The independant variable is low self esteem and the dependant variable is abusive relationships. People who don't value themselves on a high level are more apt to stay in a realtionship that is detremental. It could be mentally, physically, or a combination of the two. Since they don't think of much of themselves, they don't expect others to treat them any better. 2. Self esteem issues are mainly developed in childhood. The independant would be self esteem and the dependant would be childhood. If a parent constantly talks down to a child, that child will in turn start to believe that he or she is in fact worthless. Children are just starting to form emotions and therefore are very impressionable and fragile. Another way that the ego can be broken is taunting peers. Soon the child will grow up with this insecuriety installed in them. Sociology is the study of people and cultures blending together and interacting as a whole in society. Its funtcion is to use that study to predict how to handle future social interactions and social economy. </li></ul>
  9. 10. What do sociologists actually do? This is often a central question that students have when taking an introduction course. Can you answer that question? Go to the American Sociological Association website (asanet.org) and construct a resource handout that answers this question.
  11. 12. Is sociology a scientific discipline. Provide three reasons to support your position. Discipline meaning what? As we discussed, there is prevailing underlying structure of science. The scientific method being the basis for which scientific knowledge is furthered. Science, has two division, applied and pure scientific branches. While last, but not least, science adheres to certain ethical standards that become fundamental to their respective fields. Does the field of sociology contain these three components? YOU NEED TO INCORPORATE WITHIN YOUR ESSAY, TANGIBLE EXAMPLE, TO FULLY ADDRESS THIS. IN OTHER WORDS, FOR THIS ESSAY, IT IS RECOMMENDED THAT YOU SELECT AN EMPIRICAL ARTICLE PERTINENT TO YOUR ASSIGNED GROUP TOPIC, TO SERVE AS THE BACKDROP FOR YOUR DISCUSSION
  12. 13.  Example, where to find suitable topics that are scientifically researchable. PLEASE NOTE HOW SCIENTIFIC RESEARCH ARE VERY PRECISE, IN TERMS OF TARGETTING A PARTICULAR SITUATION (I.E. FORMULATION OF AND TESTING THEREIN OF A HYPOTHESIS) WALL STREET JOURNAL EDUCATION SEPTEMBER 22, 2009 Charter Schools Pass Key Test in Study By JOHN HECHINGER and IANTHE JEANNE DUGAN New York City students who win a lottery to enroll in charter schools outperform those who don't win spots and go on to attend traditional schools, according to new research to be released Tuesday. The study, led by Stanford University economics Prof. Caroline Hoxby, is likely to fire up the movement to push states and school districts to expand charter schools -- one of the centerpieces of President Barack Obama's education strategy.
  13. 20. MANUSCRIPT The New York City Charter Schools Evaluation Project How New York City’s Charter Schools Affect Achievement September 2009 reporting on results through the 2007-08 school year Principal Investigators: Caroline M. Hoxby, Sonali Murarka, Jenny Kang
  14. 21. The Big Picture Capturing the Forest then the Trees Presented at our first class session, we addressed how Sociology is classified as being one of the social sciences. Please name the other social sciences and define these disciplines
  15. 22. Psychology <ul><li>concerned with the behavior, feelings and thoughts of individuals as influenced by social stimuli and/or the person’s physiology. </li></ul><ul><li>The subfield of abnormal psychology is concerned with mental disorders, ranging from psychoses to neuroses </li></ul><ul><li>The applied field of clinical psychology offers direct patient-care mechanisms to treat mental problems in individuals. </li></ul>
  16. 23. Political Science <ul><li>The scientific study of how societies govern the people; </li></ul><ul><li>Analyzes the role of government in regulating people’s behavior, as well as </li></ul><ul><li>How and to what degree it serves to protect societal members of threats (i.e., internal and external) </li></ul><ul><li>as well as influencing/regulating services, goods </li></ul><ul><li>and resources (i.e., energy, commodities, etc.) </li></ul>
  17. 24. Anthropology. <ul><li>Anthropology is a broad social science concerned with the study of humans from a social, biological and cultural perspective </li></ul><ul><li>Physical anthropology divides into two areas, one related to tracing human evolution and the study of primates, and the other concerned with contemporary human characteristics stemming from the mixture of genetic adaptations and culture. </li></ul><ul><li>Sociocultural anthropology is concerned with broad aspects of the adaptation of humans to their cultures— with social organization, language, ethnographic details, and, in general, the understanding of culturally mitigated patterns of behavior </li></ul>
