A percepção da inovação em chassis de ônibus rodoviários sob as óticas de clientes e usuários do sistema brasileiro de transporte

Stival, Idam Lauren January 2009 (has links)
Esta pesquisa trata da percepção da inovação por parte dos usuários e clientes no mercado rodoviário brasileiro de transporte de pessoas, mais especificamente das tecnologias e inovações presentes nos chassis de ônibus rodoviário. Recentemente, este setor sofreu forte transformação voltando-se à simplificação de ceículos e componentes e a uma consequentemente redução das inovações e tecnologias utilizadas nos veículos. O objetivo geral desta pesquisa foi identificar os aspectos ligados à percepção da inovação em chassis de ônibus rodoviários sob as óticas de clientes e usuários finais do sistema de transporte. Esta pesquisa tembém identificou quais fatores presentes nos ônibus rodoviários foram apontados como significativos sob a ótica dos usuários e quais inovações e tecnologias são conhecidas da maioria dos passageiros. Este trabalho também identificou quais fatores levam as empresas de transporte rodoviário adquirir determinados modelos de chassis em detrimento a outros mais especificados, com maior número de tecnologias e inovações embarcadas. Para a realização desta pesquisa foi adotado o procedimento de documentação direta de uma situação de mercado, com a coleta de dados realizada junto a 159 usuários - passageiros - de transporte rodoviário de passageiros, mais especificamente aqueles que utilizam a cidade de Curitiba como rota para seus itinerários de viagem. Também foram entrevistados 28 clientes pertencentes a 20 empresas do sistema de transporte, definidos nesta pesquisa como empresas de transporte rodoviário de pessoas e as empresas que fabricam a carroçaria dos ônibus rodoviários. Como resultado, a pesquisa disgnosticou a falta de percepção de inovação e a consequente indiferença por parte dos usuários no momento de escolher uma empresa ou veículo de transporte para viajar. Com relação às empresas de transporte de passageiros foi identificada uma forte tendência à aquisição de veículos que ofereçam tão somente um custo atrativo. Por mais que os clientes de chassis de ônibus identifiquem e reconheçam os benefícios de algumas inovações e tecnologias disponíveis no setor, o fator custo é determinante para a quisição da frota na maioria das empresas. Essa estratégia adotada pode, inclusive, ter sido responsável pelo recente aumento no número de acidentes envolvendo ônibus rodoviários nas estradas brasileiras. / This research becomes to the innovation perception of users - passengers - and clients - people transportation companies and bodybuilder companies - within Brazilian transportation market, specifically technologies an innovations applied in the coaches. Recently this field has suffered a hard change becoming to low end vehicles and components. As consequence this market presents a reduction of innovations and technologies applied in the coaches. The main research achievement was to identify by lens of clients and passengers of Brazilian transportation sytem the aspects relative to innovation perception at coach chassis. This research has identified which faactors or features embodied in the vehicles were appointed as strongly significant according to passenger vision and also which sort of innovations are recognized by them. The research also identified the factors that lead the transport companies to acquire some simplified chassis instead of other ones with technologies and innovations embarked. The research accomplishment required adopts a methodology based ondirect market documentation. Its data acquisition was done with 159 passengers of Brazilian road transporte system; specifically those are using the Curitiba city bus station as part of trip journey. Also were interviewed 28 clients from 20 companies of transportation system, which are defined as companies of passengers transport, as well as, body builder factories. As expected results the research showed the complete lack of awareness and insensibility regarding to users when they are choosing a bus or company to travel. However, result identified by passenger transportation companies shows a strong trend to acquire products based on low end attractiveness or appeal. No matter how much the coach clients have been identified and even recognized some innovations and technologies benefits available in this market, the cost issue is determining factor to fleet acquisition in the majority of the companies. Thiss strategy adopted by passenger transport companies could contribute for the recent raise of accidents involving coaches at Brazilizn roads. / 5000-11-25

