A Virtual Joystick as a Novel Interaction Modality for Surgeon-Computer Interaction During Computer-Assisted Surgical Procedures

Interacting with a computer system in the operating room (OR) can be a frustrating experience for a surgeon, who currently has to verbally delegate to an assistant every computer interaction task. This indirect mode of interaction is time consuming, error prone and can lead to poor usability of OR computer systems. This thesis describes the design and evaluation of a joystick-like device that allows direct surgeon control of the computer in the OR. The device was tested extensively in comparison to a mouse and delegated dictation with seven surgeons, eleven residents, and five graduate students. The device contains no electronic parts, is easy to use, is unobtrusive, has no physical connection to the computer and makes use of an existing tool in the OR. We performed a user study to determine its effectiveness in allowing a user to perform all the tasks they would be expected to perform on an OR computer system during a computer-assisted surgery. Dictation was found to be superior to the joystick in qualitative measures, but the joystick was preferred over dictation in user satisfaction responses. The mouse outperformed both joystick and dictation, but it is not a readily accepted modality in the OR.

Fatores que influenciam a intenção de compra online: aplicação de um modelo adaptado de aceitação da tecnologia para o comércio eletrônico

This research aims to understand the factors that influence intention to online purchase of consumers, and to identify between these factors those that influence the users and the nonusers of electronic commerce. Thus, it is an applied, exploratory and descriptive research, developed in a quantitative model. Data collection was done through a questionnaire administered to a sample of 194 graduate students from the Centre for Applied Social Sciences of UFRN and data analysis was performed using descriptive statistics, confirmatory factorial analysis and simple and multiple linear regression analysis. The results of descriptive statistics revealed that respondents in general and users of electronic commerce have positive perceptions of ease of use, usefulness and social influence about buying online, and intend to make purchases on Internet over the next six months. As for the non-users of electronic commerce, they do not trust the Internet to transact business, have negative perceptions of risk and social influence over purchasing online, and does not intend to make purchases on Internet over the next six months. Through confirmatory factorial analysis six factors were set up: behavioral intention, perceived ease of use, perceived usefulness, perceived risk, trust and social influence. Through multiple regression analysis, was observed that all these factors influence online purchase intentions of respondents in general, that only the social influence does not influence the intention to continue buying on the Internet from users of electronic commerce, and that only trust and social influence affect the intention to purchase online from non-users of electronic commerce. Through simple regression analysis, was found that trust influences perceptions of ease of use, usefulness and risk of respondents in general and users of electronic commerce, and that trust does not influence the perceptions of risk of non-users of electronic commerce. Finally, it was also found that the perceived ease of use influences perceived usefulness of the three groups. Given this scenario, it was concluded that it is extremely important that organizations that work with online sales know the factors that influence consumers purchasing intentions in order to gain space in their market

Integrated science and art education for creative climate change communication

An interdisciplinary field trip to a remote marine lab joined graduate students from fine arts and natural resource science departments to think creatively about the topic of climate change and science communication. We followed a learning cycle framework to allow the students to explore marine ecosystems and participate in scientific lectures, group discussions, and an artist-led project making abstract collages representing climate change processes. Students subsequently worked in small groups to develop environmental communication material for public visitors. We assessed the learning activity and the communication product using pre- and post-field trip participant surveys, focus group discussions, and critiques by art and communication experts of the products. Significant changes in knowledge about climate change occurred in program participants. Incorporating artists and the arts into this activity helped engage multiple senses and emphasized social interaction, as well as providing support to participants to think creatively. The production of art helped to encourage peer learning and normalize the different views among participants in communicating about climate change impacts. Students created effective communication products based on external reviews. Disciplinary differences in cultures, language, and standards challenged participating faculty, yet unanticipated outcomes such as potentially transformative learning and improved teacher evaluations resulted.

