It's Not Easy Being Green: Embodied Artifacts and the Guided Emergence of Mathematical Meaning

This on-going design-based research study focuses on Grade 4-6 students’ guided task-based interaction with a novel computer-based hand-tracking system built to suggest the limitations of naïve additive schemes and create opportunities to develop core notions of proportionality as elaborations on these schemes, even before engaging numerical semiotic forms. Study participants struggled with canonical issues inherent to rational numbers. They formulated a string of insights leading up to a new type of equivalence class. Reported as a case study of Itamar, a 5-grade middle-achieving student, our analyses reveal emergence of conceptually critical mathematical meanings in an activity that initially bears little mathematical significance.
Optimal schedule for 5-fluorouracil chemotherapy. Intermittent bolus or continuous infusion?

: 5-Fluorouracil (5-FU) remains the standard chemotherapy for gastrointestinal cancer, particularly colorectal cancer, with response rates of 8% to 33% and median survivals of 24 to 44 weeks. The schedule of delivery for 5-FU has been addressed in a number of clinical trials over the past two decades, but the optimal schedule based upon more recent studies is not clear. The prospective comparative trial by Ansfield et al., investigated bolus delivery in four schedules and the daily X 5 loading regimen was superior to the less intensive regimens. However, two randomized trials of bolus 5-day vs. continuous 5-day infusions have indicated that the infusion schedule is superior: in colorectal cancer, the study by Seifert et al. demonstrated a response rate of 42% for infusion vs. 21% for bolus; and in head and neck cancers 5-FU administered in conjunction with cisplatin achieved a response rate of 76% for infusion vs. 20% for bolus delivery. Further support for the superiority of the infusion schedule is provided by the comparative trials of hepatic arterial infusion (HAI) and systemic venous infusion, in which response rates are equivalent regardless of the route of delivery. In order to definitively establish an improved therapeutic effect for the infusion schedule, additional prospective trials comparing standard bolus schedules to infusion schedules are necessary, and should address other issues, such as the optimal duration of infusion and relative cost-effectiveness.
A declarative domain independent approach for querying and generating visualizations

Constructing visualizations using modular visualization environments (MVEs) requires knowledge about visualization transformation theory as well as implementation specific details about how to programmatically chain together relevant sets of modules into pipe and filter-like architectures known as pipelines. Constructing visualization pipelines introduces a number of challenges including: understanding how to transform raw data into forms that can be ingested by MVEs, identifying target modules that map data into graphical data, and understanding how to further transform resulting graphical data into forms that can be presented. Users typically must immerse themselves in a deluge of documentation and usage examples before becoming proficient in the aforementioned tasks and therefore able to generate suitable visualizations required for analysis. This dissertation presents a visualization query language that was designed with the goal of hiding the associated complexities of visualization pipeline construction by abstracting away implementation specific details. By posing visualization queries, users can declaratively specify what visualizations they want generated from their data and quickly explore a variety of results that may only be generated using complex combinations of modules possibly supported across different MVEs. This dissertation explores the query answering facilities associated with visualization queries as well as presenting a pilot study which supports the claim that users both prefer and are more proficient at using queries than writing traditional pipeline-based code.
On the Marriage of Edit Distance and Lp Norms

A rolling parallel printer in which a pressure element is driven through a swiveling motion each printing cycle and a pressure segment thereof rolls off a line of type. The pressure element is connected to a mechanical linkage which minimizes the sweep of travel of the pressure element, while maintaining the pressure element sufficiently far from the type in a rest position to facilitate reading of the printed matter.
PREGNANCY IN MYOTONICA DYSTROPHIA

MYOTONICA dystrophia is a rare familial disease characterized by muscular atrophy accompanied by the phenomenon of myotonia. The latter is manifested by delay and difficulty in relaxing muscles after their initial contraction. Myotonia may be unrelated to the wasting both in the muscle groups affected and its time of onset. The muscular atrophy is particularly seen in the sterno-mastoids, the facial muscles, the muscles of the forearm and the dorsiflexors of the ankle. Pregnancy is uncommon in myotonica dystrophia and its effects have in the main been gleaned from retrospective reminiscences of patients at family surveys held long afterwards. De Jong (1956) quotes Gardiner (1901) who described a pregnant woman with myotonia which commenced at the sixth month and which cleared after delivery. Also de Jong quotes Weber (1945) as having described a multipara who in all her pregnancies developed muscular stiffness. The following case describes a pregnancy and delivery occurring in a woman who was suffering from myotonica dystrophia.

