ABSTRACT This scholarly paper describes and analyzes the role of career and technical education (CTE) in Iowa community colleges. Iowa's community colleges are doing a good job of responding to the changing workforce needs of the state and providing smooth career pathways. However, changes in the population and economy of the state will call for further changes in CTE programs. The distinctive characteristics of CTE in Iowa community colleges, the impact of community college CTE programs on the state's economy, the role of accountability, and the future implications for CTE in the state are discussed. Recommendations based on the results of the study include improving articulation agreements, increasing retention among at-risk students, and increasing collaboration among Iowa's 15 community colleges. 相似文献

The old urban centres are marks of an historical and architectural heritage that should be protected and safeguarded. For such, it is fundamental to have a complete understanding of the genesis, regarding both building and the urban mesh. This fact is essential to the support of qualified, conscientious and sustainable rehabilitation interventions on the old building stock. The research carried out addresses the issue of the old urban centres from the perspective of the analysis and inventory of buildings features. The cataloguing process of the building typologies is presented in this work as a synthesis of the principal construction forms, with the old city centre of Seixal being used as a case study. The identification of building typologies has supported a seismic and fire vulnerability assessment of the old building stock. The assessment methodologies developed and used are based on the detailed survey and building inspection, therefore the building typology cataloguing is essential in the analysis at such a large scale. Then we discussed the strategy for the conservation actions incorporated in a broader risk management policy. 相似文献

This paper proves a general structural property of the wavelet tree for a given seminorm in the context of the wavelet packet transform method. This structural property can be used in denoising algorithms of different applications to guarantee the optimality of novel search strategies. The property holds for any input signals using any orthogonal analysing wavelet families. The property holds for any norms, which results to be a convex function through the wavelet tree. Using a defined norms, seminorms or pseudonorms, this property can be used to detect incoherent parts of an input signal by using the minimal depth of the tree. In this sense the proposed denoising procedure works without thresholds for the localisation of different kinds of noise, as well as for a stop criterium for an optimal representation of the incoherency. The proof of this property is performed by mathematical induction and the demonstration is based on orthonormality with the help of the multiresolution framework aspects of the wavelets packet tree. The Theorem is independent of the definition of the adopted norm and of the incoherent part of an input signal. In this sense, the discovered property is a general one, which is related to any norm and any nature of the signal incoherence. It can be used in different applications, in which a minimum of a norm is required to be calculated through the wavelet tree. 相似文献

Trajectories of stability and change in bullying roles were examined through a longitudinal prospective study of 916 school students followed up biannually from age 11 to 17. Perpetrators and victims had relatively stable trajectories with most of the children remaining in the same role over time or becoming uninvolved. Bully/victim was the most unstable role with frequent transitions to perpetrators or victims. Developmental change in bullying roles was found with a decrease in physical forms over time in bullies and victims but with persistently high perpetration and victimization in bully/victims. These findings open new horizons in research and practice related to bullying and can be useful for its early detection or design of targeted interventions. 相似文献

Previous research has suggested that children in the early grades of primary school do not have much awareness of morphemes.
In this study, a priming paradigm was used to try to detect early signs of morphological representation of stems through a
spelling task presented to Portuguese children (N = 805; age range 6–9 years). Primes shared the stem with the targets and contained well-articulated, stressed vowels; the
stems of the target words and pseudo-words contained non-stressed schwa vowels, which typically result in spelling difficulties.
If priming proved effective, the well-articulated vowels in the prime should result in an improvement in the spelling of the
schwa vowels. Primes were presented in two conditions: in only-oral or in oral-plus-written form. Effectiveness of priming
was assessed by comparison with a no-priming condition. For both words and pseudowords, there was a significant interaction
between priming effects and grade. No priming effects were detected in 6- and 7-year-old children; oral-plus-written priming
produced higher rates of correct vowel spelling for 8- and 9-year-olds; only-oral priming was effective in improving the vowel
spelling of 9-year-olds. Thus older children can use morphological information under priming conditions when the prime and
the target are not phonologically transparent but there is no evidence to suggest that younger children do so. 相似文献

The relationship between the construct of mental attention and “giftedness” is not well established. Gifted individuals could
make effective use of their executive functions and this could be related to their mental attentional capacity. The dialectic
constructivist model developed by Pascual-Leone introduced the concept of mental attention or “effort”, relating it to mental
capacity. The aim of this study is to investigate whether the measurement of mental capacity (M-measurement) is differential
for a group of children with high IQs. 110 students between 4 and 18 years old participated in this study. Some were Gifted
(n=70) and others Non-Gifted (n=40). Wechsler-R Scale and the Figural Intersection Test were administered to all participants.
An interesting pattern was found in the younger groups. The gifted scored higher than the non-gifted in the Figural Intersection
Test and much higher than their theoretical M. The non-gifted scored quite close to their theoretical M (based on age). In
the oldest group, the gifted again achieved higher scores, but now they scored at the theoretical level, and the non-gifted
underperformed. 相似文献

ABSTRACTNearly two decades have passed since the Open Educational Resources (OER) movement was launched. Its success in Brazil can be illustrated with the establishment of a UNESCO Chair in Open Education in 2014, in one of the country’s most prestigious universities. Crucially, OER were included in the 2014–2024 National Education Plan, a key piece of national educational legislation, as a category of educational technologies framed as tools. Assuming metaphors such as this play a key role in the ways we think, speak and act, this article presents a critical perspective on OER in Brazil. Examining the implications of the main metaphors used to construe OER in local media and academic sources, the text argues that these metaphors reflect hegemonic discourses on educational technology, concealing the non-neutrality of technological artefacts, obscuring issues concerning curriculum and pedagogy, and overlooking actual local needs. The article discusses issues concerning local OER advocacy, positioned in respect to specificities of a context where education, albeit a constitutionally established right, may be poised to undergo radical changes in the near future. 相似文献
