3 theoretical approaches to the origin and development o f the infant-mother relationship are reviewed: psychoanalytic theories of object relations, social learning theories of dependency (and attachment), and an ethologically oriented theory o f attachment. "Object relations," "dependency," and "attachment," although overlapping, are seen to differ substantially. Among the concepts in regard t...

THE TITLE COMPOUND [SYSTEMATIC NAME: (3S,3aS,10bR)-3-isopropyl-5a,8-dimethyl-2,3,4,5,5a,6,7,10,10a,10b-deca-hydro-endo-epidioxy-cyclo-hepta-[e]indene-3a(1H)-carboxylic acid], C(20)H(30)O(4), is a polymorphic form of a previously reported structure [Loyola et al. (1990 ▶). Tetra-hedron, 46, 5413-5420]. The newly found ortho-rhom-bic polymorph crystallizes in P2(1)2(1)2(1) with two mol-ecules in ...

Structured peer-to-peer hash tables provide decentralization, self-organization, failure-resilience, and good worst-case lookup performance for applications, but suffer from high latencies (O( )) in the average case. Such high latencies prohibit them from being used in many relevant, demanding applications such as DNS. In this paper, we present a proactive replication framework that can achieve...

Caudal neurosecretory system is an additional neuroendocrine system found in fishes. Great variation has been observed among different groups of fishes, so far its organization is concerned. Much work has been undertaken on the caudal neurosecretory system of elasmobranchs and teleosts. large size scattered Dahlgren cells in the posterior end of spinal cord, corresponding to last few vertebrae,...

Top-down and centralized approaches prevail in the design and improvement of business processes. However, centralized structures pose difficulties for organizations in adapting to a rapidly changing business environment. Here we present the Plural method which can be used to guide organizations in performing process modeling in a decentralized way. Instead of a centralized group of people under...