  18. 25. Economics <ul><li>It is perhaps the oldest of the social sciences, with its concern with wealth and poverty, trade and industry </li></ul><ul><li>Concerned with understanding how societis distribute, value and produce and/or import goods and services. </li></ul><ul><li>Microeconomics is largely concerned with issues such as competitive markets, wage rates, and profit margins. Macroeconomics deals with broader issues, such as national income, employment, and economic systems </li></ul>
  19. 26. SOCIAL PSYCHOLOGY <ul><li>A cross-disciplinary social scientific discipline. </li></ul><ul><li>Social psychologist study the relationship between (the) individual(s) in affecting the </li></ul><ul><li>Social groups and societal context as well as how social group affiliation and society </li></ul><ul><li>Affect (the) individual(s). </li></ul>
  20. 27. Sociology <ul><li>It is the social science discipline that study’s human society and social interaction, in group settings. </li></ul>
  21. 29. <ul><li>Science is the study of the material world using human reason. </li></ul><ul><li>Science, by definition, limits itself to what can be observed, measured and verified, known as empiricism. </li></ul>
  22. 30. August Comte <ul><li>The “founder of sociology.” </li></ul><ul><li>Comte believed objective knowledge was attainable only through science rather than religion. </li></ul><ul><li>Positivism is a belief that the world can be understood through scientific inquiry. </li></ul>
  23. 31. Dimensions Of Comte’s Positivism <ul><li>Methodological - the application of scientific knowledge to physical and social phenomena. </li></ul><ul><li>Social and political - the use of such knowledge to predict the likely results of different policies so the best one could be chosen. </li></ul>
  24. 32. Theory <ul><li>A set of logically interrelated statements that attempt to describe, explain and predict outcomes. </li></ul>
  25. 33. Levels of Sociological Analysis
  26. 34. Class lets begin to identify the various Sociological Theories <ul><li>There are 4 major sociological theories; </li></ul><ul><li>Please someone, identify the most conservative theory among the 4; </li></ul><ul><li>We will be talking about each of the theories, comparing and contrasting them in terms of the Marriage and Family Institution, what you indicated is the most popular of all the social institutions. </li></ul>

  34. 54. Sharpening Your Focus <ul><li>What is the relationship between theory and research? </li></ul><ul><li>What are the steps in the conventional research process? </li></ul><ul><li>What can qualitative methods add to our understanding of human behavior? </li></ul>
  35. 55. Theory and Research Cycle <ul><li>A theory is a set of logically interrelated statements that attempt to describe, explain, and predict social events. </li></ul><ul><li>Research is the process of systematically collecting information for the purpose of testing an existing theory or generating a new one. </li></ul><ul><li>The theory and research cycle consists of deductive and inductive approaches. </li></ul>
  36. 56. Conventional Research Model <ul><li>Select and define the research problem. </li></ul><ul><li>Review previous research. </li></ul><ul><li>Formulate the hypothesis. </li></ul><ul><li>Develop the research design. </li></ul><ul><li>Collect and analyze the data. </li></ul><ul><li>Draw conclusions and report the findings. </li></ul>
  37. 57. Theory and Research Cycle
  38. 60. Deductive Approach <ul><li>Theories generate hypotheses. </li></ul><ul><li>Hypotheses lead to observations. </li></ul><ul><li>Observations lead to the formation of generalizations. </li></ul><ul><li>Generalizations are used to support the theory, suggest modifications to it, or refute it. </li></ul>
  39. 61. Inductive Approach <ul><li>Specific observations suggest generalizations. </li></ul><ul><li>Generalizations produce a tentative theory. </li></ul><ul><li>The theory is tested through the formation of hypotheses. </li></ul><ul><li>Hypotheses may provide suggestions for additional observations. </li></ul>
  40. 62. Sociology and Scientific Evidence <ul><li>Many sociologists believe that two basic scientific standards must be met: </li></ul><ul><ul><li>Scientific beliefs should be supported by good evidence or information. </li></ul></ul><ul><ul><li>These beliefs should be open to public debate and critiques from other scholars, with alternative interpretations being considered. </li></ul></ul>
  41. 63. Sociology and Scientific Evidence <ul><li>Sociology involves debunking, unmasking false ideas or opinions. </li></ul><ul><li>Two approaches: </li></ul><ul><ul><li>Normative </li></ul></ul><ul><ul><li>Empirical </li></ul></ul>
  42. 64. Hypothesis Defined A predict statement derived from a theoretical perspective, that ascribes how two or more variables relate to each other.