ICT and education in a less privileged school of NMBA

Mahleza, Nomfundo January 2013 (has links)
Today’s society requires citizens to have a greater knowledge of information technology (IT) than in previous decades. Strategy programs at a national level define the skill needed in an information society and encourage people to learn these skills (Ministry of Education, 2004). In order for everybody to have the opportunity to learn the basics of the new technology, computer science should be included in general education. The development of technology, like Information and Communication Technology (ICT) has turned the world into a global village (Hashem, 2006). The key instrument in this globalisation is the personal computer. Computer–mediated communication is increasingly becoming the dominant means of communication, particularly in the developed and in some developing countries (Adebisi, 2008). In a developing country, ICT is one of the prime ingredients for development. This generally means improvement of people’s lifestyle through improved education, income, skills development and employment. Development should now also be viewed as a multidimensional process involving major changes in social structures, popular attitudes and a national progression of life from unsatisfactory to satisfactory (Servaes, 1999). Since one of the goals of education is to prepare students for work and citizenship, schools are attempting to change their policies, practices and a curriculum to meet the challenge of making pupils ready for a future quite different than the immediate past (Turker & Codding, 1998). The integration of ICT into the teaching and learning environment in secondary education in Port Elizabeth could change learning and teaching attitudes of learners and teachers and help to prepare them for future challenges. However, the success of this integration will depend on how the learners and teachers adapt to the changes and whether they can make ICT technologies part of their daily life. As it is, there is little or no information available regarding the extent of current ICT usage and access in these secondary schools. The research focuses on the availability, usage and the impact of ICT in education, particularly at a secondary school in the poverty-stricken area of Zwide in Port Elizabeth.

Factors related to technology implementation of K-12 principals and teachers.

Moses, Rhonda René 08 1900 (has links)
The purpose of this study was to determine the relationship between principals' leadership styles and principals'/teachers' implementation of technology. The Leadership Effectiveness and Adaptability Description (LEAD) Self was used to identify the primary and secondary leadership styles of principals. The Level of Technology Implementation (LoTi) Questionnaire was used to identify the level of technology implementation (LoTi), personal computer use (PCU) and current instructional practice (CIP) scores for both teachers and principals. Data collected from 390 K-12 teachers and 22 principals of three large suburban districts in the Dallas-Fort Worth Metroplex was included in data analysis. The findings suggest that differing leadership styles do play a role in the LoTi, PCU, and CIP scores among teachers. Based on descriptive statistics it was determined that teachers with "participating" principals had higher mean LoTi and PCU scores than those with "telling" and "selling" principals. The difference in the mean PCU scores was statistically significant (p<.05) for teachers with "selling" and "participating" principals. Results also showed there was a statistical significance (p<.05) in the mean PCU and CIP scores of teachers working for principals with weak and high adaptability. Due to the low number of principals participating in this study, there is a need to conduct the same research using a larger more diverse sample of principals. The majority of principals in this study had either a primary leadership style of "participating" and a secondary leadership style of "selling" or vice versa. A larger population of principals would hopefully allow for the study of additional leadership styles and their effect on teacher use and implementation of technology.

The Impact of Technological Change on Psychosocial Change and on Modern Man's Ability to Accommodate to These Changes

Cook, Donald Earl 08 1900 (has links)
The problem with which this study is concerned is the investigation of certain selected elements of technological change upon certain selected elements of psychosocial change and the relationship of such changes upon modern man's ability to adjust to these changes. The necessity for psychosocial change and, consequently, adjustment, has risen dramatically in the past few decades as a result of rapid technological and scientific advances for which modern man has been ill-prepared.

The role of information and communication technologies in harnessing information for women in rural development : case studies of South Africa and Kenya