Factors Associated With Injection and Noninjection Drug Use During Incarceration Among Puerto Rican Drug Injectors in New York and Puerto Rico

This study examines factors related to injection and noninjection drug use during the last incarceration among injection drug users in East Harlem, New York (n = 555), and Bayamón, Puerto Rico (n = 241). Injecting drugs during the last incarceration episode was more likely in the sample in Puerto Rico (31% vs. 12%, p < .001), and noninjection drug use was more likely in the New York sample (37% vs. 14%, p < .001). Gang affiliation and length of incarceration were related to injection and noninjection drug use. Interventions for incarcerated drug users, including harm reduction efforts and drug treatment programs, should be enhanced. Further study of the role of gangs in influencing inmate HIV risk behaviors should be undertaken.

Schistosomiasis mansoni in school attenders and non-attenders in Northwest Ethiopia

Abstract Background: Information on epidemiology of schistosomiasis in school age children and particularly non school attenders are scanty in northwestern Ethiopia. Objective: To assess the prevalence of Schistosoma mansoni in school attenders and non-attenders in Northwest Ethiopia. Methods: A parasitological survey was carried out from June 1995 - July 1997 in selected communities and schools. Results: Of the 199 community based school attenders in Zarima, 198 in Gorgora and 200 in Dek, 85%, 67% respectively were positive for S. mansoni. Of the non-attenders in Zarima, 60(50%) in Gorgora and 90(44%) in Dek were positive for S. mansoni. Among school attenders the intensity of infection (mean egg count) was fond to be 177 eggs per gram (epg), 139 epg, and 135 epg in Zarima, Gorgora and Dek respectively. Among non - attenders the intensity of infection was 166 epg, 100 epg, and 121 epg in Zarima, Gorgora, and Dek respectively. The study demonstrates that the infection rates and the intensities of infection of S. mansoni were higher in school attenders than in non-attenders. The difference in prevalence was statistically significant (P<0.01). The difference in intensity of infection was statistically significant only in Gorgora (P<0.05). Conclusion: Focussing treatment intervention measures on school attenders would be an appropriate approach in Northwest Ethiopia. [Ethiop. J. Health Dev. 2001;15(2):117-123]
Word level literacy skills of adolescents and their teachers : an exploratory mixed methods study : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in Education at Massey University, Manawatu, New Zealand

Poor adolescent reading comprehension is a persistent problem which is difficult to solve because of its complexity. The contribution made by the word level skills of decoding and spelling to skilled reading has been under-researched in New Zealand. Relationships between word level abilities and reading comprehension were investigated in an exploratory study of 301 adolescents aged from 12 to 14 from six secondary schools in the lower North Island of New Zealand. Word level knowledge was assessed through pseudoword and real word spelling tasks whilst vocabulary knowledge was assessed using a standardised reading vocabulary assessment and a morphological awareness task. Results demonstrated that spelling was more difficult than reading comprehension, and that whilst most adolescents in the sample had a grasp of the alphabetic principle, many had weak knowledge of English orthography and morphology. Regression analysis showed that vocabulary knowledge made the greatest contribution to reading comprehension. The contribution of spelling, although quite small, was significant. This finding suggested that an intervention focused on developing orthographical and morphological knowledge might have a beneficial influence on reading comprehension abilities. An intervention focused on developing orthographic and morphological awareness, delivered by classroom teachers, consisted of bi-weekly word study sessions over 21 weeks. The intervention aimed to improve spelling and decoding skills for weaker students and vocabulary knowledge and word consciousness for all students. Moreover, the intervention also aimed to increase teachers’ word level literacy knowledge by exposing them to interactive word study activities intended to engage students’ interest. Post intervention assessments results showed no intervention effects for standardised spelling, vocabulary or reading comprehension. However, gains were found in pseudoword spelling and morphology tasks. Qualitative evidence supported the role of the intervention in developing word consciousness for a number of participants. There was evidence from a word level