Avaliação da eficiência dos programas de pós-graduação acadêmicos em Administração, Contabilidade e Turismo

The Triennial Evaluation of Coordination for the Improvement of Higher Education Personnel (CAPES) is made according to several indicators, divided into several issues and items, and their weights. In these it is evident the importance of scientific periodicals. This study aims to evaluate the relative efficiency of post-graduate students in Business Administration, Accounting and tourism evaluated by CAPES in Brazil. The methodology used the data envelopment analysis - DEA (Data Envelopment Analysis). The data were obtained from the site and organized by the CAPES Qualis score. The analysis was performed by the DEA variable returns to scale, product-oriented (BCC-O), with data from the three-year periods 2004-2006 and 2007-2009. Among the main results are the average increase significantly the relative efficiency of the programs in the period 2007-2009 compared to 2004-2006 period, the highest average efficiency of programs linked to public institutions in relation to private, doctoral programs with the present average efficiency sharply higher than those only with masters, and senior programs in general were more efficient. There is also moderate and significant correlation between the efficiency scores and concepts CAPES. The Malmquist index analysis showed that more than 85% of programs had increased productivity. It is noteworthy that the main effect that influences the increase of the Malmquist index is the displacement of the border (Frontier-shift)

Utilização de um ambiente virtual de aprendizagem: um estudo na perspectiva da prática docente

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers

Construção moral dos estudantes de graduação em enfermagem como instrumento para a humanização do cuidado

O cuidado de enfermagem faz parte do mundo científico exigindo não apenas o desenvolvimento de habilidades para a realização de procedimentos técnicos, mas a possibilidade de resgatar a sensibilidade para cuidar de modo humanizado. Pressupõe-se que a construção moral durante o processo de formação dos estudantes de graduação em Enfermagem possibilita o exercício de um cuidado humanizado. Assim, tem-se como objetivo geral: Compreender como ocorre o processo de construção moral dos estudantes de graduação em Enfermagem para o exercício de um cuidado humanizado; e como objetivos específicos: Conhecer quais os valores morais que estão presentes nas ações dos estudantes de enfermagem para a promoção do cuidado humanizado; Refletir acerca de como a construção moral do estudante de graduação em enfermagem pode fomentar a humanização do cuidado; Conhecer barreiras vivenciadas no processo de construção moral dos estudantes de graduação em enfermagem para a realização do cuidado humanizado. Mediante uma abordagem qualitativa e utilizando, como referencial teórico-metodológico, a Etnoenfermagem de Leininger, o estudo foi desenvolvido com 28 estudantes regularmente matriculados na quinta e na sétima séries do Curso de Graduação em Enfermagem. A coleta dos dados ocorreu através de quatro fases de observação, uma fase de entrevista semi-estruturada e quatro fases de análise, identificando-se as categorias:- Processo de construção moral dos estudantes de enfermagem e o cuidado humanizado;- Valores morais nas ações dos estudantes de enfermagem para a promoção do cuidado humanizado;- Construção moral do estudantes de graduação em enfermagem como fomento da humanização do cuidado; - Humanização: barreiras vivenciadas no processo de construção moral dos estudantes de enfermagem. A partir da análise, afirma-se que a construção moral dos estudantes de graduação em Enfermagem, durante o processo de formação, possibilita o exercício de um cuidado humanizado. Destaca-se que o ambiente de formação deve ser um local em que o estudante seja respeitado e considerado como cidadão; estes aspectos culminarão com a possibilidade desse estudante desenvolver competências morais necessárias ao cuidado humanizado. Por outro lado, em um ambiente onde ocorra abuso ou desrespeito ao estudante, existe a tendência de ocorrer o fenômeno inverso, causando uma regressão da competência moral e possíveis repercussões negativas para o cuidado humanizado. Assim, pensar a construção moral dos estudantes de graduação em enfermagem exige das instituições de ensino um compromisso social e político, pois essa reflexão convida a avaliar e revisar suas práticas pedagógicas e condutas adotadas diante dos estudantes. Cabe, às escolas de enfermagem, oportunizar ao graduando, espaços que favoreçam sua construção moral. Na formação em enfermagem, é necessária a priorização das relações humanas e não somente do ensino de teorias e técnicas de cuidado, concluindo-se que o desenvolvimento moral é um dos eixos da humanização do cuidado.

