Behold the Beasts Beside You: The Adaptation and Alteration of Animals in LXX-Job
âBehold the beasts beside you; they eat grass like cattleâ (LXX-Job 40:15). The first translator for the book of Job into Greek was faced with a difficult text, replete with archaisms, corruptions, and convoluted Hebrew. He produced a distinctive â and often misunderstood â translation. Though its central characteristic is one of omission, its general approach to the text has proven hard to categorize. This study continues this trend by following one feature of Job that a casual reader cannot overlook: the book of Jobâs zoological panoply. The LXX-translator handles these creatures in a variety of ways, often contextually-sensitive and quite creative. Furthermore, he brings in external material, from other LXX books and Greek literature, to translate other passages. Most surprisingly, he displays a remarkably âinclusiveâ approach to canonicity and âexclusiveâ ideas about animals and wisdom. At the end, the individual character of the translator is much more visible in the translation than what it would appear at first. âBeholding the beastsâ in LXX-Job tells us as much about the translator as the translation itself
Investigating patient acceptability of stratified medicine for schizophrenia : a mixed methods study
Background
Health services have advocated a stratified medicine approach in mental health, but little is known about whether service users would accept this approach.
Aims
To explore service usersâ views of the acceptability of stratified medicine for treatment-resistant schizophrenia compared to the traditional âtrial-and-errorâ approach.
Methods
A mixed methods observational study that explored questionnaire responses on acceptability and whether these responses were affected by demographic or clinical variables. We also investigated whether treatment responsiveness or experience of invasive tests (brain scans and blood tests) affected participantsâ responses. Questionnaire generated qualitative data were analyzed thematically. Participants (N108) were aged 18â65, had a diagnosis of schizophrenia, and were adherent to antipsychotic medication.
Results
Acceptability of a stratified approach was high, even after participants had experienced invasive tests. Most rated it as safer (62% vs 43%; P < .01 [CI: â1.69 to 2.08]), less risky (77% vs 44%; P < .01 [CI: â1.75 to 1.10]), and less painful (90% vs 73%; P < 0.01 [CI: â0.84 to 0.5]) and this was not affected by treatment responsiveness or test experience. Although not statistically significant, treatment nonresponders were more willing to undergo invasive tests. Qualitatively, all participants raised concerns about the risks, discomfort, and potential side effects associated with the invasive tests.
Conclusions
Service users were positive about a stratified approach for choosing treatments but were wary of devolving clinical decisions to purely data-driven algorithms. These results reinforce the value of service user perspectives in the development and evaluation of novel treatment approaches
Measurement of the cosmic ray spectrum above eV using inclined events detected with the Pierre Auger Observatory
A measurement of the cosmic-ray spectrum for energies exceeding
eV is presented, which is based on the analysis of showers
with zenith angles greater than detected with the Pierre Auger
Observatory between 1 January 2004 and 31 December 2013. The measured spectrum
confirms a flux suppression at the highest energies. Above
eV, the "ankle", the flux can be described by a power law with
index followed by
a smooth suppression region. For the energy () at which the
spectral flux has fallen to one-half of its extrapolated value in the absence
of suppression, we find
eV.Comment: Replaced with published version. Added journal reference and DO
Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger
Observatory and is used to detect the radio emission of cosmic-ray air showers.
These observations are compared to the data of the surface detector stations of
the Observatory, which provide well-calibrated information on the cosmic-ray
energies and arrival directions. The response of the radio stations in the 30
to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of
the incoming electric field. For the latter, the energy deposit per area is
determined from the radio pulses at each observer position and is interpolated
using a two-dimensional function that takes into account signal asymmetries due
to interference between the geomagnetic and charge-excess emission components.
The spatial integral over the signal distribution gives a direct measurement of
the energy transferred from the primary cosmic ray into radio emission in the
AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air
shower arriving perpendicularly to the geomagnetic field. This radiation energy
-- corrected for geometrical effects -- is used as a cosmic-ray energy
estimator. Performing an absolute energy calibration against the
surface-detector information, we observe that this radio-energy estimator
scales quadratically with the cosmic-ray energy as expected for coherent
emission. We find an energy resolution of the radio reconstruction of 22% for
the data set and 17% for a high-quality subset containing only events with at
least five radio stations with signal.Comment: Replaced with published version. Added journal reference and DO
Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy
We measure the energy emitted by extensive air showers in the form of radio
emission in the frequency range from 30 to 80 MHz. Exploiting the accurate
energy scale of the Pierre Auger Observatory, we obtain a radiation energy of
15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV
arriving perpendicularly to a geomagnetic field of 0.24 G, scaling
quadratically with the cosmic-ray energy. A comparison with predictions from
state-of-the-art first-principle calculations shows agreement with our
measurement. The radiation energy provides direct access to the calorimetric
energy in the electromagnetic cascade of extensive air showers. Comparison with
our result thus allows the direct calibration of any cosmic-ray radio detector
against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version. Added journal reference and DOI.

