Las Siete Historias: Perceptions of Parent Involvement Among Mexican Immigrant Women
Authors: Thomas-Duckwitz Claire M. , Hess Robyn S. , Atcherly Elsa 
Published: June 2013

Abstract
This multiple case study examined parent involvement perspectives among seven immigrant mothers from Mexico. All the participants came from limited educational and socioeconomic backgrounds, and reported that they immigrated to the United States for greater opportunity. These background experiences seemed to shape their current role conceptualizations with respect to parent involvement. Parents viewed their roles as providing a better life for their children and facilitating their school success through actions taken at home. Invitations by school staff were important to help these mothers more effectively fulfill their roles through two-way communication. The findings of this study suggest the importance of helping school staff to better understand the ways that immigrant families view parent involvement and to facilitate partnerships in order to enhance student outcomes.
Cultural Signification through Reader’s Theatre: An Analysis of African American Girls and Their Hair
Authors: Jeffries Rhonda , Jeffries Devair 
Published: June 2013

Abstract
This article explored the role of hair in Sylviane Diouf’s Bintou’s Braids and focused on the impact of hair as a cultural signifier on girls and the curriculum. The article examined the ability of this children’s text to address female beauty standards and suggests the use of literary techniques, such as reader’s theatre, to recognize and critically explore diverse issues among children. The work specifically: (1) deconstructs messages about hair norms, with particular emphasis on black female hair in one children’s text, and (2) transforms the selected text into a reader’s theatre script for use in elementary classrooms, suggesting an array of literary construction and usage types in children’s classroom communities to support increased literacy engagement. This article expands the body of inquiry on hair and its impact on the curriculum by examining the relationships between the cultural power of hair, literacy, performance and African American girls. The literature has established the unique responses of diverse girls to literary constructions, and several studies provide alternatives for deciphering the meaning of texts and utilizing the empowering aspect of girls through literacy. Likewise, this article qualitatively examined Diouf’s Bintou’s Braids for its use of various aspects of identity development such as affirmation, ritual and social responsibility. The reader’s theatre adaptation, Little Bintou Loves Her Braids, begins to address the current inadequacy of literary offerings in the genre.
The CSE Software Challenge — Covering the Complete Stack
Authors: Köstler Harald , Rüde Ulrich 
Published: June 2013

Abstract
Typical applications in Computational Science and Engineering (CSE) try to extract information based on a model out of given data, for example to understand physical effects based on numerical simulations. The involved numerical algorithms tend to be complex and their understanding and design require deep mathematical knowledge. Moreover, for physically meaningful results, high accuracy and large-scale problems have to be solved. Writing software for such applications in CSE is a difficult task, since the complex models have to be implemented efficiently on large High Performance Computing (HPC) systems. Therefore, parallel algorithms have to be developed that fit to the underlying parallel hardware, and tools are necessary to analyze and tune the code. In this article we first summarize the demands on CSE software design in general and then present the multi-physics software framework waLBerla as an example for efficient, portable, and productive CSE software.

Abstract
The future of HPC is simple to predict: we will have faster and more capable systems in the future. That is because the need for more is so strong that such systems will be created. A key development in HPC has been this great growth in demand from many sectors. That development, it turns out, supplies the demand but also asks for more accessible and efficient solutions. The exact hardware and software that will win is more difficult to predict, but trends are examined that reveal a lot about the future.
The Miracle, Mandate and Mirage of High Performance Computing
Authors: Keyes David 
Published: June 2013

Abstract
High performance computing boasts a steadily increasing number of adherents, for excellent reasons, traditional and innovative. However, the promises for which scientists and engineers have been drawn to the extreme of the spectrum are more elusive than the simple extrapolation of decades of exponential improvement suggests. Programming today´s systems for high performance is already problematic for many scientists and the learning curve will inexorably steepen. Expectations should be brought in line with the increasing difficulty of pushing the high performance frontier, and, for once, the modeling, algorithms, and software advances required to use the emerging hardware effectively should not be left until the hardware begins to arrive.
HPC in the Automotive Industry — Trends and Prospects
Authors: Gümbel Chrstoph 
Published: June 2013

