This study analyzed video footage of police interviews with 16 criminal suspects to determine behavioral indicators that distinguish lying from truth telling. The researchers coded behaviors like gaze aversion, blinking, hand movements, and pauses. Results found most participants paused longer and blinked less while lying, but there were no universal deception behaviors. Individual differences occurred. The findings provide some support for the idea that lying places higher cognitive load but did not directly measure or manipulate cognitive load. The study challenges the notion that typical deception behaviors exist and highlights the need for a behavioral baseline.
Grit is not hard work. It is single-mindedness. Research indicates that if a candidate answers 'I finish whatever I begin' then he is most probably our candidate for performance. Or is it?
Brand As Verb: Principles of High Performing Experience BrandsBen Grossman
80% of leaders say their brands offer a superior customer experience. Only 8% of customers agree. Meanwhile, marketers are tortured by the fact that the number one way people learn about and buy from their brands is the hardest one to control: word-of-mouth. In today’s world of new realities it doesn’t pay for brands to stand by, continuing to trumpet their “creative messaging.” After all, 74% of people advocate for brands by describing their experiences with them. Brands that break through are brands that take action… brands that are more than nouns. Brands must see themselves as verbs.

This lecture slide concerns the accuracy report of eye witness testimony. How accurate are eye-witness testimonials? And how can we interview witness so that their reports can be more accurate? It identifies the 'Cognitive Interview Model' which is a interview approach for increasing accuracy of reports while minimizes false information. One of the main mistake of interviewers are asking misleading questions. For instance, 'did you see the gun?' as opposed to 'did you see 'a' gun?' First part was misleading because it implies that a gun was witnessed when in fact there may not have been a gun present.

A summary of the project is as follows: Anthropogenic stressors are affecting thermosensitive engineering species like the white gorgonians (Eunicella singularis), causing mass mortality events in the northwest Mediterranean Sea. Assessment of population structure through the use of genetic markers is often conducted, but little is known about the intricacies of subjective allele scoring and sampling effort. Eight datasets were prepared to explore the effect of expertise and subjectivity on allele scoring, and the effect of markers and sampling effort. Each dataset was analysed to obtain a consistent set of genetic diversity metrics and cluster patterns. Relevant datasets were compared to identify significant differences. Our results suggest that a detailed and adaptive allele scoring criteria, along with quality control measures were necessary for reproducible results. Informative markers and sampling sites were crucial for the best interpretation of the population structure. These findings suggest that scaling down of the resources used in population genetic studies are possible and further studies could be established to confirm and correlate this to E. singularis genome size and the potential outcomes when other markers such as single nucleotide polymorphisms (SNPs) are used.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

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!

2. SUSPECT, LIES AND VIDEO TAPES: AN
ANALYSIS OF AUTHENTIC HIGH-STAKE
LIARS
-Samantha Mann, Aldert Vrij and Ray Bull
3. Background
This study is one of the very few, and the most
extensive to date, which has examined
deceptive behavior in a real-life, high-stakes
setting. The behavior of 16 suspects in their
police interviews has been analyzed. Clips of
video footage have been selected where other
sources (reliable witness statements and
forensic evidence) provide evidence that the
suspect lied or told the truth.
4. Aim
• To determine if there are systematic
behavioral indicators to distinguish between
those who are telling lies and those who are
telling the truth.
• To determine if cognitive load (complex
cognitive processes) causes changes in
behavior relevant to lying or telling the truth
5. •Real life high
• Deceptive stake lies
behaviour •Cognitive
• Veracity Load
•Blind testers
7. SAMPLE
•4 participants were juveniles :3 aged 13 and other aged 15
• Remainder were adult < 65 years
•15 were Caucasian (where English was their first
language)
•1 participant was of Asian ethnicity (a male whose first
language was Punjabi but who was fluent in English).
• All interviews were conducted in English.
13 3
8. SAMPLE
•Range of crimes:
1. theft (N =9)
2. arson (N =2)
3. attempted rape (N =1)
4. murder (N =4).
•The majority of participants (at least 10 of
16) were well known to the police and had
been interviewed on several occasions
previously, relating to previously committed
offenses.
9. PROCEDURE
• Police detectives at Kent County Constabulary, UK, were asked if
they could recollect videotaped interviews in which they were
involved where the suspect had lied at one point and told the
truth at another.
• The end result was an hour-long videotape consisting of clips from
16 suspects. Truths that were selected were chosen so as to be as
comparable as possible in nature to the lies (a truthful response to
an easy question such as giving a name and address was not
comparable to a deceitful response regarding whether or not the
suspect has committed a murder. Video-footage about names
and addresses were therefore not included as truths in this study).
• Total of 65 video clips (27 truth / 38 lies)
• Length of clip and length of response varied but not significant in
terms of analysis of behavior.
• Two observers independently coded behavior and were
compared for inter-rater reliability on a sample of the videos (not
all of them)
10. • Behaviours recorded were: 1) gaze aversion, 2) blinking, 3)
head movements, 4) self-manipulations, 5) illustrators, 6)
Hand-finger movements, 7) speech disturbances 8)pauses
• Given the small number of participants and relative large
number of behaviors, researchers reduced behavioral
indices by clustering the three types of hand and arm
movements (illustrators, self manipulations, and
hand/finger movements) into one category “hand and
arm movements.” This clustering had no effect on the
results.
• Each of the coded behaviors was transformed into a
format in order that truths and lies may be directly
compared.
For example: Hand & Arm Movements X 60
Total length of truth/lying
11. RESULTS
• Data was analyzed using Multivariate
Analysis of Variance (MANOVA): a statistical
test procedure for comparing multivariate
(population) means of several groups.
• Veracity was the only within subject factor
and the dependent variables were the six
listed in the table.
13. EVALUATION OF RESULTS
Individual differences occurred and there was no
particular behaviour that all liars exhibited.
50% showed an increase and 50% showed a decrease in
head movements and speech disturbances while lying.
56% 44% - gaze aversion
More participants (69%) showed an than in hand
movements during deception.
Blinking and pausing as the majority of participant
paused longer and blinked less while lying (81%)
14. DISCUSSION
• The findings of the study give some support for the
cognitive load process in explaining deceptive
behaviour.
• Falsifies the stereotypical view of increased
blinking; Nixon effect
• However, neither cognitive load nor nervousness
were measured or manipulated before the study
conclusions were speculative
15. APPLICATIONS
Challenges the simplistic views of
professional lie catchers that a typical of
deceptive behaviours exists.
Highlights the importance of establishing a
baseline behaviour before attempting to
detect deception.
16. STRENGTHS
• Control of variables in lab experiment;
• inter-rater reliability;
• specific behaviors identified and measured;
• quantitative data- reliable
17. Different interviewers were used for different participants.
Sometimes more than one interviewer was present.
The total number of people present varied.
Though these factors may have influenced the person’s
behaviour, the researchers controlled these factors using within
factor design.
No comparison between high stake liars and high stake truth
tellers.
Small sample size= not generalizable (this was because of the
limited availability of appropriate tapes and the time
consuming process of obtaining them) limits generalizability to
criminals in police custody only.
People who have been arrested more than once might
experience less fear and guilt, be more experienced liars.
