Social Impacts of Cyber Crime
Cyber criminals take advantage of the fast paced advancement of technology and the individuals who are unsophisticated and have no idea where the Internet fits into their world.
Thieves have become very skilled in using the anonymity of the Internet to trick victims into giving them what they want.
“The scammer tries to prey on victims who are kind of in tune with what’s going on in the world. The scam changes, but ultimately they’re preying on the good will of people” (Donnelly, 2011).
No matter what aspect of cyber crime that happens to an individual, or if restitution was made, the effects of cyber crime can be devastating.
Cyber crime: concepts methodologies, tools, and applications
Types of Cyber Crime
Cyber –Tresspass ( Viruses, Denial of Service attacks)
Cyber –deceptions (identity theft, fraud, piracy)
Cyber-pornography
Cyber-violence (cyberbullying, cyber stalking)

1. Identify one (1) evidentiary issue that could be presented regarding the admission of digital evidence at trial. Next, suggest one (1) way in which the court could take to resolve the issue that you have identified. Include one (1) example of such issue and your suggestion action to support your response.
Per the text, there is probable cause to search a computer or electronic media when one believes that the computer or related media either contains or is contraband evidence of a crime, fruits of crime, or instrumentality of a crime. Identify at least two (2) types of warrantless searches that investigators can conduct while collecting digital evidence, and explain the main reasons why you believe the types of searches in question are warrantless. Justify your response.
PLEASE KEEP COMPLETELY SEPARATE FROM 1 AND THIS IS A RESPONSE TO THE POST BELOW 50 to 75 words
2.
One evidentiary issue that could be presented regarding the admission of digital evidence at trial is if the evidence is clear and convincing. For example, When looking channel 7; when someone is maybe breaking into someone's house or breaking into a store. I have seen video feed thats just a shadow, or maybe the person has on something that hides their face. They willstill ask if you reconize that person. Unfortunately, it's hard to figure out who the suspect is because the image maybe bad or they may becovered. There is no way to solve this issue unless they have some kind of tattoo or scar that could be pointed out.
Two types of warrentless searches are: Plain-view search and Exigent circumstances. Plain-view search, a warrent isn't required for this because; if your investigating someone and you see criminal activity on their computersc, no matter what it is; you can use that informaton because as long it can be seen by the general public. Exigent circumstances, a warrent isn't required for this because; it may an immediate emergency. For example, a murder, kidnap, robbery or anyother type of crime.

Because the Office suite programs have a similar interface (look and feel), it is easy to learn the program tools. Office documents are compatible (easy to incorporate or integrate) with one another.
The first step in using an Office program is to open or launch it on the computer. The easiest way to launch a program is to click the Start button on the Windows taskbar or double-click an icon on the desktop. A user interface is a collective term for all the ways you interact with a software program. A file is a stored collection of data. Saving a file enables you to work on a project now and then put it away and work on it again later. Printing can be a simple or complex task. It helps to preview a document to see exactly what a document will look like when it is printed. Each Microsoft

Social Impacts of Cyber Crime
Cyber criminals take advantage of the fast paced advancement of technology and the individuals who are unsophisticated and have no idea where the Internet fits into their world.
Thieves have become very skilled in using the anonymity of the Internet to trick victims into giving them what they want.
“The scammer tries to prey on victims who are kind of in tune with what’s going on in the world. The scam changes, but ultimately they’re preying on the good will of people” (Donnelly, 2011).
No matter what aspect of cyber crime that happens to an individual, or if restitution was made, the effects of cyber crime can be devastating.
Cyber crime: concepts methodologies, tools, and applications
Types of Cyber Crime
Cyber –Tresspass ( Viruses, Denial of Service attacks)
Cyber –deceptions (identity theft, fraud, piracy)

Next, suggest one (1) way in which the court could take to resolve the issue that you have identified. Include one (1) example of such issue and your suggestion action to support your response.
Per the text, there is probable cause to search a computer or electronic media when one believes that the computer or related media either contains or is contraband evidence of a crime, fruits of crime, or instrumentality of a crime. Identify at least two (2) types of warrantless searches that investigators can conduct while collecting digital evidence, and explain the main reasons why you believe the types of searches in question are warrantless. Justify your response.
PLEASE KEEP COMPLETELY SEPARATE FROM 1 AND THIS IS A RESPONSE TO THE POST BELOW 50 to 75 words
2.
One evidentiary issue that could be presented regarding the admission of digital evidence at trial is if the evidence is clear and convincing. For example, When looking channel 7; when someone is maybe breaking into someone's house or breaking into a store. I have seen video feed thats just a shadow, or maybe the person has on something that hides their face. They willstill ask if you reconize that person. Unfortunately, it's hard to figure out who the suspect is because the image maybe bad or they may becovered. There is no way to solve this issue unless they have some kind of tattoo or scar that could be pointed out.
Two types of warrentless searches are: Plain-view search and Exigent circumstances. Plain-view search, a warrent isn't required for this because; if your investigating someone and you see criminal activity on their computersc, no matter what it is; you can use that informaton because as long it can be seen by the general public. Exigent circumstances, a warrent isn't required for this because; it may an immediate emergency. For example, a murder, kidnap, robbery or anyother type of crime.

