Technology adoption : voices of teaching academics, educational designers and students

This folio presents three studies (a dissertation and two electives) which use qualitative case study methodologies to investigate technology adoption from three perspectives. Central to all three studies is the study context of Monash University. The Dissertation explores adoption of web-based learning and teaching approaches from the perspective of teaching academics as they incorporate these to facilitate their students’ learning. The study investigates teaching academics’ reasons for adopting these new technologies, the factors that influenced their adoption decisions, and the challenges they were confronted with, including the contributing factors that impacted on their adoption decisions. The study shows that while contextual factors such as power and politics of the school, department, faculty and the institution impact on adoption, supportive organisational infrastructures and policy frameworks are necessary to encourage adoption, including wider adoption. In turn, on going staff development, adoption of new work practices and being adaptive to changing work environments are key demands made on teaching academics as a result of adopting web-based teaching approaches. Elective 1, a smaller study, leads on from the dissertation and examines the impact of technology adoption on the evolving role of educational designers. The study identifies the educational designers’ role change in assisting teaching academics to move from more conventional forms of teaching to more technology based learner-centred collaborative models. An important aspect of the study is the managers’ perspectives of this role in a university that has adopted a strong flexible learning and technology policy. The findings show that educational designers now work as project managers in larger teams consisting of a wider range of professionals, their expanded role in introducing technology into learning designs, providing staff development in the area, and giving technical help including advice on copyright and intellectual property issues. Elective 2 explores student readiness to adopt these technologies for learning. The study is designed to achieve an understanding of three broad categories of learners from a first year design unit: (1) South East Asian and East Asian students, (2) all other international students, and (3) local Australian students are studied to examine their readiness for modes of learning that are flexible; their approaches to study in a creative discipline area; and their openness to using technology. Findings of the study are discussed under the key themes – dependence on the teacher and classroom environment, flexible learning and working alone, structure, communication and work patterns. The study concludes by discussing the possible cultural attributes that have an impact on the learning. The three studies found that the institution, its people, structures and processes must all adapt, evolve and grow in order to provide effective, engaging, student-centred web-based learning environments. Students in turn must be enabled to manage their study, make use of the technologies and maximise their learning experience. The findings revealed the stage of technology use reached at Monash University at the time of the study through the voices of the teaching academics, educational designers and students.

Telecommunication technology and the professional development of teachers : challenge and opportunity

The thesis explores an effective model for using the internet in a distance training program for secondary school teachers. The professional development program, the dissertation, titled The Virtual University: Professional development for teachers, was initiated based on aspects of telecommunication technology and the professional development for Thai school teachers. The question of this program was “How could information technology be used in developing an appropriate professional development model for Thai teachers?” Prior to the project, the four research studies were conducted to formulate the related base line information and supported framework for the program development. The four researches are: (1) Telecommunication Technology in Thai Schools, (2) The Role of University on Science Teachers Development, (3) Computer Education Curriculum for Student Teachers: Theory and Practice, and (4) Teachers’ Perceptions of the Academic Link Project Between Schools and Universities for Teacher Professional Development. The first research study provides the information about the necessary basic factors for change in Thai secondary schools and the new insights and understandings about change in Thai schooling. The major findings were the understandings about teachers’ need for professional development, the available support in Thai school for professional development, and the limitations of professional development of teachers. The second research study provides the information about the roles of university faculty on initiation and operation of science teacher development programs, science teaching and learning resources centers, science instructional media design and production services, science teaching clinics, and science teachers’ associations. The third research study provides the conceptual framework for both preservice and inservice curriculum development program for teacher development. The last research study provides a base of descriptive information about the perspectives of school teachers towards the academic link project between schools and universities and the partnership which can assist in its establishment. The findings of these four research tasks were used for the formation of the framework of the dissertation. The EDNET Project, an example of teachers’ professional development through the information technology based training, was developed and implemented with ten school teachers in Khon Kaen.

The challenges of cloud computing technology adoption in e-government

 The endless transformation of technological innovation requires greater collaboration of Information Communication and Technology (ICT) in various areas especially in public sectors. Many attempts have been made in improving the quality of E-Government services; one of it is adopting the cloud computing technology. Successful implementation of cloud computing technology can benefit the public sector in many ways one of it is cost reduction. Most government organizations especially in the developing countries are committed in adopting the cloud technology based on the increased demands in cloud adoption in E Government services. Unfortunately, despite all the benefits, the cloud computing technology raises some major risks. The success of implementation of cloud computing technology is determined by how well the government tackles the challenges. Therefore, this paper specifically surveyed the associated challenges of adopting Cloud Technology for E-Government by choosing Malaysia as the case study.

A qualitative study of the internationalization of born-global technology start-ups in Brazil

O fenômeno das empresas born globals e a internacionalização de empresas brasileiras de base tecnológica são tópicos recentes na literatura acadêmica, devido também ao fenômeno ser recente.

