The Lighting industry has been through a revolution in the last few years with LED technology taking over from HID lamp sources and although better understood now than they were five years ago, we have seen a general uncertainty arise around a number of topics. In a reaction to this lack of understanding we now witness, as a suggested part of tender submissions, questions being asked that were never asked of HID solutions, these were posed when LED street lighting technology was developing. For example, whether the colour shift was 3, 4 or 5 macadam ellipses was perhaps pertinent a few years ago in relation to how the LEDs would perform, yet the industry was never to bothered when Son lamps changed their colour appearance and colour rendering properties within their relatively short life. With the maturing LED technology are they really still appropriate to be asked and what should the buyer really be asking instead?
This talk will look to explore these areas and clarify in simple terms the reality. Topics covered will include maintenance factors, the use of constant light output, control of glare and explore the use of drivers in the lanterns – basically the weakest link.
It will finally look at areas of research required to further our confidence in using the new technology and the wider lighting research being carried out by the CIE.
Talk by Nigel Parry IEng FILP MSLL, OrangeTek
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
Leaders are often faced with ethical conundrums(a confusing and difficult problem or question). So how can they determine when they’re inching toward dangerous territory? There are three main psychological dynamics that lead to crossing moral lines.
There’s omnipotence: when someone feels so aggrandized and entitled that they believe the rules of decent behavior don’t apply to them.
Consider cultural numbness: when others play along and gradually begin to accept and embody deviant norms.
Finally, when people don’t speak up because they are thinking of more immediate rewards, we see justified neglect.
Generally most people mean well, but simply execute their job poorly sometimes and sometimes, there are BAD bosses. We must learn “to Work "on Bad Boss
According to dictionary.com, “to work” something or someone is to put them into effective operation, to operate that thing or person for productive purposes.
Put your Bad Boss into effective operation to get whatever you want in your job or career by learning your boss’s secret desire and secret fear
Two biggest issues of Bad Boss are:
They can negatively impact our work performance.
They can make life miserable
We often hear “being difficult.” about Bad Boss. It’s hard to know exactly where the difficulty lie. All we know is it is difficult to work successfully with this person.
An incompetent person is someone who is
Functionally inadequate or
Insufficient in Knowledge, Skills, Judgment, or Strength
Mindset is a mental attitude that determines how we interpret and respond to situations.
Dweck has found that it is your mindset that plays a significant role in determining achievement and success.
A mindset refers to whether you believe qualities such as intelligence and talent are fixed or changeable traits.
People with a fixed mindset believe that these qualities are inborn, fixed, and unchangeable.
Those with a growth mindset, on the other hand, believe that these abilities can be developed and strengthened by way of commitment and hard work.
Story of Katalin Karikó, a researcher who won the Nobel prize for medicine for her work on modifying the RNA molecule to avoid triggering a harmful immune response is a classical example of mindset.
Yet, her life was full of rejection and doubt.
Her achievement had much to do with her mindset.
A theory is a based upon a hypothesis and backed by evidence.
A theory presents a concept or idea that is testable.
In science, a theory is not merely a guess.
A theory is a fact-based framework for describing a phenomenon.
In psychology, theories are used to provide a model for understanding human thoughts, emotions, and behaviors.
Hence study of Psychology theory is essential for SSB and all types of Interviewas it helps us to understand our own developmental psychology.k
Personality theorists should study normal individuals
All behavior is interactive
The person must be studied in terms of interactions with their environment
The brain is the locus of personality
There is a biological basis to personality
Definition of Personality
1- Personality is an abstraction formulated by a theorist.
2- It refers to series of events that ideally span over life time from childhood to adulthood
3-It reflects novel, unique, recurrent and enduring patterns of behaviours – his education and training .
4- Personality is located in brain- imagination, perception
5.Personality comprises the person’s central organizing and governing processes, whose function is to
Resolve conflicts,
Satisfy needs, and
Plan for future goals.
” Emotions are complex psychological states involving three distinct components: a subjective experience, a physiological response, and a behavioral or expressive response”
"Discovering Psychology," by Don Hockenbury and Sandra E. Hockenbury
In 1972, psychologist Paul Ekman suggested that there are six basic emotions that are universal throughout human cultures: fear, disgust, anger, surprise, joy, and sadness.
