Move it, use it : university-school collaboration for learning to teach physical education in primary schools

Reports of increasing numbers of obese Australian children and adolescents have raised the alarm to be proactive in reducing this so called epidemic. It has evoked a call for greater emphasis on teaching physical education in schools, as a measure for attaining fitness not only with obese students but for all students. This paper emphasises how preservice teachers need to be a key target for implementing physical education (PE) reform in schools, as many primary teachers will be generalists and may not be confident enough to implement PE effectively. Through a review of existing literature, teaching practices essential for the effective promotion and implementation of PE were identified under six broad categories: personal-professional skills development, addressing system requirements, pedagogical practices, managing student behaviour, providing feedback to students, and reflecting on practice. Subsequently, the development of these practices in preservice teachers is considered in the context of a university-school collaboration where preservice teachers taught physical education to primary school students for one day per week over a four week period. These authentic teaching experiences provided the preservice teachers with vital opportunities to put theory into practice and interact with “real-world” students. Self-evaluative data from 38 of these preservice teachers, in the form of a five-part Likert scale survey and extended response survey, demonstrated that they were able to develop the majority of the essential teaching practices identified by literature. In particular, the preservice teachers developed self efficacy, enthusiasm, and motivation for teaching PE, facets which are often found to be lacking in generalist primary teachers and yet are essential if children’s perceptions and habits regarding physical activity are to be changed.

Pool it, share it, use it: the European Council on defence. Security Policy Brief No. 44, March 2013

Three major geopolitical events are putting the stability of the Eastern Mediterranean at risk. Most of the region is in a deep monetary and economic crisis. The Arab Spring is causing turmoil in the Levant and the Maghreb. Gas and oil discoveries, if not well managed, could further destabilise the region. At the same time, Russia and Turkey are staging a comeback. In the face of these challenges, the EU approaches the Greek sovereign debt crisis nearly exclusively from a financial and economic viewpoint. This brief argues that the EU has to develop a comprehensive strategy for the region, complementing its existing multilateral regional framework with bilateral agreements in order to secure its interests in the Eastern Mediterranean.

Automatic post-adoptive information technology use: The role of innovativeness goal

The business value of information technology (IT) is realized through the continuous use of IT subsequent to users’ adoption. Understanding post-adoptive IT usage is useful in realizing potential IT business value. Most previous research on post-adoptive IT usage, however, dismisses the unintentional and unconscious aspects of usage behavior. This paper advances understanding of the unintentional, unconscious, and thereby automatic usage of IT features during the post-adoptive stage. Drawing from Social Psychology literature, we argue human behaviors can be triggered by environmental cues and directed by the person’s mental goals, thereby operating without a person’s consciousness and intentional will. On this basis, we theorize the role of a user’s innovativeness goal, as the desired state of an act to innovate, in directing the user’s unintentional, unconscious, and automatic post-adoptive IT feature usage behavior. To test the hypothesized mechanisms, a human experiment employing a priming technique, is described.

Examining preservice teachers’ applied learning experiences in the Teacher Education Done Differently (TEDD) project

Reviews have criticised universities for not embedding sufficient praxis for preparing preservice teachers for the profession. The Teacher Education Done Differently (TEDD) project explored praxis development for preservice teachers within existing university coursework. This mixed-method investigation involved an analysis of multiple case studies with preservice teacher involvement in university programs, namely: Ed Start for practicum I (n=26), III (n=23), and IV (n=12); Move It Use It (Health and Physical Education program; n=38), Studies of Society and its Environment (SOSE, n=24), and Science in Schools (n=38). The project included preservice teachers teaching primary students at the campus site in gifted education (the B-GR8 program, n=22). The percentage range for preservice teacher agreement of their praxis development leading up to practicum I, III, and IV was between 91-100% with a high mean score range (4.26-5.00). Other university units had similar findings except for SOSE (i.e., percentage range: 10-86%; M range: 2.33-4.00; SD range: 0.55-1.32). Qualitative data presented an understanding of the praxis development leading to the conclusion that additional applied learning experiences as lead-up days for field experiences and as avenues for exploring the teaching of specific subject areas presented opportunities for enhancing praxis.

Towards a multiple-goal pursuit and multilevel view of continuing information technology usage : a process model integration and a research agenda

The value of information technology (IT) is often realized when continuously being used after users’ initial acceptance. However, previous research on continuing IT usage is limited for dismissing the importance of mental goals in directing users’ behaviors and for inadequately accommodating the group context of users. This in-progress paper offers a synthesis of several literature to conceptualize continuing IT usage as multilevel constructs and to view IT usage behavior as directed and energized by a set of mental goals. Drawing from the self-regulation theory in the social psychology, this paper proposes a process model, positioning continuing IT usage as multiple-goal pursuit. An agent-based modeling approach is suggested to further explore causal and analytical implications of the proposed process model.

