Reflections on myth and history : Tuareg concepts of truth, "Lies," and "Children's Tales"
In this essay, I discuss the problem of how to interpret these processes without imposing Western paradigms and "black-box" terms, and yet still produce useful comparisons of different knowledge-power systems. My purpose is to discuss the problematics of Western-derived classifications and lenses used in describing and interpreting knowledge and power systems. For example, essentialist categories such as "myth," "history," "science," and "art," as well as "sacred" and "secular" domains, are of limited value as a measure in crosscultural comparison, since they are derived from a Western episteme. Tuareg categories, I argue, need to be analyzed in relation to local social and epistemological distinctions./
Steady-State and Time-Resolved Spectroscopy of F420 Extracted from Methanogen Cells
The methanogen electron carrier F420 was extracted from a methanogen cell culture, Methanobrevibacter ruminantium, and separated from other cell components by a single anion exchange chromatographic process. The extent of separation was determined spectroscopically. The fluorescence lifetime of F420 at pH 7.5 is ~4.2 nanoseconds
Tetrapotassium cis-dioxido-trans-bis(sulfato-κO)sulfato(κ2 O,O′)molybdate(VI)
The title compound, K4[MoVIO2(SO4)3], was precipitated from a melt of molybdenum(VI) oxide and potassium sulfate in potassium disulfate. The compound contains monomeric [MoVIO2(SO4)3]4− anions, with the MoVI atom, both oxide ligands, and the S atom and both ligating O atoms of the bidentate sulfate group lying on a crystallographic mirror plane. One of the potassium cations is nine-coordinate, while the other is eight-coordinate
Desire for control and the integrated motivational-volitional model of suicidal behavior : results from a pilot investigation of adults in the United Kingdom
Background: Suicidal behavior remains a pressing problem in the United Kingdom. Continued theory development is a critical step toward designing effective prevention. Aims: The present study tested a novel element to suicide theory, the Desire for Control, for its direct and moderating roles within the Integrated Motivational-Volitional (IMV) Model of Suicidal Behavior. Method: An online-administered cross-sectional suicide risk survey study (n=116) was conducted among adults living in the United Kingdom. Results: Mean suicidal ideation scores were in the non-clinical range. DOC Leadership and Destiny Control were associated with good mental health. DOC Decision Avoidance was associated with poor mental health. DOC Decision Avoidance also acted as a motivational moderator in which the entrapment-suicidal thinking link was worse among those high in decisional avoidance. Conclusion: DOC represents a novel, valuable addition to suicide theory and may inform suicide-specific psychotherapeutic intervention. Additional research is needed to full understand the role of DOC and its factor structures in the IMV
Prevalence of Posterior Shoulder Subluxation in Children With Neonatal Brachial Plexus Palsy After Early Full Passive Range of Motion Exercises
BackgroundChildren with neonatal brachial plexus palsy (NBPP) are often prescribed shoulder range of motion (ROM) exercises; however, the extent and timing of exercise implementation remains controversial in the context of shoulder joint integrity. The association of ROM exercises to delayed posterior shoulder subluxation (PSS) is unknown.ObjectiveTo determine prevalence of PSS in children with NBPP who began full passive ROM exercises before 6 months of age, and characteristics associated with development or absence of PSS in children.DesignCrossâ sectional study.SettingTertiary care NBPP referral center.ParticipantsFortyâ six children with NBPP, aged 24â 57 months, who began full ROM exercises before 6 months of age.MethodsOne radiologist conducted bilateral shoulder ultrasound (US) on each child to evaluate for PSS. One occupational therapist evaluated each child clinically for PSS using defined parameters without knowledge of US results.Main Outcome MeasuresBy US, 20% of children had PSS; 46% had PSS by clinical examination. Shoulder active ROM limitations and history of shoulder surgery were associated with presence of PSS. Extent of NBPP was not associated with PSS.ResultsNine of 46 children (20%) met US criteria for PSS; α angle was 58° ± 21° (mean ± standard deviation [SD]). Twentyâ one children (46%) met clinical criteria. Mean age at examination was 35 ± 10 months. Shoulder active ROM (P â ¤ .004) was associated with PSS, whereas passive ROM was not (P â ¥ .08). History of secondary shoulder surgery and primary nerve graft repair were associated with PSS (P = .04). Extent of NBPP by Narakas classification was not associated with PSS (P = .48).ConclusionsEarly use of fullâ arc passive ROM home exercise program is not associated with increased prevalence of PSS in children with NBPP compared to prevalence of PSS in published literature. We suggest careful clinical examination, based on defined criteria, provides a reasonable screening examination for evaluating PSS that can be confirmed by noninvasive US.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147125/1/pmr21235.pd
