A Comparison of Reading Measures as Indicators of Risk across Grade Levels
Chuang Wang,Bob Algozzine
Journal of Educational and Developmental Psychology , 2011, DOI: 10.5539/jedp.v1n1p85
Abstract: The purpose of this study was to assess relationships between early literacy skills of at-risk students assessed with curriculum-based and norm-referenced measures. Participants were students in first, second, and third grade. Trained examiners administered five curriculum-based reading passages and three norm-referenced reading subtests to each student. Strong relationships were evident between performance on the curriculum-based oral reading fluency assessments and the norm-referenced reading subtests of word attack, word identification and passage comprehension skills. Findings are discussed with regard to previous research and recommendations are provided for helping teachers and other professionals engaged in efforts to use assessment information in response to intervention as well as in targeting instructional support needed in reading.

Region graph partition function expansion and approximate free energy landscapes: Theory and some numerical results
Haijun Zhou,Chuang Wang
Physics , 2012, DOI: 10.1007/s10955-012-0555-1
Abstract: Graphical models for finite-dimensional spin glasses and real-world combinatorial optimization and satisfaction problems usually have an abundant number of short loops. The cluster variation method and its extension, the region graph method, are theoretical approaches for treating the complicated short-loop-induced local correlations. For graphical models represented by non-redundant or redundant region graphs, approximate free energy landscapes are constructed in this paper through the mathematical framework of region graph partition function expansion. Several free energy functionals are obtained, each of which use a set of probability distribution functions or functionals as order parameters. These probability distribution function/functionals are required to satisfy the region graph belief-propagation equation or the region graph survey-propagation equation to ensure vanishing correction contributions of region subgraphs with dangling edges. As a simple application of the general theory, we perform region graph belief-propagation simulations on the square-lattice ferromagnetic Ising model and the Edwards-Anderson model. Considerable improvements over the conventional Bethe-Peierls approximation are achieved. Collective domains of different sizes in the disordered and frustrated square lattice are identified by the message-passing procedure. Such collective domains and the frustrations among them are responsible for the low-temperature glass-like dynamical behaviors of the system.
Ground-state configuration space heterogeneity of random finite-connectivity spin glasses and random constraint satisfaction problems
Haijun Zhou,Chuang Wang
Statistics , 2010, DOI: 10.1088/1742-5468/2010/10/P10010
Abstract: We demonstrate through two case studies, one on the p-spin interaction model and the other on the random K-satisfiability problem, that a heterogeneity transition occurs to the ground-state configuration space of a random finite-connectivity spin glass system at certain critical value of the constraint density. At the transition point, exponentially many configuration communities emerge from the ground-state configuration space, making the entropy density s(q) of configuration-pairs a non-concave function of configuration-pair overlap q. Each configuration community is a collection of relatively similar configurations and it forms a stable thermodynamic phase in the presence of a suitable external field. We calculate s(q) by the replica-symmetric and the first-step replica-symmetry-broken cavity methods, and show by simulations that the configuration space heterogeneity leads to dynamical heterogeneity of particle diffusion processes because of the entropic trapping effect of configuration communities. This work clarifies the fine structure of the ground-state configuration space of random spin glass models, it also sheds light on the glassy behavior of hard-sphere colloidal systems at relatively high particle volume fraction.

Qin Zhang, Enchun Pan, Yuan He, Wei Hu, Chuang Wang
Open Journal of Preventive Medicine (OJPM) , 2014, DOI: 10.4236/ojpm.2014.46059
Abstract:

Objective: The aim of this study was to investigate the cancer incidence and mortality in Huai’an area, China, 2010. Methods: On basis of the criteria of data quality from National Central Cancer Registry (NCCR), data submitted from 8 registries in Huai’an area in 2010 were checked and evaluated. Descriptive analysis included incidence and mortality stratified by areas (urban/rural), sex, age group and cancer sites. Results: The crude incidence rate was 231.17/100,000 (males 276.04/100,000, females 183.87/100,000), age-standardized incidence rate by Chinese standard population (ASIRC) was 179.53/100,000 and by World standard population (ASIRW) was 177.24/ 100,000. The incidence rates increased rapidly in people aged 40 and over, and the peak ages of incidence were at 75 - 79 (males over 85, females at 75 - 79). The cancer mortality rate was 151.26/100,000 (186.06/100,000 in males and 114.58/100,000 in females), age-standardized mortality rate by Chinese standard population (ASMRC) was 116.67/100,000 and by World standard population (ASMRW) was 115.64/100,000. The mortality rates increased rapidly after the age of 50, reaching the peak at the ages over 85 in both males and females. Esophageal, lung, gastric, liver, colorectal, breast, pancreas, lymphoma, brain and central nervous system, cervical were the most common cancer incident sites. Esophageal, lung, liver, gastric, colorectal, pancreatic, brain and central nervous system, leukemia, breast and lymphoma were the most common cancer sites of death. Conclusions: The data quality of cancer registration is improving. As cancer burden remained high and was different between urban and rural areas, prevention and control should be implemented based on practical situation.

