刘建军 《思想理论教育导刊》2006,(10):62-64
共产主义理想及其追求有着丰富的内涵,应该用辩证的观点来全面把握。对共产主义的追求是理想与信念的统一,共产主义理想是社会政治理想与个人道德理想的统一,对共产主义理想的追求是目标与过程的统一,共产主义理想是终极性与非终极性的统一。 相似文献

Many theories on college retention recognize the significance of student satisfaction as a positive factor in students’ persistence.
Yet, there are few theories that address the relationship of degree program satisfaction to study behaviour and dropout. This
paper explores the impact of degree program satisfaction on academic accomplishment and dropout. The impact of degree program
satisfaction was studied within a multitheoretical framework. The results of the study show that student accomplishment not
only depends on differences in academic ability but also on degree program satisfaction. Decreased degree program satisfaction
appears to diminish both study motivation and study behaviour. The authors discuss some implications for current educational
practice. 相似文献

Weanling rats were tested for retention of an aversion to a novel flavor (chocolate milk) that had been conditioned as a single-element conditioned stimulus (CS) or in compound with a novel ambient odor (banana). The presence of the ambient odor during conditioning had no effect on flavor aversion shortly thereafter, confirming previous results. The flavor aversion observed 21 days after conditioning, however, was significantly stronger for pups conditioned with the single-element CS than for those given the flavor-odor compound as the CS. This retention effect was due to a surprisingincrease in the conditioned aversion observed 21 days after conditioning with the single-element CS. A second experiment confirmed this paradoxical increase in retention of the aversion to chocolate milk. This experiment also verified that no such increase occurred in retention of the conditioned aversion to a different flavor (saccharin), whether the initial aversion was strong or weak. The results may be explained in terms of generalized latent inhibition from consumption of mother’s milk. 相似文献

A dance programme for a class of students with special needs was evaluated using a multiple baseline across behaviours design where the behaviours were movements representing aspects of the elements of dance: Space, Body Awareness, Relationships, Levels, Effort, Speed and Shape. Observational data showed that the instructional dance programme was successful in extending the variety of movements performed by the students and that the observational methodology designed for the study was a useful strategy for evaluating teaching in dance. 相似文献

To obtain confirmation of the findings of the authors' earlier comparison of ever-pregnant and nonpregnant Black high school students from Tennessee, 16 students confirmed to be pregnant were substituted for the 33 subjects in the original study whose pregnancy status was based solely on self-report. The nonpregnant control group of 251 teens was utilized in both analyses. Although the confirmed pregnant group was too small to repeat the regression analysis, striking concordance of findings between the 2 studies emerged for all dependent variables except the Eysenck Personality Questionnaire anxiety scale. The lower anxiety scores recorded among subjects in the original study may be either a statistical artifact or a reflection of the fact that these pregnant teens remained in school while subjects in the second study were enrolled in programs centered around their pregnant status. Sexual activity scores were strong or moderate significantly more often in both groups of pregnant teens compared to their nonpregnant counterparts. Interesting was the finding that 81% of pregnant teens regarded romance novels and soap operas to be accurate portrayals of real-life dating relationships compared to only 49% of nonpregnant teens. On the other hand, only 56% of the pregnant subjects regarded their own relationships to have this romantic quality. In a future study, the role of such uncritical romantic ideals in adolescent pregnancy risk will be investigated in a larger sample. 相似文献