Abstract
The beginnings of high-performance applications in motor vehicle development date back some 25 years. Today, virtual development has become a permanent feature of the vehicle development process. Applications with high computation time requirements, such as aerodynamics, crash safety or the combustion process require the use of high performance computers. Increasing requirements placed on motor vehicles, especially with regard to safety, lightweight construction and emissions, taking into account economic, market and competitive factors, have resulted in the increasing use of HPC applications. Currently, it can be observed that HPC requirements are doubling every 14 to 16 months. In addition to conventional structural mechanics, growth drivers here include new material and joining technologies, fluid dynamics applications, as well as robustness evaluations, optimisation processes and multi-disciplinary simulations.

Abstract
In this study, the 166Ho-triethylene tetramine hexa (methylene phosphonic acid) (166Ho-TTHMP) complex was prepared as a bone palliation agent. The complex was successfully prepared using an in-house synthesized TTHMP ligand and [166Ho]HoCl3. Ho-166 chloride was obtained by thermal neutron irradiation (1×1013 n cm−2 s−1) of natural Ho(NO3)3 samples, followed by radiolabeling and stability studies. Biodistribution studies were also performed in wild type rats. The complex was prepared with the specific activity of 3–5 GBq/mg and a high radiochemical purity > 99%, (checked by ITLC). The 166Ho-TTHMP complex was stable in the final preparation and in the presence of human serum (> 90%) up to 72 h. The biodistribution of 166Ho-TTHMP in wild-type rats demonstrated significant bone uptake compared to 166HoCl3 up to 48 h. SPECT imaging of the radiolabeled compound was demonstrated to be in complete accordance with the biodistribution data. The major uptake was observed for long bones including thigh bones as well as skull and also knee and vertebrae. Primary properties of 166Ho-TTHMP demonstrate that this new therapeutic agent can be a good choice for metastatic bone pains.
241Pu concentrations in water, plankton and fish from the southern Baltic Sea
Authors: Strumińska-Parulska D. I. , Skwarzec Bogdan 
Published: June 2013

Abstract
The aim of the work was to determine 241Pu activities in different components (water, plankton and fish) of the southern Baltic Sea ecosystem. Measurement of 241Pu in the samples was done indirectly by determining the increment in 241Am from the decay of the β-emitting 241Pu in samples collected 10–15 years after the Chernobyl accident.
Enhanced levels of 241Pu were observed in all analyzed Baltic samples. The highest 241Pu concentrations in fish were found in Perciformes: benthic round goby (0.863 ± 0.066 mBq/g ww) and pelagic perch (0.666 ± 0.001 mBq/g ww). Plutonium is also non-uniformly distributed in the organs and tissues of the analyzed fish; especially pelagic herring and cod as well as benthic flounder. Most of 241Pu in flounder, herring and cod is located in soft tissues, especially digestive organs (stomach, intestine, liver). The annual individual effective doses calculated on the basis of 241Pu concentrations in fish indicated that the impact of the consumption of 241Pu containing Baltic fish on the annual effective dose for a statistical inhabitant of Poland was very small.

Published: June 2013

ABSTRACT

Objective:
To evaluate the dentofacial effects of the Forsus Fatigue Resistant Device (FRD) used with miniscrew anchorage (FRDMS) and compare them with those of conventional FRD and an untreated Class II control group.

Materials and Methods:
The sample consisted of 48 Class II subjects. Sixteen patients (13.68 ± 1.09 years of age) were treated with FRDMS, whereas 17 subjects (14.64 ± 1.56 years of age) were treated with only FRD. Also, a control sample of 15 untreated Class II subjects (14.13 ± 1.50 years of age) was constructed. Angular and linear measurements were made on 96 lateral cephalograms. Paired t, one-way analysis of variance, and Tukey tests were used for statistical analysis.

Results:
Class I molar relationship and overjet correction were achieved in an average period of 6.5 ± 1.97 and 5.5 ± 1.80 months in the FRDMS and FRD groups, respectively. No skeletal effect was determined in both treatment groups. Greater overbite correction was found in the FRD group. Retrusion and extrusion of maxillary incisors, distalization of maxillary molars, and extrusion of mandibular molars were significant in both treatment groups. Labial tipping of mandibular incisors was significantly greater in the FRD group than in the FRDMS group.

