MANAGEMENT OF BIOCHEMICAL RECURRENCE AFTER RADICAL PROSTATECTOMY & RADIATION ...GAURAV NAHAR
This document discusses evaluation and management of prostate-specific antigen (PSA) recurrence after radical prostatectomy for localized prostate cancer. It defines PSA recurrence as a rising PSA level after surgery without clinical or radiographic evidence of disease. A PSA level of 0.2 ng/mL or higher is commonly used to define recurrence. Factors like preoperative PSA, Gleason score, and pathological stage can predict recurrence risk. While tests cannot reliably determine the site of recurrence at low PSA levels, treatment may involve observation, salvage radiation for presumed local recurrence, or hormone therapy for presumed metastases. The document outlines guidelines for these treatments and concludes that patients can be stratified into low, intermediate, and high risk groups

David K. Berlo was an American communication theorist who developed the SMCR model of communication and later Media Dependency Theory. He argued that individuals rely more heavily on media as sources of information, which influences their attitudes and behaviors. Berlo's Media Dependency Theory posited that the relationship between media and their audiences is one of dependency, with receivers depending more on media over time for information they need to function in society.
The document provides tips for using social media effectively for business. It recommends establishing specific goals and objectives, learning about your target audience, and choosing social media channels strategically. The key is to regularly connect with your audience by sharing relevant and valuable content that adds value for them. Over time, these small daily efforts can lead to major success through social media.
Mass media is ubiquitous and influences people's lives daily through economic, social, and cultural means. Most mass media is now wireless, allowing people to stay connected anywhere. Technological developments have changed how mass media is delivered, moving from wired to wireless transmission of electronic signals. Mass media both reflects and shapes politics, society, and culture.
The Media Dependency Theory proposes that the more dependent an individual is on media to have their needs met, the more important media will be to that person. The theory was developed by Sandra Ball-Rokeach and Melvin DeFleur and is widely applicable today given society's overwhelming use of media. There is debate around what exactly causes media dependency, with some pointing to factors like age, occupation, or geographic location.
Is Twitter an Individual Mass Communication Medium?Martin Ebner
This document discusses whether Twitter can be considered an individual mass communication medium. It adapts traditional communication models like interpersonal, group, organizational, and mass communication to Twitter. It concludes that Twitter enables mass communication through public, indirect, unilateral tweets sent through the Twitter application to a wide audience. Unlike traditional mass media, Twitter allows individuals to participate in mass communication.
This document discusses how social media can be used to spread religious messages and faith more effectively. It explains that social media allows for dialogue rather than monologue, and people are more likely to trust recommendations from other users than advertisements. When religious groups use popular social media sites like Facebook, Twitter and YouTube, their messages can quickly reach millions of people. This wide reach helps spread faith and improves transparency and inclusion in religious communication. Implementing social media marketing helps make religious messages more fun and appealing to youth.
The document discusses how television and films can influence a person's beliefs about God. It provides examples of different types of media content that may positively or negatively portray religion and religious believers. Students are prompted to consider how specific films or TV programs might affect belief in God by analyzing how religion is depicted and whether it is presented realistically. The document also provides sample exam questions that require students to discuss whether religious TV or radio programs encourage belief in God and consider different perspectives on this issue.
This document provides an introduction to using social media for politicians. It explains how social media platforms have evolved to allow two-way communication and user generated content. The document gives advice for politicians on starting social media accounts, observing communities, engaging with their network, and sharing both internal and external content to build their online presence and connect with voters.
HEALTH COMMUNICATION & MASS MEDIA IN PUBLIC HEALTHAminu Kende
The media is an important ally in any public health situation. It serves the role of being a source of correct information as well as an advocate for correct health behaviors. But before the media can take on that role, it needs to understand the virus, the issues surrounding it, policy and practices, and finally, recommended correct behaviors. Role of mass media in public health
Media is a tool for mass communication that has traditionally included television, radio, magazines, newspapers, and more recently the internet. It plays a big role in society by informing and entertaining people but can also influence attitudes, behaviors, and opinions if not approached critically. Two famous cases in India, the Jessica Lal murder case and the Nirbhaya gang rape case, demonstrate how the media can have a positive impact by raising public awareness, mobilizing protests, and helping to ensure justice is delivered. While the media can educate and spread knowledge, it is important for individuals to think critically about the messages they receive and not be passively manipulated.

