Peer Teaching and Learning: Co-constructing Language in a Dual Language First Grade

This paper presents findings from a study of teaching and learning strategies co-constructed by peers in a Spanish/English dual language first grade classroom. Grounded in sociocultural theory and developed using ethnographic approaches to data collection and analysis, the study analyses the children’s mediation of their own and each other’s language learning within and across languages, focusing on strategies that support learning. The strategies are analysed within the context of teaching/learning interactions in a Dual Language Programme with attention given to the children’s ongoing negotiation of the linguistic roles of novice, expert, and dual language expert when working in mixed groups in the English and Spanish classrooms.
Density and spatial resolutions of proton radiography using a range modulation technique

The image quality of proton radiography using the method of beam energy modulation was studied to look into its practical uses. Two different depth–dose distributions generated by modulation were applied to investigate their effects on the density and spatial resolutions of the radiographic image. A steeper slope was found to provide higher resolution for the matching thickness of a phantom. The image was taken on a scintillation screen, and the distance between the phantom and the screen was a sensitive parameter on the resolution. For a beam with a range of 1.2 cm in Lucite, high-resolution images were attainable in the whole range. The resolution of proton images for different kinds of phantoms was examined in comparison with x-ray images as well as images simulated by a Monte Carlo code MCNPX. For a longer range of 18 cm, images attained by simulations indicated that density resolution is better maintained compared to spatial resolution, which is deteriorated by multiple Coulomb scattering.
Interpreting and Extending G. H. Mead's “Metaphysics” of Selfhood and Agency

G. H. Mead developed an alternative “metaphysics” of selfhood and agency that underlies, but is seldom made explicit in discussions of, his social developmental psychology. This is an alternative metaphysics that rejects any pregiven, fixed foundations for being and knowing. It assumes the emergence of social psychological phenomena such as mind, self, and deliberative agency through the activity of human actors and interactors within their biophysical and sociocultural world. Of central importance to the emergence of self-consciousness and deliberative forms of human agency is the ability of developing individuals to take the perspectives of others within their own conduct. However, precisely what is involved in this process, and whether or not it assumes the preexistence of exactly those forms of selfhood and agency, the emergence of which it seeks to explain, have been much disputed. In this essay, recent reinterpretations of Mead's “metaphysics” are used to argue that his overall theoretical program contains resources necessary to overcome charges of ontological and epistemological circularity. In particular, once his interactionism, perspectivism, emergentism, and compatibilism are explicated, it is possible to see that Mead's “taking the perspective of the other” is not primarily a process of internalization that requires a preexisting “internalizer,” but a process of participation with others within conventionalized sequences of interactivity. This participatory process enables the development of prereflective forms of perspective taking and self–other differentiation that serve as necessary conditions for the further emergence of more reflective forms of perspective taking, self-consciousness, and deliberative agency. Compatibilist interpretations of deliberative agency, thus understood, also are discussed.
Communicative Spontaneity of Children with High Support Needs who use Augmentative and Alternative Communication Systems I: Classroom Spontaneity, Mode, and Function

In the present study, the communicative spontaneity of 23 children with high support needs who used Augmentative and Alternative Communication (AAC) in a classroom setting was evaluated. In contrast to previous research, spontaneity was evaluated on a continuum rather than being treated as a binary variable. Spontaneity was found to be highly variable, but some students clearly lacked the range of spontaneity that would be associated with fully functional communication. Aided AAC systems were notably less spontaneous than signing or nonsymbolic communication. There was also evidence of systematic variation in spontaneity across pragmatic function, with instrumental functions being more spontaneous than commenting. The results of the present study highlight the need to consider spontaneity when assessing individuals who use AAC systems.
Minimally Invasive Plate Osteosynthesis for Tibial Plateau Fractures