Kituyi-Kwake, Alice Wafula January 2007 (has links)
Thesis submitted in fulfillment of the requirements or the award of the degree of Doctor of Philosophy (Library and Information Science) at the University of Zululand, 2007. / The purpose of this study was to investigate and identify ICTs that provide access to information/ enhance quality of life, and improve the economic standards of rural women by conceptualizing a model for the development, management, exploitation and use of ICTs in an African rural environment. In order to obtain data from the respondents, two research methods were utilized, namely the case study and survey research. In the former, data was collected from key informants in organizations that work with ICTs and rural women. Using frame lists from both South Africa and Kenya, a total of four organizations were purposefully selected, i.e. Womensnet and the National Community Radio Forum (NCRF) in South Africa, and AfriAfya and the Arid Lands Information Network (ALJN-EA) in Kenya. The survey research method was used to interview women aged between 16 and 60 years. 400 respondents formed the sampling size, randomly selected from census household data. Survey data in Kenya was obtained from the sub¬divisions of the Kaplamai Division in Trans-Nzoia district, namely: Kimoson, Sinyerere, Sitatunga and Makutano. The sample frame included: small-scale traders (68; 34%); housewives (29; 14.5%); educators/teachers (27; 13.5); farmers (26; 13.0); students (11; 5.5%); domestic workers (10; 5.0%); preachers (10; 5.0%); farm workers (6; 3.0%); large-scale entrepreneurs (5; 2.5%); nurses (4; 2.0%); clerical workers (2; 1.0%); and community development workers (2; 1.0%). In South Africa, a similar sample frame included: small-scale traders (58; 29.0%); housewives/homemakers (48; 24.0%); farm employees (25; 12.5%); domestic workers (18; 9.0%); educators/teachers (16; 8.0%); students (15; 7.5%); entrepreneurs managing large-scale enterprises (3; 1.5%); clerical workers (9; 4.5%); community development workers (6; 3.0%); and two preachers (2; 1.0%). Sampling data was obtained from census household data belonging to the magisterial districts of Umlalazi, i.e. Eshowe, Amatikulu, Gigindlovu and Mtunzini. By using the snowball sampling technique, female respondents directly and indirectly connected to one another were identified and consequently interviewed. A few major recommendations stemming from the study include the need for: women to be involved in deciding which ICTs would directly and immediately benefit their lives; sensitization and training in the use of ICTS before project implementation; resource centers with skilled human resources and technological capacities to train communities about ICTs; more enhanced collaboration with rural women by being flexible and aware of their needs and requirements; collaborative efforts with other stakeholders at community level; the establishment of intermediary working committees at community level for enhanced communication processes; and a feasibility study that assesses the physical infrastructure and needs assessment survey before project implementation. The study concluded that there is a strong co-relation between the levels of education of a community, types of ICTs used, information seeking behavior, and the socio-economic landscape/environment. It was also established that the enactment of a National Policy on ICT development does not guarantee the efficient and effective use of ICTs, especially by marginalized rural communities. Special efforts must be made to involve rural communities. These efforts would require policies that: encourage competition between various stakeholders in the telecommunications industry, govern the costs of ICTs, and govern connectivity in areas that are not commercially viable. As women form the majority of most rural households, special efforts need to be made in order to involve women in development initiatives such as skills enhancement initiatives, participatory mechanisms and follow-up programs.

Computer Aided Design of Permutation, Linear, and Affine-Linear Reversible Circuits in the General and Linear Nearest-Neighbor Models

Schaeffer, Ben 21 June 2013 (has links)
With the probable end of Moore's Law in the near future, and with advances in nanotechnology, new forms of computing are likely to become available. Reversible computing is one of these possible future technologies, and it employs reversible circuits. Reversible circuits in a classical form have the potential for lower power consumption than existing technology, and in a quantum form permit new types of encryption and computation. One fundamental challenge in synthesizing the most general type of reversible circuit is that the storage space for fully specifying input-output descriptions becomes exponentially large as the number of inputs increases linearly. Certain restricted classes of reversible circuits, namely affine-linear, linear, and permutation circuits, have much more compact representations. The synthesis methods which operate on these restricted classes of reversible circuits are capable of synthesizing circuits with hundreds of inputs. In this thesis new types of synthesis methods are introduced for affine-linear, linear, and permutation circuits, as well as a synthesizable HDL design for a scalable, systolic processor for linear reversible circuit synthesis.

Artificial Intelligence vs. Human Coaches: A Mixed Methods Randomized Controlled Experiment on Client Experiences and Outcomes

Barger, Amber January 2024 (has links)
The rise of artificial intelligence (AI) challenges us to explore whether human-to-human relationships can extend to AI, potentially reshaping the future of coaching. The purpose of this study was to examine client perceptions of being coached by a simulated AI coach, who was embodied as a vocally conversational live-motion avatar, compared to client perceptions of a human coach. It explored if and how client ratings of coaching process measures and outcome measures aligned between the two coach treatments. In this mixed methods randomized controlled trial (RCT), 81 graduate students enrolled in the study and identified a personally relevant goal to pursue. The study deployed an alternative-treatments between-subjects design, with one-third of participants receiving coaching from simulated AI coaches, another third engaging with seasoned human coaches, and the rest forming the control group. Both treatment groups had one 60-minute session guided by the CLEAR (contract, listen, explore, action, review) coaching model to support each person to gain clarity about their goal and identify specific behaviors that could help each make progress towards their goal. Quantitative data were captured through three surveys and qualitative input was captured through open-ended survey questions and 27 debrief interviews. The study utilized a Wizard of Oz technique from human-computer interaction research, ingeniously designed to sidestep the rapid obsolescence of technology by simulating an advanced AI coaching experience where participants unknowingly interacted with professional human coaches, enabling the assessment of responses to AI coaching in the absence of fully developed autonomous AI systems. The aim was to glean insights into client reactions to a future, fully autonomous AI with the expert capabilities of a human coach. Contrary to expectations from previous literature, participants did not rate professional human coaches higher than simulated AI coaches in terms of working alliance, session value, or outcomes, which included self-rated competence and goal achievement. In fact, both coached groups made significant progress compared to the control group, with participants convincingly engaging with their respective coaches, as confirmed by a novel believability index. The findings challenge prevailing assumptions about human uniqueness in relation to technology. The rapid advancement of AI suggests a revolutionary shift in coaching, where AI could take on a central and surprisingly effective role, redefining what we thought only human coaches could do and reshaping their role in the age of AI.

