Infant feeding: the interfaces between interaction design and cognitive ergonomics in user-centered design

This text presents a discussion on the process of developing interactive products focused on infant behavior, which result was an interactive game for encouraging infant feeding. For that, it describes the use of cognitive psychology concepts added to interaction design methodology. Through this project, this article sustains how the cooperative use of these concepts provides adherent solutions to users' needs, whichever they are. Besides that, it verifies the closeness of those methodologies to boundary areas of knowledge, such as design focused on user and ergonomics.     

The amount of ergonomics and user involvement in 151 design processes

Ergonomics, usability and user-centered design are terms that are well known among designers. Yet, products often seem to fail to meet the users' needs, resulting in a gap between expected and experienced usability. To understand the possible causes of this gap the actions taken by the designer during the design process are studied in this paper. This can show whether and how certain actions influence the user-friendliness of the design products. The aim of this research was to understand whether ergonomic principles and methods are included in the design process, whether users are involved in this process and whether the experience of the designer (in ergonomics/user involvement) has an effect on the end product usability. In this study the design processes of 151 tangible products of students in design were analyzed. It showed that in 75% of the cases some ergonomic principles were applied. User involvement was performed in only 1/3 of the design cases. Hardly any correlation was found between the designers' experience in ergonomic principles and the way they applied it and no correlations were found between the designers' experience in user involvement and the users' involvement in the design process.     

Technology and cognitive ability: the use of new technologies and the design of digital interfaces

This study is guided by the principle that there is no technology detached from an ideology. This ideology appears in the interfaces conditioning the relationship between people and digital artifacts. This article adopts as theoretical reference the User-Centered Design (UCD). Under the UCD principles it is presented a key to understand how technology is a vehicle of ideological content that affects the design practices.     

The importance of user centered design methods applied to the design of a new workstation: a case study

This paper presents a case study of the application of user centered design methodologies in the product development for a line of ergonomic office furniture. The study aimed to analyze the experience of using a workstation from the perspective of two groups of users, installers and end users. The observation of users in their natural context of use not only allowed the development team to identify key needs and strategies of the users, transforming them into design solutions, but mainly it warned them of the importance and impact of user involvement in the product development cycle.     

A methodology for connecting user centered design (UCD) with eco-design. The possibility of migration of products to services based on the user acceptance

The consumer products generation is one of the main engines that fuel the planet's environmental problems, reduction of environmental impacts associated with the products has been studied from various aspects between them, the supply of products for public consumption instead of private, seeking to meet the needs of the community by establishing programs for sharing single product. It has been detected a problematic issues linked to this strategy, where the user acceptance of this new way of living together with the products must be achieved. The arguments here presented seek to identify user perception of such proposals and their possible acceptance throughout strategies from the User Centered Design (UCD).     

Consuming the car: anticipation, use and meaning in contemporary youth culture

Drawing on evidence from a recently conducted study of the everyday lives of young people in Manchester, UK, this article considers the place of cars in contemporary youth culture. The article acknowledges the recent beginnings of sociological and social science discussion of cars but concurs with the view that this topic has been much neglected. More specifically the study of young people and personal mobility has been constrained by approaches that emphasise the problematic nature of this phenomena or locate it within a theory of subculture. Taking its cue from recent studies of consumption, this paper offers an alternative theorisation. Refinement of the work on television consumption by Roger Silverstone leads to a discussion of more affluent young people's relationships to cars under three heads: anticipation, use and meaning. It is suggested that car use must be seen in the framework of sociability and networks and that it also critically and suggestively mediates ordinary consumption with imaginative possibilities.     

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 importance of habitat design and aquatic connectivity in amphibian use of urban stormwater retention ponds

Stormwater retention ponds in urbanizing catchments are constructed to collect and treat runoff from impervious surfaces. Amphibians often inhabit retention ponds, which may partly offset the loss of natural wetlands resulting from urbanization. We investigated the use of retention ponds by frogs in a rapidly-urbanizing region of south-eastern Australia to (1) determine the habitat attributes associated with individual species, and (2) recommend specific wetland design criteria to enhance populations of frog species in the region and in other urbanizing areas throughout their distribution. We detected nine species of frogs during calling surveys at 30 retention pond sites in Greater Melbourne, 2008?C2010. There were contrasting differences in habitat associations among five species for which we produced regression models of abundance or occurrence. The mean abundance of Crinia signifera increased with site area, whereas Limnodynastes dumerilii was associated with smaller sites. The occurrence of L. dumerilii was positively associated with waterbody shore depth, whereas L. peronii and L. tasmaniensis were associated with shallow shores. Two species were positively associated with time since construction or since dredging of a site, whereas the occurrence of L. dumerilii decreased with site age. Aquatic vegetation at a site was important for the occurrence of L. peronii and Litoria ewingii. There was evidence for a positive effect of aquatic connectivity on the occurrence of Limnodynastes peronii, which emphasizes the importance of riparian corridors in urban settings. These results highlight the contrasting differences in habitat associations among species in the region. We recommend that retention ponds in our region and elsewhere be constructed or enhanced to include specific habitat attributes that were found to be associated with different amphibian species. We recommend long-term monitoring at sites to determine whether retention ponds augment existing frog populations or contribute to declines.     

The affective politics of hatred: implications for education

This paper argues that using the notion of ambivalence in understanding ethnic hatred can be helpful to educators who struggle to address the pedagogical implications of students’ feelings of hatred. It is suggested that, although hate feelings are difficult to change, unraveling the ambivalence in the affective politics of hatred creates possibilities for enriching educators and students’ perspectives on mutual understanding and solidarity with others. Drawing on insights from an action research project conducted in a higher education institution in the ethnically‐divided Cyprus, the author shows how the notion of hatred as ambivalence constitutes an important step in initiating a subversive analysis.     

