Social network analysis is a method by which one can analyze the connections across individuals or groups or institutions. That is, it allows us to examine how political actors or institutions are interrelated.
This presentation on evaluating public relations campaigns is an excerpt from a presentation conducted by Shrita Sterlin of Penn Strategies. Shrita conducted this presentation at a forum held by the Center for Nonprofit Success on November 3, 2011 in Washington, DC. The presentation explores best practices for creating data-driven public relations campaigns in nonprofit organizations; provides tips for quantifying social change efforts; and demonstrates ways to measure the process and results of public relations campaigns.

Indexing theory of political mass communication - Prepared by Fiza Zia Ul HannanDr. Fiza Zia Ul Hannan
Inspired by the work of Hallin, W. Lance Bennett introduced the “Indexing” theory in his article “Toward a Theory of Press-State Relations in the United States” (1990). The theory also known as indexing hypothesis and indexing model was proposed on the basis of a study that was conducted on the New York Times’ coverage of the United States’ involvement with Nicaraguan contras. Bennett’s preliminary indexing hypothesis states: “mass-media news professionals tend to ”index” the range of voices and viewpoints in both news and editorials according to the range of views expressed in the mainstream government debate about foreign affairs topics” - (Bennett 1990).
Social network analysis [SNA] is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge entities. SNA provides both a visual and a mathematical analysis of human relationships.
The sole purpose of sharing these slides are to educate the beginners of IT and Computer Science/Engineering. Credits should go to the referred material and also CICRA campus, Colombo 4, Sri Lanka where I taught these in 2017.

This is a slide on Information Systems. Information systems are interrelated set of components working together to collect, process, store and provide information for decision making. Every organisation needs an information system hence the need for this slide. The target audience are students in high school (Ghana) studying elective ICT, however, anybody interested in Information and Communications Technology will find this useful.

data and judgments to assist a manager in his
decision making”
Assumption: that the system is computer-based
and extends the user’s capabilities.

Working Definition of DSS
A DSS is an interactive, flexible, and adaptable CBIS,
specially developed for supporting the solution of a
non-structured management problem for improved
decision making. It utilizes data, it provides easy user
interface, and it allows for the decision maker’s own
insights
DSS may utilize models, is built by an interactive
process (frequently by end-users), supports all the
phases of the decision making, and may include a
knowledge component

Characteristics and Capabilities of
DSS(Figure 3.1)
1. Provide support in semi-structured and unstructured
situations, includes human judgment and
computerized information
2. Support for various managerial levels
3. Support to individuals and groups
4. Support to interdependent and/or sequential decisions
5. Support all phases of the decision-making process
6. Support a variety of decision-making processes and
styles

7. Are adaptive
8. Have user friendly interfaces
9. Goal: improve effectiveness of decision making
10. The decision maker controls the decision-making
process
11. End-users can build simple systems
12. Utilizes models for analysis
13. Provides access to a variety of data sources,
formats, and types
Decision makers can make better, more consistent
decisions in a timely manner
