Owing to intensive development of the theory of self-organization of complex systems called also synergetics, profound changes in our notions of time occur. Whereas at the beginning of the 20th century, natural sciences, by picking up the general spirit of Einstein's theory of relativity, consider a geometrization as an ideal, i.e. try to represent time and force interactions through space and the changes of its properties, nowadays, at the beginning of the 21st century, time turns to be in the focus of attention. It turns to be possible to represent space through time, because synergetics shows that historical and evolutionary stages of development of a complex structure can be found now, in its present spatial configuration. A whole series of paradoxical notions, such as “the influence of the future upon the present”, a “possibility of touching of a rather remote future today”, “availability of the past and the future now, in praesenti”, “irreversibility and elements of reversibility in the course of evolutionary processes in time”, “discrete unites, quanta of time”, appear in synergetics. 相似文献

Research on the additive interspersal procedure was extended by exposing seventh-grade students to curricula-based (e.g.,
educationally valid) language arts assignments. In Experiment I, each student was given a control language arts assignment
containing 20 discrete target items and an experimental assignment containing 24 equivalent target items, plus eight interspersed
briefer items. After working on both assignments for 10 minutes, significantly more students chose a new experimental assignment
for homework. Individual analysis showed that 85% of the students preferred or chose the assignment associated with higher
discrete task completion rates. In Experiment II, students completed both assignments. Results extended previous research
by showing that even after expending more effort to complete the 20% more target items plus the additional interspersed items
on the experimental assignments, significantly more students chose an experimental assignment for homework. Applied and theoretical
implications are discussed along with limitations of the current study and directions for future research. 相似文献

Researchers and practitioners have questioned how the implementation of a system of care influences the broader context of
children's social services within a community. We examined the impact that the Dawn Project system of care had on children's
services in Marion County, Indiana. A series of semi-structured interviews were conducted in order to gain a broad understanding
of stakeholder perspectives related to how system-level and other community leaders viewed system of care influences. Qualitative
analyses uncovered several common themes including positive impact at the community level, challenges to implementation, and
feelings of ambivalence related to program impact. Results were generally positive and suggested that most respondents saw
core system of care principles beginning to emerge within the community related to the establishment of the care system. In
addition, challenges to implementing the system of care also were uncovered, including some underlying resistance to system-level
changes. Implications from our study highlight the importance of continuously working to enhance strengths and collaboration
among systems, integrate and coordinate across systems and services, and authentically involve families at all levels. 相似文献

Millers Living Systems Theory (LST) is known to be very comprehensive. It comprises eight nested hierarchical levels. It also includes twenty critical subsystems. While Millers approach has been analyzed and applied in great detail, some problematic features remain, requiring further explication. One of these is the relationship between reduction and emergence in LST. There are at least four relevant possibilities. One is that LST exhibits neither clear reductionism nor emergence, but is essentially neutral in this regard. Another is that the apparent comprehensiveness of LST is illusory, as the approach remains vulnerable to reduction that could ultimately reduce it to a shadow of its present self. The charge of reductionism has been made by critics leading Miller to defend this theory vehemently as nonreductionist in nature. A third possibility is that LST is not reductionist, but is in fact an emergent theory. Miller makes this claim quite strongly. A fourth possibility, and in some ways the most analytically problematic, is that LST exhibits evidence of both reductionism and emergence simultaneously. Some critics might see this fourth situation as evidence of a troubling paradox or anomaly that must be resolved before further progress can be made in the explication and application of LST. The purpose of the paper is to remove this apparent anomaly. The paper removes this anomaly by differentiating between new-variable emergence and transformational emergence. No concrete evidence is found to contradict Milers claim of emergence in LST, and thus no true anomaly exists. 相似文献

