Designing digital comprehensive system to test and assess the intelligently b...ijfcstjournal
Intelligence Quotient (IQ) is a ratio achieved by dividing the mental age over chronological age. There are
several ways to achieve a mental age and usually professionals use certain tests. In order to avoid having
decimals and facilitate calculations, the result of mental age/chronological age ration is multiplied by 100.
IQ tests are used to determine IQ value. Tests and methods available to determine IQ have shortcomings
such as time-consuming nature of the tests, non-comprehensive tests, non-systematic tests, etc. This article
seeks to design a comprehensive digital system for testing and evaluating children's IQ according to
Wechsler's Intelligence Theory to solve problems of the tests and methods available.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Question;
Intelligence Quotient (IQ) test
2. Intelligence is the ability to solve problems and to adapt to and learn from life’s everyday
experiences (i.e. Includes characteristics such as creativity and interpersonal skills; The mental
abilities that enable one to adapt to, shape, or select one’s environment; The ability to judge,
comprehend, and reason; The ability to understand and deal with people, objects, and symbols;
The ability to act purposefully, think rationally, and deal effectively with the environment).
Howard Gardner suggested eight types of Multiple Intelligences and He believed each of us
have all of the eight types of intelligence to varying degrees. These are related to how an
individual prefers to learn and process information. They include;
1. Verbal skills: The ability to think in words and use language to express meaning.
Sensitivity to the meanings and sounds of words, mastery of syntax, appreciation of the
ways language can be used (authors, journalists, speakers, poets, and teachers)
2. Mathematical skills: The ability to carry out mathematical operations. Understanding of
objects and symbols and of actions that be performed on them and of the relations
between these actions, ability for abstraction, ability to identify problems and seek
explanations (scientists, engineers, accountants)
3. Spatial skills: The ability to think three-dimensionally. Capacity to perceive the visual
world accurately, to perform transformations upon perceptions and to re-create aspects of
visual experience in the absence of physical stimuli, sensitivity to tension, balance, and
composition, ability to detect similar patterns (architects, artists, sailors, chess masters)
4. Bodily-kinesthetic skills: The ability to manipulate objects and be physically adept. Use
of one’s body in highly skilled ways for expressive or goal-directed purposes, capacity to
handle objects skillfully (surgeons, craftspeople, dancers, athletes, actors)
5. Musical skills: sensitivity to pitch, melody, rhythm, and tone. Sensitivity to individual
tones and phrases of music, an understanding of ways to combine tones and phrases into
larger musical rhythms and structures, awareness of emotional aspects of music
(musicians, composers, sensitive listeners)
6. Interpersonal skills: The ability to understand and effectively interact with others.
Ability to notice and make distinctions among the moods, temperaments, motivations,
and intentions of other people and potentially to act on this knowledge (teachers, mental
health professionals, parents, religious and political leaders)
3. 7. Intrapersonal skills: The ability to understand oneself. Access to one’s own feelings,
ability to draw on one’s emotions to guide and understand one’s behavior, recognition of
personal strengths and weaknesses (theologians, novelists, psychologists, therapists)
8. Naturalistic skills: The ability to observe patterns in nature and understand natural and
human -made systems. Sensitivity and understanding of plants, animals, and other aspects
of nature (farmers, botanists, ecologists, landscapers, environmentalists)
Factors Influencing Intelligence
1. The Child’s Influence:
• Genetics
• Genotype–Environment Interaction
• Gender (Boys and girls tend to be equivalent in most aspects of intelligence; The
average IQ scores of boys and girls is virtually identical; The extremes (both low
and high ends) are over- represented by boys)
Girls as a group: Tend to be stronger in verbal fluency, in writing, in perceptual speed (starting
as early as the toddler years). Boys as a group: Tend to be stronger in visual-spatial processing,
in science, and in mathematical problem solving (starting as early as age 3)
2. The Immediate Environment’s Influence
• Family Environment
• School Environment
3. The Society’s Influence
• Poverty (The more years children spend in poverty, the lower their IQs tend to be;
Reduced access to health service, poor parenting, and insufficient stimulation and
emotional support can impair intellectual growth)
• Race/Ethnicity (Overall, differences in IQ scores of children from different racial
and ethnic groups describe children’s performance ONLY in the environments in
which the children live. These findings do not indicate potential, nor do they tell
us what these children would do if they live someplace else. The current group
differences in IQ are due to environmental differences -- as discrimination and
inequality decrease -- IQ differences decrease).
4. Hence, as we think about what intelligence is, we should ask the following questions:
To what extent is intelligence genetic?
To what extent is intelligence stable?
How do cognitive abilities interact with other aspects of functioning?
Are there true sex differences?
Is intelligence a global capacity (similar to “good health”) or can it be differentiated into
various dimensions (called “factors” or “aptitudes”)?
Are there a number of “intelligences”?
How do you measure intelligence?
The above questions lead to the main question: How do you measure intelligence?
Intelligence Quotient (IQ): Measure of intelligence that takes into account an individual’s/
child’s mental and chronological age. In otherworld’s IQ is a total score derived from
several standardized tests designed to assess human intelligence.
IQ Score = MA / CA x 100
Mental age (MA): the typical intelligence level found for people at a given chronological age
Chronological age (CA): the actual age of the individual/child taking the intelligence test
People whose mental age is equal to their chronological age will always have an IQ of 100. If the
Chronological age exceeds mental age – below-average intelligence (below 100). If the mental
Age exceed the chronological age – above-average intelligence (above 100).