Adoption processes for EDM, EDI and BIM technologies in the construction industry

Three strategically important uses of IT in the construction industry are the storage and management of project documents on webservers (EDM), the electronic handling of orders and invoices between companies (EDI) and the use of 3-D models including non-geometrical attributes for integrated design and construction (BIM). In a broad longitudinal survey study of IT use in the Swedish Construction Industry the extent of use of these techniques was measured in 1998, 2000 and 2007. The results showed that EDM and EDI are currently already well-established techniques whereas BIM, although it promises the biggest potential benefits to the industry, only seems to be at the beginning of adoption. In a follow-up to the quantitative studies, the factors affecting the decisions to implement EDM, EDI and BIM as well as the actual adoption processes, were studied using semi-structured interviews with practitioners. The theoretical basis for the interview studies was informed by theoretical frameworks from IT-adoption theory, where in particular the UTAUT model has provided the main basis for the analyses presented here. The results showed that the decisions to take the above technologies into use are made on three differ- ent levels: the individual level, the organizational level in the form of a company, and the organiza- tional level in the form of a project. The different patterns in adoption can to some part be explained by where the decisions are mainly taken. EDM is driven from the organisation/project level, EDI mainly from the organisation/company level, and BIM is driven by individuals pioneering the technique.

Information Technology in Construction – Domain Definition and Research Issues

This article discusses the scope of research on the application of information technology in construction (ITC). A model of the information and material activities which together constitute the construction process is presented, using the IDEF0 activity modelling methodology. Information technology is defined to include all kinds of technology used for the storage, transfer and manipulation of information, thus also including devices such as copying machines, faxes and mobile phones. Using the model the domain of ITC research is defined as the use of information technology to facilitate and re-engineer the information process component of construction. Developments during the last decades in IT use in construction is discussed against a background of a simplified model of generic information processing tasks. The scope of ITC is compared with the scopes of research in related areas such as design methodology, construction management and facilities management. Health care is proposed as an interesting alternative (to the often used car manufacturing industry), as an IT application domain to compare with. Some of the key areas of ITC research in recent years; expert systems, company IT strategies, and product modelling are shortly discussed. The article finishes with a short discussion of the problems of applying standard scientific methodology in ITC research, in particular in product model research.

ICT and the Shaping of Society: Exploring Human -ICT Relationships in Everyday Life (summary section only)

This thesis explores the relationship between humans and ICTs (information and communication technologies). As ICTs are increasingly penetrating all spheres of social life, their role as mediators – between people, between people and information, and even between people and the natural world – is expanding, and they are increasingly shaping social life. Yet, we still know little of how our life is affected by their growing role. Our understanding of the actors and forces driving the accelerating adoption of new ICTs in all areas of life is also fairly limited. This thesis addresses these problems by interpretively exploring the link between ICTs and the shaping of society at home, in the office, and in the community. The thesis builds on empirical material gathered in three research projects, presented in four separate essays. The first project explores computerized office work through a case study. The second is a regional development project aiming at increasing ICT knowledge and use in 50 small-town families. In the third, the second project is compared to three other longitudinal development projects funded by the European Union. Using theories that consider the human-ICT relationship as intertwined, the thesis provides a multifaceted description of life with ICTs in contemporary information society. By oscillating between empirical and theoretical investigations and balancing between determinist and constructivist conceptualisations of the human-ICT relationship, I construct a dialectical theoretical framework that can be used for studying socio-technical contexts in society. This framework helps us see how societal change stems from the complex social processes that surround routine everyday actions. For example, interacting with and through ICTs may change individuals’ perceptions of time and space, social roles, and the proper ways to communicate – changes which at some point in time result in societal change in terms of, for example, new ways of acting and knowing things.

Pedagozinando em sala de aula: artes de dizer e pedagogias de fazer

Redesenham-se artes de dizer em um papel xerocado, artes que se traduzem em traços, rabiscos, versos, gritos, modos de fazer. Fanzine é assim, mais do que uma revista de papel sulfite, um espaço recortado, colado para produção de saberes ou, se preferir, uma revista independente na tela do computador. Este trabalho, portanto, propõe um mergulho entre a linha do underground e da pedagogia de criação de fanzines em sala de aula. Compreender os usos e as artes de dizer significa entender historicamente o que as publicações não-oficiais representam para a contemporaneidade. Desta forma, a lógica dos fanzines é bem mais do que trafegar em um circuito alternativo, define-se por si só como uma forma independente de fazer uso de uma expressão. Assim, o fazer fanzine como filofanzine de vida é um exemplo de que esta forma de expressão ultrapassa as paredes institucionais.

