Programs to promote children's early development are based on a set of assumptions, explicit or implicit, about intended outcomes and how the program will effect change. The “theories of change” were examined in ten home-based programs in the Early Head Start Research and Evaluation Project (EHSREP), using data collected through multiple interviews with program staff. All home-based programs indicated that parenting outcomes were among their highest three priorities, while only 4 of 10 programs said that child outcomes were in their top priorities. The pattern of outcome differences between randomly-assigned program and control group participants reflected the programs’ theories of change in several ways. Early Head Start home-based programs showed positive impacts on 9 of 9 parenting outcomes, including parental supportiveness, home language and learning supports, emotional responsiveness, and family conflict when children were 24 months of age. Significant program impacts on child cognitive skills (Bayley MDI scores) and social behavior (observed child engagement of parent during play) were found when children were 36 months of age. Mediation analyses showed that the 54% of the program impact on 36-month child cognitive scores was mediated by 24-month program impacts on parental supportiveness, language and learning support, emotional responsiveness, and family conflict, and 47% of the program impact on 36-month child engagement of parent was mediated by 24-month impacts on parental supportiveness, language and cognitive stimulation, and emotional responsiveness. Results from mediation analyses were consistent with these home-based programs’ theories of change, supporting the efficacy of focusing on parent change as a mechanism for child outcomes in home visiting programs.  相似文献   

Physiological comparison of intensity-controlled,isocaloric intermittent and continuous exercise†

VO2 fluctuations are argued to be an important mechanism underpinning chronic adaptations following interval training. We compared the effect of exercise modality, continuous vs. intermittent realized at a same intensity, on electrical muscular activity, muscular oxygenation and on whole body oxygen uptake. Twelve participants (24?±?5 years; VO2peak: 43?±?6?mL·?min^?1·kg^?1) performed (i) an incremental test to exhaustion to determine peak work rate (WR_peak); two randomized isocaloric exercises at 70%WRpeak; (ii) 1 bout of 30 min; (iii) 30 bouts of 1?min work intercepted with 1?min passive recovery. For electromyography, only the CON exercise showed change for the vastus lateralis root-mean-square (+6.4?±?5.1%, P?P?vs. 2.32?±?1.21?mM, respectively, for the CON and INT, P?vs. 356?±?301?sec, respectively, for the CON and INT, P?相似文献

Procrastination—Not all it's put off to be     

Jeanne Farrington 《Performance Improvement Quarterly》2012,24(4):11-16

Although procrastination has devastating negative effects on performance, many of us employ common myth‐like justifications for it, thereby attempting to alleviate the guilt and stress that commonly accompany putting things off when we know we should not. Working better under pressure, being more creative at the last minute, and avoiding tasks because of perfectionism are three rationalizations that we often give for delay. The consequences of procrastination include missed deadlines, health and financial problems, guilt, stress, and work that isn't our best. To overcome a tendency to procrastinate, focusing on avoiding it is not the best response. Instead, adopting a task‐oriented, problem‐solving focus or set of strategies can work even for people with a long history of putting things off. These strategies include increasing the perceived value of a task, adjusting expectations for success, reducing impulsive temptations, and approaching larger projects or those with longer timelines in smaller segments with progress checks along the way. Procrastinators can learn how to change their approach to getting work done and thereby reduce their tendency to delay.  相似文献