Esse estudo, entretanto, tem como objetivo analisar startups de maneira qualitativa. Uma extensa revisão de literatura foi desenvolvida a fim de melhor analisar as fundações nas quais o estudo seria desenvolvido, revisando os métodos de internacionalização, empreendedorismo no Brasil, e o fenômeno born global no geral. Entrevistas foram conduzidas com empreendedores no Brasil, que passaram pelo processo de internacionalização de seus modelos de negócios, a fim de reunir introspecções a respeito das peculiaridades do mercado brasileiro. Foram também analisados os fatores de escalabilidade de modelos de negócios dependentes de tecnologia, motivadores para a internacionalização, critério de seleção de mercados, programas governamentais, e o papel das startups brasileiras em uma perspectiva global.

Modelo institucional do processo de estruturação de empresas de desenvolvimento de software: um estudo de múltiplos casos

Some authors have shown the need of understanding the technological structuring process in contemporary firms. From this perspective, the software industry is a very important element because it provides products and services directly to many organizations from many fields. In this case, the Brazilian software industry has some peculiarities that distinguish it from other industries located in developed countries, which makes its understanding even more relevant. There is evidence that local firms take different strategies and structural configurations to enter into a market naturally dominated by large multinational firms. Therefore, this study aims to understand not only the structural configurations assumed by domestic firms but also the dynamic and the process that lead to these different configurations. To do so, this PhD dissertation investigates the institutional environment, its entities and the isomorphic movements, by employing an exploratory, descriptive and explanatory multiple cases study. Eight software development companies from the Recife's information technology Cluster were visited. Also, a form was applied and an interview with one of the main firm s professional was conducted. Although the study is predominantly qualitative, part of the data was analyzed through charts and graphs, providing a companies and environment overview that was very useful to analysis done through the interviews interpretation. As a result, it was realized that companies are structured around hybrids business models from two ideal types of software development companies, which are: software factory and technology-based company. Regarding the development process, it was found that there is a balanced distribution between the traditional and agile development paradigm. Among the traditional methodologies, the Rational Unified Process (RUP) is predominant. The Scrum is the most used methodology among the organizations based on the Agile Manifesto's principles. Regarding the structuring process, each institutional entity acts in such way that generates different isomorphic pressure. Emphasis was given to entities such as customers, research agencies, clusters, market-leading businesses, public universities, incubators, software industry organizations, technology vendors, development tool suppliers and manager s school and background because they relate themselves in a close way with the software firms. About this relationship, a dual and bilateral influence was found. Finally, the structuring level of the organizational field has been also identified as low, which gives a chance to organizational actors of acting independently

Planejamento estratégico e operacional na pequena empresa: impactos da formalização no desempenho e diferenças setoriais

This article analyzes the results of three different field research, carried out simultaneously in small technology-based sectors, metal-mechanical industry and hotel in the city of São Carlos - SP, with goals, concepts and methods of similar research. The studies were classified as quantitative and descriptive and conducted through a survey of opinion with the main leader of the company. It were considered valid for analyses, the responses of 57 leaders, it were 33 technology-based sector, 13 of the metal-mechanic industry and 11 in the hospitality sector. The main results: the formalization of planning has not led to better performance, considering the indicator growth in sales in the three sectors studied and that the degree of formalization of the planning of the companies in the technologybased sector was higher, while the hospitality sector had a percentage smaller. The dynamic aspect of technology-based sector and stability in the hotel sector in the region studied, leads to assume that the turbulence of the environment is a predominant factor, contradicting the proposal of some authors, in which the formal planning is inappropriate for small companies that operate in environments that change quickly.

Análise do crescimento das empresas de base tecnológica no Brasil

Technology-Based Firms (TBFs) are companies with intensive innovation dynamics based on technical competences, and for which high growth rates are expected. Nevertheless, even in developed countries, the evidence suggests that significantly high growth rates are more the exception than the rule. In Brazil, most studies on TBFs focus on factors that limit their success, such as managerial experience and capital availability. Based on extensive field research and on a reliable enterprise growth rate indicator, this article aims to evaluate the expansion of those firms, analyzing its relation to key elements such as degree of consolidation, market insertion, and public policy support. We found a growth rate which, although widely varied amongst firms, was significant and was not directly related to the amount of public policy support.