Purpose. To evaluate radiological and clinical outcome of minimally invasive plate osteosynthesis (MIPO) for tibial plateau fractures. Methods. 35 men and 6 women aged 19 to 75 (mean, 40; standard deviation [SD], 14) years underwent MIPO for displaced tibial plateau fractures. According to the Schatzker system, the tibial plateau fractures were classified as types I (n=3), II (n=9), III (n=11), IV (n=6), V (n=7), and VI (n=5). Six patients had open fractures; 2 of them underwent debridement before MIPO. 10 patients needed additional bone grafting. Radiological (at immediate postoperation) and clinical (at the 12-month follow-up) assessments based on the Rasmussen anatomic and functional scoring system were recorded using a proforma. Patients with acceptable and unacceptable outcomes were compared in terms of age. Results. The mean Rasmussen anatomic score was 15.1 (SD, 2.2; range, 10–18); the mean Rasmussen functional score was 25.3 (SD, 3.2; range, 14–29); and the mean range of knee motion was 118° (SD, 10°; range, 90°–140°). Anatomic outcome was excellent in 10, good in 28, and unacceptable in 3 patients (one each had Schatzker type-I, -II, and -III fractures). 27 (71%) of the 38 patients with acceptable anatomic outcome were aged ≤45 years, whereas 2 (67%) of the 3 patients with unacceptable anatomic outcome were aged ≥60 years (p=0.001). Functional outcome was excellent in 18, good in 19, and unacceptable in 4 patients (2 had Schatzker type-III and another 2 had Schatzker type-I or -II fractures). 37 of the patients had a range of knee motion of ≥120°; 27 (73%) of them were age d ≤45 years, whereas 3 (75%) of the 4 patients with unacceptable functional outcome were aged ≥60 years (p=0.001). Conclusion. MIPO for tibial plateau fractures achieved good outcome with minimal soft-tissue complications. Older age was the predictor of unacceptable outcome.
Supporting the dynamic evolution of Web service protocols in service-oriented architectures

In service-oriented architectures, everything is a service and everyone is a service provider. Web services (or simply services) are loosely coupled software components that are published, discovered, and invoked across the Web. As the use of Web service grows, in order to correctly interact with them, it is important to understand the business protocols that provide clients with the information on how to interact with services. In dynamic Web service environments, service providers need to constantly adapt their business protocols for reflecting the restrictions and requirements proposed by new applications, new business strategies, and new laws, or for fixing problems found in the protocol definition. However, the effective management of such a protocol evolution raises critical problems: one of the most critical issues is how to handle instances running under the old protocol when it has been changed. Simple solutions, such as aborting them or allowing them to continue to run according to the old protocol, can be considered, but they are inapplicable for many reasons (for example, the loss of work already done and the critical nature of work). In this article, we present a framework that supports service managers in managing the business protocol evolution by providing several features, such as a variety of protocol change impact analyses automatically determining which ongoing instances can be migrated to the new version of protocol, and data mining techniques inferring interaction patterns used for classifying ongoing instances migrateable to the new protocol. To support the protocol evolution process, we have also developed database-backed GUI tools on top of our existing system. The proposed approach and tools can help service managers in managing the evolution of ongoing instances when the business protocols of services with which they are interacting have changed.
Gender Differences in Fear of Terrorism

Researchers have long been curious about the mismatch between women's fear of crime and their objective risk of victimization. The present research, which examines fear of terrorism, provides a unique opportunity to explore gender differences in reactions to a specific type of violent victimization, terrorism. The article analyzes data collected from a telephone survey of 532 inhabitants from New York and Washington on the topic of reactions to terrorism-related information. Analysis of these data finds that women are more fearful, engage in more avoidance behaviors, and are more likely to seek information in response to terrorism-related information. Moreover, women differ from men in predictors of their terrorism fears as well as engagement in terrorism-related avoidance and information-seeking behaviors. Possible explanations for these results are discussed.
Body Image and Nutritional Status Are Associated with Physical Activity in Men and Women: The ELSA-Brasil Study

The association of body image dissatisfaction and obesity with physical activity is likely to differ according to gender. To investigate this hypothesis, we conducted a cross-sectional study among the ELSA-Brasil cohort members aged 34–65 years (n = 13,286). The body image dissatisfaction was present even among normal weight individuals of both sexes and was associated with lesser chances of practicing moderate physical activity in women and intense physical activity in men. Men and women with central obesity were less prone to practice physical activity of high or moderate intensity. Overweight and obese men were more likely to report vigorous physical activity while obese women were less likely to report this level of physical activity. Body images as well as nutritional status are related to physical activity in both sexes, but the association with physical activity differs by gender.
Effective Transmission of Light for Media Culture, Plates and Tubes

The results of many investigations on low‐level laser therapy are contradictory and this is due to the large number of illumination parameters as well as the inability to measure the possible effects after irradiation with the necessary objectivity and the fact that the light needs to pass thorough barriers (usually the plastic of the culture dish/plate and culture medium) to reach the cells. In this manner, the objective of this study was to determine the absorption coefficient, penetration depth and effective transmission in materials commonly used in cell cultures. Among the most commonly used wavelengths in low‐level laser therapy, the lowest absorption coefficients were reached by DMEM and RPMI (α = 0.03 cm−1), from 633 to 690 nm, which reach an effective transmission of 93% of incident radiation and penetration depth of 33 cm. Among the solid materials in the same range of the electromagnetic spectrum, the lowest absorption coefficient was obtained for the polystyrene (Petri dish and well plate), with α = 1.31 cm−1, 78% of effective transmission and 0.76 cm of penetration depth. This article also presents a simple equation for estimating the amount of energy that will actually reach the sample.
Starting a sport in the Netherlands: A life-course analysis of the effects of individual, parental and partner characteristics

