Prediction of university students' academic achievement by linear and logistic models

University students' academic achievement measured by means of academic progress is modeled through linear and logistic regression, employing prior achievement and demographic factors as predictors. The main aim of the present paper is to compare results yielded by both statistical procedures, in order to identify the most suitable approach in terms of goodness of fit and predictive power. Grades awarded in basic scientific courses and demographic variables were entered into the models at the first step. Two hypotheses are proposed: (a) Grades in basic courses as well as demographic factors are directly related to academic progress, and (b) Logistic regression is more appropriate than linear regression due to its higher predictive power. Results partially confirm the first prediction, as grades are positively related to progress. However, not all demographic factors considered proved to be good predictors. With regard to the second hypothesis, logistic regression was shown to be a better approach than linear regression, yielding more stable estimates with regard to the presence of ill-fitting patterns.     

Is Optimism Always Best?: Future Outlooks and Preparedness

ABSTRACT— Although people generally appear optimistic about the future, they shift from optimism under certain circumstances. Drawing from a recent review of the literature, we describe how both optimism and shifts from optimism serve the common goal of preparedness, which includes a readiness to deal with setbacks and a readiness to take advantage of opportunities. Shifts from optimism occur in response to available information and to the possibility that things may not turn out as hoped. People tend to shift from optimism when feedback is anticipated in the near future, when the outcome is important, when negative outcomes are easily imagined, and when the outcomes are uncontrollable. In addition, people with low self-esteem shift from optimism more readily than do people with high self-esteem. Finally, both optimism and shifts from optimism have unique benefits in terms of preparedness.     

The Spacing Effect: Enhancing Memory for Repeated Marketing Stimuli

We explore the extent to which repeating a brand‐attribute association will have a greater effect on recall when the 2 repetitions occur at different points in time rather than immediately after each other. Cued recall is generally better when the repeated items are separated. However, this depends on the extent to which information is organized by brand as well as by attribute, the number of attribute items presented about the brand, and the relatedness of the attributes.     

Emotion and rationality: The characterisation and evaluation of opposition to renewable energy projects

Opposition to wind farm developments has been seen as a significant threat to climate change mitigation policies in the UK. This paper considers the complex of different factors that may lie behind such oppositional activism and the role of emotion within these. Drawing on a programme of interviews it then explores in detail the ways in which industry and policy actors construct the role of emotion in wind farm opposition and in decisions on planning permission, often as an unwelcome intrusion into a supposedly rational process. The consequences of such understandings of opposition for the shaping of public engagement practices and for the nature and quality of public debate are examined.     

The relative importance of needs among traumatized and non-traumatized samples

Typically, people rate enhancement needs as more important than security needs to their well-being. Two studies tested whether event valence and prior trauma moderate relative need importance. Traumatized (hurricane survivors) and non-traumatized (control) participants recalled the most “distressing” (security-relevant) or “satisfying” (enhancement-relevant) event they had recently experienced and rated the importance of 10 needs in defining the event. In both studies, event valence moderated relative need importance on explicit (salience) and implicit (affect) measures as enhancement needs were more important for enhancement-relevant (satisfying) events whereas security needs were more important for security-relevant (distressing) events. However, results also suggest that differences in traumatic experience across samples moderated the effect of event valence on relative need importance. Unlike non-traumatized (control) participants, traumatized (hurricane survivors) participants did not reassign greater importance to enhancement over security needs when event valence shifted to enhancement-relevant (satisfying) memories. We close by discussing implications for human motivation.     

Work Stress and Marriage: A Theoretical Model Examining the Relationship Between Workaholism and Marital Cohesion

Using structural equation modeling the relationship of work stress and marital cohesion was empirically investigated. It was hypothesized that work stress would have an inverse relationship with marital cohesion. Participants were a random sample of 326 adult females who were members of the American Counseling Association. The results of the data-model fit analyses support the hypothesized relationship. The coefficient of determination for the structural equation was 0.60 indicating a substantial degree of explanation for the relationship tested. Implications of these findings for future research are presented.     

Translation and validation of the Spanish version of the RELATE questionnaire using a modified serial approach for cross-cultural translation.

This article describes the initial translation and validation of the Spanish version of the RELATionshhip Evaluation (RELATE) questionnaire with a sample of monolingual English speakers (n = 78), a sample of monolingual Spanish speakers (n = 18), and two samples of Spanish/English Bilinguals (n = 27 and n = 34). Cross-cultural and cross-language equivalence of the Spanish version of RELATE to the original English version were assessed using a Modified Serial Approach (MSA) for instrument translation. Face and content validity of the Spanish RELATE were established. Test-retest reliability indices obtained with the translated version among the monolingual and bilingual Spanish speaking groups were consistently equivalent to, and in some cases higher than, the baseline reliability obtained with the monolingual English speaking group. Applications of the Spanish version of RELATE and use of the MSA for researchers and practitioners are presented.