Most common Types of IQ Tests
Since Goddard’s controversial Binet tests, psychologists have worked to develop numerous other
tests. Most are intended for elementary school-aged children, but some may be used for adults.
The most common types of IQ tests are:
5. 1. Stanford-Binet Intelligence Scale (BS5) It is a cognitive ability and intelligence test that
is used to diagnose developmental or intellectual deficiencies in young children. The
Stanford–Binet Intelligence Scale is now in its fifth edition (SB5) and was released in
2003. the Stanford–Binet is a modified version of the Binet-Simon Intelligence scale. The
Binet-Simon scale was created by the French psychologist Alfred Binet and his
student Simon. Binet believed that intelligence is malleable and that intelligence tests
would help target kids in need of extra attention to advance their intelligence.
2. The Wechsler Intelligence Scales the intelligence scales developed by David Wechsler
include several successive editions of three scales; one designed for adults i.e. Wechsler
Adult Intelligence Scale (WAIS) appropriate for use with individuals aged 16–90 years,
one for school aged children i.e. Wechsler Intelligence Scale for Children (WISC, 6–16
years), and one for Preschool and Primary children i.e. Wechsler Preschool and Primary
Scale of Intelligence (WPPSI, 2½–7 years, 7 months) are used.
Wechsler Adult Intelligence Scale (WAIS) is an IQ test in adults and older
adolescents designed to measure intelligence and cognitive ability. It is currently in its
fourth edition (WAIS-IV) released in 2008 by Pearson, and is the most widely used IQ
test, for both adults and older adolescents, in the world. Data collection for the next
version (WAIS 5) began in 2016 and is projected to be complete in 2019 The WAIS-IV
measure is appropriate for use with individuals aged 16–90 years.
Wechsler Intelligence Scale for Children (WISC) has 2 scales (verbal an performance)
with 10 items.
Wechsler Preschool and Primary Scale of Intelligence (WPPSI) has 2 scales (verbal an
performance with also 10 items but different from the ones in the WISC.
3. Kaufman assessment battery for children (K-ABC) which was developed from
Stanford-Binet and Wechsler Scales. It measures ability in reading, arithmetic, word
knowledge and general recognition
6. Administration of the IQ tests
1. Stanford-Binet Intelligence Scale The test measures five weighted factors and consists
of both verbal and nonverbal subtests. The five factors being tested are;
Knowledge
Quantitative reasoning
Visual-spatial processing
Working memory
Fluid reasoning.
The SB5 can be administered to individuals as early as two years of age. There are ten
subsets included in this revision including both verbal and nonverbal domains. For every
verbal subtest that is used, there is a nonverbal counterpart across all factors. These
nonverbal tasks consist of making movement responses such as pointing or assembling
manipulative.
These counterparts have been included to address language-reduced assessments in
multicultural societies. Depending on age and ability, administration can range from
fifteen minutes to an hour and fifteen minutes.
The fifth edition incorporated a new scoring system, which can provide a wide range of
information such as four intelligence score composites, five factor indices, and ten subtest
scores. Additional scoring information includes percentile ranks, age equivalents, and a
change-sensitive score Extended IQ scores and gifted composite scores are available
with the SB5 in order to optimize the assessment for gifted programs
To reduce errors and increase diagnostic precision, scores are obtained electronically
through the use of computers now.

2. Wechsler Adult Intelligence Scale (WAIS) The current version of the test, the WAIS-
IV, which was released in 2008, is composed of 10 core subtests and five supplemental
subtests, with the 10 core subtests comprising the Full Scale IQ. With the new WAIS-IV,
the verbal/performance subscales from previous versions were removed and replaced by
the index scores and the General Ability Index. GAI is clinically useful because it can be
used as a measure of cognitive abilities that are less vulnerable to impairments of
processing and working memory.
There are four index scores representing major components of intelligence:
Verbal Comprehension Index (VCI)
Perceptual Reasoning Index (PRI)
Working Memory Index (WMI)
Processing Speed Index (PSI)
Two broad scores, which can be used to summarize general intellectual abilities, can also be
derived:
8. Full Scale IQ (FSIQ), based on the total combined performance of the VCI, PRI, WMI, and
PSI
General Ability Index (GAI), based only on the six subtests that the VCI and PRI comprise.

Interpretation of an IQ Test Results
According to the National Institute of Child Health and Human Development, 85 percent of
intellectually disabled children receive IQ scores between 55 and 70. A score of 100 is
considered average.
The normal distribution: most of the population falls in the middle range of scores between 84
and 116.
• Very Superior Intelligence (gifted) - Above 130
• Superior Intelligence - 120 to 129
• High Average Intelligence - 110 to 119
• Average Intelligence - 90 to 109
• Low Average Intelligence - 80 to 89
• Borderline Intellectual Functioning - 71 to 79
• Mild Mental Retardation - 55 to 70
• Moderate Retardation - 40 to 54
• Severe Mental Retardation - 25 to 39
• Profound Mental Retardation - Below 25
11. IQ testusage
IQ tests are used for different purposes and problems such as;
Choice of profession and associated problems
Staff selection
Choice of school and study
Clinical research into illnesses that negatively affect intelligence, such as dementia.
IQ testing is used in courts to determine whether a defendant has special or extenuating
circumstances that preclude him from participating in some way in a trial.
People also use IQ testing results to seek disability benefits from the Social Security
Administration.