Examining mental health correlates of hate-motivated behaviour in Scotland : an investigation of victims, perpetrators, and victim-perpetrators
Background: Hate-motivated behaviour (HMB) ranges from microaggressions to criminal acts and is a public health concern with wide-ranging consequences. Aims: The current study aimed to examine the mental health correlates of HMB perpetration, victimisation and co-occurring victimisation/perpetration. Methods: Participants (n=447) completed an online cross-sectional survey assessing demographic factors, HMB (perpetration and victimisation), positive mental wellbeing, and symptoms of depression and anxiety. Results: HMB victimisation was associated with lower positive mental wellbeing and increased symptoms of anxiety and depression. However, neither HMB perpetration nor co-occurring perpetration/victimisation were associated with any of the three mental health outcome measures. Conclusion: Experiencing HMB as a victim is linked to increased psychological distress. Additional research, which focuses on sampling populations who are known to be at greater risk for involvement in HMB, is needed to fully understand the impact of the victim-offender overlap on mental health outcomes

The Associations Between Children's and Adolescents’ Suicidal and Self-Harming Behaviors, and Related Behaviors Within Their Social Networks: A Systematic Review
© 2017, Copyright © International Academy for Suicide Research.Social influences—including the suicidal and self-harming behaviors of others—have been highlighted as a risk factor for suicidal and self-harming behavior in young people, but synthesis of the evidence is lacking. A systematic review of 86 relevant papers was conducted. Considerable published evidence was obtained for positive associations between young people's suicidal and self-harming behavior and that of people they know, with those reporting knowing people who had engaged in suicidal or self-harming behaviors more likely to report engaging in similar behaviors themselves. Findings are discussed in relation to a number of methodological and measurement issues—including the role of normative perceptions—and implications for the prevention of suicidal and self-harming behavior are considered
Older adults' vaccine hesitancy : psychosocial factors associated with influenza, pneumococcal, and shingles vaccine uptake
Influenza, pneumococcal disease, and shingles (herpes zoster) are more prevalent in older people. These illnesses are preventable via vaccination, but uptake is low and decreasing. Little research has focused on understanding the psychosocial reasons behind older adults' hesitancy towards different vaccines. A cross-sectional survey with 372 UK-based adults aged 65-92 years (M = 70.5) assessed awareness and uptake of the influenza, pneumococcal, and shingles vaccines. Participants provided health and socio-demographic data and completed two scales measuring the psychosocial factors associated with vaccination behaviour. Self-reported daily functioning, cognitive difficulties, and social support were also assessed. Participants were additionally given the opportunity to provide free text responses outlining up to three main reasons for their vaccination decisions. We found that considerably more participants had received the influenza vaccine in the last 12 months (83.6%), relative to having ever received the pneumococcal (60.2%) and shingles vaccines (58.9%). Participants were more aware of their eligibility for the influenza vaccine, and were more likely to have been offered it. Multivariate logistic regression analyses showed that a lower sense of collective responsibility independently predicted lack of uptake of all three vaccines. Greater calculation of disease and vaccination risk, and preference for natural immunity, also predicted not getting the influenza vaccine. For both the pneumococcal and shingles vaccines, concerns about profiteering further predicted lack of uptake. Analysis of the qualitative responses highlighted that participants vaccinated to protect their own health and that of others. Our findings suggest that interventions targeted towards older adults would benefit from being vaccine-specific and that they should emphasise disease risks and vaccine benefits for the individual, as well as the benefits of vaccination for the wider community. These findings can help inform intervention development aimed at increasing vaccination uptake in future
Improving older adults' vaccination uptake : are existing measures of vaccine hesitancy valid and reliable for older people?
We sought to establish whether two recently developed measures, the 5C scale and the Vaccination Attitudes Examination (VAX) were reliable and valid for use with older adults. A total of 372 UK-dwelling participants (65–92 years, M = 70.5 years, SD = 4.6) completed a cross-sectional survey measuring health and socio-demographic characteristics in relation to vaccine uptake for influenza, pneumococcal and shingles. The 5C and VAX scales were administered to test their reliability, validity and dimensionality. Both scales showed good internal reliability and convergent, discriminant and concurrent validity. Their factor structures were also confirmed, supporting their use with older adult populations