Mass media has powerful effects on body image and society. It transmits information through various technologies to reach a wide audience. Regarding body image, advertising influences how people see themselves and their bodies, even in children as young as three. It promotes thin ideals that make people question their appearance and buy more products. For society, media can educate but also desensitize people to violence and blur reality with fiction, especially impacting children. It shapes beliefs and influences teens seeking acceptance and success. Overall, mass media has become central to modern society.
The document discusses how mass communication is defined as technology-assisted transmission of messages to mass audiences. It notes that 68.8% of our waking hours are exposed to media messages through various forms of mass communication and social media. Developing media literacy skills is important to recognize how media can influence our views of the world and be able to analyze and evaluate different media messages critically.

It provides an overview of key figures, theories, and landmark studies that helped shape the field. It also examines ongoing debates around defining the boundaries and subject matter of media studies and how it relates to other disciplines.
Uses and gratifications theory posits that audiences actively seek out specific media to satisfy needs and motives. It focuses on why and how people use media rather than how media affects people. The theory assumes audiences are goal-oriented, proactively choose media, and can provide accurate insights into their own media use. Early studies identified motives like emotional gratification and wishful thinking. Later work organized motives into categories like diversion, social interaction, identity, and surveillance. The theory holds that social contexts shape audiences' needs and media use. It also argues people construct their own meanings from media rather than being passively influenced.
Understanding Media Studies "Mapping the Field" PresentationShannon Mattern
The document discusses the history and development of communication studies as an interdisciplinary field. It touches on key influences from other disciplines like humanities, social sciences, and professions. The field has struggled with defining its boundaries and subject matter but is characterized by its interdisciplinary and popular approach to organizing inquiry into areas like media effects, democracy and culture, and ideology and power.
Audience uses and gratifications theorycaitlincmedia
The Uses and Gratifications Theory suggests that audiences actively seek out specific media to fulfill needs, rather than media directly influencing audiences. It proposes that media use fulfills needs of identity, education, entertainment, and social interaction. While it provides insights, it has been criticized for ignoring media's unconscious influence and not holding media accountable for its content. The theory evolved over three stages from the 1940s by examining why audiences select certain media and connecting motivations to gratifications received.
This document provides an overview of key readings and themes for a university course on media studies and the active audience. It discusses early research on media effects that viewed audiences as passive. It then covers developments like Hall's encoding/decoding model, Morley's Nationwide study, and the uses and gratification perspective that saw audiences as active. More recent topics examined include audience engagement with digital media and examples of fan cultures interacting with television texts across multiple platforms.
This document outlines seven traditions or perspectives in the field of communication theory: socio-psychological, cybernetic, rhetorical, semiotic, socio-cultural, critical, and phenomenological. It also discusses three traditions proposed by Alvarado & Boyd-Barrett and six aspects of communication outlined by the British Film Institute. Finally, it summarizes seven traditions of communication proposed by Boyd-Barrett & Newbold, including mass society/functionalism/pluralism, media effects, political economy, public sphere, media occupations, cultural hegemony, and feminism. The document provides an overview of different theoretical frameworks for understanding communication.

