Farmers' perceptions of the lay health worker on farms in the Western Cape, South Africa

This study is focussed on farms situated in the Boland health district of the Cape Winelands, South Africa. The aim was to explore, understand, and describe the perceptions of farmers of having a trained lay health worker (LHW) on the farm. A qualitative study design was applied. Data were collected during six in-depth interviews and two focus group discussions with participating farmers. The results show that farmers remained positive about the concept of having a trained LHW on the farm, but became frustrated with the lack of recognition of their and the LHWs' contribution by the public health service. Farmers who are willing to participate and remain active are key to introducing a farm community-based LHW intervention. Sustainable LHW interventions are dependent on public health sector support and recognition of all role players.Farm Management,

First-principles anisotropic constitutive relationships in β-cyclotetramethylene tetranitramine (β-HMX)

First-principles density functional theory calculations have been performed to obtain constitutive relationships in the crystalline energetic material β-cyclotetramethylene tetranitramine (β-HMX). In addition to hydrostatic loading, uniaxial compressions in the directions normal to the {100}, {010}, {001}, {110}, {101}, {011}, and {111} planes have been performed to investigate the anisotropic equation of state (EOS). The calculated lattice parameters and hydrostatic EOS are in reasonable agreement with the available experimental data. The uniaxial compression data show a significant anisotropy in the principal stresses, change in energy, band gap, and shear stresses, which might lead to the anisotropy of the elastic-plastic shock transition and shock sensitivity of β-HMX

The role of risk assessment in reducing homicides by people with mental illness

Background: Improved risk assessment has been stressed as the way to reduce homicides by people with mental illness. The feasibility of predicting rare events needs examining. Aims: To examine the findings of public inquiries into homicides by people with mental illness to see if they support the claim that better risk assessment would have averted the tragedy. Method: Analysis was made of the findings of the public inquiries between 1988 and 1997 in relation to the predictability and preventability of the homicides. Results: Of the homicides considered by the inquiry panels, 27.5% were judged to have been predictable, 65% preventable and 60% of the patients had a long-term history containing violence or substantial risk factors for violence. Conclusions: Improved risk assessment has only a limited role in reducing homicides. More deaths could be prevented by improved mental health care irrespective of the risk of violence. If services become biased towards those assessed as high risk, then ethical concerns arise about the care of both violent and non-violent patients

Theorizing Audience and Spectatorial Agency

This chapter analyses Georgian audiences and spectatorial agency through several lenses: psychoanalytic film theory, theories of the public sphere and of mass publicity, and media studies of cultural convergence. The first section reads Georgian theatre’s heterogeneous playbills as a syntactical rendering of the audience, the imaginary community of the nation in process of negotiation. The second section shows theatrical paratexts blurring the boundary between theatre and coffee house, creating a theatrical public sphere in which the audience exercises daily public agency in saving or damning the play. The third section highlights the mingling of vulnerability and charisma in the celebrity prologue-speaker, a figure who both judges and entrances the audience while also embodying actors’ exposure to possible audience wrath. The final section looks at the theatres’ encouragement of spouting clubs as a means of channelling spectatorial agency

Physical mechanism of anisotropic sensitivity in pentaerythritol tetranitrate from compressive-shear reaction dynamics simulations

We propose computational protocol (compressive shear reactive dynamics) utilizing the ReaxFF reactive force field to study chemical initiation under combined shear and compressive load. We apply it to predict the anisotropic initiation sensitivity observed experimentally for shocked pentaerythritol tetranitrate single crystals. For crystal directions known to be sensitive we find large stress overshoots and fast temperature increase that result in early bond-breaking processes whereas insensitive directions exhibit small stress overshoot, lower temperature increase, and little bond dissociation. These simulations confirm the model of steric hindrance to shear and capture the thermochemical processes dominating the phenomena of shear-induced chemical initiation

The Power of Interfacing Departments in Shaping B2B Customer Satisfaction

Extant research identifies service quality and service encounter perceptions as the key determinants of satisfaction. However, no study in a business-to-business environment has examined the simultaneous effect of these two determinants on overall satisfaction. Hence, we do not know which of these two determinants has a stronger impact on service satisfaction. We investigated this issue by collecting data from shipping managers of several firms in Singapore that used the services of ocean freight shipping companies. Results of path analysis indicate that perceptions of service encounters have a relatively stronger impact compared to service quality. Implications of these results are discussed
