This study examines how emotional content and characteristics influence the virality and sharing of online content. Specifically:
1) The researchers analyzed almost 7,000 New York Times articles to see which made the "most e-mailed" list, controlling for other factors like prominence.
2) They found positive content is generally more viral than negative. However, arousal level also influences sharing - high-arousal emotions like anger or awe increase virality, while low-arousal emotions like sadness decrease it.
3) Follow-up lab experiments directly manipulated emotions to confirm arousal impacts social transmission. Content that induces more physiological activation is more likely to be shared with others.

Presentation to National Academy of Science workshop on Public Response to Alerts and Warnings Using Social Media. I argued that the citizen science model, in which volunteers contribute to substantive scientific research, is a great model for how to involve the general public in making accurate, actionable social media posts (Twitter, Twitvid, Facebook) that first responders can use to direct their efforts in a disaster.
The Psychology of Sharing
There has been an abundance of research on social media, but to date, no one has asked in a comprehensive way: why do people share? The Psychology of Sharing reveals groundbreaking research that fills this knowledge gap.
This study uncovers:
Primary motivations for sharing
Six sharing personas
Essential steps for marketers aiming to get their content shared
Impact of sharing on Information Management
Cycle of sharing
Enduring role of e-mail in the age of social media

What makes things popular? If you said advertising, think again. People don’t listen to advertisements, they listen to their peers. But why do people talk about certain products and ideas more than others? Why are some stories and rumors more infectious? And what makes online content go viral?
Jonah Berger, author of “Contagious: Why Things Catch On,” shows how to use social influence to spread ideas and create viral traction for your next marketing campaign.
Why are certain pieces of online content (e.g., advertisements, videos, news articles) more viral than others? this article takes a psychological approach to understanding diffusion. Using a unique data set of all the New York Times articles published over a three-month period, the authors examine how emotion shapes virality. the results indicate that positive content is more viral than negative content, but the relationship between emotion and social transmission is more complex than valence alone. Virality is partially driven by physiological arousal. Content that evokes high-arousal positive (awe) or negative (anger or anxiety) emotions is more viral. Content that evokes low-arousal, or deactivating, emotions (e.g., sadness) is less viral. these results hold even when the authors control for how surprising, interesting, or practically useful content is (all of which are positively linked to virality), as well as external drivers of attention (e.g., how prominently content was featured). experimental results further demonstrate the causal impact of specific emotion on transmission and illustrate that it is driven by the level of activation induced. taken together, these findings shed light on why people share content and how to design more effective viral marketing campaigns.

Discuss the concept that attitude and opinion change were considered to be measures of personal. This was because they were assumed to be enduring. Is this assumption still applicable today? Why and how? .(chapter 8)
Attitude is an action toward or away from an attitude object. An opinion is the way people express their attitude or believe. This could be verbalized while attitudes possessed positive and negative drive value. Tow major of research was done by Hovland and Janis address Laswell model of interpersonal communication who says what to whom in what channel with what effect or outcome. In 1953, this was looking for cause and effect and how one elicits change on another.
Hovland, Kelly, and Janis argued attitude and opinion are enduring. They used three steps in order to determine whether attitude change occurred or not. They include attention, comprehension, and acceptance. Not every message that will catch people’s attention. When the message is complicated, it is hard to comprehend and understand. To make the change, individual should accept changes to avoid any regret later. To overcome this regrets we need to work hard to make sure that we carry out the right decisions and which we are comfortable in.
A research on persuasion involves four parts that are communicator, message, audience and response. Credibility goes hand in hand with the communicator's ability to persuade someone. People tend to do dangerous things when in a group than individually. Persuasion is more successful when the individuals are personally convinced r influenced by an absolute choice. Humans are expected to be active in a given task if they are more involved in the persuasion. Someone with an interest in something is more likely to be persuading over time. Using less effort than that who lacks in Personal Influence. The message and credibility are some of the main factors that affect the rate of influencing persons into something.
In the two-step flow of communication, an individual fundamentally influences the other. The media will be more efficient in eliciting change than any other channel. Its influence is indirect rather than direct. Opinion leaders also play a great role in persuading groups of people. It is out of the persuasion that the public makes a choice based on how convinced they are about these choices.
The basic categories which Hovland, Janis, Lumsdaine, and Sheffield addressed in their persusion research are communicator, content, audience and response. It considered central to attitude change. Hovland used Lasswell's formula of "who says what to whom with what effect."
The Communicator (Who) the group studied source credibility, looking at trustworthiness and expertness. They found that, while high-credibility communicators produced better amounts of attitude change, low-credibility communicators produced little attitude change. Another found, when a person with high-credibility gives false information, a person will dissocia.

