suggestive (chromosomes 3, 4, 6 and 9) muscle weight QTLs were mapped in 21-day old F2 intercross (n=296) between BEH and BEL strains. The frequency of SFAA incidence in the F2 and in the backcross to BEL strain (BCL) suggested the presence of more than one causative gene. Two suggestive SFAA QTLs were mapped in BCL, however, their peak markers were not associated with the phenotype in F2. RNA-Seq analysis revealed 2,148 differentially expressed (P<0.1) genes and 45,673 SNPs and >2,000 indels between BEH+/+ and BEL males. In conclusion, contrasting muscle traits, genomic and gene expression differences between BEH and BEL strains provide a promising model for the search of genes involved in muscle growth and musculoskeletal morphogenesis
Motion under gravity: a creative lesson from the paradigm of constructivism / Beh Kian Lim.
No full textThis paper offers insight into the author’s experience of teaching the topic of motion under gravity to students enrolled in a pre-service science teacher preparation program. The instructional method is based on the activity of the alternative to Galileo’s experiment using the three stage teaching sequences proposed by Nussbaum and Novick from the paradigm of constructivism. The activity reveals the general misconception among pre-service physics teachers and non-physics majors regarding motion
under gravity. The paper also highlights the research findings of two studies based on the same classroom activity - the alternative to Galileo’s experiment. The studies involve two groups of Form Four secondary school students from urban and rural settings. The empirical data derived from the study of school students is consistent with the observation data gathered from the pre-service science classroom activity. It is concluded that the usual way of teaching the topic of motion under gravity with the
goal of introducing the idea of gravitational acceleration is ineffective To rectify this shortcoming, the author suggests the ‘teach less-learn more’ philosophy that is in line with suggestions made in most recent science education reform documents. It is suggested that insights from this study can contribute to improvements in the training of future science teachers
Pricing of American call options using simulation and numerical analysis / Beh Woan Lin
No full textConsider the American basket call option in the case where there are N underlying
assets, the number of possible exercise times prior to maturity is finite, and the vector of
asset prices is modeled using a Levy process. A numerical method based on regression
and numerical integration is proposed to estimate the prices of the American options. In
the proposed method, we make use of the distribution for the vector of asset prices at a
given time t in the future to determine the “important” values of the vector of asset
prices of which the option values should be determined. In determining the option
values at time t, we first perform a numerical integration along the radial direction in the
N-dimensional polar coordinate system. The value thus obtained is expressed via a
regression procedure as a function of the polar angles, and another numerical
integration is performed over the polar angles to obtain the continuation value. The
larger value of the continuation value and the immediate exercise value will then be the
option value. A method is also proposed to estimate the standard error of the computed
American option price