The discussion considers implications around viewer interpretation and
A Review Of Media Effect Theories And Their Extension To Digital MediaYolanda Ivey
This document provides an overview of media effect theories from early theories of direct unidirectional effects to later more complex reciprocal theories. It discusses four phases of media effect theories: 1) Significant Effect Phase where media were seen as directly shaping opinions, 2) Minimal/Limited Effect Phase where media effects depended on individual predispositions, 3) Strong Effect Rediscovered Phase where long-term cultivation effects of television were studied, 4) Reciprocal Effect Phase where interactive digital media allow for two-way effects between media and audiences. The document aims to map how theories have evolved over time and discuss extending theories to digital media.
6.4 - Relationship between Producers and Audience.pptxJamesDixon10403
This document discusses the relationship between media producers and audiences. It begins by discussing how we should think about what people do with media rather than what media do to people. It then discusses two main concerns regarding how audiences engage with media texts: whether texts have a single meaning or multiple meanings, and what factors need to be considered in understanding a text's meanings. The document goes on to explain four communication theories - the hypodermic needle theory, reinforcement theory, uses and gratification theory, and two-step flow theory. It provides a brief overview of each theory, including their perspectives on audiences and influence.
This document summarizes several key theories in media studies:
1) Active audience theory which holds that audiences can understand media messages differently based on their own experiences and can critically analyze or reject messages.
2) Uses and gratification theory which examines how individuals use mass media to fulfill personal needs such as entertainment or information.
3) Obstinate audience theory which found that audiences filter and distort messages to fit their own views rather than passively accepting one-way influence.
4) Cultural studies theories which emphasize the active role of audiences in interpreting media texts based on their social positions and backgrounds.
The document provides an overview of several mass communication theories, beginning with the hypodermic needle theory. This theory proposed that media had a direct and powerful effect on passive audiences. However, the two-step flow theory later emerged from election studies, finding that opinion leaders and interpersonal communication were more influential than direct media effects. This led to the two-step flow model, where information spreads from media to opinion leaders and then to less active individuals.
This document discusses the four eras of mass communication theories:
1) Era of mass society theory from 1850-1940 where new media was seen as disruptive.
2) Era of scientific perspective from 1940-1950 where Lazarsfeld conducted experiments showing media had limited effects.
3) Era of limited effects from 1950-1960s where research supported this perspective.
4) Era of cultural criticism from 1960-1980s where European theorists argued media enabled elites to maintain power. Theories discussed in each era include propaganda theory, limited effects theory, agenda setting theory, and cultivation theory.
This document provides an overview of major communication theories developed since the early 20th century. It discusses early theories like rhetorical theory and symbolic interaction theory. It then covers research in the 1930s-40s that studied the effects of media like film, radio and newspapers. This led to theories around two-step flow of communication, uses and gratifications, and limited effects of media. The document also summarizes cognitive dissonance theory, agenda setting theory, spiral of silence theory, cultivation theory, dependency theory and other influential communication theories.
The document discusses the theory of the active audience, which posits that audiences play an active role in interpreting media messages rather than passively accepting them. It outlines the development of this theory over time, from early models that viewed audiences as passive to Stuart Hall's encoding/decoding model and other research emphasizing that audiences filter messages through their own experiences and can negotiate or oppose the dominant meanings. The document also discusses criticisms of and ongoing questions around the active audience theory.
Wilbur Schramm is considered the founder of communication study as an academic field. During WWII, he collaborated with other social scientists through the Office of Facts and Figures and helped establish communication research. He went on to head communication programs and research institutes at the University of Iowa, University of Illinois, and Stanford University, developing curricula that applied social science perspectives to the study of communication. Through his leadership positions, books synthesizing communication research, and influence on other scholars, Schramm played a pivotal role in establishing communication as a new interdisciplinary academic field in the postwar period.
The persistent case of media effects research [lecture 2011]Rob Jewitt
1. The document traces the historical trajectory of media effects research through four phases: from viewing media as all-powerful, to its effects being challenged, to powerful media being revisited, to negotiating how audiences make meaning from media.
2. Across these phases, research approaches and theories have shifted from behaviorism and conditioning, to cultivation analysis and social learning theory, to examining how audiences actively interpret media rather than being passive receivers.
3. A key challenge is that it is difficult to isolate the specific influence of media from other variables on behaviors, and research approaches each have their limitations such as lack of external validity or real-world application.
This document discusses the divide between "hands-on" and "logo-centric" approaches to visual sociology. It argues that hands-on practitioners tend to focus narrowly on documentary photography while logo-centric practitioners take a broader theoretical approach conceptualizing vision and representation as sites of culture and knowledge production. The document traces the theoretical roots of these approaches in continental European sociology, North American sociology, and British cultural studies. It aims to contextualize visual inquiry and help unify disparate yet related practices in the field.
This document discusses the divide between "hands-on" and "logo-centric" approaches to visual sociology. It argues that hands-on practitioners tend to focus narrowly on documentary photography while logo-centric practitioners take a broader theoretical approach informed by traditions from continental European sociology and British cultural studies. The document traces the theoretical influences and origins of these different approaches, noting that hands-on visual sociology developed in North America while logo-centric traditions have roots in Europe. It suggests these divisions are beginning to break down as visual sociology becomes more popular and interdisciplinary.