Nonprofit organizations are increasingly dependent on the involvement of Millennial
constituencies. Three studies investigated their motivations to support charity-linked
events: emotional identification with a cause, self-determination theory (SDT) regula-
tions, and context-related Facebook promotions. This article addresses the recent call to
expand SDT research from a simple analysis of autonomous versus controlled moti-
vation, to studying the effects of all the regulations in the SDT continuum, in particular,
the inclusion of the tripartite dimensions of intrinsic motivation and integrated moti-
vation. Results demonstrated that the greater the emotional identification with the
cause, the stronger was the tendency to support the charity-linked event. Also, the
results in these social media contexts revealed that specific intrinsic dimensions (e.g.,
experience stimulation) are motivators of online and offline support, as is the personal
value nature of integrated regulation. Whereas only autonomous motivational regula-
tions predicted support for the two events organized specifically a for charitable causes,
both autonomous and controlled regulations predicted support of a for-profit event
organized with a charitable cause as an adjunct. These findings can assist practitioners
in designing more effective social media communications in support of charity-linked
events.

Assignment Scenarios
A 2- page analysis of one of the following scenarios. Be sure to include all of the information mentioned in the “Your Task” section of the scenario.
Scenario 1: A European Crisis for Coca Cola
The situation: Review the two articles for Scenario I in this week’s Learning Resources. Imagine that you are an intercultural communication consultant (ICC) entering the Coca Cola Headquarters in Atlanta one month after the first four Belgian children claim they are ill due to consuming Coke products. You are there for another job but are invited into the meeting that is analyzing the handling of this crisis.
To prepare for your Assignment, consider the following:
Imagine that you are an intercultural communication consultant (ICC) entering the Coca Cola Headquarters in Atlanta one month after the first four Belgian children claim they are ill due to consuming Coke products. You are there for another job but are invited into the meeting that is analyzing the handling of this crisis.
• Former Coke CEO Robert Goizueta states, “Business will be the institution of the future. It’s the only global institution” (Greising, 1998, p. 145). Is this accurate? What implications does this have for ICC? • All businesses working across national borders deal with conflicts between corporate culture and the national cultures in which they operate. How would you recommend translating the corporate culture of Coca Cola to the national Belgian culture? • Leaders are symbolic representatives. What recommendations would you have for the CEO, Doug Ivester? • How does the fact that Coca Cola has more revenue per year than the gross domestic product (GDP) of two thirds of all the world’s countries play a role in how they operate in a crisis? • What additional questions would you ask or what additional information would you need in order to give the most effective recommendations?
Your Task: Analyze the countries affected by this product issue. Consider how you would advise the leaders of Coca Cola on how they should have approached the situation from an intercultural communication perspective in order to have minimized the impact on sales and satisfied the needs of the countries affected. Provide recommendations of how Coca Cola could handle similar situations in the future more effectively. Cite at least two of the theories/tools from your Learning Resources to support your recommendations.

The New Boundary Spanners: Social Media Users, Engagement, & Public Relations...Philip Ryan Johnson
Our study investigates the extent to which social media users engaged with organizations online exhibit traditional characteristics of boundary spanners, and whether this engagement results in more positive public relations outcomes for organizations. An online survey was conducted among 403 students and structural equation modeling was used to test a proposed theoretical model. Starbucks and Amazon were selected for this study as both are organizations with a substantial online presence in social media. Results show that social identity and self-efficacy had a positive impact on boundary spanning behaviors, but boundary spanning behaviors did not have a significant impact on social media engagement. However, this study makes an important contribution to current theory in public relations as the results also provide strong empirical evidence for the positive effects that social media engagement has on both relational satisfaction and relational commitment.

Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Notes: The logistic regressions models that appear in this table predict whether an article makes the New York Times’ most emailed list. Successive models
include added control variables, with the exception of Model 6. Model 6 presents our primary regression specification (see Model 4), including only observa-
tions of articles whose content was hand-coded by research assistants. All models include day fixed effects. Models 4–6 include disgust (hand-coded) as a
control because disgust has been linked to transmission in previous research (Heath et al. 2001), and including this control allows for a more conservative test
of our hypotheses. Its effect is never significant, and dropping this control variable does not change any of our results.
