This study deals with using digital photogrammetry to make an anthropometric analysis of wheelchair users. To analyse the data, Digita software was used, which was made available by means of the agreement of the Design Department of the Federal University of Pernambuco--Brazil--with the Department of Ergonomics of the Technical University of Lisbon--Portugal. Data collection involved a random sample of 18 subjects and occurred in the Biomechanics Laboratory of the Maurice of Nassau Faculty, located in Recife, Pernambuco. The methodology applied comprises the steps of Ergonomic Assessment, Configuration of the Data Base, Taking Digital Photographs, Digitalising the Coordinates and Presentation of Results. 15 structural variables related to static anthropometry were analysed, and 4 functional range variables relating to dynamic anthropometry. The results were presented by analysing personal data, classified by gender, ethnicity and age; by functional analysis of the sample, classified by clinical diagnosis, results of assessing the joints, results of the evaluation through motion and postural evaluation; and of the analysis of the anthropometric sample, which indicated for each variable the number of people, the mean, the standard deviation, and the minimum, median and maximum values. 相似文献

Work in organizations requires a minimum level of consensus on the understanding of the practices performed. To adopt technological devices to support the activities in environments where work is complex, characterized by the interdependence among a large number of variables, understanding about how work is done not only takes an even greater importance, but also becomes a more difficult task. Therefore, this study aims to present a method for modeling of work in complex systems, which allows improving the knowledge about the way activities are performed where these activities do not simply happen by performing procedures. Uniting techniques of Cognitive Task Analysis with the concept of Work Process, this work seeks to provide a method capable of providing a detailed and accurate vision of how people perform their tasks, in order to apply information systems for supporting work in organizations. 相似文献

This article aims to highlight the role of consumer products companies in the heart and the extent of accidents involving these types of products, and as such undesired events take part as an agent in influencing decision making for the purchase of a product that nature on the part of consumers and users. The article demonstrates, by reference, interviews and case studies such as the development of poorly designed products and design errors of design can influence the usage behavior of users, thus leading to accidents, and also negatively affect the next image of a company. The full explanation of these types of questions aims to raise awareness, plan on a reliable usability, users and consumers in general about the safe use of consumer products, and also safeguard their rights before a legal system of consumer protection, even far away by the CDC--Code of Consumer Protection. 相似文献

Understanding and predicting people's displacement movement is particularly important for professionals involved in planning complex buildings (e.g., hospitals, convention centers, subway stations and university campus). Some decisions taken by the visitors while choosing what route to follow can be influenced by some environmental cues which can act as a factor of attraction, influencing the wayfinding process. Therefore, the main objective of this study was to evaluate the hypotheses that, in the context of a simulated emergency egress, people prefer to move along either a wider and with more lighting corridor or to bear right. To collect the users' responses, a constant stimulus method was used, combined with a two forced choices method, involving the projection of stereoscopic images in a wall-screen. Results suggest that, in a "T-type" intersection, users randomly chose which direction to follow. However, if there is an increment in the width of the side corridor, users tend to follow the wider corridor. When light is inserted, users also prefer to choose the corridors with more lighting. In situations where the variables corridor width and existence of lighting are concurrent, the corridors with light are the most chosen by the users. 相似文献

Crude oil and natural gas depletion may be modelled by a diffusion process based upon a constrained life-cycle. Here we consider
the Generalized Bass Model. The choice is motivated by the realistic assumption that there is a self-evident link between
oil and gas extraction and the spreading of the modern technologies in wide areas such as transport, heating, cooling, chemistry
and hydrocarbon fuels consumption. Such a model may include deterministic or semi-deterministic regulatory interventions.
Statistical analysis is based upon nonlinear methodologies and more flexible autoregressive structure of residuals. The technical
aim of this paper is to outline the meaningful hierarchy existing among the components of such diffusion models. Statistical
effort in residual component analysis may be read as a significant confirmation of a well-founded diffusion process under
rare but strong deterministic shocks. Applications of such ideas are proposed with reference to world oil and gas production
data and to particular regions such as mainland U.S.A., U.K., Norway and Alaska. The main results give new evidence in time-peaks
location and in residual
times to depletion. 相似文献

A radiological dispersal device (RDD) is a simple weapon capable of causing human harm, environmental contamination, disruption, area denial, and economic cost. It can affect small, large, or long areas depending on atmospheric stability. The risk of developing a radio‐induced cancer depends on exposure, and an effective response depends upon available timely guidance. This article proposes and demonstrates a convergence of three different capabilities to assess risk and support rapid safe resource efficient response. The three capabilities that are integrated are Hotspot for dispersion, RERF for epidemiological risk, and RESRAD‐RDD for response guidance. The combined methodology supports decisions on risk reduction and resource allocation through work schedules, the designation and composition of response teams, and siting for operations. In the illustrative RDD scenario, the contamination area for sheltering, evacuation, and long‐term public concern was greatest for calm atmospheric conditions, whilst close‐quarter responders faced highest dose rates for neutral atmospheric conditions. Generally, the risks to women responders were found to be significantly greater than for men, and the risks to 20‐year‐old responders were three times that of their 60‐year‐old counterparts for similar exposure. 相似文献

The authors present a qualitative study of voluntary career change, which highlighted the importance of positive emotions, unplanned action, and building certainty and perceiving continuity in the realization of change. Interpretative phenomenological analysis was used to broaden theoretical understanding of real‐life career decision making. The accounts of 8 women who had changed careers were explored, and the analysis supported other‐than‐rational perspectives of career decision making. An action‐affect‐cognition framework of decision making is proposed. The framework adds the role of emotion and the importance of self‐regulation to existing theory of career decision making. Implications for career counseling are discussed. 相似文献

This article examines how a least developed country-based social business first creates operational capabilities (OCs) and then, over time, builds innovative capabilities (ICs) to fulfil a social need, be self-sustainable and achieve inclusive innovation. This relationship is examined in Bangladesh's Grameen Danone Foods Limited (GDFL) by integrating the technological capability and inclusive innovation theoretical frameworks and by using data gathered through extensive fieldwork. Broadly, our findings show how GDFL built and accumulated basic and intermediate ICs to undertake innovative activities in all areas of operation. Specifically, our findings scrutinize the process in which a social business develops and organizes its resources to initially build OCs and engage in the creation of ICs through various learning mechanisms to deliver inclusive innovation. From this process, we also observe a set of unpredicted positive spillovers to the community, which expands the inclusiveness effect. The findings also suggest that having a social orientation, triggers the use of different resources from within and outside the firm to achieve inclusive innovation. We conclude by discussing the study's implications for scholars, policy-makers and managers of multinational's social businesses. We also highlight future research areas, and crucially those related to key emerging conceptual limitations of inclusive innovation and development. 相似文献

The international system is still governed by a normative framework designed mainly by OECD countries, especially with regard to soft‐law standards in the field of development co‐operation. However, the growing relevance of ‘Eastern donors’ is weakening its efficiency and raises the question of how compliance with these standards can be assured in a changing donor landscape. Despite efforts to integrate emerging countries into the traditional approach of the OECD Development Assistance Committee (DAC) to monitoring compliance through peer reviews, the aid architecture of the future might turn out to be a synthesis of established and new approaches. 相似文献
