Ergonomics and design for all

The paper deals with research areas and actions thanks to which the theoretical and methodological content of the "Ergonomics in Design" project can give a concrete contribution to the "Design for All" project, in particular with regards to the assessment and design of environments, the design of everyday products.     

The Intermodal Bike: multi-modal integration of cycling mobility through product and process innovations in bicycle design

The paper presents the early results of the UE-FP7 project "The Intermodal Bike". The research aim is to provide a super-compactable, super-lightweight folding bicycle as a realistic solution to graft the cycling mode onto the root of the public or private transportation systems. The folding bikes now on the international market reach weighs between 12-15 kg, with a variable footprint but occupying -when compacted- an average volume of about 100 liters. To encourage the use of this vehicle and to extend it to a larger number of users with different characteristics, the research project has set its goal in increasing as possible compactness and light weight, creating a bicycle with a volume when compacted of 20 liters (reduction factor =5), with a shape of 48 × 36 × 12 cm and a weight of 5 kg. max., ensuring stability and improving vehicle usability and efficiency, during the ride and in the phase of bike folding. To achieve this goal ergonomic and usability tests have been carried out. The tests allowed to find a posture that would ensure efficiency and comfort in the ride to as many users as possible. Parallel tests were made on the vehicle usability in the urban transport system and intermodal. The need for light weight has required special studies on the optimization of the vehicle's architecture and research on super-lightweight materials.     

Experimenting new design languages in contemporary home design

The changes in society at the beginning of this millennium are giving rise to deep transformations in the behavioural trends and tastes of home users, as well as in their lifestyles and consumption patterns. This opens up a wide range of opportunities for innovation within the context of contemporary home design. Due to the emergence of new user profiles, new needs and models are coming to the attention of designers and manufacturing companies. Just think about the new needs resulting from the changing composition of households, new forms of cohabitation and the contemporary multi-ethnic society.     

Ergonomics and sustainability in the design of everyday use products

The relationship between Ergonomics and Design is a key element in the sustainability project, as well as in many other areas of experimental design. In the Design for Sustainability field, Ergonomics is a strategic factor for design culture innovation, providing designers with the necessary knowledge and skills regarding human characteristics and capabilities, as well as user needs and desires during use and interaction with products in work activities and everyday life. Ergonomics is also a strategic innovative factor in design development and manufacturing processes. In fact, ergonomics provides a methodological approach in user-product interaction evaluation processes through the use of participatory design and survey methods, user trials, direct observation, savings and resource conservation, etc.On the other hand, design offers solutions able to interpret user needs and expectations, at the same time suggesting new behaviors and lifestyles.In Design for Sustainability, the ergonomic and user-centered approach contributes greatly to lifestyles and innovative use of products--making it possible to understand and interpret real people needs and expectations in their everyday actions and behavior.New consumption patterns, new awareness of lifestyles, energy source consumption, purchasing methods and consumption style etc. can be supported by design innovation, responding to expressed and unexpressed user needs. With this in mind, the ergonomic approach represents the starting point for design choices and at the same time, a tool for assessing their appropriateness and effectiveness.     

The More the Merrier? The Causal Effect of High Fertility on Later-Life Loneliness in Eastern Europe

Levels of later-life loneliness are high in Eastern Europe. We assess whether having more children is protective against later-life loneliness for Eastern-European mothers and fathers. Drawing on Generations and Gender Surveys data of 25,479 parents aged 50–80 from eight Eastern-European countries, we adopt an instrumental approach exploiting parents’ preference for mixed-sex offspring to estimate the causal effect of having additional children on feelings of loneliness. We find that having an additional child has a causal protective effect against loneliness for mothers. Ordinary least squares regression models also show a weak but statistically significant negative association between number of children and later-life loneliness among fathers. However, results of the instrumental variable analyses are inconclusive for this group. We thus do not find statistically significant causal evidence that having an additional child is protective against loneliness for fathers. Our results underline the importance of addressing reverse causality and selection bias when investigating the links between number of children and later-life loneliness, particularly among women. The causal evidence presented here suggests that the trend towards families with fewer children noted in several Eastern-European countries may place new cohorts of older Eastern-Europeans, and in particular Eastern-European women, at risk of stronger feelings of loneliness.
