Para tanto, foi realizada uma pesquisa usando o método Delphi, que consiste em regular, sistematicamente, a apresentação de perguntas acerca de um determinado problema a um grupo de especialistas. Para um levantamento mais abrangente optou-se por aplicar os questionários a três grupos distintos: Acadêmicos, Executivos das montadoras de veículos comerciais e Executivos das indústrias de autopeças. É possível concluir, após a análise dos resultados, que o Brasil possui atualmente uma posição confortável na comercialização de caminhões e ônibus, além de certa autonomia no desenvolvimento desses veículos em relação às empresas matrizes. Adicionalmente destaca-se que poucos foram os argumentos que justificariam mudanças desse cenário até o ano de 2018, porém há claras deficiências – como ausência de profissionais (engenheiros) qualificados no mercado e necessidade de maior intercâmbio entre empresas e Universidades - que devem ser analisadas e superadas de modo a garantir ao Brasil a sustentabilidade no desenvolvimento deste tipo de produto. / The main objective of this Thesis is to present a prospective analysis about the tendencies of the world wide strategies of commercial vehicles’ development, in relation to the current local and international scenery. It has been done a research by using the Delphi method, which consists to regulate, systematically, the presentation of questions about a specific problem to a group of specialists. In order to guarantee more representative data, it has been adopted three distinct groups: Academics, OEMs Managers and OEM´s suppliers Managers. It is noticeable, after the data’s analysis, that Brazil has nowadays a comfortable status on the commercial vehicles’ market and also a good autonomy on product development. The specialists presented few arguments that could justify the modification of this scenery up to 2018, although there are clear evidences – like lack of qualified engineers on Brazilian market and the necessity of a better exchange of knowledge between the OEMs and Universities – that must be analyzed and suppressed, in order to guarantee the Brazilian product development sustainability in this segment.

The use of Standards to reduce the complexity of Health Facilities Design has become an indispensable and integral part of the planning process. Unfortunately the structure of present Standards is inflexible, and while this structure may have been acceptable in the past, the standards it produces have become ineffective. Such Standards have been unable to adapt to the changing attitudes and needs of the planning participants who respond to the societal changes around them. It is our objective to develop a method which can build better Standards. In the first chapter we examine the structural problems of Standards and find that there is a fundamental difference between the positive purpose of Standards as used by hospitals and planners and the restrictive purposes of Standards used by government. We have used the terms Guidelines and Standards to denote these different contexts. Having established that a good Standard is one which is similar to a Guideline, we then explore an alternative structure developed at Berkeley, California, called a "Pattern" which we observe will satisfy the requirements for "good" Standards. Since Pattern formats are admirably suited to developing societally-responsive Guidelines and Standards we evolve a method to assemble these new Standards. This method is based upon the Delphi Technique. It uses the technique's inherent advantages to establish communication between two groups of experts (Planners and Medical) who then interact to explore problems and solutions in planning Newborn Nurseries and Neonatal Intensive Care Units. The methodology which is described in Chapter 2 uses the classical components of a Policy Delphi with three rounds of questionnaires sent to Medical Experts (Physicians and Nurses) in various parts of British Columbia and Alberta. It adds such variations as the including of input from the Planner Experts as one method for the feed back of information. This special Delphi design anticipates effects from independent variables and builds in compensatory steps. One of the steps included is a Mini-Survey of a larger group of potential participants, to evaluate the Patterns resulting from the Delphi Study. This larger group was sixteen hospitals in British Columbia and ten hospitals in Alberta. Chapter 3 describes the details in carrying out the three questioning rounds of this modified Delphi method, and its success in assisting the production of a series of Nursery Patterns which are usable as Guidelines. In the methodology is the inherent capability for retaining flexibility, and there are a series of process adjustments that occur. Evaluation of the method in Chapter 4 shows that despite weaknesses, both anticipated and unanticipated, the results provide an important starting point that helps create better, more usable Standards. Possible future developments are briefly mentioned in the hope that evaluation and change will occur as the planning environment changes about us. / Medicine, Faculty of / Population and Public Health (SPPH), School of / Graduate

