Simulating space-time random fields with nonseparable Gneiting-type covariance functions

Statistics and Computing - Two algorithms are proposed to simulate space-time Gaussian random fields with a covariance function belonging to an extended Gneiting class, the definition of which...     

Children's response to the medical visit for allegations of sexual abuse: maternal perceptions and predicting variables

This study examined maternal perceptions of their child's response to the medical evaluation for alleged sexual abuse. A total of 50 mothers were interviewed 6 months after a visit to a Child Protection Clinic for a medical evaluation of alleged sexual abuse. The mothers answered a questionnaire on their child's reactions to the medical visit. More than 60% of children were perceived as being reassured about physical integrity. The degree of psychological distress was independent of perpetrator's identity and severity of the abuse. Mothers considered that a hypothetical second visit would generate in their child a level of anxiety that increased with perceived intensity of fear of the examination and decreased with perceived kindness of the physician. These results suggest that the physician's behaviour during the medical evaluation for alleged sexual abuse has an influence on the child's degree of distress that is independent of type and severity of abuse.

Tagging for activist ends and strategic ephemerality: creating the Sex Work Database as an activist digital archive

The Sex Work Database project is an interdisciplinary collaboration, currently based in Canada, to research and design digital activist archives of “born digital” and digitized academic research, print and visual media, grassroots activism, and commemorative responses related to missing and murdered women and sex work. This paper discusses the project’s development over its first few years, and discusses the complexities of organizing and representing digital/digitized information using a feminist anti-violence framework. In doing so, we introduce and examine two challenges we have encountered to date: designing a tagging system that expresses the activist frame of the Sex Work Database, and the ethics and efficacy of strategic ephemerality for materials produced by sex worker activists.     

Involving Young People—Empowerment or Exploitation?

The principle that children should be heard as well as seen—that they have a right to be consulted over decisions affecting them and to have their views taken into account by the adults working with or for them—now has general currency. One consequence is that increasing numbers of children and young people are now appearing on conference platforms or are included on the executive councils of charities or participate in working parties. Such events are often effective, but sometimes they can be embarrassing or counter-productive to all concerned. Amanda Allard considers the lessons to be learnt from a successful initiative to involve young people in policy advocacy.     

The impact of organizational culture on men's use of parental leave in Sweden

This article examines the impact of organizational culture on men's usage of parental leave in Sweden, a society that promotes men's sharing of childcare. Results from a mail survey of 317 fathers in six companies suggest that men's use of parental leave is significantly affected by organizational culture, including the company's commitment to caring values, the company's level of 'father friendliness', the company's support for women's equal employment opportunity, fathers' perceptions of support from top managers, and fathers' perceptions of work group norms that reward task performance vs. long hours at work. These effects were independent of the influence of individual- and family-level attributes previously acknowledged to affect men's participation in early childcare. While findings support the social constructionist perspective on gender arrangements, men's advocacy of shared parenting and perception of partners' advocacy of shared leave remained strong independent correlates of leavetaking. Fathers can become agents of change within organizations, as they become more supportive of equal parenthood and as they gain rights to longer periods of parental leave that do not need to be negotiated with mothers. Éste articulo evalúa el impacto de la cultura de organizaciones sobre el uso de la baja por paternidad en Suecia, una sociedad que promueve la involucracion de los hombres en el cuidado de niños. Los resultados de una encuesta por correo de 317 padres de familia en seis empresas sugieren que el uso de la baja por paternidad está afectado por la cultura de la organización, incluido la obligación de la empresa en cuanto a valores humanitarios, el nivel de apoyo a los padres (father friendliness), el apoyo por la igualdad de oportunidades por el empleo de mujeres, las percepciones por parte de los padres del nivel de apoyo desde la gerencia alta, y las percepciones por padres de normas de labores de equipo que recompensan el rendimiento de tareas vs. horas largas de trabajo. Estos efectos eran independientes de la influencia de atributos de individuos y familias que anteriormente han sido reconocido por influir la participación de los hombres en el cuidado de niños pequeños. Mientras los resultados apoyan la perspectiva del construccionismo social, el apoyo de los hombres a la participación conjunta en el cuidado de los niños, y sus percepciones de la medida del apoyo por parte de sus parejas acerca del compartir la baja por paternidad/maternidad quedaron en correlación fuerte con la medida de la baja por paternidad. Los padres pueden hacerse agentes de cambio dentro de las organizaciones, mientras apoyan cada vez más la paternidad/maternidad igual y mientras ganan derechos de periodos de permiso mas largos que no tienen que negociarse con las madres.     

The simulation of industrial robot systems

This paper describes the GRASP computer aided design system for modelling and evaluating industrial robot workplaces. GRASP satisfies a range of simulation needs within the context of designing, implementing and operating industrial robotic systems. The GRASP software may be used to investigate robots operating by themselves or, more likely, as part of an integrated cell. Facilities within GRASP assist workplace layout, position and velocity evaluations, clash detection and co-ordination between items. A robot library exists and is being extended, and an embryo off-line programming facility has been used under restricted conditions. GRASP has been used to help solve a wide range of practical industrial robot problems and has proved itself technically, and also as an educational tool, by showing how a proposed system would operate. The paper describes the facilities within GRASP.
