This document provides an overview of key concepts from the first 4 chapters of an introductory sociology textbook. It defines sociology as the scientific study of human interactions and relationships. Important early sociologists discussed include Comte, Durkheim, Marx, Weber, and Mills. Durkheim studied how social integration impacts suicide rates. Functionalism, conflict theory, and symbolic interactionism are discussed as major sociological paradigms. The document also distinguishes between micro and macro levels of sociological analysis and emphasizes the importance of avoiding ethnocentrism.

Sociology
Introduction
Definition: Sociology is the systematic study of the relationship between individuals and society.
Sociology, a social science that studies human societies, their interactions, and the processes that preserve and change them.
Humans depend on social institutions and organizations to inform their decision and actions.
The family, community, peer groups, clubs and volunteer associations etc.
Auguste Comte, a French social thinker, Known as Father of Sociology, as he coined the term ‘Sociology’ in 1839.
Theoretical perspectives; Structure-Functionalism, Social-Conflict Perspective and Symbolic Interaction.
1- Structural-Functionalism:
Focuses on consensus and cooperative interaction in social life, emphasizing how the different parts of a society contribute to its overall operation.
The roots of work can be found on the work of Spencer and Durkheim.
Also known as Functionalism Or the functionalist paradigm.
According to this perspective; 1. a social system’s parts are interdependent, for example, family, court, school, the economy, that work together to produce social stability. 2. the system has a healthy state of equilibrium, analogous to a healthy body; 3. a change in one part of system results in change in another part to compensate.
Manifest functions; are obvious and intended.
Latent functions; unorganized and unintended.
Social dysfunctions; undesirable

New Drug Discovery and Development .....NEHA GUPTA
The "New Drug Discovery and Development" process involves the identification, design, testing, and manufacturing of novel pharmaceutical compounds with the aim of introducing new and improved treatments for various medical conditions. This comprehensive endeavor encompasses various stages, including target identification, preclinical studies, clinical trials, regulatory approval, and post-market surveillance. It involves multidisciplinary collaboration among scientists, researchers, clinicians, regulatory experts, and pharmaceutical companies to bring innovative therapies to market and address unmet medical needs.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

• American sociologist. Authored a fundamental principle of sociology
called the Thomas theorem.

• “If people define situations as real, they are real in their
consequences.” (p.3). To understand the social context one must
not only look at what is really going on, but also what people believe
is going on.

stages:
the theological-where religious ideas dominate.
the metaphysical-where systematic thought is stressed.
the positivistic-where science comes to dominate.
4. CHAPTER 1
Emile Durkheim-

• The rate of suicide tended to vary with the degree to which people have
strong ties to their social group.

• Laws, customs, and practices that systematically reflect and produce
racial and ethnic inequalities in a society, whether or not the individuals
maintaining these laws, customs and practices have racist intentions.
Robert K. Merton-

absolute assurance, however, we can frequently predict what most
people will likely do under particular sets of circumstances, but we can
offer no guarantees.

predict the behavior of physical objects.

concentrated at a single point making a very small, dense body. His
research was focused on black holes.

atmosphere, small differences at the beginning of an event can lead to
large differences later.
Topic areas in sociology-
• Age, art, collective behavior, religions, race, and environment.
Paradigms in sociology-
• Functional-
• According to functionalism, society is a system of interconnected
parts that work together in harmony to maintain a state of balance
and social equilibrium for the whole.
• Conflict-
• Emphasize the social, political, or material inequality of a social
group, that critique the broad socio-political system, or that
otherwise detract from structural functionalism and ideological
conservativism.

• a theory that human interaction and communication is facilitated by
words, gestures, and other symbols that have acquired
conventionalized
11. CHAPTER 3

• The study of what PEOPLE do, think and say as they go about their
daily lives.