Constructing and (re) constructing professional identities: an analysis on portuguese social educators

Institutions need to be aware of the complex way in which professional trajectories are built upon in order to offer under graduate and graduate students’ different possibilities for developing needed competences to display in practice. This paper focuses on the study2 conducted by ESEPF on its former students of Social Education, through a written questionnaire analysing different parameters of their professional transitions, from entrance at training, first job and entrance on the labour market, present work situations, developed competences and perceptions of the Social Educator role on Portuguese Society, among others. Results will be presented and discussed. Particular focus will be given on the specific role of Social Education and its distinctive features towards other “social work” professions.

Use of Products and Systems for Scientific and Technical College Education and Development for Industrial

Have been less than thirty years since a group of graduate students and computer scientists working on a federal contract performed the first successful connection between two computers located at remote sites. This group known as the NWG Network Working Group, comprised of highly creative geniuses who as soon as they began meeting started talking about things like intellectual graphics, cooperating processes, automation questions, email, and many other interesting possibilities 1 . In 1968, the group's task was to design NWG's first computer network, in October 1969, the first data exchange occurred and by the end of that year a network of four computers was in operation. Since the invention of the telephone in 1876 no other technology has revolutionized the field of communications over the computer network. The number of people who have made great contributions to the creation and development of the Internet are many, the computer network a much more complex than the phone is the result of people of many nationalities and cultures. However, remember that some years later in 19732 two computer scientists Robert Kahn and Vinton Cerft created a more sophisticated communication program called Transmission Control Protocol - Internet Protocol TCP / IP which is still in force in the Internet today.

Through simple regression analysis, was found that trust influences perceptions of ease of use, usefulness and risk of respondents in general and users of electronic commerce, and that trust does not influence the perceptions of risk of non-users of electronic commerce. Finally, it was also found that the perceived ease of use influences perceived usefulness of the three groups. Given this scenario, it was concluded that it is extremely important that organizations that work with online sales know the factors that influence consumers purchasing intentions in order to gain space in their market

Necessidade de cognição, memória de trabalho e recuperação de contra-exemplos para condicionais causais

A procura de contra-exemplos é provavelmente a fase mais importante do raciocí - nio dedutivo, uma vez que visa garantir a validade da conclusão. A explicação mais difundida para a diminuta procura de contra-exemplos é a capacidade limitada da memória de trabalho (Markovits & Barrouillet 2002; De Neys, Schaeken & d’Ydewalle, 2002; 2003; 2005a; 2005b) o que não parece ser suficiente para explicar a pouca iniciativa dos sujeitos em utilizarem a procura de contra-exemplos como estratégia de verificação (Oakhill, & Johnson-Laird, 1985). No presente trabalho testou-se a hipótese de que a necessidade de cognição dos sujeitos (Cacioppo & Petty, 1982) tem influência no processo de recuperação de contra-exemplos, para condicionais causais, de modo aprofundar o conhecimento das razões que levam a que os sujeitos procurem tão poucos contra-exemplos durante o raciocínio dedutivo (Oakhill, & Johnson-Laird, 1985; Johnson-laird, 2006). Para o efeito, um total de 60 participantes (15 alunos do mestrado integrado em psicologia, 15 alunos de doutoramento, 15 operários fabris e 15 empregados de mesa) realizou 3 tarefas: escala Necessidade de Cognição (Silva & Garcia-Marques, 2006), uma tarefa de raciocínio e uma tarefa para avaliar a capacidade da memória de trabalho (Guerreiro, Quelhas & Garcia-Madruga, 2006). Os resultados indicam que o processo de recuperação de contra-exemplos é influenciado pela necessidade de cognição e que esta influência além de significativa é superior à influência da capacidade da memória de trabalho.