In this article we investigate the effects of parental, individual and partner characteristics on the starting of a sport. Employing event history models we analyze 72,491 person-years of 2276 individuals from the Family Survey Dutch Population 1998 and 2003. Our results show that growing up in a family in which sport is common increases the likelihood of starting a sport. We further conclude that parents from the higher social classes more often stimulate their children to start participating in a high status sport. Our results also indicate that a respondent’s educational attainment is positively related to enrollment in sports. The importance of a spouse is particularly demonstrated, as a sport-playing partner expresses a positive influence on a respondent’s sport participation. Moreover, in starting a sport it is more favorable not having a partner, even than having a non-sporting spouse.
Differentiating Symptoms of Complicated Grief and Depression among Psychiatric Outpatients

Objective: This study examined whether dimensions of complicated grief (CG) could be distinguished from dimensions of depression and whether these dimensions were differentially affected by group psychotherapy for CG. Method: A total of 398 psychiatric outpatients who had experienced one or more significant death losses provided ratings on standard measures of grief and depression. Factor analysis of the 56 items from these measures was used to explore the possibility that grief and depression symptoms would form separate dimensions of distress. Subsamples of the patients also participated in 1 of 2 forms of short-term group therapy for CG. Repeated-measures analysis of variance and calculation of effect sizes were performed to examine changes in the dimensions following treatment. Results: The grief items formed 3 distinct clusters representing different dimensions of CG. None of the depression items loaded highly on these grief dimensions. The depression items formed 2 distinct clusters. Two of the grief dimensions demonstrated the most improvement following group therapy that addressed CG. There was also evidence for differential effectiveness of the 2 forms of group therapy. Conclusions: When assessing psychiatric patients who have death losses, clinicians should consider different types of grief reactions. Different types of grief reactions may be responsive to different treatments. In the absence of depressive symptoms, clinicians should not assume the absence of CG.
Effects of temperature and handling conditions on lipid emulsion stability in veterinary parenteral nutrition admixtures during simulated intravenous administration.

OBJECTIVE To determine whether lipid particle coalescence develops in veterinary parenteral nutrition (PN) admixture preparations that are kept at room temperature (23 degrees C) for > 48 hours and whether that coalescence is prevented by admixture filtration, refrigeration, or agitation. SAMPLE POPULATION 15 bags of veterinary PN solutions. PROCEDURES Bags of a PN admixture preparation containing a lipid emulsion were suspended and maintained under different experimental conditions (3 bags/group) for 96 hours while admixtures were dispensed to simulate IV fluid administration (rate, 16 mL/h). Bags were kept static at 4 degrees C (refrigeration); kept at 23 degrees C (room temperature) and continuously agitated; kept at room temperature and agitated for 5 minutes every 4 hours; kept static at room temperature and filtered during delivery; or kept static at room temperature (control conditions). Admixture samples were collected at 0, 24, 48, 72, and 96 hours and examined via transmission electron microscopy to determine lipid particle diameters. At 96 hours, 2 samples were collected at a location distal to the filter from each bag in that group for bacterial culture. RESULTS Distribution of lipid particle size in the control preparations and experimentally treated preparations did not differ significantly. A visible oil layer developed in continuously agitated preparations by 72 hours. Bacterial cultures of filtered samples yielded no growth. CONCLUSIONS AND CLINICAL RELEVANCE Data indicated that the veterinary PN admixtures kept static at 23 degrees C are suitable for use for at least 48 hours. Manipulations of PN admixtures appear unnecessary to prolong lipid particle stability, and continuous agitation may hasten lipid breakdown.
A Comparison of Teachers’ and Parents’ Knowledge and Beliefs About Attention-Deficit/Hyperactivity Disorder(ADHD)

The Knowledge about Attention Deficit Disorder Questionnaire (KADD-Q) was administered to 256 teachers and 92 parents. Statistical analysis revealed the KADD-Q to be an internally consistent measure of teachers’ and parents’ knowledge of ADHD. Findings demonstrated that the levels of teachers’ and parents’ knowledge about the causes of ADHD was significantly higher than their knowledge of the characteristics of ADHD, which in turn was significantly higher than their knowledge about treatment. When the total scores of teachers and parents were compared, the latter scored significantly higher. Although there were no significant differences in teachers’ and parents’ levels of knowledge about the Characteristics of ADHD, parents scored significantly higher than teachers on the Causes and Treatment subscales of the KADD-Q. The findings also revealed that misconceptions about ADHD are evident among parents and teachers, but that professional development is significant in increasing knowledge.
HBaseSpatial: A Scalable Spatial Data Storage Based on HBase