Positive and negative effects of antipsychotic medication: an international online survey of 832 recipients
Background: Antipsychotic medication is currently the treatment of choice for psychosis, but few studies directly survey the first hand experience of recipients.
Objectives: To ascertain the experiences and opinions of users of an international sample of antipsychotic drugs regarding positive and negative effects.
Method: An online direct-to-consumer questionnaire was completed by 832 users of antipsychotics, from 30 countries â predominantly USA, UK and Australia. This is the largest such sample to date.
Results: Over half (56%) thought the drugs reduced the problems they were prescribed for, but 27% thought they made them worse. Slightly less people found the drugs generally âHelpfulâ (41%) than found them âUnhelpfulâ (43%). While 35% reported that their âquality of lifeâ was âimprovedâ, 54% reported that it was made âworseâ. The average number of adverse effects reported was 11, with an average of five at the âsevereâ level. Fourteen effects were reported by 57% or more participants, most commonly: âDrowsiness, feeling tired, sedationâ (92%), âLoss of motivationâ (86%), âSlowed thoughtsâ (86%), and âEmotional numbingâ (85%). Suicidality was reported to be a side effect by 58%. Older people reported particularly poor outcomes and high levels of adverse effects. Duration of treatment was unrelated to positive outcomes but significantly related to negative outcomes. Most respondents (70%) had tried to stop taking the drugs. The most common reasons people wanted to stop were the side effects (64%) and worries about long-term physical health (52%). Most (70%) did not recall being told anything at all about side effects.
Conclusions Clinical implications are discussed, with a particular focus on the principles of informed consent, and involving patients in decision making about their own lives
Assessing the Impact and Effectiveness of Hearing Voices Network Self-Help Groups
The Hearing Voices Network (HVN) is an influential service-user led organisation that
promotes self-help as an important aspect of recovery. This study presents the first systematic
assessment of the impact and effectiveness of HVN self-help groups. A customized 45-item
questionnaire, the Hearing Voices Groups Survey, was sent to 62 groups affiliated with the
English HVN. 101 responses were received. Group attendance was credited with a range of
positive emotional, social and clinical outcomes. Aspects that were particularly valued
included: opportunities to meet other voice hearers, provision of support that was unavailable
elsewhere, and the group being a safe and confidential place to discuss difficult issues.
Participants perceived HVN groups to facilitate recovery processes and to be an important
resource for helping them cope with their experiences. Mental health professionals can use
their expertise to support the successful running of these groups
Identification of CD4+ T Cell Epitopes in C. burnetii Antigens Targeted by Antibody Responses
Coxiella burnetii is an obligate intracellular Gram-negative bacterium that causes acute Q fever and chronic infections in humans. A killed, whole cell vaccine is efficacious, but vaccination can result in severe local or systemic adverse reactions. Although T cell responses are considered pivotal for vaccine derived protective immunity, the epitope targets of CD4+ T cell responses in C. burnetii vaccination have not been elucidated. Since mapping CD4+ epitopes in a genome with over 2,000 ORFs is resource intensive, we focused on 7 antigens that were known to be targeted by antibody responses. 117 candidate peptides were selected from these antigens based on bioinformatics predictions of binding to the murine MHC class II molecule H-2 IAb. We screened these peptides for recognition by IFN-Îł producing CD4+ T cell in phase I C. burnetii whole cell vaccine (PI-WCV) vaccinated C57BL/6 mice and identified 8 distinct epitopes from four different proteins. The identified epitope targets account for 8% of the total vaccination induced IFN-Îł producing CD4+ T cells. Given that less than 0.4% of the antigens contained in C. burnetii were screened, this suggests that prioritizing antigens targeted by antibody responses is an efficient strategy to identify at least a subset of CD4+ targets in large pathogens. Finally, we examined the nature of linkage between CD4+ T cell and antibody responses in PI-WCV vaccinated mice. We found a surprisingly non-uniform pattern in the help provided by epitope specific CD4+ T cells for antibody production, which can be specific for the epitope source antigen as well as non-specific. This suggests that a complete map of CD4+ response targets in PI-WCV vaccinated mice will likely include antigens against which no antibody responses are made
