Measuring deviant sexual interest in Adolescents using the emotional Stroop task.

Adolescent sexual abusers are a heterogeneous group of offenders that often receive generic assessment and treatment services that are modeled on research findings from adult sex offender samples. The emotional Stroop task has been used to measure deviant sexual interest in adult samples. The purpose of the present study was to test whether the emotional Stroop task could also be used to assess deviant sexual interest in adolescent samples. Three groups of adolescents (a) sexual abusers (n = 24); (b) offending controls (n = 21); and (c) nonoffending controls (n = 21) completed two emotional Stroop tasks related to deviant sexual interest and tests of executive function. Adolescent sexual abusers were significantly slower to color-name some word stimuli than both adolescent offending controls and adolescent nonoffending controls. However, the task was unable to differentiate between the groups on most of the Stroop word categories. Very little research has been conducted with adolescent offender samples and the emotional Stroop task. Reaction time (RT) and Stroop bias outcome data for adolescent samples appear to be more unsystematic and weaker than has been observed in previous adult data. Based on potential difficulties with reading and development, the emotional Stroop task may not be a task suitable for measuring deviant sexual interest in adolescent samples

Human mummification practices among the Ibaloy of Kabayan, North Luzon, the Philippines

The province of Benguet, situated in North Luzon, the Philippines, holds a large number of ancient mummified remains, mostly located within the municipality of Kabayan. Such bodies are mainly associated to the Ibaloy – one of the indigenous groups collectively known as Igorot – and are stored in natural rockshelters or caves carved into the stone, inside wooden coffins often obtained from hollowed pine tree segments. Recent inspections of some of these corpses, carried out in 2002 and 2012, indicated the nature of their mummification process as well as some details regarding their bioanthropological features. Although very little information was initially available on these bodies, the authors have gathered significant oral information on funerary rituals and attitudes towards the ancestors via interviews with the local elders, as well as data on the vegetal materials employed and the practice of tattooing. This paper is the first critical evaluation of these mummies and demonstrates the uniqueness and preciousness of this biocultural heritage now in danger

Longitudinal development of initial, chronic and mucoid Pseudomonas aeruginosa infection in young children with cystic fibrosis

BACKGROUND: While the emergence of chronic and mucoid Pseudomonas aeruginosa (Pa) infection are both associated with poorer outcomes among CF patients, their relationship is poorly understood. We examined the longitudinal relationship of incident, chronic and mucoid Pa in a contemporary, young CF cohort in the current era of Pa eradication therapy. METHODS: This retrospective cohort was comprised of patients in the U.S. CF Foundation Patient Registry born 2006-2015, diagnosed before age 2, and with at least 3 respiratory cultures annually. Incidence and age-specific prevalence of Pa infection stages (initial and chronic [≥ 3Pa+cultures in prior year]) and of mucoid Pa were summarized. Transition times and the interaction between Pa stage and acquisition of mucoid Pa were examined via Cox models. RESULTS: Among the 5592 CF patients in the cohort followed to a mean age of 5.5years, 64% (n=3580) acquired Pa. Of those, 13% (n=455) developed chronic Pa and 17% (n=594) cultured mucoid Pa. Among those with mucoid Pa, 36% (211/594) had it on their first recorded Pa+culture, while mucoid Pa emerged at or after entering the chronic stage in 12% (73/594). Mucoidy was associated with significantly increased risk of transition to chronic Pa infection (HR=2.59, 95% CI 2.11, 3.19). CONCLUSIONS: Two-thirds of early-diagnosed young children with CF acquired Pa during a median 5.6years of follow up, among whom 13% developed chronic Pa and 17% acquired mucoid Pa. Contrary to our hypothesis, 87% of young children who developed mucoid Pa did so before becoming chronically infected

Ahrensite, γ-Fe_2SiO_4, a new shock-metamorphic mineral from the Tissint meteorite: Implications for the Tissint shock event on Mars

Ahrensite (IMA 2013-028), γ-Fe_2SiO_4, is the natural Fe-analog of the silicate-spinel ringwoodite (γ-Mg_2SiO_4). It occurs in the Tissint Martian meteorite, where it forms through the transformation of the fayalite-rich rims of olivine megacrysts or Fe-rich microphenocrysts in contact with shock melt pockets. The typical sequence of phase assemblages traversing across a Tissint melt pocket into olivine is: quenched melt or fayalite-pigeonite intergrowth ⇒ bridgmanite + wüstite ⇒ ahrensite and/or ringwoodite ⇒ highly-deformed olivine + nanocrystalline ringwoodite ⇒ deformed olivine. We report the first comprehensive set of crystallographic, spectroscopic, and quantitative chemical analysis of type ahrensite, and show that concentrations of ferric iron and inversion in the type material of this newly approved mineral are negligible. We also report the occurrence of nanocrystalline ringwoodite in strained olivine and establish correlations between grain size and distance from melt pockets. The ahrensite and ringwoodite crystals show no preferred orientation, consistent with random nucleation and incoherent growth within a highly strained matrix of olivine. Grain sizes of ahrensite immediately adjacent to melt pockets are consistent with growth during a shock of moderate duration (1–10 ms)

Tissintite, (Ca,Na,□)AlSi_2O_6: A Shock-Induced Clinopyroxene in the Tissint Meteorite

During a nanomineralogy investigation of the Tissint Martian meteorite, we discovered the new shock-induced mineral tissintite, (Ca,Na,□)AlSi_2O_6, which is named after Tissint, Morocco, where the host meteorite fell. This phase provides new insights into shock conditions and impact processes on Mars. Here, we emphasize the origin of tissintite (IMA 2013-027) and demonstrate how nanomineralogy can play an important role in meteorite and Mars rock research
