Mental Rotation of Dynamic,Three‐Dimensional Stimuli by 3‐Month‐Old Infants

Mental rotation involves transforming a mental image of an object so as to accurately predict how the object would look if it were rotated in space. This study examined mental rotation in male and female 3‐month‐olds, using the stimuli and paradigm developed by Moore and Johnson (2008) . Infants were habituated to a video of a three‐dimensional object rotating back and forth through a 240° angle around the vertical axis. After habituation, infants were tested both with videos of the same object rotating through the previously unseen 120° angle, and with the mirror image of that display. Unlike females, who fixated the test displays for approximately equal durations, males spent significantly more time fixating the familiar object than the mirror‐image object. Because familiarity preferences like this emerge when infants are relatively slow to process a habituation stimulus, the data support the interpretation that mental rotation of dynamic three‐dimensional stimuli is relatively difficult—but possible—for 3‐month‐old males. Interpretation of the sex differences observed in 3‐ and 5‐month‐olds’ performances is discussed.     

Telling a Good Story: Using Narratives in Vocational Rehabilitation With Veterans

Because of the high chronicity of work-related problems in a Veterans Administration Medical Center population, many of the traditional methods of career assessment, counseling, and placement have proven ineffectual. In this article the authors detail the development of an intervention based on narrative or storytelling principles. They describe efforts to introduce this model to patients as well as to relate patients' stories to vocational outcomes. The usefulness of stories as an organizing principle for counselors and clients is discussed, and suggestions are offered for further uses of storytelling interventions.     

Models of social mobility

Properties of measures and models of social mobility are analyzed in relation to the conceptualization of mobility. Two main objectives of mobility research are identified. One is the study of determinants of occupational achievement, the other is the study of mobility as a characteristic of social systems. It is shown that the realization of both objectives is hindered by a failure of commonly used models and measures of mobility to separate out the various individual and structural factors responsible for mobility.     

Bourdieu and the Logic of Practice: Is All Giving Indian-Giving or is "Generalized Materialism" Not Enough? For the memory of Louis Dumont

I argue here that in the end Bourdieu's theory of practice fails to overcome the problem on which it expressly centers, namely, subject-object dualism. The failure is registered in his avowed materialism, which, though significantly "generalized," remains what it says: a materialism. In order to substantiate my criticism, I examine for their ontological presuppositions three areas of his theoretical framework pertaining to the questions of (1) human agency (as seen through the conceptual glass of the habitus), (2) otherness, and (3) the gift. By scrutinizing Bourdieu's powerful and progressive social theory, with an eye to finding fault, I hope to show the need to take a certain theoretical action, one that is patently out of keeping with the usual self-presentation and self-understanding of social science. The action I have in mind is this: because the problem of subject-object dualism is in the first place a matter of ontology, in order successfully to address it there must take place a direct shift of ontological starting point, from the received starting point in Western thought to one that projects reality in terms of ambiguity that is basic. With this shift the dualism of subject and object dissolves by definition, leaving a social reality that, for reasons of its basic ambiguity, is best approached as a question of ethics before power.     

Making the Randomized Response Technique Work

The ability of the randomized response technique to obtain sensitiveinformation on surveys was compared to two other methods involvingself-administered questionnaires. Using a national probabilitysample, and extending upon a number of developmental changeswhich have evolved over the years, the randomized response techniqueproved to be decidedly superior to the other methods.     

‘My dad hangs out of helicopter doors and takes pictures of oil platforms': Children's accounts of parental work in the oil and gas industry

Against the backdrop of the acceleration in pace of work and family life over the last decade, and the accompanying intensification of the work-family debate, this paper argues for the need to include children as stakeholders in the work-family debate. The ethnographic study on which this paper is based brings together children, family, work and community to explore interrelationships between workplace change, parental employment and family life in the oil and gas industry in Scotland. This paper focuses specifically on children's accounts of parental work and the work-family interface. Children, aged 8-12, were seen in schools and at home. Eight focus groups were conducted in two primary schools with 33 children. Nineteen of the families of these children participated in follow-up home interviews, in which 21 focus group children and a further 21 children (siblings, cousins and friends) were seen at home. Multiple methods were used: pictures and photographs of 'work', drawings, a poem, vignettes, word games, and a 'life mode technique'. The paper discusses children's concepts of 'work'; children's knowledge of parental work and the oil industry; children's perceptions of the impact of work on their parents; children's accounts of the effects of parental work on them and the importance of 'family time'; children's own work aspirations; and children's views and values about involvement, communication and decision making regarding parental work. Similarities and differences between children's accounts are highlighted. Sobre el telón de fondo del aumento de paso del trabajo y de la vida familiar en esta última década, y la intensificación del debate 'trabajo/familia' que lo acompaña, este artículo aboga por lo necesidad de incluir a los niños como partes interesadas en tal debate. El estudio etnográfico sobre el cual se basa este artiículo reune a los niños, la familia, el trabajo y la comunidad para explorar las interrelaciones entre el cambio de lugar del trabajo, el empleo de los padres y la vida familiar en la industria petrolera y del gas natural en Escocia. Este artículo se centra específicamente en las cuentas de unos niños del trabajo de los padres y de la interrelación entre el trabajo y la familia. Se entrevistaron a unos niños de 8—12 anos de edad en la escuela y en casa. Se realizaron ocho grupos de enfoque con 33 niños en dos escuelas de estudios primarios. De las familias de estos niños, 19 participaron en entrevistas de seguimiento, en las cuales 21 niños de los grupos de enfoque y 21 niños más (hermanos, primos y amigos,) fueron entrevistados en casa. Se emplearon múltiples métodos: ilustraciones y fotografías de ‘trabajo', dibujos, un poema, estampas, juegos con palabras y una ‘técnica modo de vida'. El artículo trata de los conceptos de los niños del trabajo; los conocimientos de los niños del trabajo de los padres y de la industria petrolera; las percepciones de los niños del efecto del trabajo en sus padres; las cuentas de los niños de los efectos del trabajo de los padres en los mismos niños y de la importancia del ‘tiempo para la familia'; las propias aspiraciones del los niños acerca del trabajo; y los puntos de vista y los valores de los niños sobre la participación, la comunicación y la toma de decisiones acerca del trabajo de los padres. Se ponen del relieve los elementos en común y las diferencias entre las cuentas de los niños.     

Multimedia in manufacturing

Multimedia is promoted as the technology for the future from the perspective of applications and its role in improving enterprise integration and management effectiveness. As yet few useful applications are found in business and manufacturing. Nevertheless, a growing number of businesses are looking to multimedia for real-life business solutions. Computerized production management systems have enjoyed the same growth and popularity as the personal computers and workstations on which they run. The application of multimedia in various functional areas of manufacturing such as marketing, design and engineering, production and distribution has tremendous potential, taking into account its capacity to integrate text, drawings, full-vector graphics, and full-motion video. Multimedia can also be used as an open development framework for manufacturing applications, especially in CAD, CAE and CAM, by providing users with tools to re-engineer and integrate product and process information. Advances in telecommunications and associated technological developments. Like the personal communicator and the video phone will increasingly add to the importance of multimedia in modern manufacturing. In addition, the future of manufacturing depends crucially on a well-trained employee base. Consequently, interactive video-based training programs appear ideal for jobs that have a high level of human error. In factories, computers and interactive video have been widely used. Realizing the importance of multimedia in manufacturing, especially in the process of enterprise integration and integrating the functional areas of manufacturing, an attempt has been made to investigate the applications of multimedia and identify some future research directions.