In the 1980s, Robert Plutchik introduced another emotion classification system known as the wheel of emotions. This model demonstrated how different emotions can be combined or mixed together, much like the way an artist mixes primary colors to create other colors.
Plutchik proposed eight primary emotional dimensions: joy vs. sadness, anger vs. fear, trust vs. disgust, and surprise vs. anticipation.
These emotions can then be combined to create others, such as happiness + anticipation = excitement.
In 1999, Ekman expanded his list to include a number of other basic emotions, including embarrassment, excitement, contempt, shame, pride, satisfaction, and amusement
Anger is an intense emotion you feel when
Something has gone wrong or
Someone has wronged you.
It is typically characterized by feelings of
Stress,
Frustration, and
Irritation.
Anger is a perfectly normal response to frustrating or difficult situations.
Anger only becomes a problem when
It’s excessively displayed and
Begins to affect your daily functioning and the way you relate with people.
Anger can range in intensity, from a slight annoyance to rage.
It can sometimes be excessive or irrational.
In these cases, it can be hard to keep the emotion in check and could cause you to behave in ways you wouldn’t otherwise behave.
Cognitive distortions are
Negative or irrational patterns of thinking.
Simply ways that Impostor Syndrome convinces us to believe things that aren’t really true.
Inaccurate thought patterns that
Reinforce our negative self perception and
Keep us feeling bad about ourselves
These negative thought patterns can play a role in
Diminishing our motivation,
Lowering our self-esteem
Contributing to problems like
Anxiety,
Depression, and
Substance use.
Trauma Bonding is the attachment an abused person feels for their abuser, specifically in a relationship with a cyclical pattern of abuse.
Is created due to a cycle of abuse and positive reinforcement
After each circumstance of abuse, the abuser professes love, regret, and trying to make the relationship feel safe and needed for the abused person.
Hence Abused
Finds leaving an abusive situation confusing and overwhelming
Involves positive and/or loving feelings for an abuser
Also feel attached to and dependent on their abuser.
Emotional abuse involves controlling another person by using emotions to Criticize , Embarrass ,Shame ,Blame or
Manipulate .
To be abusive there must be a consistent pattern of abusive words and bullying behaviours that Wear down a person’s Self-esteem and Undermine Their mental health.
Most common in married relationships,
Mental or emotional abuse can occur in any relationship—including among
Friends
Family members and
Co-workers
Attachment-related patterns that differ between individuals are commonly called "attachment styles."
There seems to be an association between a person’s attachment characteristics early in life and in adulthood, but the correlations are far from perfect.
Many adults feel secure in their relationships and comfortable depending on others (echoing “secure” attachment in children).
Others tend to feel anxious about their connection with close others—or prefer to avoid getting close to them in the first place (echoing “insecure” attachment in children).
Borderline personality disorder, characterized by a longing for intimacy and a hypersensitivity to rejection, have shown a high prevalence and severity of insecure attachment.
Attachment styles in adulthood (similar to attachment patterns in children):
Secure
Anxious-preoccupied (high anxiety, low avoidance)
Dismissing-avoidant (low anxiety, high avoidance)
Fearful-avoidant (high anxiety, high avoidance)
Conduct disorder is an ongoing pattern of behaviour marked by emotional and behavioural problems.
Ways in which Children with conduct disorder behave are
Angry,
Aggressive,
Argumentative, and
Disruptive ways.
It is a diagnosable mental health condition that is characterized by patterns of violating
Societal norms and
Rights of others
It's estimated that around 3% of school-aged children have conduct disorder and require professional treatment .
It is more common in boys than in girls.
Oppositional defiant disorder (ODD) is a psychiatric disorder that typically emerges in childhood, between ages 6 and 8, and can last throughout adulthood.
ODD is more than just normal childhood tantrums
Frequency and severity of ODD causes difficulty at home and at school.
Children with ODD also struggle with learning problems related to their behavior.
Two types of oppositional defiant disorder:
Childhood-onset ODD:
Present from an early age
Requires early intervention and treatment to prevent it from progressing into a more serious conduct disorder
Adolescent-onset ODD:
Begins suddenly in the middle- and high-school years, causing conflict at home and in school
There have been at least 13 different types of intelligence that have been identified so far.
These different ways of being smart can help people perform in different areas from their personal life, business, to sports and relationships.