Recent years, the scale of spatial data is developing more and more huge and its storage has encountered a lot of problems. Traditional DBMS can efficiently handle some big spatial data. However, popular open source relational database systems are overwhelmed by the high insertion rates, querying requirements and terabytes of data that these systems can handle. On the other hand, key-value storage can effectively support large scale operations. To resolve the problems of big vector spatial data's storage and query, we bring forward HBase Spatial, a scalable spatial dada storage based on HBase. At first, we analyze the distributed storage model of HBase. Then, we design a distributed storage and index model. Finally, the advantages of our storage model and index algorithm are proven by experiments with both big sample sets and typical benchmarks on cluster compared with MongoDB and Mysql, which shows that our model can effectively enhance the query speed of big spatial data and provide a good solution for storage.
Intercaste Marriage: A Study from the Indian Context

Marriage in India is primarily based on social stratification of a caste system. In this article we discuss the issues and challenges faced when defying the traditional culture of arranged marriage to enter into an intercaste marriage in the rural Indian context. Guided by the ecocultural theory, we used qualitative methods to collect the data based on phenomenological principles. Data for this study were collected through in-depth interviews with 15 couples who were recruited through purposive and snowball methods. Two key themes emerged during discussions with participants: one from the social context and the other from the personal context. The study findings suggest that even today the caste system is largely prevalent in rural India, which condemns intercaste marriage, and the couple who tries to defy this norm faces dire consequences. We also provide insights to the logic behind the propagation of arranged marriages from the Hindu religion perspective.
Perineuronal net degradation in epilepsy

We previously reported loss of perineuronal net (PN) immunohistochemical staining around parvalbumin‐positive interneurons in the hippocampus of rats after an episode of status epilepticus (SE). We hypothesized that the loss of the PN could alter seizure susceptibility and that matrix metalloproteinases (MMPs) were candidates for degradation of the PN following SE.
Microscopic alterations of vaginal tissue in women with pelvic organ prolapse

The aim of this study was to identify any histological changes between the prolapsed and non-prolapsed vaginal skin to enable us to answer the broader question of whether to excise or re-suture the prolapsed tissue during vaginal reconstructive surgery. Two tissue samples were taken from 20 women who underwent prolapse surgery, one prolapsed and another non-prolapsed tissue. The samples were analysed blind histologically by a pathologist. Our study showed statistically significant differences in three tissue components namely myofibroblast differentiation (0.047), elastin (0.048) and collagen (0.095), depending on whether the tissue was prolapsed or non-prolapsed. However, the study had certain limitations and practical difficulties faced in histological approach of tissue analysis. Histology alone is an insufficient indicator to answer our question and definitive understanding of the prolapsed tissue may result from a randomised study on a larger study population.
Vinegar Intake Reduces Body Weight, Body Fat Mass, and Serum Triglyceride Levels in Obese Japanese Subjects

Acetic acid (AcOH), a main component of vinegar, recently was found to suppress body fat accumulation in animal studies. Hence we investigated the effects of vinegar intake on the reduction of body fat mass in obese Japanese in a double-blind trial. The subjects were randomly assigned to three groups of similar body weight, body mass index (BMI), and waist circumference. During the 12-week treatment period, the subjects in each group ingested 500 ml daily of a beverage containing either 15 ml of vinegar (750 mg AcOH), 30 ml of vinegar (1,500 mg AcOH), or 0 ml of vinegar (0 mg AcOH, placebo). Body weight, BMI, visceral fat area, waist circumference, and serum triglyceride levels were significantly lower in both vinegar intake groups than in the placebo group. In conclusion, daily intake of vinegar might be useful in the prevention of metabolic syndrome by reducing obesity.
Context-evoked overperception in asthma

We investigated associative learning as a possible explanation of overperception in asthma. Thirty newly diagnosed patients with asthma (eight men) underwent a histamine provocation to elicit airway obstruction (Cockcroft's protocol). Patients testing positive and reporting symptoms underwent an identical procedure on the next day with saline, a substance that does not elicit any significant airway changes. Symptoms of airway obstruction and fatigue increased significantly from pre- to post-saline inhalation on day 2, whereas physiological parameters did not change. Increases in symptoms were significantly related to the level of dispositional negative affectivity, but not to the degree of airway reactivity or changes in objective lung function. These results suggest that the experience of asthmatic symptoms in a specific context may evoke the experience of similar symptoms when confronted with the context only. Learning was more likely to occur in those patients with high negative affectivity.