Conclusion:
Overjet and molar correction was totally dentoalveolar. Unfavorable labial tipping of mandibular incisors was effectively minimized with the usage of miniscrews.
Preventing circulating fluidised bed agglomeration and deposition during biomass combustion
Authors: Dunajski Łukasz , Kruk Wojciech , Nowak Wojciech 
Published: June 2013

Abstract
According to a fuel flexibility, fluidized bed boilers are considered as appropriate for biomass combustion as cofiring. But the burning of fuels such as forest and agricultural biomass raises a number of operational problems. Most important of these problems are bed agglomeration and deposition. Deposition appears when biomass contains significant amounts of alkali elements, such as sodium and potassium. The purpose of the work is to select a fuel additive to overcome these operational problems. Investigations were conducted in two stages at a pilot scale 0.1 MWth laboratory circulating fluidized bed reactor. As the fuel, the mixture of biomass contained forest residues, sunflower husks, straw and wood pellets from mixed woods was selected. In the first stage biomass was burnt without any additives, while in the second one the fuel was enriched with some additive. The additive (liquid mixture of chemicals) was added to the fuel in amounts of 1 dm3 per 5-10 Mg of fuel. The following operational parameters were examined: temperature profiles along the height of the circulating fluidised bed column, pressure profiles, emissions. After the tests, the laboratory reactor was inspected inside. Its results enables expression of the following conclusions: there was no agglomeration during fuel additive testing, and the deposition was reduced as well. Moreover, the parts (heating surfaces, separator) of the laboratory reactor were coated with a protective layer. The layer covered microcracks and protected the parts from deposition for a long period after the operation.

The thermal energy contained in water vapour and hot water will be utilized in producing, in combination, of electrical energy, and for heating of cubature objects. Modern alternative fuels in the form of briquettes and pellets will be produced from hard coals and municipal waste other than hazardous. There have been presented the properties of alternative fuels obtained, and the concept of their utilization in the process of energy production in cogeneration.
Analysis of the occurrence of natural convection in a bed of bars in vertical temperature gradient conditions
Authors: Wyczółkowski Rafał , Musiał Dorota 
Published: June 2013

Abstract
The reason for undertaking this study was to determine the possible involvement of natural convection in the global heat transfer, that occurs in the heated steel rods bed. This problem is related to the setting of the effective thermal conductivity of the bars bed. This value is one of the boundary conditions for heating modeling of steel rods bundles during heat treatment. The aim of this study was to determine for which geometry of the bed bars, there will be no free convection. To analyze the problem the Rayleigh criterion was used. It was assumed that for the value of the number Ra < 1700 convection in the bed bars does not occur. For analysis, the results of measurements of the temperature distribution in the unidirectionally heated beds of bars were used. It has been shown, that for obtained, during the test, differences of temperature between the surfaces of adjacent rods, convection can occur only when the diameter of the rod exceeds 18 mm.
Educational and Psychological Aspects of Environmental Awareness and a Sense of Belonging
Authors: Rode Ojārs 
Published: June 2013

Abstract
The research problem concerns the sphere of relationships with the environment and an individual's awareness in the aspect of satisfying the need for belonging. This research aims to determine the conditions of relationships with the environment and an individual's awareness in the process of personality formation. The research is constituted by an analysis of literary sources in education, psychology, philosophy and folklore studies as well as by a study of the formation process of a sense of belonging in Latvian folk songs or dainas. This research shows that a sense of belonging is associated with harmony between an individual and the surrounding environment. It is developed in the space of conditions for an individual's self-realisation that balances individual and social interests. For the development of inborn gifts, a natural environment of upbringing is needed. For the development of a sustainable education model in Latvia, the ideas found in Latvian dainas that have ascertained their sustainability may be of importance.