We conducted a close replication of the seminal work by Marcus and colleagues from 1999, which showed that after a brief auditory exposure phase, 7-month-old infants were able to learn and generalize a rule to novel syllables not previously present in the exposure phase. This work became the foundation for the theoretical framework by which we assume that infants are able to learn abstract representations and generalize linguistic rules. While some extensions on the original work have shown evidence of rule learning, the outcomes are mixed, and an exact replication of Marcus et al.'s study has thus far not been reported. A recent meta-analysis by Rabagliati and colleagues brings to light that the rule-learning effect depends on stimulus type (e.g., meaningfulness, speech vs. nonspeech) and is not as robust as often assumed. In light of the theoretical importance of the issue at stake, it is appropriate and necessary to assess the replicability and robustness of Marcus et al.'s findings. Here we have undertaken a replication across four labs with a large sample of 7-month-old infants (N = 96), using the same exposure patterns (ABA and ABB), methodology (Headturn Preference Paradigm), and original stimuli. As in the original study, we tested the hypothesis that infants are able to learn abstract “algebraic” rules and apply them to novel input. Our results did not replicate the original findings: infants showed no difference in looking time between test patterns consistent or inconsistent with the familiarization pattern they were exposed to. 相似文献

A converging body of evidence from neuroimaging, behavioral, and neuropsychology studies suggests that different arithmetic operations rely on distinct neuro-cognitive processes: while addition and subtraction may rely more on visuospatial reasoning, multiplication would depend more on verbal abilities. In this paper, we tested this hypothesis in a longitudinal study measuring language and visuospatial skills in 358 preschoolers, and testing their mental calculation skills at the beginning of middle school. Language skills at 5.5 years significantly predicted multiplication, but not addition nor subtraction scores at 11.5 years. Conversely, early visuospatial skills predicted addition and subtraction, but not multiplication scores. These results provide strong support for the existence of a double dissociation in mental arithmetic operations, and demonstrate the existence of long-lasting links between language/visuospatial skills and specific calculation abilities. 相似文献

Literature suggests that motor skills are associated with other areas of development or domains, such as language and math, especially at early ages. These results are mainly based on studies developed in medium-to-high sociocultural contexts. Thus, this study was conducted in a medium-to-low-income area. The aim was to know the 4–5 years old children's motor development (both fine and gross motor skills), and its relation to language and mathematical development. A total of 219 Colombian Caribbean children (105 boys and 114 girls) aged 4 and 5 years participated in this study. Results revealed higher motor skills among girls, although differences by gender were not notable. Positive and significant correlations were found between motor skills and language and mathematical skills, although most of the correlations were weak or moderate. Also, it was observed that fine motor skills were less related to language or mathematical development in comparison with gross motor skills, especially among boys. These results suggest that among Colombian Caribbean children gross motor skills could have a higher influence on the development and acquisition of some language and mathematical skills in comparison with fine motor skills. 相似文献

This study explored the language experiences of dual language learners (DLL; n = 19) and English monolinguals (EM; n = 13) in preschool classrooms where English is the primary language of instruction and many home languages are present. Using the Language ENvironment Analysis™ system as a primary tool, we quantitatively analysed an average of 34 hours of recordings collected over 5–8 days for each participating child (Mage = 52 months) in six classrooms. Results showed that, during a typical preschool day, DLLs spoke as much as EMs but received less adult talk overall and had more 5-min segments with zero adult–child conversations than their EM peers. Follow-up analyses revealed that teachers generally talked less when children initiated the conversations than when adults initiated the conversations, and this pattern was particularly evident for DLLs. Study implications and future research are discussed. 相似文献

Controversy exists as to whether, compared to young adults, older adults are more, equally or less likely to make linguistic predictions while reading. While previous studies have examined age effects on the prediction of upcoming words, the prediction of upcoming syntactic structures has been largely unexplored. We compared the benefit that young and older readers gain when the syntactic structure is made predictable, as well as potential age differences in the costs involved in making predictions. In a self-paced reading study, 60 young and 60 older adults read sentences in which noun-phrase coordination (e.g. large pizza or tasty calzone) is made predictable through the inclusion of the word either earlier in the sentence. Results showed a benefit of the presence of either in the second half of the coordination phrase, and a cost of the presence of either in the first half. We observed no age differences in the benefit or costs of making these predictions; Bayes factor analyses offered strong evidence that these effects are age invariant. Together, these findings suggest that both older and younger adults make similar strength syntactic predictions with a similar level of difficulty. We relate this age invariance in syntactic prediction to specific aspects of the ageing process. 相似文献