Optical Microring Resonators based on ion-implanted LiNbO3 ridge waveguides

The growing interest for Integrated Optics for sensing, telecommunications and even electronics is driving research to find solutions to the new challenges issued by a more and more fast, connected and smart world. This thesis deals with the design, the fabrication and the characterisation of the first prototypes of Microring Resonators realised using ion implanted Lithium Niobate (LiNbO3) ridge waveguides. Optical Resonator is one among the most important devices for all tasks described above. LiNbO3 is the substrate commonly used to fabricate optical modulators thanks to its electro-optic characteristics. Since it is produced in high quantity, good quality and large wafers its price is low compared to other electro-optic substrate. We propose to use ion implantation as fabrication technology because in the other way standard optical waveguides realised in LiNbO3 by Proton Exchange (PE) or metal diffusion do not allow small bending radii, which are necessary to keep the circuit footprint small. We will show in fact that this approach allows to fabricate waveguides on Lithium Niobate that are better than PE or metal diffused waveguides as it allows smaller size devices and tailoring of the refractive index profile controlling the implantation parameters. Moreover, we will show that the ridge technology based on enhanced etching rate via ion implantation produces a waveguide with roughness lower than a dry etched one. Finally it has been assessed a complete technological process for fabrication of Microring Resonator devices in Lithium Niobate by ion implantation and the first prototypes have been produced.

Streaming Support for Data Intensive Cloud-Based Sequence Analysis

Cloud computing provides a promising solution to the genomics data deluge problem resulting from the advent of next-generation sequencing (NGS) technology. Based on the concepts of “resources-on-demand” and “pay-as-you-go”, scientists with no or limited infrastructure can have access to scalable and cost-effective computational resources. However, the large size of NGS data causes a significant data transfer latency from the client’s site to the cloud, which presents a bottleneck for using cloud computing services. In this paper, we provide a streaming-based scheme to overcome this problem, where the NGS data is processed while being transferred to the cloud. Our scheme targets the wide class of NGS data analysis tasks, where the NGS sequences can be processed independently from one another. We also provide the elastream package that supports the use of this scheme with individual analysis programs or with workflow systems. Experiments presented in this paper show that our solution mitigates the effect of data transfer latency and saves both time and cost of computation.

WiMAX,Technology and Market.

