The principle ADS asserts that every linear order on ω has an infinite ascending or descending sequence. This has been studied extensively in the reverse mathematics literature, beginning with the work of Hirschfeldt and Shore [16]. We introduce the principle ADC, which asserts that every such linear order has an infinite ascending or descending chain. The two are easily seen to be equivalent o...

We present data on maltreatment profiles and psychopathology of 358 children and adolescents (4-17 years). Data on maltreatment profiles has been categorized into six major maltreatment types: physical abuse, emotional abuse, sexual abuse, sexual abuse with penetration, exposure to intimate partner violence and neglect. The data on history of maltreatment is based on the interview version of th...

The purpose of this study was to determine the frequency of sexual abuse and depression among street children who live in a deprived district of Tehran. The researchers used the K-SADS questionnaire and a clinical interview were used to evaluate depression and sexual abuse in 87 street children in Tehran. Eighteen (20.9%) of the children had been sexually abused. Depressed children were 3.2 tim...

Abstract In the early 2000s, SADS, an extensive linguistic atlas project, surveyed more than three thousand individuals across German-speaking Switzerland on over two hundred variants, capturing morphosyntactic variation in Swiss German. this paper, we applied TESS, a Bayesian clustering method from evolutionary biology to SADS infer population structure, building parallels between and linguist...

The Schedule for Affective Disorders and Schizophrenia (SADS), Part I, and the Present State Examination (PSE) are both structured interviews to assess the present psychiatric condition. The present article attempts to provide researchers with information that may help them to decide which of the two instruments would be most suitable for their purposes. We describe the similarities and differe...

Species abundance distributions (SADs) describe community structure and are a key component of biodiversity theory research. Although different have been proposed to represent SADs at scales, systematic empirical assessment how SAD shape varies across wide scale gradients is lacking. Here, we examined 11 large-scale datasets for range taxa used maximum likelihood methods compare the fit logseri...

BACKGROUND This study tested the hypothesis that risk behaviours in disadvantaged groups would explain socio-economic inequality in dental caries prevalence among preschool children. METHODS Using a case-control study, children with caries experience (one or more decayed, missing or filled primary tooth surfaces) and with no caries experience were sampled with known probabilities from among f...

Senescent cells have a case of the SADS C ells unravel their centro-meres as they enter senes-cence, Swanson et al. reveal. Senescent cells are metabolically active but no longer capable of dividing. This permanent exit from the cell cycle can be induced by the telomere shortening associated with aging or by other stresses such as the expression of active onco-genes. Despite the importance of s...
