The impact of self-efficacy on behavior change and weight change among overweight participants in a weight loss trial.

Despite considerable clinical interest, attempts to link perceived self-efficacy with successful weight control have had mixed success. Definitive data on prospective associations between self-efficacy and weight loss are particularly sparse. This study examined relationships between self-efficacy beliefs, weight control behaviors, and weight change among individuals participating in a weight loss trial (N = 349, 87% women). Cross-sectionally, eating and exercise self-efficacy beliefs were strongly associated with corresponding weight loss behaviors. Self-efficacy beliefs prospectively predicted weight control behavior and weight change during active treatment but not during follow-up. Mediational models indicate that people's weight control behaviors mediate the impact of self-efficacy on weight change.     

Anticipating Alternative National and Regional Futures in Energy Efficiency

Thirty-five stakeholder representatives and six observers from thirty organizations, interested in anticipating the adoption of energy efficiency for the Pacific Northwest, identified and described one hundred and seventy-eight national and regional trends extending to the year 2015 impacting energy efficiency, and proposed more than ninety actions for addressing these trends at the regional level. The representatives were engaged in a collaborative action planning workshop that was facilitated with the CogniScope methodology founded in the systems sciences. Convergence was achieved on eight highly influential actions as the highest priority.     

Viewpoint-dependent recognition of scenes

Three experiments investigated scene recognition across viewpoint changes, involving same/different judgements on scenes consisting of three objects on a desktop. On same trials, the comparison scene appeared either from the same viewpoint as the standard scene or from a different viewpoint with the desktop rotated about one or more axes. Different trials were created either by interchanging the locations of two or three of the objects (location change condition), or by rotating either one or all three of the objects around their vertical axes (orientation change condition). Response times and errors increased as a function of the angular distance between the standard and comparison views, but this effect was bigger for rotations around the vertical axis than for those about the line of sight or horizontal axis. Furthermore, the time to detect location changes was less than that to detect orientation changes, and this difference increased with increasing angular disparity between the standard and comparison scenes. Rotation times estimated in a double-axis rotation were no longer than other rotations in depth, indicating that alignment was not necessarily simpler around a "natural" axis of rotation. These results are consistent with the hypothesis that scenes, like many objects, may be represented in a viewpoint dependent manner and recognized by aligning standard and comparison views, but that the alignment of scenes is not a holistic process.     

Relativism,Disagreement and Testimony

This article brings together two sets of data that are rarely discussed in concert; namely, disagreement and testimony data. I will argue that relativism yields a much more elegant account of these data than its major rival, contextualism. The basic idea will be that contextualists can account for disagreement data only by adopting principles that preclude a simple account of testimony data. I will conclude that, other things being equal, we should prefer relativism to contextualism. In making this comparative point, I will also defend self‐standing relativist accounts of disagreement and testimony data.     

A metarepresentational theory of intentional identity

Synthese - Geach points out that some pairs of beliefs have a common focus despite there being, apparently, no object at that focus. For example, two or more beliefs can be directed at Vulcan even...     

When planning is needed: Implementation intentions and attainment of approach versus avoidance health goals

OBJECTIVE: This study tested whether forming implementation intentions is an effective strategy for attaining health goals focused on trying to avoid a negative state. DESIGN: Participants chose to either eat more healthy snacks (i.e., an approach goal) or eat fewer unhealthy snacks (i.e., an avoidance goal) over two weeks and were randomly assigned to create an implementation intention to do this or not. MAIN OUTCOME MEASURES: The authors measured fat and calorie intake after one week and after two weeks. RESULTS: After two weeks, the participants who ate most unhealthily were those who pursued an avoidance goal and did not form an implementation intention. CONCLUSION: These results suggest that forming implementation intentions for avoidance goal pursuit can help people attain important health goals.