  43. 65. Variables <ul><li>The independent variable is presumed to cause or determine a dependent variable. </li></ul><ul><li>The dependent variable is assumed to depend on or be caused by the independent variable(s). </li></ul>
  44. 66. Demonstrating Cause-and-Effect Relationships <ul><li>You must show that a correlation exists between the variables. </li></ul><ul><li>You must ensure that the independent variable preceded the dependent variable. </li></ul><ul><li>You must make sure that any change in the dependent variable was not due to a variable outside the stated hypothesis. </li></ul>
  45. 67. Cause and Effect Relationships <ul><li>Why do older African American men have a lower rate of suicide than older white males? </li></ul><ul><li>Questions like this are the foundation for study as sociologists try to understand cause-and-effect relationships. </li></ul>
  46. 68. Variables <ul><li>Independent </li></ul><ul><li>Dependent </li></ul><ul><li>Intervening </li></ul>
  47. 69. Hypothesized Relationships Between Variables <ul><li>Causal Relationship </li></ul>

Question <ul><li>In a medical study, lung cancer could be the _____ variable, while smoking could be the ______ variable. </li></ul><ul><ul><ul><li>dependant, independent </li></ul></ul></ul><ul><ul><ul><li>independent, dependant </li></ul></ul></ul><ul><ul><ul><li>valid, reliable </li></ul></ul></ul><ul><ul><ul><li>reliable, valid </li></ul></ul></ul>
  51. 73. Answer: a <ul><li>In a medical study, lung cancer could be the dependant variable, while smoking could be the independent variable. </li></ul>
  52. 74. Operational Definition <ul><li>An explanation of an abstract concept in terms of observable features that are specific enough to measure the variable. </li></ul><ul><li>The operational definition of an A may be an exam average of 90% or above. </li></ul>
  53. 75. Question <ul><li>Validity is the extent to which a study or research instrument: </li></ul><ul><ul><li>accurately measures what it is supposed to measure. </li></ul></ul><ul><ul><li>yields consistent results. </li></ul></ul><ul><ul><li>approximates a true experiment. </li></ul></ul><ul><ul><li>relies on other variables to preserve validity. </li></ul></ul>
  54. 76. Answer: A <ul><li>Validity is the extent to which a study or research instrument accurately measures what it is supposed to measure. </li></ul>
  55. 77. Validity <ul><li>The extent to which a study or research instrument accurately measures what it is supposed to measure. </li></ul>
  56. 78. Reliability <ul><li>The extent to which a study or research instrument yields consistent results when applied to different individuals at one time or to the same individuals over time. </li></ul>
  57. 79. Sharpening Your Focus <ul><li>Why is it important to have a variety of research methods available? </li></ul><ul><li>Why is a code of ethics for sociological research necessary? </li></ul>
  58. 80. Triangulation <ul><li>Combining multiple methods in a given study. </li></ul><ul><li>Triangulation refers not only to research methods but also to multiple data sources, investigators, and theoretical perspectives in a study. </li></ul><ul><li>Multiple data sources include persons, situations, contexts, and time. </li></ul>
  59. 81. ASA Code of Ethics <ul><li>Disclose research findings in full and include all possible interpretations of the data. </li></ul><ul><li>Safeguard the participants’ right to privacy and dignity while protecting them from harm. </li></ul>
  60. 82. ASA Code of Ethics <ul><li>Protect confidential information provided by participants. </li></ul><ul><li>Acknowledge research collaboration and disclose all financial support. </li></ul>
  61. 83. Sampling <ul><li>In random sampling , every member of an entire population being studied has the same chance of being selected. </li></ul><ul><li>In probability sampling , participants are deliberately chosen because they have specific characteristics, possibly including such factors as age, sex, race/ethnicity, and educational attainment. </li></ul>
  62. 84. Research and Social Factors <ul><li>Sociological research looks at factors that motivate suicide bombers. </li></ul><ul><li>Some researchers might ask why suicide bomber Raed Abdel-Hameed Mesk would take his own life while committing a terrorist attack. </li></ul>
  63. 85. Research Methods <ul><li>Specific strategies or techniques for systematically conducting research. </li></ul>
  64. 86. Qualitative Research Method <ul><li>Researcher begins with a general approach rather than a highly detailed plan. </li></ul><ul><li>Researcher has to decide when the literature review and theory application should take place. </li></ul>