O polipropileno também foi selecionado devido à sua grande versatilidade e possibilidade de utilização em aplicações de engenharia, especialmente na forma de compostos. A técnica de prospecção tecnológica utilizada foi o método Delphi que se baseia em um questionário enviado a especialistas da área em rodadas consecutivas para a obtenção de um consenso. O anonimato dos participantes, análise estatística dos resultados e feedback aos respondentes são as principais características deste método. Um questionário envolvendo os aspectos tecnológicos e mercadológicos foi elaborado e enviado aos respondentes em duas rodadas. São observadas nos resultados obtidos tendências de crescimento no mercado de polímeros de engenharia em aplicações de alta temperatura e em substituição aos materiais convencionais como os metais e cerâmicas, principalmente no mercado automotivo, industrial e eletroeletrônico. Avanços em propriedades como performance termo-mecânica e balanço entre rigidez e tenacidade além de inovações nas tecnologias de manufatura e moldagem dos polímeros de engenharia foram indicados como tendências futuras. Medidas para superar obstáculos em custos , definição de políticas públicas e privadas que viabilizem atividades de reciclagem, capacitação e mão de obra e o alinhamento entre indústria, academia e governo serão fundamentais para o sucesso dos polímeros de engenharia nas suas mais diversas aplicações / Abstract: Industry in general and the plastics segment in particular are facing a time of global and strong competition. Also, social claims like environmental care, energy efficient technologies and the need for high quality products are boosting innovations and improvements. On the plastics market, engineering polymers are the best suited materials for these improvements. It is the objective of this work to evaluate the tendencies for improved properties, new modification and reinforcement technologies, new potential applications and volumes of commercialization for this class of materials over the next 20 to 30 years. The first material selected for the research was Nylon 66 due to its huge ease of modification and versatility for application, in addition it is one of the most important engineering polymers. Polypropilene was also selected due to its versatility and possibility of utilization in engineering applications, specially in compounds. Delphi method was used as the research technique, it is based on a questionnaire sent to experts in polymers in successive rounds as a means of achieving consensus. Anonymity of participants, statistical evaluation of results and feedback to the experts are the main characteristics of this method. A questionnaire covering technological and market aspects was developed and sent to the participants in two rounds. It is seen in the results a tendency of growth in the market of engineering polymers for high temperature applications and in traditional materials replacement, like metals and ceramics, specially in the automotive, industrial and electro-electronic markets. Improvements in properties like thermomechanical performance and balance between stiffness and toughness in addition to technology innovations in manufacturing and molding of engineering polymers were pointed as future tendencies. Measures to overcome cost issues, public and private policy implementation to facilitate recicling, work force qualification and alignment between industry, academy and government will be vital for the success of enginering polymers in their various applications / Mestrado / Ciencia e Tecnologia de Materiais / Mestre em Engenharia Química

