The current study replicated an enhanced stimulus-stimulus pairing (SSP) procedure used by Esch et al. (Journal of Applied Behavior Analysis 42: 42-225, 2009) for increasing vocalizations in children with autism. The enhanced SSP procedure consisted of pairing target vocalizations with high-preference items, interspersed target and nontarget trials, an observing response, and the presentation o...

Stellar population parameters (e.g. age, metallicity, and stellar abundance ratios) derived from spectral line-strengths provide a powerful probe of galaxy properties and formation histories. We implement the machinery for extracting line-strengths and ‘single-stellar-populationequivalent’ (SSP-equivalent) stellar population parameters from synthetic spectra generated by a hierarchical galaxy f...

This article is a retrospective of concepts and people who have contributed significantly to the IEEE Symposium on Security and Privacy over the past 30 years. • We identify many individuals who have contributed to SSP as program chairs, general chairs, and heads of the overseeing IEEE technical committee. • We recognize SSP participants who have provided significant leadership in creating and ...

The subset-sum problem (SSP) is deened as follows: given a positive integer bound and a set of n positive integers nd a subset whose sum is closest to, but not greater than, the bound. We present a randomized approximation algorithm for this problem with linear space complexity and time complexity of O(n log n). Experiments with random uniformly-distributed instances of SSP show that our algori...

This study's primary goal was to examine relations between symptoms of specific social phobia (SSP), generalized social phobia (GSP), avoidant personality disorder (APD), and panic and depression. Past research has suggested a single social phobia continuum in which SSP displays less symptom severity than GSP or APD. We found SSP symptoms correlated less strongly with depression but more strong...

A key finding of the Reliable Information Access Workshop of 2003 was that in collections like those used for TREC 6-8, there are a number of hard queries for which no current search engine can return a high quality set of results. Our Stepping Stones and Pathways (SSP) approach may yield an effective solution to such hard problems, as well as support exploration of collections of content not w...

background: in current study, chemical composition and antibacterial activity of leaves and flowers essential oils of origanum vulgare ssp. gracile against four food-borne pathogens including  escherichia coli, listeria monocytogenes, salmonella thyphimurium and staphylococcus aureus were examined. methods: the different organs (leaves and flowers) of o. vulgare ssp. gracile were harvested at f...

We applied a polymerase chain reaction-sequence specific primer (PCR-SSP) method developed by other researchers to study 4 families of newborns with neonatal alloimmune thrombocytopenia (NAITP) in which serology had provided inconclusive human platelet antigen (HPA) typing data. This method allowed for the identification of the newborn HPAs which were incompatible with their respective mothers....

A dosage effect of chromosome 5A (formerly IX) of common wheat, Triticum aestivum L. emend Thell. ssp. vulgare, has been well established. With increasing dosage from monosomic to tetrasomic, the phenotype changes from speltoid to normal vulgare type (squarehead) to subcompactoid to compactoid (HUSKINS 1946; SEARS 1952, 1954) (Figure 1 and Table 3) . This is due to the pleiotropic gene Q locate...
