The document discusses models of abnormal behavior including biological, psychological, social, and sociocultural models. It notes that the biopsychosocial model recognizes the interaction between these potential causes. Genetic factors can influence brain structure and neurotransmitter functioning, placing individuals at risk for disorders if exposed to stress. However, not all people exposed to the same factors develop the same disorders. The environment can also influence gene expression through interactions and niche-picking behaviors.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Unit 8 - Information and Communication Technology (Paper I).pdfThiyagu K
This slides describes the basic concepts of ICT, basics of Email, Emerging Technology and Digital Initiatives in Education. This presentations aligns with the UGC Paper I syllabus.
2. Categories of Explanations of Abnormal
Behavior
• Biological: genetics, brain anatomy,
biochemical imbalance, central nervous
system, etc
• Psychological: Emotions, thoughts.
Personality, learning
• Social: issues with relationships
• Sociocultural: norms for behavior,
expectations, cultural climate
3. What is a Model?
• Etiology:
– Cause or origin of a disorder
• Model:
– An analogy used by scientists, usually to
describe or explain a phenomenon or process
they cannot directly observe
– Model, viewpoint, and perspective are often
used interchangeably
4. Models (cont-d)
• These one-dimensional views are overly
simplistic:
– Set up a false “either-or” dichotomy between
nature and nurture
– Fail to recognize the reciprocal influences of
one on the other
– Mask the importance of acknowledging the
contributions of all four dimensions in the
origin of mental disorders
5. The Biopsychosocial Model
• Interaction between the possible causes
• Multiple pathways to any disorder
• Not all causes contribute equally to a
disorder
• People exposed to the same factors may
not develop the same disorder
• People exposed to different factors may
develop similar disorders
7. The Structure of the Nervous system
• The Central Nervous System: The brain
and spinal cord
• The Peripheral Nervous System:
• A. The Somatic NS
• B. The Autonomic NS (sympathetic and
para-sympathetic.)
8.
9. Neural Transmission
How is information transmitted in the brain
• Neurons are separated by a gap (synapse)
• The neurons “communicate” at the synapse
• Neuron structure: dendrite, cell-body, axon
• Electrical signals are transmitted chemically
across the synapse
• The signals stimulate the “pockets” at the tip of
the axon to release neurotransmitter
10. Cont-d
• Electro- chemical transmission
• The signal stimulates the vesicles
• Vesicles release the neurotransmitter into the synapse
• Neurotransmitter: Chemical substance released from
a neuron into the synaptic cleft it drifts across the
synapse and is absorbed by the receiving neuron
• The signal “floats” on the neurotransmitter to the next
neuron
• Neurons form inter-connected pathways
11. Cont-d
• The neurotransmitters can either excite or inhibit
the neuron receiving the signal
• The activity of the neuron depends on the
balance between “on” and “off” signals
• Serotonin is implicated in depression and the
OCD.
• Dopamine is implicated in schizophrenia (too
much) and Parkinson (too little)
• GABA (an inhibitory) is implicated in anxiety
12. Biochemical Theories
• Basic premise:
– Chemical imbalances underlie mental
disorders
• Dendrites:
– Receive signals from other neurons
• Axons:
– Send signals to other neurons
15. Abnormalities in Brain Structure
• It is not always possible to connect brain
structures to psychological symptoms
researchers believe that abnormally developed
brain structures
• In 1848 an explosion during the paving of a rail
road caused a metal rod to pierce Phineas Gage
eye socket and to enter his brain
• As a result he showed significant changes in
personality
18. Functions of the brain
• The forebrain:
– Controls all the higher mental functions, such
as learning, speech, thought, and memory
– Thalamus:
• “Relay station;” transmits nerve impulses
throughout brain
– Hypothalamus:
• Regulates bodily drives and body conditions
– Limbic system:
• Involves experiencing and expressing emotions
and motivation
19. Cont-d
• The midbrain:
– Involved in vision and hearing, and along with
the hindbrain, controls sleep, alertness, and
pain
– Manufactures serotonin, norepinephrine, and
dopamine
• The hindbrain:
– Controls heart rate, sleep, and respiration
– Manufactures serotonin
20. Genetic Influences
• Each cell of our body contains 46 chromosomes
• They are made of DNA our genetic material
• A gene is a segment of DNA along the length of
the chromosome that contain the instructions for
forming proteins which in turn determine how
the cell works
• Proteins are the building blocks of our body
22. Genetics (cont-d)
– Genetic abnormalities can come about through:
• Inheritance of particular combinations of genes
• Faulty copying when cells reproduce
• Mutations that a person acquires over the course
of life
• Cells possess the ability to repair many of the
mutations
• The 46 chromosomes are arranged in 23 pairs
• One chromosome from mother and one from
father
23. Genetics (cont-d)
• Genetic makeup plays an important role in
developing abnormal conditions
• Autonomic nervous system reactivity may
be inherited
• Hereditary factors are implicated in
alcoholism, schizophrenia, and depression
24. What do genes do?
• Genes control the manufacturing of
neurotransmitters as well as the way the
neurotransmitters behave at the synapse
• Genes also determine how the brain
structures develop throughout life
• Any factor that can alter the genetic code
can alter how those structures perform
25. Genotype and Phenotype
• The 46 chromosomes are arranged in 23 pairs
• Twenty-two of the pairs are identical (the 23rd
pair is the sex chromosomes XX and XY )
• It means that the same gene is located in the
same place on each of the chromosomes
• Two forms of the same gene are called alleles
• The Genotype is the overall genetic makeup
• The Phenotype is the expression in your
physique and psychological attributes
26. Dominant Recessive Relationship
• The Alleles are related to each other in
Dominant- Recessive relationship
• a dominant allele prevails over a recessive allele
• However, human characteristic and
psychological disorders are polygenic- more than
one gene participates in determining a given
characteristic
• Epigenetics is the attempt to understand how
the environment affects genes to produce
genotypes
28. Genes-environment Interactions
– Interactions between genes and the
environment
– Passive exposure: Children are exposed to
environments that their parents create based
on the parents’ genetic predisposition
– The child’s genetically- based traits elicits
responses from the environment
– Niche-Picking: the child seeks out an
environment that gratifies his/her genetically-
based inclinations
29. Diathesis-Stress Model
• Proposal that people are born with a
predisposition that places them at risk for
developing a psychological disorder if
exposed to certain extremely stressful life
experiences.
30. Assessment of Genetic Factors
– Family inheritance studies: Researchers
compare the disorder rates across relatives
who have varying degrees of genetic
relatedness
– Usually comparing Identical twins who share
100% of their genes to Fraternal twins who
share 50% of their genes
– Studies comparing parents and children are
confounded because of possible
environmental effect
31. Biologically- Based Therapis
• Psychopharmacology:
– Study of effect of drugs on mind and behavior
• Electroconvulsive therapy:
– Application of electric voltage to the brain to
induce convulsions
• Psychosurgery:
– Brain surgery for the purpose of correcting a
severe mental disorder