Two popular programs being assessed for this purpose are “Family Planning” (FP) and “Health-Drive-Screenings” (HDS); their costs to the hospital for each offering are $200 and $400, respectively. The health care manager in charge of operations found three common patterns of resource consumption for each of these services and the available resources, shown in Table EX 10.2.

10 Things to Know About the Psychology of Cults
Both terrifying and utterly fascinating, cults have a tendency to capture the attention of just about everyone. Questions abound: Where do these people come from? What are they really doing inside those secluded compounds? Most interesting, perhaps, are the psychological components of cult life, questions such as: Who in the world would fall for that? In an effort to answer these questions and more, we’ve listed 10 things to know about the psychology of cults.
Cults are attractive because they promote an illusion of comfort.
Humans desire comfort, and in a fearful and uncertain world many turn to cults because they tend to promote exactly that. Jon-Patrik Pedersen, a psychologist at CalTech, has pointed out that cult leaders often make promises that are totally unattainable, but also offered by no other group in society. Such things might include financial security, total health, constant peace of mind, and eternal life — the things every human desires at the deepest level.
Cults satisfy the human desire for absolute answers.
Today’s world is a tough one, with more abstract issues than there are issues that are black and white. As Dr. Adrian Furnham describes in
Psychology Today
, humans crave clarity. Many people join cults because they believe they’re being offered solid, absolute answers for questions such as good vs. evil, religion, the meaning of life, politics, etc. Many cult leaders promote messages that are simple and seem to make sense, the exact opposite of what we’re often provided with in typical, everyday life.
Those with low self-esteem are more likely to be persuaded by a cult environment.
People are often surprised to learn that those who join cults are, for the most part, average people. They come from all backgrounds, all zip codes, and all tax brackets. But research done in the past two decades has found an interesting pattern: many people successfully recruited by cults are said to have low self-esteem. Cults generally do not look to recruit those with certain handicaps or clinical depression. However, people with low self-esteem are easier to break down, then build back up in an effort to teach them that the cult is the supportive environment they’re looking for.
New recruits are “love bombed.”
Once people have been recruited by a cult, they are often “love bombed.” This odd phrase is commonly used to describe the ways in which someone with low self-esteem is consistently flattered, complimented, and seduced in order to train their brain to associate the cult with love and acceptance.
Women are more likely than men to join a cult.
According to various research, women make up a whopping 70% of cult members around the globe. Psychologists have different ideas about why more women than men join cults. Dr. David Bromley of Virginia Commonwealth University points out that women simply attend more social gatherings, either religious or otherwise. This makes wom.

The “anchor standards” in the
Common Core State Standards
define college and career read-
iness, in part, as the ability to
“integrate and evaluate content
presented in diverse media and
formats, including visually and
quantitatively, as well as in words.”
www.corestandards.org
Meet the Standards
The NETS for Students address skill sets that include the
interpretation and creation of infographics. The NETS’
Creativity and Innovation indicators include creating
original works and using models, its Communication
and Collaboration indicators speak to communicating
information and ideas using a variety of media, and
the Research and Information Fluency section refers to
processing data and reporting results using a variety of tools.
iste.org/standards/nets-students
Most subject-matter
standards give attention
to sense-making and
information literacy,
both of which students
develop when they
interpret and design
infographics.
By Jane Krauss
More Than Words Can Say
Good learning experiences
ask students to investigate
and make sense of the
world. While there are
many ways to do this, K–12
curriculum has traditionally
skewed toward reading
and writing to interpret
and express students’
sense-making. But there
is another way. Infographics
represent data and ideas
visually, in pictures, engag-
ing more parts of the brain
to look at a problem from
more than one angle.
Infographics ask for an
active response from the
viewer, raising the ques-
tions, “What am I seeing?”
and “What does it mean?”
As the old adage goes,
a picture is worth 1,000
words, and pictures can be
essential when complexity
demands more than words
can say.

What Is an
Infographic?
Simply put, infographics
are visual displays
of information.
An
infographic
is handcrafted to
bundle related data sets
into a unified, visually
compelling representation.
The juxtaposition of those
sets of information relates
a more complex
story.
Infographics go
a step beyond the old-
fashioned graphics—charts,
timelines, tables, and graphs—
created by simply applying a
computer program to a few
like data sets.

Boost Comprehension
Much of the mental processing that goes
into the development of infographics has
parallels in computational thinking (CT), the
thinking patterns that computer scientists
use to solve problems. CT skills have value
beyond computer science, as they help us
approach problems and apply processes to
solve them. CT can help students practice
with data sets of any size, manipulate that
data, and represent it in an infogr.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