  65. 87. Qualitative Research Method <ul><li>The study presents a detailed view of the topic. </li></ul><ul><li>Access to people or other resources that can provide necessary data is crucial. </li></ul><ul><li>Appropriate research method(s) are important for acquiring useful qualitative data . </li></ul>
  66. 88. Survey Research <ul><li>Describes a population without interviewing each individual. </li></ul><ul><li>Standardized questions force respondents into categories. </li></ul><ul><li>Relies on self-reported information, and some people may not be truthful. </li></ul>
  67. 89. Survey Definitions <ul><li>Respondents are persons who provide data for analysis through interviews or questionnaires. </li></ul><ul><li>A questionnaire is a printed research instrument containing a series of items to which subjects respond. </li></ul><ul><li>An interview is a research method in which an interviewer asks the respondent questions and records the answers. </li></ul>
  68. 90. Surveys and Polls <ul><li>Conducting surveys and polls is an important means of gathering data from respondents. </li></ul>
  69. 91. Computer-assisted Telephone Interviewing <ul><li>The widespread use of answering machines, voice mail, and caller ID may make this form of research more difficult in the twenty-first century. </li></ul>
  70. 92. Research Methods: Field Research <ul><li>Study of social life in its natural setting. </li></ul><ul><li>Observing and interviewing people where they live, work, and play. </li></ul><ul><li>Generates observations that are best described verbally rather than numerically. </li></ul>
  71. 93. Field Research <ul><li>How might sociologists study the ways in which parents and their college-age children cope when the students first leave home. </li></ul>
  72. 94. Approaches to Field Research <ul><li>Participant observation </li></ul><ul><ul><li>Collecting observations while part of the activities of the group being studied. </li></ul></ul><ul><li>Ethnography </li></ul><ul><ul><li>Detailed study of the life and activities of a group of people over a period of years. </li></ul></ul>
  73. 95. Approaches to Field Research <ul><li>Case Studies - In-depth, multifaceted investigation of a single event, person, or social grouping. </li></ul><ul><ul><li>A collective case study involves multiple cases. </li></ul></ul><ul><li>An unstructured interview is an extended, open-ended interaction between an interviewer and an interviewee. </li></ul>
  74. 96. Ethnographic Research <ul><li>Sociologist Elijah Anderson’s 14 year study of two Philadelphia neighborhoods— one populated by low-income African Americans, the other racially mixed but increasingly middle- to upper income and white—is an example of ethnographic research. </li></ul>
  75. 97. Research Methods: Secondary Analysis of Existing Data <ul><li>Materials studied may include: </li></ul><ul><ul><li>books, diaries, poems, graffiti, movies, television shows, advertisements, greeting cards, music, art, and even garbage. </li></ul></ul>
  76. 98. Experiments <ul><li>Study the impact of certain variables on subjects’ attitudes or behavior. </li></ul><ul><li>Designed to create “real-life” situations. </li></ul><ul><li>Used to demonstrate a cause-and-effect relationship between variables. </li></ul>
  77. 99. Non Laboratory Settings <ul><li>Natural experiments may be conducted when an unforeseen event occurs. What adaptation strategies did these people use during the massive power outage in the northeastern United States? </li></ul>
  78. 100. Effective Research Methods <ul><li>Which methods might be most effective in learning about the problems of the homeless, such as these street people warming themselves on a warm grate in Moscow, Russia? </li></ul>
  79. 101. Strengths and Weaknesses of Research Methods Research Method Strengths Weaknesses Experiments (Laboratory, Field, Natural) Control over research. Ability to isolate experimental factors. Little time and money required. Replication possible, except for natural experiments. Artificial Reliance on volunteers or captive audiences. Ethical questions of deception.
  80. 102. Statistics: What We Do and Don’t Know Homelessness in the U.S. Suicide in the U. S. Explanation The homeless often avoid interviews with census takers. Critics assert the actual number may be 3 million and that the government intentionally undercounts them. Census data places Latino/as in the category of whites. Other than African Americans, people of color are listed as nonwhite—other .