Authors: Strode Aina 
Published: June 2013

Abstract
Implementation of participatory action research during pedagogical practice facilitates sustainable education because its objective is to understand professional practice, enrich the capacity of involved participants and an opportunity to make inquiries for the improvement of quality. In the research of professional practice, subjects explore themselves; research is critically informative, active and action-oriented. Basing on the analysis of the prospective teachers' professional independence formation during pedagogical practice, the conditions for the individual's sustainable professional development are updated, the principles of organising pedagogical practice are determined. The experts' opinion method was applied in the evaluation of the developed practice model. Four experts from four Latvian universities were involved in the questionnaire; the content analysis of expert opinions was performed. As a result, the opportunities of the developed model to ensure sustainable education as well as its strengths and weaknesses were determined. Activation of the holistic and action approaches to develop students' independent professional activity and ensure sustainable education, cooperation context, targeted planning of the student-centred process, orientation to students' self-experience, respect of research aspects were completely appreciated.
Sustainable Development and ICT in Slovenian Primary and Secondary Schools: Media-Ecological Perspective
Authors: Zakrajšek Srečko , Purg Peter 
Published: June 2013

Abstract
The goal of the research was to get an overview on the possibilities of sustainable development in relation to information and communication technologies in primary and secondary schools in Slovenia from the perspective of media ecology. The study analyses the reasons for a reorientation of the educational system and new programmes towards sustainability and relates these developments to the activities of Eco-schools in Slovenia. The findings show that the guidelines of sustainable development are included in the programmes, yet they do not encompass the possibilities opening up by new technologies. Contemporary teaching methods are not widespread due to the inadequate education and training of teachers. At the same time, numerous problems arising from the introduction of new technologies and equipment into schools are neither anticipated nor tackled in the renewed curricula, thus failing to integrate a contemporary media-ecological perspective. Judging from the roadmap documents, even after the renewal process will have been finished, the situation will hardly change unless major changes are introduced into the planned concept of renovation and additional investments of funds for equipment, the preparation of materials and, above all, teacher education are secured.
Perceptions of Research in Education for Sustainable Development: An International Perspective
Authors: Pipere Anita , Reunamo Jyrki , Jones Marion 
Published: June 2013

Abstract
This paper reports on a study undertaken to investigate international perspectives of what constitutes research in education for sustainable development (ESD). By employing inductive thematic content analysis, the authors sought to examine the perceptions of 66 ESD researchers from 19 countries. The findings reveal a concern with the methodological aspects of research and an emergent need for synergy between the methodology of educational research and specific themes relevant to ESD research. The significant overlap of themes and aspects of ESD research apparent across the different contexts within which the researchers were embedded indicates a unified core of ESD research, although there is also evidence of contextual factors influencing the research agenda. Based on the findings of this study, the paper concludes that there is an overlap between educational research and ESD research, but that the latter has its own specific aims, themes and political supporters. In an endeavour to develop a shared understanding about ESD research across disciplines and research context, a common language has to be developed to facilitate a constructive dialogue and research capacity building in this novel field.

Published: June 2013

Abstract
This study dwells upon communicative approach as a tool for relating reading and writing skills in early childhood education in a developing economy. The quantitative data was gathered through the use of structured questionnaires and was analysed using SPSS version 17. This study confirms that teachers in the selected early childhood education centres (ECEC) have no professional early childhood education qualifications and, as a result, are not qualified to effectively carry out their teaching responsibilities. It is hoped that this study can contribute to a deeper understanding of how early childhood education teachers perceive language teaching and consequently assist in the development of teacher education programmes and activities. Teacher training and education courses must play a more active role in informing trainee teachers of the instructional value of communicative approach in the teaching and learning of the English language. This study provides parents, teachers, researchers, the public and those who manage education systems with new data that will help them to answer questions about the failing state of education in Nigeria.

Authors: Świtała Eugeniusz 
Published: June 2013

Abstract
This paper reports on a fragment of a broader research on values education in Polish and Latvian schools. This paper seeks to evaluate data from the European Social Survey (ESS) and elaborate on the frames of references for identification of the aims for future research. The paper highlights the findings of an action research carried out in two Polish schools. The values of European countries are analysed in the context of educational research in Europe and other regions of the world. The frames of references constructed during the study and data from European Social Survey were the grounds for creating a questionnaire for an action research to find out the tendencies that derive from the experience of students. The survey was preceded by a special training session for the teaching staff about evaluation and its significance for increasing the quality of school performance.
