“…The internal consistency of behavioral measures and the LPP were evaluated through testing the correlation of the odd and even trials. The Spearman-Brown Prophecy Formula (Nunnally, Bernstein, & Berge, 1967) was used to correct these correlations because the total number of items included in the averages is split in half (reliability = 2 * r odd/even / 1 + r odd/even ). Spearman-Brown coefficients were evaluated where: > 0.80 = good/excellent, 0.70 – 0.79 = acceptable, and < 0.60 = poor.…”

Emotion processing in female youth: Testing the stability of the late positive potential

The Emotional Interrupt Task (EIT) has been used to probe emotion processing in healthy and clinical samples; however, research exploring the stability and reliability of behavioral measures and ERPs elicited from this task is limited. Establishing the psychometric properties of the EIT is critical, particularly as phenotypes and biological indicators may represent traitlike characteristics that underlie psychiatric illness. To address this gap, test-retest stability and internal consistency of behavioral indices and ERPs resulting from the EIT in healthy, female youth (n = 28) were examined. At baseline, participants were administered the EIT while high-density 128-channel EEG data were recorded to probe the late positive potential (LPP). One month later, participants were readministered the EIT. Four principal findings emerged. First, there is evidence of an interference effect at baseline, as participants showed a slower reaction time for unpleasant and pleasant images relative to neutral images, and test-retest of behavioral measures was relatively stable over time. Second, participants showed a potentiated LPP to unpleasant and pleasant images compared to neutral images, and these effects were stable over time. Moreover, in a test of the difference waves (unpleasant-neutral vs. pleasant-neutral), there was sustained positivity for unpleasant images. Third, behavioral measures and LPP demonstrated excellent internal consistency (odd/even correlations) across conditions. Fourth, highlighting important age-related differences in LPP activity, younger age was associated with larger LPP amplitudes across conditions. Overall, these findings suggest that the LPP following emotional images is a stable and reliable marker of emotion processing in healthy youth.

“…Reliability of each composite measure was determined by computing Cronbach's alpha (α). The lower bound for scale reliability is commonly indicated at 0.70 (see Nunnaly 1978). However, a lower threshold of 0.60 is frequently used throughout the literature (Morgan and Griego 1998).…”

ABSTRACT. Public participation is increasingly viewed as a means to initiate social learning among stakeholders, resource managers, and policy makers rather than to ensure democratic representation. This growing understanding of participatory activities as learning platforms can be seen as a direct response to shifts in how natural resources management is framed, namely as uncertain, non-linear, and interlinked with the human dimensions. Social learning as it is discussed within the natural resources management (NRM) context features a process of collective and communicative learning that is thought to enable stakeholders to arrive at a shared understanding of a specific environmental situation and to develop new solutions as well as ways of acting together in pursuit of a shared ambition. Yet, although case-study research on social-learning processes provides multiple accounts of positive experiences, there are also reports of mistaken learning, the intensification of tensions or conflict, and failure to reach agreement or verifiable consensus. Based on results of a postal survey of stakeholder experiences in two involvement initiatives, we can draw two main conclusions: First, social learning is a multidimensional and dynamic process and, as such, evolves in stages and to various degrees. Second, stakeholder processes are shaped and affected by a multitude of factors that constrain the occurrence of learning processes and eventually limit the extent to which these can contribute to sustainable NRM. Foremost, the fact that the intensity of stakeholder learning differed in the two investigated initiatives reinforces the role organizational arrangements play in encouraging the type of communicative process necessary for stakeholder learning.

Ethnic identification, acculturation and sports identification of Latinos in the United States

Sports management and marketing research has failed to study the dimensions of Latino sports consumption behaviour and fan identification. This research examined the relationships among ethnic identity, acculturation, identification with sport in general, and identification with specific sports for Latinos living in the United States. Even though the four models used fit the data well, in general, ethnic identity and acculturation had little or no influence on sports identification. Hence sports marketers should not create marketing campaigns solely based on the assumption that Latinos or any ethnic group are necessarily fans of any particular sport (e.g. soccer).
