Estimation of cost allocation coefficients at the farm level using an entropy approach

This paper aims to estimate the farm cost allocation coefficients from whole-farm input costs. An entropy approach was developed under a Tobit formulation and was applied to a sample of farms from the 2004 Farm Accountancy Data Network data base for Alentejo region, Southern Portugal. A Generalized Maximum Entropy model and Cross Generalized Entropy model were developed to the sample conditions and were tested. Model results were assessed in terms of their precision and estimation power and were compared with the observed data. The entropy approach showed to be a flexible and valid tool to estimate incomplete information, namely regarding farm costs.     

Quantifying the Third Sector in Portugal: An Overview and Evolution from 1997 to 2007

This article presents a global overview of the third sector in Portugal drawing on data from a linked employer–employee database—“Quadros de Pessoal,” which is based on a compulsory annual inquiry to organizations, making it a better source of information than those based on sample surveys and estimates. This study advances on previous overviews by providing more updated numbers for organization size, age, gross revenue and employment levels, as well as their distribution across the ICNPO third sector activity classification. The evolution of these variables from the period 1997 to 2007 is also analyzed. The Portuguese third sector has been fast growing, with revenues amounting to 5.64% of Portugal’s GDP and employment representing 4% of the country’s employment in 2007. It is mainly composed of very small organizations, with diminutive revenues. Perhaps its most striking features are the uneven distribution of employment and revenue and the strong concentration on social services.     

Reference model for implementing ERP systems: an analytical innovation networks perspective

The process for implementing ERP systems is related with the identification of a large range of variables (organisational goals, business rules, business processes, actors, resources and specifics and unique concepts to support these variables). The main agents related to the implementation are the solution supplier, the customer company and the consulting service. If the implementation process is addressed as an organisational innovation, the question is: How to coordinate the ERP implementation resources from an innovation agents network? In order to answer this question, a reference model is proposed for the formation and management of an innovation agent’s network for ERP implementation. The research method is based on a multi-case study for identifying the requirements and to elaborate the reference model applying a modelling method the Enterprise Knowledge Development (EKD). As results, the reference model in an analytical perspective of innovation networks and their drivers, enables to identify, understand and support the process of implementing ERP systems under the EKD models they are: goals; business rules; business processes; actors and resources; concepts; technical components and requirements.     

Precaution and liquidity in the demand for housing

We exploit cross-sectional mortgage data to investigate the importance of liquidity constraints and a precautionary motive in the demand for housing. Households that are not liquidity constrained consume housing services essentially as the life cycle hypothesis suggests but with a significant precautionary component. Households that are liquidity constrained, in terms of not meeting standard loan-to-value or payments-to-income constraints, are similar to unconstrained households in most respects, including the precautionary motive, but they respond somewhat less to fluctuations in their lifetime income - suggesting some influence of bank-induced liquidity constraints. We additionally find, however, that banks enforce liquidity constraints only weakly.     

Ergonomic and usability analysis on a sample of automobile dashboards

This is a research study based on an analysis which sets out to identify and pinpoint ergonomic and usability problems found in a sample of automobile dashboards. The sample consisted of three dashboards, of three different makes and characterized as being a popular model, an average model and a luxury model. The examination was conducted by observation, with the aid of photography, notes and open interview, questionnaires and performing tasks with users, the bases of which are on the principles laid down by methodologies. From this it was possible to point to the existence of problems such as: complaints about the layout, lighting, colors, available area, difficult access to points of interaction, such as buttons, and the difficult nomenclature of dials. Later, the findings and recommendations presented show the need for a further, deeper study, using more accurate tools, a larger sample of users, and an anthropometric study focused on the dashboard, since reading and understanding it have to be done quickly and accurately, and that more attention be given to the study of automobile dashboards, particularly in the most popular vehicles in order to maintain the standards of usability, and drivers' comfort and safety.     

A method to assess safety and resilience in radiopharmaceuticals production process

Radiopharmaceuticals are radiation-emitting substances used in medicine for radiotherapy and imaging diagnosis. A Research Institute, located in Rio de Janeiro, produces three radiopharmaceuticals: the sodium iodate is used in the diagnosis of thyroid dysfunctions, the meta-iodo-benzylguanidine is used in the diagnosis of cardiac diseases, and the fluordesoxyglucose is used in diagnosis in cardiology, oncology, neurology and neuropsychiatry. This paper presents a method to access safety and resilience in radiopharmaceuticals production processes. The method uses resilience indicators in order to proactively evaluate and manage the safety.     

The ambivalence of the work of the hotel managers: an approach to ergonomics

This article uses the contributions of ergonomics to understand the work performed by hotel managers. The concern to understand the job of managers is something new in the ergonomics and few studies address this issue, especially in what concerns the work of hotel managers and its aspects of performance and health, which is the focus of this article. Through a literature review on the subject, it is sought to understand the managers' work activity, the impacts on their health and their organizational performance, as managers take an ambivalent position in organizations, since they have to deal directly with the demands of upper and lower hierarchies in a context of high competition, organizational changes and user requirements. It is then inferred there is a risk of increased work density for managers, bringing negative consequences to their health and organizational performance. This phenomenon, still poorly covered by ergonomics, contributes to a certain invisibility of the manager's work in society as a whole, when the manager may suffer from health problems, which are also common in certain populations of workers who do not take the managerial function.     

The construction of ergonomic demands: application on artisan fishing using jangada fishing rafts in the beach of Ponta Negra

The present article seeks the process of construction of ergonomics demand referring to the artisan fishing activityfound in Ponta Negra beach located in the city of Natal, Brazil. The instruction/construction of demands correspond to the first stage of Work Ergonomic Analysis and allows the understanding of real issues existent in a work situation, rank them and route the providences. The demand presented on this study, features itself as a induced demand, process which some potential demands or hypothetical demands are taken to an organization, after a preview analysis of the work aimed by the study, resulting from a theoretical research (state of the art) and/or from analysis of a reference situation (state of practice), where demands hypothesis are taken in consideration about the pretended work. The demands construction process using interactional methods and techniques, observation methods and techniques and bibliographic research, researches in state of reference or document. This article demonstrates the efficiency of the methodological choice to construct real ergonomic demands and highlights the importance of social construction on that process, which main goal is to refer the ergonomic actions that allow the improvement of work and life conditions for the fishers and sustainability to Jangadeira activity.     

Smoking Risks in Spain: Part II—Perceptions of Environmental Tobacco Smoke Externalities

Previous studies of smoking risk beliefs have focused almost exclusively on risks to the smoker. Using an original set of survey data from Spain, we examine the public's perceived risks from exposures to environmental tobacco smoke. The risk categories considered included lung cancer, heart disease, life expectancy loss, and low birth weight for children of smoking mothers. Risk beliefs were quite high, often dwarfing scientific estimates of the risk. The results are consistent with overestimation of risks from highly publicized, low probability events.     

Decision-Making processes in the child protection system: A comparative study between students and professionals in Portugal

Abstract

This research aims to achieve a better understanding of factors that influence the assessments and decisions of professionals and students about the possibility to remove a child at risk from her birth family. The study also analyzes the influence of the attitudes of the child’s mother on that decision. It was used a questionnaire based on a case vignette of alleged child maltreatment. Compared with students, professionals were more pro-removal, more in favor of reunification and parents’ participation in the decisions, and had a higher assessment of emotional abuse, and emotional and physical neglect. Mother’s wish did not show to have any impact in the two samples regarding maltreatment, risk assessments, and intervention recommendations.
