The methods for secure outsourcing and secure one-time programs have recently been of great research interest. Garbling schemes are regarded as a promising technique for these applications while Bellare, Hoang and Rogaway introduced the first formal security notions for garbling schemes in [3, 4]. Ever since, even more security notions have been introduced and garbling schemes have been categorized in different security classes according to these notions. In this paper, we introduce new security classes of garbling schemes and build a hierarchy for the security classes including the known classes as well as classes introduced in this paper.
Journal-to-journal citation matrices can be examined with a two-stage double-standardization and hierarchical clustering procedure that has been widely applied to other transaction flow tables. An illustration is given, using 1967–1975 citations between 22 mathematical journals. Groups oriented to analysis and to algebra are discerned. Certain journals, such as theProceedings of the American Mathematical Society, are shown to have broad, nonspecialized tjes with the other periodicals.

Development of research methods requires a systematic review of their status. This study focuses on the use of Hierarchical
Linear Modeling methods in psychiatric research. Evaluation includes 207 documents published until 2007, included and indexed
in the ISI Web of Knowledge databases; analyses focuses on the 194 articles in the sample. Bibliometric methods are used to
describe the publications patterns. Results indicate a growing interest in applying the models and an establishment of methods
after 2000. Both Lotka’s and Bradford’s distributions are adjusted to the data.
Sixty durum wheat genotypes were analysed for protein (gliadin) polymorphism to find out the existing genetic diversity, and to assess its utility for improvement in grain yield along with quality traits. Six different
alleles were found in land races, rust resistance sources and old released varieties, while two in recently released and advance lines. Most of the recently released varieties and advance lines showed γ-45/
alleles, which is the best type for pasta making quality, remaining showed γ-42/
allele, which are not good for pasta making. It is advisable to select for γ-45/
as a bio-chemical marker in the future breeding programmes. The rust resistance sources do not possess γ-45/
alleles, so these lines can be used as donors to introduce disease resistance in the good quality recently released varieties, which are containing γ-45/
alleles. From hierarchical analysis, it was found that landraces, released varieties and rust resistance sources are genetically distinct. The presence of new γ-gliadin patterns are interesting in rust resistance sources and need to be investigated for their role in pasta making as well as overall technological quality of durum wheat.