Consolidated findings from 6 years research on the age-differentiated design of human-computer interaction

The fast aging of many western and eastern societies and their increasing reliance on information technology create a compelling need to reconsider older users' interactions with computers. This paper summarizes the results of 6 years of research on the age-differentiated design of human-computer interaction. The well-known model of human information processing served as the theoretical framework. The model components 'sensory processing', 'perception', 'working memory', 'decision and response selection' and 'response execution' were analyzed exemplarily in task settings on project management. In seven empirical studies with a total number of 405 participants between 20 and 77 years the human-computer interaction was analyzed regarding effectiveness, efficiency and user satisfaction. For most but not all studies the results reveal that age-induced differences in human-computer interaction can best be compensated by an ergonomic 'design for all'. In some cases however an age-specific approach is favorable.     

The interaction of depersonalization and deindividuation

Abnormal experiences of the self defined here in terms ofdepersonalization may predispose individuals to aggressive behavior in situations that further alter their self-awareness. Conditions that raise self-awareness may inhibit the aggressive behavior of individuals prone to these abnormal experiences of self. In the current research, individuals prone to a distorted body image were least likely to express attitudes reflecting verbal hostility when their self-awareness was raised. Individuals prone to a sense of unreality about others were most likely to express attitudes that reflect physical aggression when their sense of social identity was raised. However, these attitudes were less likely in individuals prone to self-criticism whose social identity was enhanced. The results suggest that a multidimensional construct of depersonalization may aid in the prediction of aggressive behavior that is facilitated by situations that alter the individual’s sense of self.     

Definition of design criteria of mechanical transfer: an interaction between engineering and health areas

This study aims to analyze the factors that justify the low use of a mechanical transfer in the context of a long-term institution. It is a device intended for internal transportation of individuals who have mobility problems. The analysis involves researchers from the fields of health and engineering in order to generate design criteria that consider the needs of caregivers and patients of this institution. To understand the reality of this site and their specificities, was used Ergonomic Work Analysis.     

The war at home: affective economics and transnationally adoptive families in the United States

The question of how to best conduct post-placement interventions for transnationally adoptive families at risk of dissolution (legal annulment) is an emerging issue in the United States. The current popular trend for adoptive families to pursue biomedical post-placement interventions, despite a lack of proof that such interventions actually work to keep the adoptive family intact, suggests the need for a more phenomenological approach to understanding both adoptive parents’ and transnational adoptees’ post-placement experiences. This study examines the empirical experiences of adoptive families at risk of dissolution in the United States who attempt to define and navigate the path toward family stability after adopting. From the coding of this data set emerge some routes through and by which emotions circulate between adoptive parents and transnational adoptees through the family body and the family social. Particularly, it investigates one post-placement “affective economy” at work in which adoptive parents attempt, through the expression of particular forms of parental love, to align adoptees as subjects of the private, nuclear American family, while adoptees more often attempt to create space for more heterogeneous forms of family, ones that include birth parents and other kin-like relations in their countries of origin. Ultimately, it illuminates some vastly different and sometimes contradictory ways that adoptive parents and adoptees can interpret family through emotional lenses, ones that can prevent a smooth post-placement transition for adoption actors. An understanding of these differences and how they shape, and are shaped by, the post-placement affective economy within families at risk of dissolution may aid in locating indicators for adoption dissolution, and possibly, designing more effective post-placement interventions for families struggling in the aftermath of adoption. It may also help scholars begin to think about the construction and impact of affective economies in the realm of adoption more generally.     

Explorations in immediacy: The nonverbal system and its relationship to affective and situational factors

Male college students interacted with a male confederate while the context of the interaction, gaze behaviors of the confederate and the perceived source of the subject's arousal were manipulated. The dependent variables included nonverbal behaviors, affective reactions and perceptions of and liking for the confederate. The study was conducted to provide more information about the relationship among the nonverbal immediacy behaviors and the relevance of several situational variables to each of these behaviors. In addition, there was an examination of Patterson's 1976 contention that the evaluation of the individual's state of arousal determines the reciprocation or compensation of nonverbal intimacy. The data analysis revealed a system of weakly related immediacy behaviors strongly related to the subjects' affective states. A general dominance factor emerged that was related to several nonverbal behaviors and it was confirmed that arousal was related to both nonverbal behavior and interpersonal attraction. It seemed doubtful, however, that this relationship was as straightforward as Patterson's model predicted. The results are discussed in light of problems specific to this area of research.This experiment was based on a portion of a doctoral dissertation carried out by the first author at the University of Maine at Orono.The authors would like to acknowledge the help of the following people who served as observers and/or confederates: Charlotte Bailey, Vicki Choate, Gail Deabay, Mark Himelfarb, Maryjo McAndrew, Brad Peters and Tom Waite.     

The differential use of metaphor in psychotherapy

Metaphor is seen to play a significant role in psychoanalytic theory and technique. While acknowledging this view, this paper examines the differences in which individuals of varying developmental profiles, experience, comprehend and use metaphor in the context of psychotherapy. Differences in the capacity to play, adaptively regress, regulate affect, maintain ego boundaries, and symbolize, are found to affect capacities to employ those figures of speech in words or phrases literally denoting one type of object or idea but used in place of others by suggesting likenesses or analogies. A rationale for differential use of interventions involving metaphor is offered.
