Communicating Research Findings More Effectively: The Potential for Conflict Index

This presentation introduces the Potential for Conflict Index (PCI) and discusses enhancements in the 2nd generation of PCI. It provides a partial validation of PCI2 and demonstrates the PCI2 menu system. The goal is to effectively communicate research findings in a way that bears meaning on problems of managerial or scientific interest.

  1. Communicating Research Findings More Effectively: The Potential for Conflict Index Jerry J. Vaske Colorado State University Human Dimensions of Natural Resources Fort Collins, CO 80523

  2. Overview of Presentation • Introduce Potential for Conflict Index (PCI1) • Describe enhancements in 2nd generation of PCI2 • Provide a partial validation of PCI2 • Demonstrate the PCI2 menu system

  3. Goal – Challenge – Solution • Goal of Human Dimensions / Recreation research Conceptualize, measure and interpret variables and their relationships in a way that bears meaning on problems of managerial or scientific interest • Challenge Effectively communicating the meaning of abstract statistics (e.g., standard deviation, standard error)for measuring consensus • Solution – Potential for Conflict Index (PCI)Manfredo, Vaske, & Teel, 2003 Vaske et al., 2006; Vaske et al., 2010

  4. Potential for Conflict Index (PCI) • Integrates into one measure information about: • Central tendency • Dispersion • Shape of a distribution • Uses graphic display: Easy interpretation • Places findings in managerial context(e.g., the acceptability of a given mgmt. action)

  5. PCI1 Measurement Requirements Response scale • Balanced scale with equal number of response options on either side of “Neutral” point • Number of response options can be 3, 5, 7, or 9(typical to have 5 or 7 response options) • Numerical ratings must be assignedwith center point given value of 0

  6. PCI Assumptions • Greatest potential conflict (PCI = 1) occurs with bimodal distribution: • 50% rate mgmt. action as “Highly Unacceptable” • 50% rate mgmt. action as “Highly Acceptable” • 0% are “Neutral” • No conflict (PCI = 0) occurs when: • 100% rate mgmt. action in a single category(e.g., 100% “Highly Unacceptable” OR 100% “Highly Acceptable”) • Index range: 0 (no conflict – most consensus) to 1 (most conflict – least consensus)

  7. Previous Applications of PCI • Yellowstone wolf mgmt. (ID & WY) • Desert tortoise mgmt. (CA) • Chronic wasting disease (8 states) • Off leash dogs urban parks (CO) • Wildlife values (19 states) • Wildland fire management (3 states) • Instream flows in Hell’s Canyon (ID) • Scuba divers / snorkelers (FL) • Summer use – Whistler ski area (BC)

  9. Survey scenarios manipulated 3 species: Raccoons, Bears, Mountain Lions 3 levels – Severity ofhuman-wildlife interaction: Presence, Nuisance, Kills human Example scenario: A person encounters a black bear in their neighborhood. The bear charges and mauls the person, resulting in the person’s death. Given this scenario, how unacceptable or acceptable would it be for wildlife agencies to take each of the following actions.

  23. Enhancements in PCI2 • Generates statistic from SPSS, SAS, Excel & PHP • A simulation generates M & SD (default n = 400)(SD allows test of differences between PCI values) • Allows for: • different scale widths (2, 3, 4, 5, 6, 7, 8, 9) • unipolar & bipolar scales (with or without neutral value) • different power functions (i.e., 1, 2 or any power > 0) • different distance functions (D1, D2, D3)

  24. PCI2 – Distance Based Formula • Consider person (x) response relative to person (y) • Responses = rx and ry • Distance between people dx,y = f(rx, ry) • Different ways to define distance: dx,y = |rx – ry| • Issue: People at –3 & –2 not really in conflict; differ only in degree to which views are held • Alternative distance formulations ...

  25. PCI2 – Alternative Distance Functions D1 dx,y = (|rx – ry| – 1) If sign(rx) ≠ sign(ry); (e.g., rx = –3 & ry = +1) otherwise dx,y = 0 • Neutral is not considered in determining distance (D1: –3 to 1 is 3) D2 dx,y = |rx – ry| If sign(rx) ≠ sign(ry); otherwise dx,y = 0 • Neutral is considered in determining distance (D2: –3 to 1 is 4)

  26. PCI2 Formula where: nk = number of respondents for each scale value nh = number of respondents at other scale values dk,h = distances between respondents δmax = maximum distance between extreme values * number of times this distance occurs

  28. Current Recommended Settings: PCI2 • Distance: D1 • Power: P1: Power = 1 • Scale width: 5 or 7 points • Recommendations subject to further testing and validationusing actual & simulation data

  29. Toward a Validation of PCI2

  30. PCI2 – General Validation • Meets boundary conditions(i.e., PCI = 0 and / or 1 when it should) • Simulated values for a distribution are approximately normally distributed(i.e., usual tests for differences can be used) • Bias is small relative to standard deviation in a PCI estimated for a survey

  32. PCI – Conclusions • PCI offers an intuitive approach to summarizing statistical results • Based on past experiences, managers understand PCI results • Computing PCI & graphical displayis straightforward • PCI2 allows for multiple analytical options & experimentation capabilities

  33. PCI – Future Research • Continue validation • Further examination of scale width issues • Link PCI to practical significance indicators(e.g., effect sizes, Van der Eijk’s measure of agreement) • Apply PCI to more human dimensions issues • Develop standards for interpreting PCI values
