This paper presents the systematic development of a 'Uses and Gratification Expectancy' (UGE) conceptual framework which is able to predict students' 'Perceived e-Learning Experience.' It is argued that students' UGE as regards e-learning resources cannot be implicitly or explicitly explored without first examining underlying communication theories and learning perspectives. As such, the theoretical framework is grounded in the confluence of theories from communication theories and learning perspectives. The integration of Expectancy-value Theory, and the Uses and Gratification Theory serves to accommodate the suggestion that elearning resources offer gratifications that are expected and valued by students. The key theoretical and practical assumptions of the UGE approach are highlighted and consistently implemented in the conceptual edifice.

“…In psychology, as well as in the visual assessment studies, the ordinal scale measures are traditionally used in the parametric statistical methods, even though they do violate the assumptions of the parametric methods. This tradition is based on the lack of appropriate non-parametric methods (Golbeck 1986). Some landscape researchers state that ordinal scale measures can be used for parametric statistical tests if the number of respondents is at least 20 and the group is homogenous (Daniel and Vining 1983), or if the preferences for the landscapes differ significantly (Benson and Ulrich 1981).…”

“…According to Golbeck (1986), no feasible method is available for deriving interval data from ordinal scale data. Further, it is difficult to say what the resulting estimates of scenic beauty really mean in the SBE-method (Golbeck 1986).…”

The visual preferences for forest regeneration and field afforestation - four case studies in Finland

The overall aim of this dissertation was to study the public's preferences for forest regeneration fellings and field afforestations, as well as to find out the relations of these preferences to landscape management instructions, to ecological healthiness, and to the contemporary theories for predicting landscape preferences. This dissertation includes four case studies in Finland, each based on the visualization of management options and surveys.Guidelines for improving the visual quality of forest regeneration and field afforestation are given based on the case studies. The results show that forest regeneration can be connected to positive images and memories when the regeneration area is small and some time has passed since the felling. Preferences may not depend only on the management alternative itself but also on the viewing distance, viewing point, and the scene in which the management options are implemented.The current Finnish forest landscape management guidelines as well as the ecological healthiness of the studied options are to a large extent compatible with the public's preferences. However, there are some discrepancies. For example, the landscape management instructions as well as ecological hypotheses suggest that the retention trees need to be left in groups, whereas people usually prefer individually located retention trees to those trees in groups. Information and psycho-evolutionary theories provide some possible explanations for people's preferences for forest regeneration and field afforestation, but the results cannot be consistently explained by these theories.The preferences of the different stakeholder groups were very similar. However, the preference ratings of the groups that make their living from forest -forest owners and forest professionals -slightly differed from those of the others. These results provide support for the assumptions that preferences are largely consistent at least within one nation, but that knowledge and a reference group may also influence preferences.

“…Because it is not possible to directly test for equality of intervals among an observer's ratings, some statisticians argue that ratings should not be used as if they represent interval data (e.g., Golbeck 1986). Others, however, argue, based on Monte Carlo simulations and other approaches, that there is little risk in applying parametric statistics to rating data, especially if ratings from a sufficient number of observers are being combined (Baker et al 1966, Gregoire and Driver 1987, O'Brien 1979.…”

Rating scales provide an efficient and widely used means of recording judgments. This paper reviews scaling issues within the context of a psychometric model of the rating process and describes several methods of scaling rating data. The scaling procedures include the simple mean, standardized values, scale values based on Thurstone's Law of Categorical Judgment, and regression-based values. The scaling methods are compared in terms of the assumptions they require about the rating process and the information they provide about the underlying psychological dimension being assessed.
