The document discusses computer-assisted instruction (CAI) and its uses in education. It describes how CAI can be used as a tutor to provide individualized instruction to students. While CAI can take over some teaching roles, the teacher still plays an important part in planning lessons, evaluating students, and controlling the learning environment. CAI software typically includes drill and practice, tutorials, games, simulations, discovery activities, and problem solving. The document outlines advantages like interactivity and feedback, but also limitations such as development costs and addressing a limited scope of learning outcomes.

The Family is one of the key institutions of human society.
When man is not at peace with himself this state of affairs is
reflected most in the realm of human relations, particularly in
the family and the relations between the sexes. Any discussion
on the crucial problems of our age and on the future of humanity
is bound to cluster around relations between the sexes and
the institutions of family and education.

Prof. Dr. Muhammad Yunus Zain, S.E., M.A.
As Europe's leading economic powerhouse and the fourth-largest hashtag#economy globally, Germany stands at the forefront of innovation and industrial might. Renowned for its precision engineering and high-tech sectors, Germany's economic structure is heavily supported by a robust service industry, accounting for approximately 68% of its GDP. This economic clout and strategic geopolitical stance position Germany as a focal point in the global cyber threat landscape.
In the face of escalating global tensions, particularly those emanating from geopolitical disputes with nations like hashtag#Russia and hashtag#China, hashtag#Germany has witnessed a significant uptick in targeted cyber operations. Our analysis indicates a marked increase in hashtag#cyberattack sophistication aimed at critical infrastructure and key industrial sectors. These attacks range from ransomware campaigns to hashtag#AdvancedPersistentThreats (hashtag#APTs), threatening national security and business integrity.
🔑 Key findings include:
🔍 Increased frequency and complexity of cyber threats.
🔍 Escalation of state-sponsored and criminally motivated cyber operations.
🔍 Active dark web exchanges of malicious tools and tactics.
Our comprehensive report delves into these challenges, using a blend of open-source and proprietary data collection techniques. By monitoring activity on critical networks and analyzing attack patterns, our team provides a detailed overview of the threats facing German entities.
This report aims to equip stakeholders across public and private sectors with the knowledge to enhance their defensive strategies, reduce exposure to cyber risks, and reinforce Germany's resilience against cyber threats.
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”
Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

The computer as a tutor
1.
2. The computer is one of the wonders of
human ingenuity, even in its original design
in the 1950s to carry out complicated
mathematical and logical operations. With the
invention of the microcomputer (now also
commonly referred to PCs or personal), the
PC has become the tool for programmed
instruction.
3. Educators saw much use of the PC. Its has
become affordable to small business,
industries and homes. They saw its
potential for individualization in learning,
especially as the individualized learning is a
problem since teachers usually, with a class
of forty or more learners. They therefore
devised strategies to use the computer to
break the barriers to individualized
instruction.
6. The computer can be a tutor in effect
relieving the teacher of many activities in
his/her personal role as classroom tutor. It
should be made clear, however, that the
computer cannot totally replace the teacher
since the teacher shall continue to play the
major roles of information, deliver and
learning environment controller. Even the
available computer and CAI software,
7. The teacher must:
Insure that students have the needed
knowledge and skills for any computer
activity.
Decide the appropriate learning objectives.
Plan the sequential and structured activities
to achieve objectives.
Evaluate the students achievements by ways
of tests the specific expected outcomes.
8. On the other hand, the students in CAI play
their own roles as learners as they:
Received information
Understand instruction for the computer
activity
Retain/keep in mind the information and
rules for computer activity
Apply the knowledge and rules during the
process of computer learning.
9. During the computer activity proper in CAI the
computer, too, plays it roles as it:
Acts as sort of tutor ( the role traditional
played by the teacher)
Provides a learning environment
Delivers learning instruction.
Reinforces learning trough drill-and-
practice.
Provides feedback.
10. TYPES OF CAI
1. Drill and Practice
Drill and practice provide opportunities or
students to repeatedly practice the skills that have
previously been presented and that further practice
is necessary for mastery.
2. Tutorial
Tutorial activity includes both the presentation
and information and its extension into different
forms of work, including drill and practice, games
and simulation.
11. 3. Games
Game software often creates a contest to
achieve the highest score and either beat others or
beat others computer
4. Simulation
Simulation software can provide an
approximation of reality that does not require the
expense of real life or its risks.
12. 5. Discovery
Discovery approach provides a large database
of information specific to a course or content area
and challenges the learner to analyze, compare, infer
and evaluate based on their explorations of the data.
6. Problem Solving
This approach help children develop specific
problem solving skills and strategies.
14. ADVANTAGES OF CAI
Interactive
Provides immediate feedback.
Infinitely patient
Motivates learners
Provides consistency in presentation.
Can adjust difficulty to level of
learner.
15. LIMITATIONS OF CAI
Equipment and software can be costly.
Development takes time and money.
Not all learning outcomes are well addressed
by CAI.
Unsophisticated applications may not make
good use of the computer.
Simple CAI has limited modalities (but
multimedia is changing that).
