We have previously proposed BB94] a model for the generation of segmental durations which proceeds in two steps : (a) prediction of the timing of a salient acoustic event per syllable according to phonotactic and syntactic information, and (b) application of a repartition model which determines the duration of each individual segment between these events. This paper focusses on the repartition ...
1.1 Z-scores versus one-sample T-tests If we knew the mean, µ , and standard deviation, σ , of the control "population", we could construct the "Z-score": σ µ p Z − = where p is the single patient score, and determine the probability of obtaining a Z-score this large from the "Z-distribution" (or "normal" or "Gaussian" distribution). In practice, Z-scores are often tested this way when the grou...
Background: The primary objective of this study was to assess BMD change in Iranian females with breast cancer. Methods: A sample of 73 female breast cancer patients treated with adjuvant chemotherapy either alone or followed by radiotherapy between March 2013 and February 2016 were considered for this study. Bone mineral density (BMD) change was evaluated by measuring z-score of lumbar spin...
BACKGROUND Perfluoroalkyl substances (PFAS) may affect body mass index (BMI) and other components of cardiometabolic (CM) risk during childhood, but evidence is scarce and inconsistent. OBJECTIVES We estimated associations between prenatal PFAS exposures and outcomes relevant to cardiometabolic risk, including a composite CM-risk score. METHODS We measured perfluorohexanesulfonic acid (PFHx...
OBJECTIVE Genome-wide linkage analyses of schizophrenia have identified several regions that may harbor schizophrenia susceptibility genes, but given the complex etiology of the disorder, it is unlikely that all susceptibility regions have been detected. To address this issue, the authors ascertained 606 Han Chinese families comprising 1,234 affected members. METHOD Probands with schizophreni...
OBJECTIVE To examine the effectiveness of home visiting by paraprofessionals and by nurses as separate means of improving maternal and child health when both types of visitors are trained in a program model that has demonstrated effectiveness when delivered by nurses. METHODS A randomized, controlled trial was conducted in public- and private-care settings in Denver, Colorado. One thousand on...
BACKGROUND Evidence suggests that changes in family income are an important determinant of children's body mass index (BMI). However, few studies have leveraged longitudinal data to investigate the association of changes in family income on changes in BMI z score. OBJECTIVE This study aimed to assess whether gains in family income are associated with changes in BMI z score among children in t...
OBJECTIVE To evaluate a healthy lifestyle intervention to reduce adiposity in children aged 5 to 9 years and assess whether adding parenting skills training would enhance this effect. PARTICIPANTS AND METHODS We conducted a single-blinded randomized controlled trial of prepubertal moderately obese (International Obesity Task Force cut points) children, aged 5 to 9 years. The 6-month program t...
Background/Objectives. This pilot study evaluated the impact of a peer support program on improving multiple sclerosis (MS) related psychological functions (depression, anxiety, and stress) and enhancing quality of life. Methodology. Participants (n = 33) were recruited prospectively and received an 8-week group face-to-face peer support program. Assessments were at baseline (T1), 6 weeks after...
