TL;DR: The PSA failure rates (hazard ratios) were similar for the index tumor and the index plus smaller cancers, confirming that predictive estimates only need to measure the largest carcinoma.

TL;DR: This study demonstrates that traumatic exposure, PTSD symptoms, and other factors are associated with attitudes toward justice and reconciliation and should be considered if reconciliation is to be realized.
Abstract: ContextThe 1994 genocide in Rwanda led to the loss of at least 10% of the country's
7.7 million inhabitants, the destruction of much of the country's infrastructure,
and the displacement of nearly 4 million people. In seeking to rebuild societies
such as Rwanda, it is important to understand how traumatic experience may
shape the ability of individuals and groups to respond to judicial and other
reconciliation initiatives.ObjectivesTo assess the level of trauma exposure and the prevalence of posttraumatic
stress disorder (PTSD) symptoms and their predictors among Rwandans and to
determine how trauma exposure and PTSD symptoms are associated with Rwandans'
attitudes toward justice and reconciliation.Design, Setting, and ParticipantsMultistage, stratified cluster random survey of 2091 eligible adults
in selected households in 4 communes in Rwanda in February 2002.Main Outcome MeasuresRates of exposure to trauma and symptom criteria for PTSD using the
PTSD Checklist–Civilian Version; attitudes toward judicial responses
(Rwandan national and gacaca local trials and International Criminal Tribunal
for Rwanda [ICTR]) and reconciliation (belief in community, nonviolence, social
justice, and interdependence with other ethnic groups).ResultsOf 2074 respondents with data on exposure to trauma, 1563 (75.4%) were
forced to flee their homes, 1526 (73.0%) had a close member of their family
killed, and 1472 (70.9%) had property destroyed or lost. Among the 2091 total
participants, 518 (24.8%) met symptom criteria for PTSD. The adjusted odds
ratio (OR) of meeting PTSD symptom criteria for each additional traumatic
event was 1.43 (95% CI, 1.33-1.55). More respondents supported the local judicial
responses (90.8% supported gacaca trials and 67.8% the Rwanda national trials)
than the ICTR (42.1% in support). Respondents who met PTSD symptom criteria
were less likely to have positive attitudes toward the Rwandan national trials
(OR, 0.77; 95% CI, 0.61-0.98), belief in community (OR, 0.76; 95% CI, 0.60-0.97),
and interdependence with other ethnic groups (OR, 0.71; 95% CI, 0.56-0.90).
Respondents with exposure to multiple trauma events were more likely to have
positive attitudes toward the ICTR (OR, 1.10; 95% CI, 1.04-1.17) and less
likely to support the Rwandan national trials (OR, 0.90; 95% CI, 0.84-0.96),
the local gacaca trials (OR, 0.80; 95% CI, 0.72-0.89), and 3 factors of openness
to reconciliation: belief in nonviolence (OR, 0.92; 95% CI, 0.87-0.97), belief
in community (OR, 0.92; 95% CI, 0.87-0.98), and interdependence with other
ethnic groups (OR, 0.86; 95% CI, 0.81-0.92). Other variables that were associated
with attitudes toward judicial processes and openness to reconciliation were
educational level, ethnicity, perception of change in poverty level and access
to security compared with 1994, and ethnic distance.ConclusionsThis study demonstrates that traumatic exposure, PTSD symptoms, and
other factors are associated with attitudes toward justice and reconciliation.
Societal interventions following mass violence should consider the effects
of trauma if reconciliation is to be realized.

TL;DR: In this paper, a three-phase shunt active filter (AF) is used to regulate load terminal voltage, eliminate harmonics, correct supply power-factor, and balance the nonlinear unbalanced loads.
Abstract: This paper deals with an implementation of a new control algorithm for a three-phase shunt active filter to regulate load terminal voltage, eliminate harmonics, correct supply power-factor, and balance the nonlinear unbalanced loads. A three-phase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter (CC-VSI) with a DC bus capacitor is used as an active filter (AF). The control algorithm of the AF uses two closed loop PI controllers. The DC bus voltage of the AF and three-phase supply voltages are used as feedback signals in the PI controllers. The control algorithm of the AF provides three-phase reference supply currents. A carrier wave pulse width modulation (PWM) current controller is employed over the reference and sensed supply currents to generate gating pulses of IGBTs of the AF. Test results are presented and discussed to demonstrate the voltage regulation, harmonic elimination, power-factor correction and load balancing capabilities of the AF system.

29 Sep 2014TL;DR: In this paper, the equality of two population correlation coefficients when the data are bivariate normal and Pearson correlation coefficients are used as estimates of the population parameters is a straightforward procedure covered in many introductory statistics courses.
Abstract: Testing the equality of two population correlation coefficients when the data are bivariate normal and Pearson correlation coefficients are used as estimates of the population parameters is a straightforward procedure covered in many introductory statistics courses. The coefficients are converted using Fisher's z-transformation with standard errors (N − 3)−1/2. The two transformed values are then compared using a standard normal procedure. When data are not bivariate normal, Spearman's correlation coefficient rho is often used as the index of correlation. Comparison of two Spearman rhos is not as well documented. Three approaches were investigated using Monte Carlo simulations. Treating the Spearman coefficients as though they were Pearson coefficients and using the standard Fisher's z-transformation and subsequent comparison was more robust with respect to Type I error than either ignoring the nonnormality and computing Pearson coefficients or converting the Spearman coefficients to Pearson equivalents prior to transformation.