Attachment is an emotional bond with another person. John Bowlby described attachment as a "lasting psychological connectedness between human beings.“
Earliest bonds formed by children (with caregivers) have a tremendous impact that continues throughout life and Attachment so developed
Serves to keep the infant close to the mother, thus improving the child's chances of survival.
Are innate drive Children are born with and is a product of evolutionary processes
Emerges and are regulated through the process of natural selection,
Are characterized by clear behavioural and motivation patterns.
Nurturance and responsiveness were the primary determinants of attachment.
Children who maintained proximity to an attachment figure were more likely to
Receive comfort and protection, and
More likely to survive to adulthood.

The term ‘Moonlighting’ became popular in America when people started working a second job in addition to their regular 9-to-5 jobs. Since the rise of the work-from-home concept during the pandemic, employees got free time after work hours. While some took up their hobby in their free time, others started searching for part-time jobs. Especially in the IT industry, employees took up two jobs simultaneously and took advantage of the remote working model. This concept of working for two companies/organisations is referred to as moonlighting.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Overview on Edible Vaccine: Pros & Cons with Mechanism
Led codes and standards &Advantages
1. LED codes and standards
Clients are asking lighting designers to help them save on energy costs, and
replacing fluorescent, HID, or other lights with LEDs is in high demand. This article
looks at the codes and guidelines that define LED use.
Tom Divine, PE, LEED AP, Smith Seckman Reid Inc., Houston
04/19/2016
Learning objectives:
Outline the codes and standards that dictate designing with LEDs.
Compare and contrast the benefits and drawbacks to LEDs.
Evaluate the use of lighting controls.
Nearly all commercial facilities in the United States are governed by one of
three energy-conservation codes:
ASHRAE Standard 90.1: Energy Standard for Buildings Except Low-
Rise Residential Buildings
International Energy Conservation Code (IECC) from the International
Code Council
California Title 24: California Energy Code.
For this article, these codes will be referenced as ASHRAE 90.1, IECC, Title
24, and collectively as "the codes."
Each code describes requirements for lighting, in terms of the total lighting
power allowed, along with prescriptive requirements regarding lighting
controls and operation. Most jurisdictions require that a project design
complies with ASHRAE 90.1 or IECC, and California projects are governed by
Title 24.
2. ASHRAE 90.1 can be considered the standard energy code for the United
States. The federal Energy Policy Act of 2005 (EPAct), as amended, requires
that states adopt an energy code at least as stringent as whatever edition of
ASHRAE 90.1 is found to be most stringent by the Department of Energy
(DoE). Title 24, directly enforceable only in California, operates to some
degree as a bellwether code—significant changes to ASHRAE 90.1 and IECC
often appear first in Title 24 and then migrate to future editions of the other
two codes.
These codes and their predecessors can exert substantial influence on
lighting markets. For example, California Title 20, 1605.1(l), included by
reference in California Title 24, requires that exit signs consume no more than
5 W per face, echoing the requirements of the EPAct. That level is difficult to
achieve with fluorescent lamps, and impossible with incandescent lamps. The
requirement had the effect of creating a de facto requirement for LED drivers
in exit signs. Today, practically every exit sign uses LEDs as its light source.
The primary intent of the codes is to ensure that the built environment uses
less energy than it would in their absence. One of their secondary purposes is
to foster technologies that show promise for future energy conservation. LED
lighting currently looks to be one of those technologies, and we can expect the
codes to include requirements that foster its development and acceptance to
the extent that those requirements are reasonably achievable and don't
conflict with the codes' primary purpose.
3. This article isn't intended to describe how to achieve compliance with these
codes. Each code describes a Byzantine maze of decision trees, exceptions,
and alternate compliance methods. A thorough treatment of any of them is
well beyond the scope of this article. Rather, this article qualitatively describes
some of the requirements of the codes covering lighting systems, with
particular emphasis on new requirements in common among them, and how
those requirements affect design decisions regarding LED lighting.
LED benefits and drawbacks
LED lighting offers a number of advantages over more traditional
technologies. They exhibit very long lifetimes as compared with fluorescent
lamps, and consequently have lower maintenance requirements. They're
robust and much more resistant to physical damage than fluorescent lamps.
They're insensitive to cycling, and can be energized repeatedly without
reducing their life. Their ultraviolet and infrared emissions are extremely low
compared with other sources. And, they don't contain environmentally
troublesome ingredients, making their ultimate disposal a simple matter.