2) Partnering with suppliers and distributors is important to improve performance across the entire value delivery network and build customer relationships.
3) Developing a customer-driven marketing strategy involves market segmentation, targeting, and positioning to meet the distinct needs of targeted customer groups.
The document provides an overview of marketing concepts including:
- Marketing is a process of creating value for customers and building relationships to capture value in return.
- Understanding customer needs, wants, demands and the marketplace is key.
- Designing a customer-driven marketing strategy involves selecting target customer segments and developing an appropriate value proposition.
- Integrated marketing plans use the "4 Ps" (product, price, place, promotion) to implement strategies and communicate value to customers.
- Building customer relationships through customer relationship management (CRM) and delivering superior customer value and satisfaction is important.
Asia is the largest continent, covering one third of the Earth's land area. It is home to over 4 billion people and contains immense geographic, cultural, and economic diversity. Major realms include East Asia, Southeast Asia, South Asia, West Asia, and Central/North Asia. Asia is rich in natural resources like coal, oil, natural gas, and many metals. It is also a major agricultural producer, especially of rice, wheat, tea, and tropical crops. However, population growth and urbanization are putting pressure on resources and the environment in many Asian countries.
The document outlines the history of broadcasting from its origins to modern times. It discusses key inventors and innovations that led to the development of radio and television technologies. Some of the earliest developments include Maxwell's theory of electromagnetic waves in 1855 and Marconi sending the first wireless signal in 1901. Over decades, inventors continued improving the technologies, with the first radio broadcasts in the early 1900s and commercial television debuting in 1939. Both media grew rapidly in popularity and changed how people received information and entertainment, helping to shift societies with their widespread adoption.
The document discusses different types of texts and their defining features. It describes five main text types: narrative, descriptive, instructional, argumentative, and expository. For each text type, it provides examples and discusses common grammatical features that characterize each type, such as the use of tense, pronouns, conjunctions, and other language elements.
The document discusses different types of reading categorized into reading according to purpose, reading performance/rate of understanding, reading instruction programs, and the PISA reading framework. It describes various reading types such as skimming, scanning, intensive reading, extensive reading, and remedial reading. It also discusses reading strategies like shared reading, guided reading, and strategic reading.
Reading is an active process that involves a transaction between the reader's background knowledge and the text. It is constructive, as readers use their schema to make inferences and derive meaning. Reading comprehension depends on the reader's prior knowledge, ability to understand the language of the text, and ability to understand the message. Readers use both top-down and bottom-up processing, applying their expectations while taking in elements from the text. Multiple types of knowledge, such as syntactic, morphological, world, and topic knowledge, help readers make sense of a text.
The document summarizes 5 stages of reading development from early childhood through adulthood. Stage 1 (grades 1-2) focuses on decoding letters and associating them with sounds. Stage 2 (grades 2-3) focuses on consolidating decoding skills and reading for fluency. Stage 3 (grades 4-8) requires using prior knowledge to understand new concepts. Stage 4 (high school) includes considering multiple viewpoints. Stage 5 (college and beyond) uses reading to synthesize one's own knowledge with others'.
George Gerbner et al. argue that television is a powerful cultural influence that shapes viewers' perceptions of the world through two processes: mainstreaming and resonance. Mainstreaming occurs when heavy television viewers' perceptions are dominated by television's messages, erasing other distinctions. Resonance occurs when television messages align with or reinforce viewers' real-world experiences. Through analysis of surveys using a "Mean World Index" and "Danger Index", they found heavy viewers had more fearful and distrustful views of the world than light viewers, demonstrating television's role in cultivating perceptions.
George Gerbner was a media researcher who studied the effects of television violence for over 30 years. He founded the Cultural Indicators Project in 1968 to analyze television content and its effects on viewers' perceptions of the world. Gerbner developed cultivation theory, which proposes that heavy television viewers come to see the real world as similar to the fictional world portrayed on TV. The Cultural Indicators Project monitored television programming to measure the amount of violence and how it impacted viewers' beliefs about society.
The document outlines the three mental operations of reasoning: simple apprehension, judgment, and reasoning. Simple apprehension is grasping a thing without affirming or denying it. Judgment is joining two apprehended terms and affirming or denying them. Reasoning is drawing a conclusion from a set of valid premises. It then provides examples and structural features of each operation.
Ideas are the building blocks of knowledge that arise from sensory experiences and mental processes like abstraction. An idea has two main properties: comprehension and extension. Comprehension refers to the conceptual elements that make up the idea's meaning, while extension refers to the range of individual objects the idea applies to. Ideas can be classified according to their structure, subject, relation to other ideas, and scope of application. The types of ideas provide a framework for understanding concepts and their logical relationships.
- Hadley Cantril was a psychologist born in Utah who received his PhD from Harvard and joined the faculty of Princeton University, where he later became chairman of the psychology department. Some of his most influential works included research on public opinion and mass communication.
- Orson Welles was an American actor, director and producer best known for his films Citizen Kane and The Magnificent Ambersons. His 1938 radio broadcast of The War of the Worlds, presented as a news bulletin, caused widespread panic among listeners who thought the fictional Martian invasion was real.
- The broadcast was so believable and frightening because it played on the anxieties and vulnerabilities of Americans during the Great Depression as war loomed in Europe

A Strategic Approach: GenAI in EducationPeter 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.

8. The uses and gratifications approach
examines the process of communication
starting from the audience members’
individual perceptions.
It investigates why individuals choose to use
media.
Identifies how people use media to satisfy
their needs.
It does not consider the power of media;
more audience-centered.