Wireless communication is the transfer of information from one place to another without using wires. From the earliest times, humans have felt the need to develop techniques of remote communication. From this need arose the smoke signals, communication by sun reflection in mirrors and so on. But today the telecommunications electronic devices such as telephone, television, radio or computer. Radio and television are used for one-way communication. Telephone and computer are used for two-way communication. In wireless networks there is almost unlimited mobility, we can access the network almost anywhere or anytime. In wired networks we have the restriction of using the services in fixed area services. The demand of the wireless is increasing very fast; everybody wants broadband services anywhere anytime. WiMAX (Worldwide Interoperability for Microwave Access) is a broadband wireless technology based on IEEE 802.16-2004 and IEEE 802.16e-2005 that appears to solve this demand. WIMAX is a system that allows wireless data transmission in areas of up to 48 km of radius. It is designed as a wireless alternative to ADSL and a way to connect nodes in wireless metropolitan areas network. Unlike wireless systems that are limited in most cases, about 100 meter, providing greater coverage and more bandwidth. WIMAX promises to achieve high data transmission rates over large areas with a great amount of users. This alternative to the networks of broadband access common as DSL o Wi-Fi, can give broadband access to places quickly to rural areas and developing areas around the world. This paper is a study of WIMAX technology and market situation. First, the paper is responsible for explaining the technical aspects of WIMAX. For this gives an overview of WIMAX standards, physical layer, MAC layer and WiMAX, Technology and Market Beijing University of Post and Telecommunications 2 WIMAX network architecture. Second, the paper address the issue of market in which provides an overview of development and deployment of WIMAX to end the future development trend of WIMAX is addressed. RESUMEN: Por comunicaciones inalámbricas se entiende la transferencia de información desde un lugar a otro sin la necesidad de un soporte físico como es por ejemplo el cable. Por lo que remontándose a los principios de la existencia del ser humano, nos damos cuenta de que el ser humano siempre ha sentido la necesidad de desarrollar técnicas para lograr comunicarse a distancia con sus semejantes. De dicha necesidad, surgieron técnicas tan ancestrales como puede ser la comunicación mediante señales de humo o por reflexión de los rayos solares en espejos entre otras. La curiosidad del ser humano y la necesidad de comunicarse a distancia fue la que llevó a Alexander Graham Bell a inventar el teléfono en 1876. La aparición de un dispositivo que permitía comunicarse a distancia permitiendo escuchar la voz de aquella persona con la que se quería hablar, supuso una revolución no solo en el panorama tecnológico, si no también en el panorama social. Pues a parte de permitir comunicaciones a larga distancia, solventó el problema de la comunicación en “tiempo real”. A raíz de este invento, la tecnología en materia de comunicación ha ido avanzando significativamente, más concretamente en lo referido a las comunicaciones inalámbricas. En 1973 se realizó la primera llamada desde un terminal móvil aunque no fue hasta 1983 cuando se empezó a comercializar dicho terminal, lo que supuso un cambio de hábitos y costumbres para la sociedad. Desde la aparición del primer móvil el crecimiento del mercado ha sido exponencial, lo que ha repercutido en una demanda impensable de nuevas aplicaciones integradas en dichos dispositivos móviles que satisfagan las necesidades que día a día autogenera la sociedad. Tras conseguir realizar llamadas a larga distancia de forma inalámbrica, el siguiente paso fue la creación de los SMS (Short Message System) lo que supuso una nueva revolución además de abaratar costes al usuario a la hora de comunicarse. Pero el gran reto para la industria de las comunicaciones móviles surgió con la aparición de internet. Todo el mundo sentía la necesidad de poder conectarse a esa gran base de datos que es internet en cualquier parte y en cualquier momento. Las primeras conexiones a internet desde dispositivos móviles se realizaron a través de la tecnología WAP (Wireless Application Protocol) hasta la aparición de la tecnología GPRS que permitía la conexión mediante protocolo TCP/IP. A partir de estas conexiones han surgido otras tecnologías, como EDGE, HSDPA, etc., que permitían y permiten la conexión a internet desde dispositivos móviles. Hoy en día la demanda de servicios de red inalámbrica crece de forma rápida y exponencial, todo el mundo quiere servicios de banda ancha en cualquier lugar y en cualquier momento. En este documento se analiza la tecnología WiMAX ( Worldwide Interoperability for Microwave Access) que es una tecnología de banda ancha basada en el estándar IEEE 802.16 creada para brindar servicios a la demanda emergente en la banda ancha desde un punto de vista tecnológico, donde se da una visión de la parte técnica de la tecnología; y desde el punto de vista del mercado, donde se analiza el despliegue y desarrollo de la tecnología desde el punto de vista de negocio. WiMAX es una tecnología que permite la transmisión inalámbrica de datos en áreas de hasta 48Km de radio y que está diseñada como alternativa inalámbrica para ADSL y para conectar nodos de red inalámbrica en áreas metropolitanas. A diferencia de los sistemas inalámbricos existentes que están limitados en su mayoría a unos cientos de metros, WiMAX ofrece una mayor cobertura y un mayor ancho de banda que permita dar soporte a nuevas aplicaciones, además de alcanzar altas tasas de transmisión de datos en grandes áreas con una gran cantidad de usuarios. Se trata de una alternativa a las redes de acceso de banda ancha como DSL o Wi-Fi, que puede dar acceso de banda ancha a lugares tales como zonas rurales o zonas en vías de desarrollo por todo el mundo con rapidez. Existen dos tecnologías de WiMAX, WiMAX fijo (basado en el estándar IEEE 802.16d-2004) y WiMAX móvil (basado en el estándar IEEE 802.16e-2005). La tecnología fija está diseñada para comunicaciones punto a multipunto, mientras que la fija lo está para comunicaciones multipunto a multipunto. WiMAX móvil se basa en la tecnología OFDM que ofrece ventajas en términos de latencia, eficiencia en el uso del espectro y soporte avanzado para antenas. La modulación OFDM es muy robusta frente al multitrayecto, que es muy habitual en los canales de radiodifusión, frente al desvanecimiento debido a las condiciones meteorológicas y frente a las interferencias de RF. Una vez creada la tecnología WiMAX, poseedora de las características idóneas para solventar la demanda del mercado, ha de darse el siguiente paso, hay que convencer a la industria de las telecomunicaciones de que dicha tecnología realmente es la solución para que apoyen su implantación en el mercado de la banda ancha para las redes inalámbricas. Es aquí donde entra en juego el estudio del mercado que se realiza en este documento. WiMAX se enfrenta a un mercado exigente en el que a parte de tener que dar soporte a la demanda técnica, ha de ofrecer una rentabilidad económica a la industria de las comunicaciones móviles y más concretamente a las operadoras móviles que son quienes dentro del sector de las telecomunicaciones finalmente han de confiar en la tecnología para dar soporte a sus usuarios ya que estos al fin y al cabo lo único que quieren es que su dispositivo móvil satisfaga sus necesidades independientemente de la tecnología que utilicen para tener acceso a la red inalámbrica de banda ancha. Quizás el mayor problema al que se ha enfrentado WiMAX haya sido la situación económica en la que se encuentra el mundo. WiMAX a comenzado su andadura en uno de los peores momentos, pero aun así se presenta como una tecnología capaz de ayudar al mundo a salir hacia delante en estos tiempos tan duros. Finalmente se analiza uno de los debates existentes hoy en día en el sector de las comunicaciones móviles, WiMAX vs. LTE. Como se puede observar en el documento realmente una tecnología no saldrá victoriosa frente a la otra, si no que ambas tecnologías podrán coexistir y trabajar de forma conjunta.