The adoption of innovative wood processing technologies in the building products industry

Cohen, David H. January 1989 (has links)
The strategic importance of the adoption of innovative processing technologies was analyzed for building products businesses. This study examined the two components of wood building products businesses: the structural panel industry and the softwood Iumber industry. To ensure that the relevance of adopting of innovative processing technologies was examined within an accurate contextual environment, additional important strategies and performance were also measured. A mail survey of the seventy-five largest North American producers of these two products provided the primary data necessary to investigate the strategic importance of process technology adoption, forward vertical integration, relative market share, grade sector focus, and investment intensity on firm performance as measured by profitability surrogates and changes in relative market share. This survey collected direct measures of the proportion of 1987 production produced by respondent firms that used controlled distribution channels and each of twentythree processes indicative of innovative technologies in the manufacture of building products. Information concerning the other strategic and performance factors was collected from secondary data sources. Results indicate that the adoption of innovative processing technologies has a positive impact on firm profitability. Investment intensity and grade sector focus also contributed to superior profitability. Forward vertical integration, and relative market share had no impact in differences between performance levels for the firms studied. Technologies were examined for underlying dimensions that group different process technologies together. Firms were clustered according to their level of adoption of innovative processing technologies and these clusters were then described according to a variety of firm-dependent characteristics, strategies, and performance measures. A strategy-performance model was developed for standardized, industrial product-markets and empirically tested using the data collected for the building products industry as an industry representative of this type of competitive environment. / Ph.

Virtual Entrepreneurship: Explicating the Antecedents of Firm Performance

Chandna, Vallari 05 1900 (has links)
Prior research has examined entrepreneurial businesses spatially located in the physical or offline context; however, recent radical information and technological breakthroughs allow entrepreneurs to launch their businesses completely online. The growth of the online business industry has been phenomenal. Predictions for worldwide online sales estimate it to reach $2 trillion in 2016. Virtual entrepreneurship refers to the pursuit and exploitation of opportunities via virtual platforms. Web 2.0 cybermediaries offer web-based platforms that function similarly to traditional intermediaries in a virtual setting and minimize barriers to entry for virtual entrepreneurial firms. The use of such cybermediaries with increasing success suggests an implicit shift in the dominant logic that typically underpins the functioning of entrepreneurial firms operating in the physical world. In this relatively uncharted territory, marked by a focus on profit, cooperation, collaboration and community, three ideal-type institutional logics i.e. Market, Corporation and Community, blend together. It is posited that a Virtual Entrepreneurial Logic guides the norms, behaviors, and practices of entrepreneurial firms operating via these virtual platforms. This raises the question whether the blending of three ideal-type logics leads to the existence of different antecedents of performance. A business model antecedent addressing the economic dimension, a community antecedent addressing the community dimension and a co-creation antecedent addressing the collaborative dimension of the Virtual Entrepreneurial Logic were therefore empirically examined in this study. Thus, three research questions were investigated to explicate the antecedents. Primary data from 1396 virtual entrepreneurial firms was collected (business model antecedent n=366, community antecedent n=732 and co-creation antecedent n= 298) to test the proposed hypotheses. Results provided support for the three antecedents. This study makes important theoretical and practical contributions to understanding the domain of virtual entrepreneurship from a blended logics perspective. Using the theoretical lens provided by institutional logics helps shed light on the pivotal role played by cybermediary platforms in the Web 2.0 context. The primary role of synergistic effects, cooperative behavior, and collaboration have important implications for virtual entrepreneurship. Findings also contribute to other related streams in entrepreneurship such as microenterprises. The study offers theoretical extensions of prior work on co-creation to virtual small entrepreneurial ventures. From a practical standpoint, insights can help entrepreneurs to better understand and leverage performance drivers in virtual contexts in general and on cybermediary platforms in particular.
