FIXED‐RATIO PERFORMANCE WITH AND WITHOUT A POSTREINFORCEMENT TIMEOUT [PDF]

Journal of the Experimental Analysis of Behavior, 1982
Pigeons pecked a key, producing food reinforcement on fixed‐ratio (FR) schedules requiring 50, 100, or 150 responses. In each session, 30‐second timeouts were inserted before a random half of the FR trials, whereas the other trials began immediately after reinforcement. In general, preratio pauses were shorter on trials preceded by timeouts.

Understanding Anti-performance: The performative division of experience and the standpoint of the non-performer [PDF]

, 2020
Performance theorists have long been drawn to the potential of performance to subvert established institutions. The results of performance are never fully determined in advance; performances subject established images to reinterpretation; they take place

The Impact of the COVID‐19 Pandemic on Childhood Cancer Survival: A Population‐Based Assessment of Survival Patterns Between 2015 and 2023 in Germany

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Numerous international studies have reported declines in new cancer diagnoses, delayed diagnoses and disruptions in cancer treatment following the implementation of COVID‐19 pandemic public health measures, raising concerns that these effects may ultimately contribute to increased cancer mortality.

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Efficiency of speed and agilty dribbling of young basketball players

Kinesiologia Slovenica, 2017
In the study we have measured and analyzed dribbling efficiency i.e. performance ratio (PR) of young basketball players. For this purpose five speed and agility tests (with and without the ball) were aplied on the group of 65 participants from two age ...

Weather-Corrected Performance Ratio [PDF]

, 2013
Photovoltaic (PV) system performance depends on both the quality of the system and the weather. One simple way to communicate the system performance is to use the performance ratio (PR): the ratio of the electricity generated to the electricity that would have been generated if the plant consistently converted sunlight to electricity at the level ...

Bone Mineral Density After Contemporary Treatment for Acute Lymphoblastic Leukaemia: A Matched Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Reduced bone mineral density (BMD) has been reported in survivors of childhood and young adult acute lymphoblastic leukaemia (ALL); however, data from cohorts treated with contemporary protocols and including matched controls remain limited.

Experimental analysis of wavelet decomposition on edge detection; pp. 284–298 [PDF]

Proceedings of the Estonian Academy of Sciences, 2019
The influence of different wavelet transformations and decomposition on edge detection was examined, using convenient operators to images of various complexities. Berkeley Segmentation Database images with the corresponding ground truth were used.

Robust performance hypothesis testing with the Sharpe ratio [PDF]

Journal of Empirical Finance, 2008
Applied researchers often test for the difference of the Sharpe ratios of two investmentnstrategies. A very popular tool to this end is the test of Jobson and Korkie (1981), whichnhas been corrected by Memmel (2003). Unfortunately, this test is not valid when returnsnhave tails heavier than the normal distribution or are of time series nature. Instead,
