    Evaluating Race-of-Interviewer Effects In a National Survey

    Abstract: The present article attempts to overcome some of the problems involved in estimating race-of-interviewer effects in a nonexperimental national survey. Individual items as well as scales were examined, using General Social Survey (GSS) data. Race-of-interviewer effects large enough to justify the practice of matching interviewer and respondent race for interviews on racial topics were found for both black and white respondents. A few such effects were found for nonracial items among blacks, but the range of items involved is smaller than what has been reported in previous studies. The impact of race-of-interviewer effects on mean estimates in the GSS appears to be small for white respondents, due to the small proportion of cross-race interviews. The proportion of cross-race interviews among blacks is larger and more variable over the years, and the impact of race-of-interviewer effects should be considered when analyzing items which show these effects.

    Comparison of object-level grasp controllers for dynamic dexterous manipulation
    SAGE Publications ; 2012
    In:  The International Journal of Robotics Research Vol. 31, No. 1 ( 2012-01), p. 3-23

    Abstract: Object-level control of a dexterous robot hand provides an intuitive high-level interface to solve fine manipulation tasks. In the past, many algorithms were proposed based on a weighted pseudoinverse of the grasp map. In a different approach, Stramigioli introduced a virtual-object based controller – called an Intrinsically Passive Controller (IPC). These controllers are reviewed and compared. A new controller that is similar to the IPC but using a virtual frame rather than a virtual object is subsequently proposed. The controllers are compared with respect to their object force distribution, the extendability to N fingers, the ease of specifying the object-level impedance and grasp forces, the dimensionality of the coupling springs, the internal controller dynamics, and the computational effort. Controllers for robotic hands usually implement only stiffness controllers and do not program the damping. We address how to choose and implement damping as a function of the desired object-level stiffness and the effective hand–object inertia. The evaluation reveals the dynamic effects of fast motions, which should not be neglected for the design of grasp controllers in practice. The application of the controllers to the torque-controlled DLR Hand II is employed to compare their effectiveness in experiments.

    Estimating Nonresponse and Response Bias : Resident and Nonresident Parents' Reports about Child Support

    Abstract: Although researchers are aware that nonresponse and response bias may compromise the accuracy of estimates from survey data, it is difficult to obtain estimates of these biases. In this article, we estimate nonresponse and response bias for a particular case—child support awards and payments. The sample of divorced resident and nonresident parents was drawn from Wisconsin court records and subsequently interviewed by telephone in 1987. The court records provide the criterion to use in estimating nonresponse and response bias. The analysis shows that those not interviewed are less likely to have awards or to pay support than participants, and the average award and average amount paid are lower for them than for survey participants. Both resident mothers and nonresident fathers overreport the amount of support owed and paid, but the bias is larger for fathers. Nonparticipation bias is greater for measures of paying support than for measures of owing support. Response bias contributes more to total nonsampling bias than does nonparticipation bias for reports of amounts of support owed and paid (including direct payments). Only for resident mothers' reports of the amount paid (omitting direct payments) is the total nonsampling bias less than 3 times the standard error.

    On making robots understand safety: Embedding injury knowledge into control

    Abstract: Enabling robots to safely interact with humans is an essential goal of robotics research. The developments achieved over recent years in mechanical design and control made it possible to have active cooperation between humans and robots in rather complex situations. For this, safe robot behavior even under worst-case situations is crucial and forms also a basis for higher-level decisional aspects. For quantifying what safe behavior really means, the definition of injury, as well as understanding its general dynamics, are essential. This insight can then be applied to design and control robots such that injury due to robot–human impacts is explicitly taken into account. In this paper we approach the problem from a medical injury analysis point of view in order to formulate the relation between robot mass, velocity, impact geometry and resulting injury qualified in medical terms. We transform these insights into processable representations and propose a motion supervisor that utilizes injury knowledge for generating safe robot motions. The algorithm takes into account the reflected inertia, velocity, and geometry at possible impact locations. The proposed framework forms a basis for generating truly safe velocity bounds that explicitly consider the dynamic properties of the manipulator and human injury.