  81. 103. Strengths and Weaknesses of Research Methods Research Method Strengths Weaknesses Survey Research (Questionnaire, Interview, Telephone Survey) Useful in describing features of a large population without interviewing everyone Relatively large samples possible Multivariate analysis possible Potentially forced answers Respondent untruthfulness on emotional issues Data that are not always “hard facts” presented as such in statistical analyses
  82. 104. Strengths and Weaknesses of Research Methods Research Method Strengths Weaknesses Secondary Analysis of Existing Data (Existing Statistics, Content Analysis) Data readily available. inexpensive to collect. Longitudinal and comparative studies possible. Replication possible. Difficult to determine accuracy of data. Failure of data gathered by others to meet goals of current research. Questions of privacy when using diaries, other personal documents.
  83. 105. Strengths and Weaknesses of Research Methods Research Method Strengths Weaknesses Field Research (Participant Observation, Case Study, Ethnography, Unstructured Interview) Gain insider’s view. Useful for studying behaviors in natural settings. Longitudinal studies possible. Documentation of social problems of groups possible. Problems generalizing results. Non-precise data measurements. Inability to test theories. Difficult to make comparisons. Not representative.
  84. 106. Quantitative and Qualitative Research <ul><li>Quantitative research focuses on data that can be measured numerically. </li></ul><ul><li>Qualitative research focuses on interpretive description rather than statistics to analyze underlying meanings and patterns of social relationships. </li></ul>
  85. 107. Analyzing Content <ul><li>Examination of cultural artifacts or forms of communication to draw conclusions about social life. </li></ul><ul><li>Cultural artifacts are products of individual activity, social organizations, technology, and cultural patterns. </li></ul><ul><li>Among the materials studied are diaries, love letters, poems, books, and graffiti, movies, television, advertisements, and greeting cards. </li></ul>
  86. 108. Correlation Versus Causation <ul><li>A study might find that exposure to a suicide hot line is associated with a change in attitude toward suicide. </li></ul><ul><li>If some of the students who were exposed to the hot line also received psychiatric counseling, the counseling may be the “hidden” cause of the observed change in attitude. </li></ul><ul><li>Correlations alone do not prove causation. </li></ul>
  87. 109. Hawthorne Effect <ul><li>A phenomenon in which changes in a subject’s behavior are caused by the researcher’s presence or by the subject’s awareness of being studied. </li></ul>
  88. 110. Understanding Statistical Data Presentations <ul><li>Read the title. </li></ul><ul><li>Check the source and explanatory notes. </li></ul><ul><li>Read the headings for each column and row. </li></ul><ul><li>Examine and compare the data. </li></ul><ul><li>Draw conclusions. </li></ul>
  89. 111. Statistics: What We Do and Don’t Know Homelessness in the U.S. Suicide in the U. S. Research Finding At least 250,000 people in the U.S. are homeless. At least 32,439 Americans committed suicide in 2004. Possible Problem Does that underestimate the number of homeless people? Are suicide rates different for some categories of U.S. citizens?
  90. 112. U.S. Suicides, by Sex and Method Used, 1984 and 2004 Method Males Females 1984 2000 1984 2000 Total 22,689 25,566 6,597 6,873 Firearm 14,504 14,523 2,609 2,227 Poisoning 3,203 3,200 2,406 2,600 Suffocation 3,478 5,980 863 1,356
  91. 113. Grounded Theory <ul><li>Researchers who use grounded theory collect and analyze data simultaneously. </li></ul><ul><ul><li>For example, after in-depth interviews with 106 suicide attempters, researchers in one study concluded that half of the individuals who attempted suicide wanted both to live and to die at the time of their attempt. </li></ul></ul>
  92. 114. Zellner Research <ul><li>Sociologist William Zellner wondered if some automobile “accidents” were actually suicides. </li></ul><ul><li>By interviewing people who knew the victims, Zellner hoped to obtain information that would help determine if the deaths were accidental or intentional. </li></ul>
  93. 115. Zellner Research <ul><li>When he recruited respondents, he suggested their participation might reduce the number of accidents in the future; but didn’t mention that he suspected autocide. </li></ul><ul><li>From the data he collected, Zellner concluded that at least 12% of the fatal single-occupant crashes were suicides. </li></ul>
