A Reflection on Curriculum Development with an emphasis on Eisner's View: An outdated or an up to date mission

Curriculum fields does not enjoy a stable professional identity. The uncertainty is rooted in the controversial nature of the missions surrounding the field. One controversy deals with the question of whether curriculum is part of the competencies expected from a curriculum specialists? or the historical evolution of the field has shed doubt on this supposedly clear function. The fact of the matter is that there no longer exists a consensus among curriculum scholars in this respect. The author has identified two contrasting views regarding this traditional mission which calls for further study and scruting. One group who totally reject this traditional mission are called reconceptualists. The second position is a more complex and intricate one which has been propagated by Elliot Eisner. The author contends that no concise formulation of the second position is yet been suggested. The position thus referred to embraces an innovative and novel approach to this conventional mission. Explication of this position is the main intention pursued in this article. The formulation presented here is gathered through a speculative inquiry approach. This position entails an integration on modernist and postmodernist views to curriculum

Sensing the delivery and endocytosis of nanoparticles using magneto-photo-acoustic imaging

Many biomedical applications necessitate a targeted intracellular delivery of the nanomaterial to specific cells. Therefore, a non-invasive and reliable imaging tool is required to detect both the delivery and cellular endocytosis of the nanoparticles. Herein, we demonstrate that magneto-photo-acoustic (MPA) imaging can be used to monitor the delivery and to identify endocytosis of magnetic and optically absorbing nanoparticles. The relationship between photoacoustic (PA) and magneto-motive ultrasound (MMUS) signals from the in vitro samples were analyzed to identify the delivery and endocytosis of nanoparticles. The results indicated that during the delivery of nanoparticles to the vicinity of the cells, both PA and MMUS signals are almost linearly proportional. However, accumulation of nanoparticles within the cells leads to nonlinear MMUS-PA relationship, due to non-linear MMUS signal amplification. Therefore, through longitudinal MPA imaging, it is possible to monitor the delivery of nanoparticles and identify the endocytosis of the nanoparticles by living cells

The place of multicultural education in the social science textbooks of the first secondary school and Iran\'s upstream documents with an emphasis on the feminist approach.

Background and Aim: Academic performance of students is an indicator by which their learning and progress is judged and many individual and environmental factors are effective in academic performance. The aim of the present study was to provide a structural model for explaining exam anxiety based on personality traits: evaluating the mediating role of cognitive and metacognitive strategies. Methods: The statistical population of the present study was made up of all female students of the second secondary school in Tehran in the academic year of 2018-19. The sampling method was a multi-stage cluster random method and the sample size was 421 people. The research tools include the five-factor questionnaire of Neo Costa and Makri (1989); Sarason et al.'s test anxiety scale (1956) and Dawson and McEnery's Cognitive and Metacognitive Strategies Questionnaire (2004). The structural equation modeling method was used to analyze the data. Results: The total path coefficient between personality neuroticism factor (p<0.01, β=0.492) and test anxiety is positive and significant at 0.01 level. Also, the total path coefficient between personality openness factor (p<0.01, β=0.186) and test anxiety was negative and significant at 0.01 level. The path coefficient between cognitive strategies and exam anxiety (p<0.05, β=0.196) on the one hand and the path coefficient between metacognitive strategies and exam anxiety (p<0.01, β=0.231) on the other hand The other was negative and significant at 0.05 and 0.01 levels, respectively. Indirect effect of conscientiousness traits (p<0.01, β=0.126), openness (p<0.01, β=0.121) and extraversion (p<0.01, β=0.079) Personality has a negative effect on test anxiety and is significant at the 0.01 level. On the other hand, the indirect effect of neuroticism (p<0.01, β=0.062) on exam anxiety was positive and significant at the 0.01 level. Conclusion: It is concluded that the structural model of the explanation of exam anxiety based on personality characteristics: evaluation of the mediating role of cognitive and metacognitive strategies can be applied

Regularized Capon Beamformer Using ℓ1-Norm Applied to Photoacoustic Imaging

Delay-and-Sum (DAS), as a non-adaptive beamforming method, is one of the most common algorithms used in Photoacoustic imaging due to its simple implementation. The results obtained from this algorithm suffer from low resolution and high sidelobes. The adaptive Minimum variance (MV) method improves the image quality compared to DAS in terms of resolution and contrast. In this paper, it is proposed to add a ℓ1-norm regularization term to the conventional MV minimization problem and create a new sparse beamforming method, named Modified-Sparse-Mv (ms-Mv)algorithm. In fact, the sparsity of the output is forced to the beampattern by adding this new sparse added term, which results in more noise reduction and sidelobe suppression compared to MV. The minimization problem is convex, and therefore, it can be solved using an iterative algorithm. The results show that the proposed MS-MV method improves the signal-to-noise-ratio for about 5.36 dB and 6.44 dB compared to DAS and MV, respectively, for the designed wire phantom.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Acoustical Wavefield Imagin
