Evaluation of the Happiness Through Goal-Setting Training.

This paper describes the evaluation of the Happiness through Goal-Setting Training, a multiple intervention approach which helps participants to reflect on, and modify their reasons for goal pursuit. The training is theoretically grounded in the goal-striving reasons framework. This framework captures four important reasons for goal pursuit and has received a substantial amount of empirical support for its predictive power in relation to positive psychological functioning. The four goal-striving reasons are the pursuit of goals out of pleasure, altruism, fear of self-esteem loss or necessity. The evaluation of the training, employing a before-and-after study design, is based on two data sets comprising data from a face-to-face delivery of the training (N = 41) and an online delivery of the training (N = 40). Overall, the findings from both studies, using paired sample t-tests, show that the Happiness through Goal-Setting Training significantly improves the quality of people's reasons for goal pursuit as well as their positive psychological functioning measured through life satisfaction, positive affect, negative affect and work-engagement. Thus, the Happiness through Goal-Setting Training complements the existing suite of well-being interventions by providing a happiness training that focusses specifically on improving people's reasons for goal-pursuit.

Comparative omasum anatomy in ruminants: Relationships with natural diet, digestive physiology, and general considerations on allometric investigations.

The omasum is the third forestomach compartment of pecoran ruminants. It is assumed that the re-absorption of fluid present in the forestomach digesta (that facilitates particle sorting, digestion, and harvest of microbes) is its main function, so that less diluted digesta is submitted to enzymatic digestion in the lower digestive tract. Here, we evaluate measures of omasum size (representing 84 ruminant species in the largest data set) against body mass and proxies of the natural diet (%grass) or forestomach physiology (fluid throughput), using phylogenetically controlled models. The origin of specimens (free-ranging or captive) did not have an effect in the data set. Models with the best support invariably either included %grass or a physiology proxy in addition to body mass. These effects were not necessarily additive (affecting the intercept of the allometric regression), but often indicated a change in the allometric body mass-exponent with diet or physiology. Only models that allowed an influence on the allometric exponent yielded basic exponents compatible with predictions derived from geometry. Species that include more grass in their natural diet, or that have a "cattle-type" physiology marked by a high forestomach fluid throughput, generally have larger omasa. However, the existence of outliers, as well as the overall data pattern, suggest that this is not an obligatory morphophysiological condition. Circumstantial evidence is presented leading to the hypothesis that the comparatively small and less complex omasa of "moose-type" species do not necessarily represent an "original" state, but may be derived from more complex states by ontogenetic reduction and fusion of omasal laminae.