Fireball: a forensic ballistics imaging system

Characteristic markings on the cartridge and projectile of a bullet are produced when a gun is fired. Over thirty different features within these markings can be distinguished, which in combination produce a "fingerprint" for identification of a firearm. This paper will describe an investigation into the development of an imaging system for Police Services which can store, analyse, retrieve, and match high resolution digital images of cartridge cases. A computerised imaging system for ballistics identification will produce efficiencies in time and personnel, and permit a more precise audit of firearms within a country. The project has produced good quality high resolution digitised images of cartridge cases for the identification function. The development of the optical system to optimise image quality has been crucial for the image identification phase. By classifying cartridge image attributes, it is possible to store the unique "signatures" of cartridge cases for identification. Appropriate image processing provides the signatures for the image library. The Fireball forensic ballistics interactive database incorporates a Graphics User Interface (GUI) to obtain precise ballistics metrics of cartridge case class characteristics. Features of the Fireball forensic ballistics database will be presented, together with a description of the major applications of this ballistics imaging system.
Investigation of the Association between rs4977574 A > G Polymorphism in ANRIL Gene and Coronary Artery Disease in Iranian Population

Background: Coronary Artery Disease (CAD) is an important disease where the arteries and vessels supplying oxygen and nutrients to the heart are narrowed or blocked. Early diagnosis and recognition of CAD leads to its complete treatment. Drug therapy, angiography, coronary angioplasty, and in advanced cases, coronary artery bypass surgery restore the normal flow of blood to the heart muscle. Objectives: The present study aimed to identify the association between rs4977574 polymorphism in ANRIL gene and CAD in Iranian patients. Materials and Methods: Blood samples were collected from 100 subjects with positive angiography (case group) and 93 ones with negative angiography (control group). Using Taq Man Real Time PCR, the extracted DNAs from the patients and controls were genotyped for rs4977574 polymorphism in ANRIL gene (applied biosystem, USA). Then, the genotypes and clinical parameters were compared by the SPSS statistical software, version 18 (Chicago, USA). The results were compared by one-way ANOVA, simple T-test, and Chi-square test and were presented as mean ± Standard Deviation (SD). P values < 0.05 were considered as statistically significant. Results: The results showed a significant relationship between CAD and Diastolic Blood Pressure (DBP), Body Mass Index (BMI), uric acid, Low Density Lipoprotein (LDL), cholesterol, and triglyceride. However, no significant association was observed between rs4977574 polymorphism and biochemical characteristics in the two groups. Allele frequency was AA = 22%, AG = 44%, and GG = 34% in the case group and AA = 17%, AG = 44%, and GG = 32% in the control group. Conclusions: The present study examined the association between rs4977574 polymorphism in ANRIL gene and CAD in a population of Iranian patients. The study findings revealed no direct relationship between rs4977574 polymorphism and the disease in Iranian population.
Propagation measurements at microwave frequencies for microcellular mobile and personal communications

A series of measurements was conducted in both rural and semiurban areas to measure radio propagation characteristics at microwave and millimeter-wave frequencies in a microcellular mobile radio environment where transmission is essentially line-of-sight (LOS). Measurements were made at 11 GHz with a fixed-site antenna located at the side of the road at heights of up to 30 ft. Data have been taken with both omnidirectional and directional antennas on the mobile, to compare received signal characteristics. It was found that, in rural and semiurban environments, propagation is dominated by interference between the direct ray and a specular, roadway-reflected ray. The average power received does not decay any faster than 1/r/sup 2/ over the measured range of transmitter-to-receiver separation. A wideband communication channel looks feasible, since the dual-ray interference effects and the random components of the received signals can be overcome by simple methods such as higher antenna directivity or space diversity. <<ETX>>
The effect of audio narration in computer-mediated instruction on procedural fluency by students of varying reading levels