基于结构分析地震资料去噪方法研究

With the development of oil and gas exploration, the exploration of the continental oil and gas turns into the exploration of the subtle oil and gas reservoirs from the structural oil and gas reservoirs in China. The reserves of the found subtle oil and gas reservoirs account for more than 60 percent of the in the discovered oil and gas reserves. Exploration of the subtle oil and gas reservoirs is becoming more and more important and can be taken as the main orientation for the increase of the oil and gas reserves. The characteristics of the continental sedimentary facies determine the complexities of the lithological exploration. Most of the continental rift basins in East China have entered exploration stages of medium and high maturity. Although the quality of the seismic data is relatively good, this areas have the characteristics of the thin sand thickness, small faults, small range of the stratum. It requests that the seismic data have high resolution. It is a important task how to improve the signal/noise ratio of the high frequency of seismic data. In West China, there are the complex landforms, the deep embedding the targets of the prospecting, the complex geological constructs, many ruptures, small range of the traps, the low rock properties, many high pressure stratums and difficulties of boring well. Those represent low signal/noise ratio and complex kinds of noise in the seismic records. This needs to develop the method and technique of the noise attenuation in the data acquisition and processing. So that, oil and gas explorations need the high resolution technique of the geophysics in order to solve the implementation of the oil resources strategy for keep oil production and reserves stable in Ease China and developing the crude production and reserves in West China. High signal/noise ratio of seismic data is the basis. It is impossible to realize for the high resolution and high fidelity without the high signal/noise ratio. We play emphasis on many researches based on the structure analysis for improving signal/noise ratio of the complex areas. Several methods are put forward for noise attenuation to truly reflect the geological features. Those can reflect the geological structures, keep the edges of geological construction and improve the identifications of the oil and gas traps. The ideas of emphasize the foundation, give prominence to innovate, and pay attention to application runs through the paper. The dip-scanning method as the center of the scanned point inevitably blurs the edges of geological features, such as fault and fractures. We develop the new dip scanning method in the shap of end with two sides scanning to solve this problem. We bring forward the methods of signal estimation with the coherence, seismic wave characteristc with coherence, the most homogeneous dip-sanning for the noise attenuation using the new dip-scanning method. They can keep the geological characters, suppress the random noise and improve the s/n ratio and resolution. The rutine dip-scanning is in the time-space domain. Anew method of dip-scanning in the frequency-wavenumber domain for the noise attenuation is put forward. It use the quality of distinguishing between different dip events of the reflection in f-k domain. It can reduce the noise and gain the dip information. We describe a methodology for studying and developing filtering methods based on differential equations. It transforms the filtering equations in the frequency domain or the f-k domain into time or time-space domains, and uses a finite-difference algorithm to solve these equations. This method does not require that seismic data be stationary, so their parameters can vary at every temporal and spatial point. That enhances the adaptability of the filter. It is computationally efficient. We put forward a method of matching pursuits for the noise suppression. This method decomposes any signal into a linear expansion of waveforms that are selected from a redundant dictionary of functions. These waveforms are chosen in order to best match the signal structures. It can extract the effective signal from the noisy signal and reduce the noise. We introduce the beamforming filtering method for the noise elimination. Real seismic data processing shows that it is effective in attenuating multiples and internal multiples. The s/n ratio and resolution are improved. The effective signals have the high fidelity. Through calculating in the theoretic model and applying it to the real seismic data processing, it is proved that the methods in this paper can effectively suppress the random noise, eliminate the cohence noise, and improve the resolution of the seismic data. Their practicability is very better. And the effect is very obvious.

Analysis of EnterpriseVoIP Traffic from aWire line IMS System

With the rapid development of telecommunication industry, the IP multimedia Subsystem (IMS) could very well be the panacea for most telecom operators. It is originally defined as the core network for 3G mobile systems by the 3rd Generation Partnership Project (3GPP), the more recent development is merging between fixed line network and wireless networkd This report researchs the characteristic of the IMS data and proposes an IMS characterization analysis. We captured the IMS traffic data with 10 tousands users for about 41 hours. By analyzing the characteristics of the IMS, we know that the most important application in the IMS is VoIP call. Then we use the tool designed by Tsinghua University & Ericsson Company to recognize the data, and the results we got can be used to build the traffic models. From the results of the traffic models, I will get some reasons and conclusion. The traffic model gives out the types of session and types of VoIP call. I bring into a concept—busy hour. This concept is very important because it can help us to know which period is the peak of the VoIP call. The busy hour is from 10:00 to 11:00 in the morning. I also bring into another concept—connection ratio. This concept is significant because it can evaluate whether the VoIP call is good when it use IMS network. By comparing the traffic model with other one’s models, we found the different results from them, both the accuracy and the busy hour. From the contract, we got the advantages of our traffic models.

Spanning Tree Approach On The Snow Cleaning Problem

Snow cleaning is one of the important tasks in the winter time in Sweden. Every year government spends huge amount money for snow cleaning purpose. In this thesis we generate a shortest road network of the city and put the depots in different place of the city for snow cleaning. We generate shortest road network using minimum spanning tree algorithm and find the depots position using greedy heuristic. When snow is falling, vehicles start work from the depots and clean the snow all the road network of the city. We generate two types of model. Models are economic model and efficient model. Economic model provide good economical solution of the problem and it use less number of vehicles. Efficient model generate good efficient solution and it take less amount of time to clean the entire road network.
