Acceptance and Commitment Therapy

Abstract: ACT is an example of a third wave behavior therapy that saves direct change strategies for overt behaviors and utilizes contextual and experiential methods such as mindfulness and acceptance to address cognitive process that hinder and limit overt behavioral change. The treatment is informed by RFT and is based on the philosophical position of functional contextualism. ACT seeks to undermine the literal grip of language (relational framing) that fosters experiential avoidance, cognitive fusion, and behavioral inflexibility, through the application of six core psychological techniques: acceptance, defusion, contact with the present moment, self-as as-context, values, and commitment to behavior change. Homework can play an integral role in the application of these techniques, by supporting the in-session therapy. Homework can be especially useful because it allows the client to utilize these principles in situations that cannot be created in the therapy sessions, such as public situation for someone who struggles with anxiety. As with most therapies, ACT has its own homework assignments, but therapists often create new techniques to serve the clients needs.

Simple sequence repeat map of the sunflower genome

Abstract: Several independent molecular genetic linkage maps of varying density and completeness have been constructed for cultivated sunflower ( Helianthus annuus L.). Because of the dearth of sequence and probe-specific DNA markers in the public domain, the various genetic maps of sunflower have not been integrated and a single reference map has not emerged. Moreover, comparisons between maps have been confounded by multiple linkage group nomenclatures and the lack of common DNA markers. The goal of the present research was to construct a dense molecular genetic linkage map for sunflower using simple sequence repeat (SSR) markers. First, 879 SSR markers were developed by identifying 1,093 unique SSR sequences in the DNA sequences of 2,033 clones isolated from genomic DNA libraries enriched for (AC)(n) or (AG)(n) and screening 1,000 SSR primer pairs; 579 of the newly developed SSR markers (65.9% of the total) were polymorphic among four elite inbred lines (RHA280, RHA801, PHA and PHB). The genetic map was constructed using 94 RHA280 x RHA801 F(7) recombinant inbred lines (RILs) and 408 polymorphic SSR markers (462 SSR marker loci segregated in the mapping population). Of the latter, 459 coalesced into 17 linkage groups presumably corresponding to the 17 chromosomes in the haploid sunflower genome ( x = 17). The map was 1,368.3-cM long and had a mean density of 3.1 cM per locus. The SSR markers described herein supply a critical mass of DNA markers for constructing genetic maps of sunflower and create the basis for unifying and cross-referencing the multitude of genetic maps developed for wild and cultivated sunflowers.

Clustering Analysis of Seismicity and Aftershock Identification

Abstract: We introduce a statistical methodology for clustering analysis of seismicity in the time-space-energy domain and use it to establish the existence of two statistically distinct populations of earthquakes: clustered and nonclustered. This result can be used, in particular, for nonparametric aftershock identification. The proposed approach expands the analysis of Baiesi and Paczuski [Phys. Rev. E 69, 066106 (2004)10.1103/PhysRevE.69.066106] based on the space-time-magnitude nearest-neighbor distance eta between earthquakes. We show that for a homogeneous Poisson marked point field with exponential marks, the distance eta has the Weibull distribution, which bridges our results with classical correlation analysis for point fields. The joint 2D distribution of spatial and temporal components of eta is used to identify the clustered part of a point field. The proposed technique is applied to several seismicity models and to the observed seismicity of southern California.

A Block-Cipher Mode of Operation for Parallelizable Message Authentication

Abstract: We define and analyze a simple and fully parallelizable blockcipher mode of operation for message authentication. Parallelizability does not come at the expense of serial efficiency: in a conventional, serial environment, the algorithm's speed is within a few percent of the (inherently sequential) CBC MAC. The new mode, PMAC, is deterministic, resembles a standard mode of operation (and not a Carter-Wegman MAC), works for strings of any bit length, employs a single block-cipher key, and uses just max{1, ?|M|/n?} block-cipher calls to MAC a string M ? {0, 1}* using an n-bit block cipher. We prove PMAC secure, quantifying an adversary's forgery probability in terms of the quality of the block cipher as a pseudorandom permutation.