This study compares the effect of text-based and narration-based multimedia presentation modalities on the accuracy and efficiency of procedural performance, a combination that the introduction to the New Standards for Elementary, Middle, Secondary, and Continuing Education of the New York State Education Department uses as the definition of “procedural fluency” (New York State Education Department, 2005). In addition, this study also examines the influence of reading skill on both procedural fluency resulting from and student choices of presentation modalities. By studying community college students with low computerized placement test scores, a wide range of reading skill levels was sampled. The independent variable, was the mode of presentation (text only, narration only, and learner's choice) in instruction to teach a new computer procedure. While results showed no overall advantage for any of the treatment conditions in procedural fluency, improvement was seen in the amount of time it took for students to complete the tutorial lesson when they were allowed to choose their preferred mode for receiving the lesson. The results showed that a disproportionately large portion of those students who failed to complete the procedure at all had been placed into the mode where reading was chosen for them. It was recommended that unless other factors dictate that the use of spoken presentations is counter-productive to the learning at hand, narration be included as an alternative presentation modality. This was recommended to increase the accessibility of the instructional product, to reduce the amount of time spent going through the lesson, and to increase the likelihood that learning of the procedure will take place. * *This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).

Approaching conformal window of $O(n)\times O(m)$ symmetric Landau-Ginzburg models from conformal bootstrap

$O(n) \times O(m)$ symmetric Landau-Ginzburg models in $d=3$ dimension possess a rich structure of the renormalization group and its understanding offers a theoretical prediction of the phase diagram in frustrated spin models with non-collinear order. Depending on $n$ and $m$, they may show chiral/anti-chiral/Heisenberg/Gaussian fixed points within the same universality class. We approach all the fixed points in the conformal bootstrap program by examining the bound on the conformal dimensions for scalar operators as well as non-conserved current operators with consistency crosschecks. For large $n/m$, we show strong evidence for the existence of four fixed points by comparing the operator spectrum obtained from the conformal bootstrap program with that from the large $n/m$ analysis. We propose a novel non-perturbative approach to the determination of the conformal window in these models based on the conformal bootstrap program. From our numerical results, we predict that for $m=3$, $n=7\sim 8$ is the edge of the conformal window for the anti-chiral fixed points.
Características e gastos com alimentação fora do domicílio no Brasil

OBJETIVO: Analisar as caracteristicas da alimentacao fora do domicilio e os gastos com o seu consumo. METODOS: Foi analisada uma amostra complexa de 48.470 domicilios brasileiros, selecionados a partir da base de dados da Pesquisa de Orcamentos Familiares de 2002-2003. O consumo de alimentos fora do domicilio foi definido como a aquisicao de, pelo menos, um tipo de alimento para consumo fora de domicilio no periodo de sete dias. Foram estimadas frequencias de consumo de alimentos fora do domicilio segundo idade, sexo, nivel de escolaridade, renda mensal familiar per capita, numero de moradores por domicilio, regioes brasileiras, situacao do domicilio (urbano/rural) e capital ou outro municipio. Nove grupos de alimentos foram estudados: bebidas alcoolicas, refrigerantes, biscoitos, frutas, doces, leite e derivados, refeicoes, fast foods e salgados fritos e assados. RESULTADOS: A frequencia de consumo de alimentos fora do domicilio foi de 35%, sendo maior na regiao Sudeste (38,8%) e menor na regiao Norte (28,1%). A frequencia foi maior entre os individuos de 20 a 40 anos (42%), do sexo masculino (39% vs. 31%), com maior nivel de renda (52%) e maior escolaridade (61%). Os alimentos mais frequentemente consumidos fora do domicilio foram: refrigerantes (12%), refeicoes (11,5%), doces (9,5%), salgados fritos e assados (9,2%) e fast foods (7,2%). O consumo dos grupos de alimentos cresceu linearmente com a renda, exceto para frutas e biscoitos. Os gastos medios semanais foram menores para biscoitos (R$ 1,79) e doces (R$ 2,02) e maiores para refeicoes (R$ 21,56). CONCLUSOES: O consumo de alimentos fora do domicilio e frequente em todas as regioes do Brasil. As politicas publicas devem incorporar essa dimensao ao propor estrategias de alimentacao saudavel.
Fault-tolerant Scheduling of Real-time Parallel Tasks with Energy Efficiency on Multicore Processors

By exploiting parallel processing, the proposed scheduling scheme enhances energy saving capability of multicore processors for real-time tasks while satisfying deadline and fault tolerance constraints. The scheme searches for a near minimum-energy schedule within a polynomial time, because finding the minimum-energy schedule on multicore processors is a NP-hard problem. The scheme consumes manifestly less energy than the state-of-the-arts method even with low parallel processing speedup as well as with high parallel processing speedup, and saves the energy consumption up to 86%.