Effects of Ion Doping on the Optical Properties of Dye-Sensitized Solar Cells  [PDF]
Di Gu, Yanji Zhu, Zhigang Xu, Nan Wang, Chuang Zhang
Advances in Materials Physics and Chemistry (AMPC) , 2014, DOI: 10.4236/ampc.2014.410022
Abstract: Dye-sensitized solar cells (DSC) play a leading role in the third generation photovoltaics due to their low cost, easy fabrication process, high conversion efficiency and good stability. As a media of dye adsorption, electron transport, and electrolyte diffusion, the nanocrystalline semiconductor photoanode plays a key role during light-to-electricity conversion in DSC. This paper studies the influence of different ions doping and different concentration of ion doping on the electrical and optical properties of DSC, through the photoelectric property test of DSC. We learn that Zn2+ doped TiO2 photoanode is the best. At the same time there was an optimum doping concentration which was 0.05% (mole fraction).

Abstract: notheranostics – a review of recent publications Review (2929) Total Article Views Authors: Wang LS, Chuang MC, Ho JA Published Date August 2012 Volume 2012:7 Pages 4679 - 4695 DOI: http://dx.doi.org/10.2147/IJN.S33065 Received: 17 April 2012 Accepted: 14 May 2012 Published: 27 August 2012 Li-Sheng Wang, Min-Chieh Chuang, Ja-an Annie Ho Department of Biochemical Science and Technology, National Taiwan University, Taipei, Taiwan Abstract: Theranostics is referred to as a treatment strategy that combines therapeutics with diagnostics, aiming to monitor the response to treatment and increase drug efficacy and safety, which would be a key part of personalized medicine and require considerable advances in predictive medicine. Theranostics associates with both a diagnosis that tests patients for possible reactions to taking new medication and targeted drug delivery based on the test results. Emerging nanotechnology provides a great deal of opportunity to design and develop such combination agents, permitting the delivery of therapeutics and concurrently allowing the detection modality to be used not only before or after but also throughout the entire treatment regimen. The introduction of nanotheranostics into routine health care has still a long way to go, since evaluations on cytotoxicity, genotoxicity, and immunotoxicity of prospective nanotheranostics, demonstration of cost-effectiveness, and availability of appropriate accessible testing systems are still required. An extensive review, from a chemistry point of view, of the recent development of nanotheranostics and its in vitro and in vivo applications are herein presented.

Health (Health) , 2013, DOI: 10.4236/health.2013.58A3011
Abstract:

Aim: Common treatment options for obesity include a reduced-calorie diet, increased physical activity, behavioral modification, pharmacotherapy, and surgery. Ear acupressure may also be an effective adjunct therapy. Methods: This study used a randomized controlled design to test the effectiveness of auricular acupressure for weight reduction in young, Taiwanese adults with a BMI ≥ 23 kg/m2. Sixty-eight participants aged 18 to 20 years were recruited from Taiwanese universities at the beginning of the study. After four weeks of auricular therapy, the total sample included 57 young adults. All participants met one time per week for ten minutes. The treatment group received ear acupressure treatment with Semen Vaccariae sticks on auricular acupoints while the control group had adhesive tape placed on ear acupoints, change in BMI from baseline to trial completion. Results: BMI in controls increased significantly by +0.0133 kg/m2 (P = 0.000) while the intervention group BMI decreased significantly by ?0.8022 kg/m2 (P ≤ 0.0001). Conclusions: Just four weeks of auricular acupressure by Semen Vaccariae, sticks may significantly help to decrease BMI among young adults.

Impact of Single-sex Instruction on Student Motivation to Learn Spanish
Scott Kissau,Lan Quach,Chuang Wang
Canadian Journal of Applied Linguistics (CJAL) , 2009,
Abstract: To increase male motivation to learn additional languages studies have suggested teaching males in single-sex second and foreign language classes (Carr & Pauwels, 2006; Chambers, 2005). Despite the reported benefits of this unique arrangement, a review of literature found no related research conducted in Canada or the United States. To address this lack of research, a study was conducted in the spring of 2008 to investigate the impact of single-sex instruction on student motivation to learn Spanish. Using Gardner's model of second language motivation (1985), 57 high-school students studying Spanish in either single-sex or coeducational classes completed a pre and post questionnaire to gauge their motivation to learn the language. Follow-up interviews were also conducted with both students and teachers. Results indicated that while both sexes enjoyed some educational advantages from the single-sex environment, the benefits appeared to be greater for the males than the females.RésuméAfin d'accro tre la motivation des gar ons pour l'apprentissage des langues, certaines études ont suggéré d'enseigner les langues secondes ou étrangères à des classes de gar ons exclusivement (Carr & Pauwels, 2006; Chambers, 2005). Malgré le bénéfice confirmé d'un tel contexte, il n'existe aucune recherche similaire connue sur ce sujet au Canada ou aux états Unis. Pour remédier à cette lacune, on a conduit au printemps 2008 une étude portant sur l'impact de l'enseignement non mixte sur la motivation des élèves à apprendre l'espagnol. Selon le modèle de Gardner quant à la motivation dans l'apprentissage d'une langue seconde (1985), 57 élèves au niveau secondaire apprenant l'espagnol dans des classes mixtes et non mixtes ont rempli avant et après le cours, des questionnaires destinés à mesurer leur motivation. Le suivi a été assuré par le biais d' entrevues avec élèves et professeurs. Les résultats montrent que si les élèves des deux sexes bénéficiaient d' un environnement éducatif non-mixte, les gar ons semblaient en tirer plus d'avantages.