10. 1. A basically similar methodological approach whereby
statements about media functions were drawn out
from the respondents in an essentially open-ended way.
2. They shared a qualitative approach in their attempt to
group gratification statements into labelled categories.
3. They did not attempt to explore the links between
gratifications.
4. They failed to search for the interrelationships among
the various media functions.
5. The aforementioned studies did not result in an

12. Five assumptions were set that served as
guidelines for conducting uses and
gratifications research, based from
Lundberg and Hulten’s model:
1. The audience is active.
2. The audience member links his/her need
gratifications to media content.
13. 3. The media compete with other sources of
need satisfaction.
4. People are aware of their needs and can
indicate them media researchers.
5. Judgments about the value of what people
attend to should not be part of the research
on uses and gratifications.
14. The assumptions do not, and were not
intended to, provide a formal theory. They
were only intended to “explain something of
the way in which individuals use
communications among other resources in
their environment, to satisfy their needs and
achieve goals.”
They provided a broad set of ideas that
helped the uses and gratifications as an
emerging perspective.

19. Gratifications and Needs
The study of mass media use suffers at present from
the absence of a relevant theory of social and
psychological needs.
Issue: the long-standing problem of social and
psychological science: how to (and whether to bother
to) systematize long lists of human and societal
needs.
Thus far, gratifications research has stayed closed to
what we have been calling media-related needs (in
the sense that the media have been observed to
satisfy them, at least in part).
20. Sources of Media Gratifications
Audience gratifications can be derived from at least
three distinct sources: media content, exposure to the
media per se, and the social context that represents
the situation of exposure to different media.
Researcher Need Media
Waples, Berelson, Need to relax or Television
and Bradshaw (1940) kill time Radio
Berelson (1949) Need to feel that
one’s spending time
worthwhile
Mendelsohn (1964) Need to structure Radio
one’s day
21. Each medium seems to offer a unique combination of:
(a) characteristic contents
(b) typical attributes (Print vs. Broadcasting mode of
transmission, Reading vs. Audio or audio-visual
modes of reception)
(c) typical exposure situations (Home vs. Out-of-home,
Alone vs. With others)
Issue: what combinations of attributes may render
different media more or less adequate for the
satisfaction of different needs.
22. Gratification and Media Attributes
Two ways of division of labour among the
media for the satisfaction of audience
needs: taking media attributes as the
starting point or utilizing the latent
structure of needs as a point of departure.
23. 1. Media attributes differ and are more likely to serve
different or similar needs
Researcher Findings Type of Media
Robinson (1972) Interchangeability Television
of media for learning Print
purposes
Katz, Gurevitch and Haas Five media in Books+Newspaper = Books+Cinema
(1973) circumplex with their Radio+Newspaper = Radio+Television
functional similarities
(Books-newspapers- Books+Newspaper = technological
radio-television- and informational function
cinema-books) Books+Film = aesthetic function
Radio+Television = technology &
entertainment function
Radio+Newspaper = information &
reality orientation
24. 2. Needs that are psychologically related or conceptually
similar will equally served by the same media with
similar attributes. Structurally related needs will tend
to be serviced by certain media more often than by
others.
Type of Media Needs
Books + Cinema Self-fulfillment and self-
gratification
Help connect individuals to
themselves
Newspaper + Radio + Connect individuals to society
Television
25. Media dependency theory states that the
more dependent an individual is on the
media for having his or her needs fulfilled,
the more important the media will be to
that person.
It has been explored as an extension of or an
addition to the uses and gratifications
approach .
The theory was created by Melvin DeFleur
and Sandra Ball-Rokeach.
26. DeFleur and Ball-Rokeach described
dependency as the correlating relationship
between media content, the nature of
society, and the behavior of audiences.
They suggested that active selectors’ use of
the media to achieve their goals will result in
being dependent on the media.
27. 1. First, you will become more dependent on
media that meet a number of your needs
than on media that provide just a few.
2. Second is social stability. When social change
and conflict are high, established institutions,
beliefs, and practices are challenged, forcing
you to reevaluate and make new choices. At
such times your reliance on the media for
information will increase. At other, more stable
times your dependency on media may go way
down.
28. The intensity of media dependency depends
on how much people perceive that the
media they choose are meeting their goals.
These goals were into three dimensions
which cover a wide range of individual
objectives:
1. Social and self-understanding
2. Interaction and action orientation
3. Social and solitary play
29. The authors also suggested that more than
one kind of goal can be activated (and
satisfied) by the same medium.
30. Dependency on a specific medium is
influenced by the number of media sources
available to an individual.
Individuals should become more dependent
on available media if their access to media
alternatives is limited.
The more alternatives there are for an
individual, the lesser is the dependency on
and influence of a specific medium.