LED lighting also brings advantages that are specifically interesting in regard
to energy conservation:
Efficiency: The luminous efficacy of LED luminaires is generally
competitive with fluorescent fixtures, and fixtures with high-end LED
emitters can exceed the efficacy of the best fluorescent fixtures. In
addition to direct energy savings, high efficiency reduces HVAC costs
during heating seasons and in interior zones.
Dimmability: LEDs are easily dimmable, as a consequence of the
technology used to provide the constant direct current (dc) that drives
them. Adding dimming capability to an LED fixture is inexpensive as
compared with fluorescent fixtures.
Controllability: LEDs come to full brightness almost immediately after
they're energized, while fluorescents can take many seconds or a few
minutes to reach maximum output.
LEDs are much less sensitive to cold temperatures than fluorescent
lamps, making them well suited for outdoor use.
At the same time, LEDs bring significant disadvantages:
LED lighting is generally more expensive than fluorescent lighting in
terms of similar effective light output, build quality, and appearance.
4. The market for LED fixtures and lamps is, if not in its infancy, certainly
preadolescent. There are few standards, few long-term manufacturers,
and limited information. Most LED emitters have life ratings that are
considerably longer than the age of the product. Producers can enter
and exit the market quite quickly, and there's often little reason to
believe that a particular device will still be in production when the first
unit fails and has to be replaced. These facts can lead some facility
owners to have a level of reluctance to invest in this technology.
Fluorescent technology has had the lion's share of the commercial lighting
market for decades, and pricing and performance have been relatively stable
for years. The prevailing industry view is that most of the available
improvements and economies of scale have already been realized for
fluorescent lighting and few, if any, efficiency enhancements or cost
reductions are forthcoming for that technology. The prevailing view of LED
technology is that efficiency will improve and costs will go down as market
share increases and the technology matures. Typical luminous efficacies for
LED luminaires currently range from about 50 to 100 lumens/W, which is
comparable to linear fluorescents. Projections for future efficacy run as high
as 225 lumens/W. Whether that level of performance is actually achievable
remains to be seen.
Lighting power allowances
The allowable lighting power densities of the codes are approximately aligned
with one another. Allowable densities are generally reduced from previous
versions, but not dramatically, as the code-makers have become concerned
about maintaining the quality of the indoor environment at low lighting power
levels. Consequently, most of the improvement in buildings' lighting efficiency
will come from enhanced control requirements, rather than lighting power
density limits. The prescribed levels are roughly as achievable with
fluorescent lighting as with LED, though high-end LED fixtures may provide a
bit better headroom.
Interior lighting controls
All of the codes require some form of automatic shut-off for most interior
lighting, accomplished with occupancy sensing or with time-based controls.
ASHRAE 90.1 and Title 24 require that manual controls be accessible to
occupants for all interior lighting. For most spaces, all the codes require a
"partial-on" function, limiting the lighting power of the first stage to 50% of the
connected lighting power or less. And, all require light-reduction controls that
5. offer at least one control option with substantially reduced lighting power.
ASHRAE 90.1 requires a reduction of 30% to 70% while Title 24 and IECC
require at least 50% reduction. All of the codes require that light-reduction
controls be available to occupants.
Lighting power-reduction controls can be accomplished by dimming all the
luminaires, by switching some luminaires off completely, or by selective
control of a portion of the lamps in each luminaire. The codes require that the
lighting is reasonably uniform when lighting power controls are active.
Lighting power reduction controls provide a slight push toward selection of
LED luminaires. For volumetric applications, these controls can generally be
implemented with fluorescents by judiciously switching lamps in multilamp
fixtures. The uniformity requirement nudges the selection criteria toward LED
devices, especially for single lamp fixtures. It's easy to maintain uniformity by
dimming all the fixtures together. The inherent dimming capability of LED
fixtures makes them an attractive solution for lighting power controls.
IECC offers a path to compliance that includes a requirement that all fixtures
be continuously dimmable, with individual addressability of fixtures where it's
available for the fixture class (C406.4, "Enhanced digital lighting controls").
This path is not strictly required, as it is one of a menu of options for
compliance. An across-the-board requirement for continuous dimming will
strongly push luminaire selection toward LEDs
