Pesticide exposure and sprayer design: ergonomics evaluation to reduce pesticide exposure

Plant protection products are used in agriculture to improve yields, but this use can cause contamination of the environment and is also likely to have adverse short and long term effects on agricultural workers. This poster describes a systems approach to reducing the risk of operator exposure to plant protection products through the introduction of ergonomics to the design process of large agricultural sprayers.     

A two-sample parametric group sequential procedure for monitoring clinical trials

A group sequential procedure is presented which allows for staggered entry of patients, random loss to followup, and utilizes the flexible boundary approach of Lan and DeMets. The proposed procedure assumes that response times are nearly exponentially distributed. An example as well as simulation studies comparing the performance of the proposed procedure with the group sequential logrank are also presented.     

Bayesian analysis of human movement curves

Summary.  We consider the Bayesian analysis of human movement data, where the subjects perform various reaching tasks. A set of markers is placed on each subject and a system of cameras records the three-dimensional Cartesian co-ordinates of the markers during the reaching movement. It is of interest to describe the mean and variability of the curves that are traced by the markers during one reaching movement, and to identify any differences due to covariates. We propose a methodology based on a hierarchical Bayesian model for the curves. An important part of the method is to obtain identifiable features of the movement so that different curves can be compared after temporal warping. We consider four landmarks and a set of equally spaced pseudolandmarks are located in between. We demonstrate that the algorithm works well in locating the landmarks, and shape analysis techniques are used to describe the posterior distribution of the mean curve. A feature of this type of data is that some parts of the movement data may be missing—the Bayesian methodology is easily adapted to cope with this situation.     

Cleveland 20 years on: themes of disruption and repair in the trauma narratives of children,adults and society

This is the second of two linked papers which explores coherent and incoherent narratives emerging from Cleveland. It draws a parallel between the disrupted narratives of child and adult survivors of child sexual abuse and professional and societal narratives of Cleveland. The paper looks at the therapeutic task of individual repair using attachment‐based therapy, illustrated by clinical examples. It identifies five key challenges relevant to repair in the interpersonal, intra‐personal and societal domains. Copyright © 2008 John Wiley & Sons, Ltd.     

'White Men are Liars' - another look at Aboriginal-Western interactions

Aboriginal Australia has been in the national press lately fortragic reasons. Family violence, substance abuse, unemployment,poor health, appalling living conditions, hopelessness –the statistics and stories tell a terrible tale of life in someremote area communities. Although they do not describe all Indigenouscommunities, they are a reality for a sufficiently large numberto require a radical rethink of policies designed to promoteIndigenous rights and prosperity. They exist despite structuralreforms previously achieved and believed to rectify the wrongsof the past, such as land rights, government financial support,educational     

School performance, academic aspirations, and drug use among children and adolescents

The relationship between drug use, school performance, and academic aspirations among 446 Anglo and Hispanic youths, age nine to seventeen, is explored. Two groups of subjects--current substance users and non-users--were interviewed. Subjects in each comparison group were similar in age, ethnicity, and gender. Overall results, consistent with prior research, indicate a significant relationship between current school performance, future educational aspirations, and drug use. No difference was noted between substance use groups on indicators of general interest in school work or probability of dropping out of school. Important differences in response patterns occurring with age, ethnicity, and gender were found.     

Police interviews with vulnerable people alleging sexual assault: Probing inconsistency and questioning conduct

Reporting sexual assault to the authorities is fraught with difficulties, and these are compounded when the complainant is hindered by an intellectual disability (ID). In a study of 19 U.K. police interviews with complainants with ID alleging sexual assault and rape, we found that most interviewing officers on occasion pursued lines of questioning which not only probed inconsistencies (which is mandated by their guidelines), but implicitly questioned complainants’ conduct (which is not). We detail two main conversational practices which imply disbelief and disapproval of the complainants’ accounts and behaviour, and whose pragmatic entailments may pose problems for complainants with ID. Such practices probably emerge from interviewers’ foreshadowing of the challenges likely to be made in court by defence counsel. As a policy recommendation, we suggest providing early explanation for the motivation for such questioning, and avoiding certain question formats (especially how come you did X? and why didn't you do Y?).     

Inter-agency Information Sharing in Health and Social Care Services: The Role of Professional Culture

This article uses a literature review to examine the ways inwhich professional culture might shape inter-organizationalexchange of personal information in a health and social carecontext. The aim is to explore a simplified model of possibleinformation-sharing behaviours (‘ideal’, ‘over-open’,‘over-cautious’ and ‘chaotic’) and tosuggest that patterns of information sharing may be influencedby a number of factors. It is proposed that these factors includenot only inter-professional differences in the approach takento information sharing but also the ways in which the professionsinterrelate.     

Partnership Working in Public Policy Provision: A Framework for Evaluation

Partnership working has emerged as a key feature of New Labour's approach to social policy. However, although the theoretical benefits of partnership have been well rehearsed, agencies charged with fostering partnerships lack "evidence" about how best to proceed in bringing about organizational change. This paper describes the development and implementation of a practical approach to capturing the strategies that can be used to establish, strengthen and sustain local partnerships. To this end, it presents a conceptual framework for the evaluation of partnership working and demonstrates the application of the framework to an investigation of partnership working in Cornwall and Isles of Scilly, and Plymouth Health action zones.     

Measuring the Dynamics of Interactional Synchrony

Past research has revealed that natural social interactions contain interactional synchrony. The present study describes new methods for measuring interactional synchrony in natural interactions and evaluates whether the behavioral synchronization involved in social interactions is similar to dynamical synchronization found generically in nature. Two methodologies, a rater-coding method and a computational video image method, were used to provide time series representations of the movements of the co-actors as they enacted a series of jokes (i.e., knock?Cknock jokes). Cross-spectral and relative phase analyses of these time series revealed that speakers?? and listeners?? movements contained rhythms that were not only correlated in time but also exhibited phase synchronization. These results suggest that computational advances in video and time series analysis have greatly enhanced our ability to measure interactional synchrony in natural interactions. Moreover, the dynamical synchronization in these natural interactions is commensurate with that found in more stereotyped tasks, suggesting that similar organizational processes constrain bodily activity in natural social interactions and, hence, have implications for the understanding of joint action generally.