Introduction: Compassion fatigue is an extreme state of tension and preoccupation with the suffering of those being helped and affects those who work in caring professions. Helping people in distress can traumatise the helper because of their empathetic ability. Nurses who work in ARV clinics witness the suffering of their patients when they listen to their patients' descriptions of the trauma that they have to cope with. The patients get the chance to let go of the trauma and to share their concerns. Unfortunately the nurses often absorb some of the emotional pain of their patients and not all nurses are equipped to handle the situations in such a way that they do not become secondarily affected by the trauma of their patients and therefore, become vulnerable to develop compassion fatigue. If compassion fatigue is not identified in time and addressed adequately, the affected nurses may develop feelings of hopelessness in their ability to take care of their patients with detrimental effect on the quality of nursing care to these patients. Aims: Firstly, to explore and describe the extent of the manifestation of compassion fatigue amongst nurses working in antiretroviral clinics; and secondly, to develop a wellness programme to aid in the identification and management of episodes of compassion fatigue as well as the prevention of future occurrences of such episodes of compassion fatigue amongst nurses working in antiretroviral clinics. Methodology: The researcher conducted the study in two phases. In Phase one, a single embedded case study design, with three sub-units situated within the case, namely nurses who work in the adult, ante-natal and paediatric ARV clinics in a tertiary public hospital, was used. Purposive sampling was used to select seven nurses. Data was collected using semi-structured interviews. The researcher used content analysis as described by Elo and Kyngäs (2008) to analyse the transcribed interviews. The themes identified include the risk to develop compassion fatigue, manifestation of compassion fatigue and strategies to prevent and manage compassion fatigue. For document analysis the researcher used professional and enrolled nurses' job description and the employee health and wellness programme for public service. In Phase two, the researcher developed the wellness programme to aid in the identification, prevention and management of compassion fatigue amongst nurses who work in antiretroviral clinics and the Delphi Method was used to refine the wellness programme. Findings: Nurses working in the ARV clinics are at risk of developing compassion fatigue due to work environment issues such as challenges created by the health care system, lack of support from management, and their overwhelming work load. The cost of the nurse-patient relationship also contributed to nurses being at risk of compassion fatigue. Aspects that were identified that relate to the cost of a relationship with patients who are HIV positive include caring for traumatised patients, vicarious exposure to traumatic experiences of patients, and the influence caring for patients who are HIV positive has had on nurses' personal lives and their families. Nurses can traumatise their family members by continually not being available for them through emotional withdrawal. Nurses presented with physical, psychological, spiritual symptoms and changes in their behaviour that are indicative of compassion fatigue. Various strategies to prevent and manage compassion fatigue were identified: both what nurses can do, and what they expected from management. Nurses' job description is generic and does not spell out their role and function within antiretroviral clinics. The implementation of the health and wellness programme is lacking. The findings of Phase one and related literatures formed the bases from which the researcher developed the wellness programme to aid with the identification, prevention and management of compassion fatigue. Conclusion: Nurses are at risk of developing compassion fatigue due to the cost of the nurse-patient relationship with patients who are HIV positive. The key to prevention of compassion fatigue is awareness and a number of strategies that can aid in the identification, prevention and management of compassion fatigue have been identified and included in the wellness programme. Managerial support and practicing of self-care is important to maintain the health and well-being of nurses who work in antiretroviral clinic. / Thesis (PhD)--University of Pretoria, 2016. / Nursing Science / PhD / Unrestricted

Researchers use the policy Delphi method to explore a complex topic with little historical context that requires expert opinion to fully understand underlying issues. The benefit of this research technique is the use of experts who have more timely information than can be gleamed from extant literature. Additionally, those experts place researchers in a specific moment, thus increasing the possibility of capturing change over time. One limitation of the policy Delphi is the difficulty in developing an accurate initial questionnaire to start the process. The purpose of this article is to identify benefits and limitations of this research method.

The problem for this study was to identify standards desirable for faculty when four-year hospitality management education programs are accredited. A modified Delphi technique was used to determine standards and reach agreement among a panel of hospitality professionals concerning desirable standards to be used to evaluate faculty during the self-study section of the specialized accreditation process. Nine faculty qualifications identified in the literature as being common to the self-study section of specialized accreditation constituted the framework of the study. These qualifications included academic preparation, scholarly productivity, applied professional experience, involvement in professional associations, competency in area of specialization, teaching effectiveness, interest in curricular experimentation, ability to work with students, and public service. A professional panel consisting of 15 hospitality management education administrators/faculty and 12 hospitality management industry representatives developed standards for each of the above qualifications. The panel rated the desirability of the standards using a Likert-type scale (4=very desirable, 3=desirable, 2=undesirable, l=very undesirable). All standards receiving a total of two-thirds of the responding panel members' votes in the very desirable and desirable categories were included in a proposed accreditation model of faculty standards. Unexpectedly, the panel questioned the inclusion of the qualification of public service and agreed to omit the evaluation of faculty on this qualification during specialized accreditation. It was recommended that eight of the qualifications and their corresponding standards be used by The Council on Hotel Restaurant and Institutional Education (CHRIE) to form criteria necessary for the self-study section of specialized accreditation. It was also recommended that the developed standards be used by hospitality management faculty as a means of self-evaluation. Finally, it was recommended that hospitality management education administrators use the standards as (a) guidelines when hiring and evaluating faculty and (b) a means for assessing faculty needs prior to faculty development programs. / Ed.