    Requirements for Safe Robots: Measurements, Analysis and New Insights

    Abstract: Physical human—robot interaction and cooperation has become a topic of increasing importance and of major focus in robotics research. An essential requirement of a robot designed for high mobility and direct interaction with human users or uncertain environments is that it must in no case pose a threat to the human. Until recently, quite a few attempts were made to investigate real-world threats via collision tests and use the outcome to considerably improve safety during physical human—robot interaction. In this paper, we give an overview of our systematic evaluation of safety in human—robot interaction, covering various aspects of the most significant injury mechanisms. In order to quantify the potential injury risk emanating from such a manipulator, impact tests with the DLR-Lightweight Robot III were carried out using standard automobile crash test facilities at the German Automobile Club (ADAC). Based on these tests, several industrial robots of different weight have been evaluated and the influence of the robot mass and velocity have been investigated. The evaluated non-constrained impacts would only partially capture the nature of human—robot safety. A possibly constrained environment and its effect on the resulting human injuries are discussed and evaluated from different perspectives. As well as such impact tests and simulations, we have analyzed the problem of the quasi-static constrained impact, which could pose a serious threat to the human even for low-inertia robots under certain circumstances. Finally, possible injuries relevant in robotics are summarized and systematically classified.

    Boundary-Value Problems for Hyperbolic Equations Related to Steady Granular Flow

    Abstract: Boundary value problems for steady-state flow in elastoplasticity are a topic of mathematical and physical interest. In particular, the underlying PDE may be hyperbolic, and uncertainties surround the choice of physically appropriate stress and velocity boundary conditions. The analysis and numerical simulations of this paper address this issue for a model problem, a system of equations describing antiplane shearing of an elastoplastic material. This system retains the relevant mathematical structure of elastoplastic planar flow. Even if the flow rule is associative, two significant phenomena appear: (i) For boundary conditions suggestive of granular flow in a hopper, in which it seems physically natural to specify the velocity everywhere along a portion of the boundary, no such solutions of the equations exist; rather, we construct a solution with a shear band (velocity jump) along part of the boundary, and an appropriate relaxed boundary condition is satisfied there. (ii) Rigid zones appear inside deforming regions of the flow, and the stress field in such a zone is not uniquely determined. For a nonassociative flow rule, an extreme form of nonuniqueness—both velocity and stress—is encountered.

    Abstract: Child sexual abuse (CSA) is a serious public health problem that increases risk for physical and mental health problems across the life course. Young adolescents are responsible for a substantial portion of CSA offending, yet to our knowledge, no validated prevention programs that target CSA perpetration by youth exist. Most existing efforts to address CSA rely on reactive criminal justice policies or programs that teach children to protect themselves; neither approach is well validated. Given the high rates of desistance from sexual offending following a youth’s first CSA-related adjudication, it seems plausible that many youth could be prevented from engaging in their first offense. The goal of this article is to examine how school-based universal prevention programs might be used to prevent CSA perpetrated by adolescents. We review the literature on risk and protective factors for CSA perpetration and identify several promising factors to target in an intervention. We also summarize the literature on programs that have been effective at preventing adolescent dating violence and other serious problem behaviors. Finally, we describe a new CSA prevention program under development and early evaluation and make recommendations for program design characteristics, including unambiguous messaging, parental involvement, multisession dosage, skills practice, and bystander considerations.

    Sex Trafficking as the ‘New Slave Trade’?

    Abstract: This article analyzes the United Nation’s media branding of sex trafficking as the ‘New Slave Trade’. The association of forced sex with migrant women as slavery galvanizes a broad contingency against trafficking and broadens the power of the state to intervene in sexual activity under the jurisdiction of national security. Under the guise of national security, the media campaigns’ focus on slavery moralizes stronger border protection and the surveillance of migrants in order to prevent criminal networks and regimes of slavery from penetrating the pure boundaries of the USA nation-state.
