Palliative Care in residential care facilities: a brief review

The article by Kristjanson, Walton and Toye in this issue describes the Western Australian context of caring for older people dying in residential care. This response will very briefly draw on some of the work done in this area in the UK, Australia and the US. In the past few years several edited collections have provided extensive information about both the dearth of research as well as ongoing research in this area (e.g. Hockley and Clark, 2002; Katz and Peace, 2003; Morrision and Meier, 2003)

Adaptation of Dopamine Neurons' Mismatch Sensitivity Is not Compatible With Reinforcement Learning Theory

Recent electrophysical data inspired the claim that dopaminergic neurons adapt their mismatch sensitivities to reflect variances of expected rewards. This contradicts reward prediction error theory and most basal ganglia models. Application of learning principles points to a testable alternative interpretation-of the same data-that is compatible with existing theory.National Science Foundation (SBE-354378); Higher Education Council of Turkey; Canakkale Onsekiz Mart University of Turke

A review of described Metacyrba, the status of Parkella, and notes on Platycryptus and Balmaceda : with a comparison of the genera (Araneae: Salticidae: Marpissinae)

Parkella Chickering 1946 = Metacyrba F. O. P.-Cambridge 1901, n. syn.; Parkella venusta Chickering 1946 = Metacyrba venusta (Chickering 1946), n. comb.; Parkella fusca Chickering 1946 and Dendryphantes franganilloi Caporiacco 1955 = Metacyrba venusta (Chickering 1946), n. syn. The six valid described species of Metacyrba are diagnosed and re-illustrated to show previously unrecognized genitalic differences. Metacyrba similis Banks 1904 is resurrected as a subspecies, becoming Metacyrba taeniola similis Banks 1904, n. status. The female of Metacyrba pictipes Banks 1903 is described for the first time. Metacyrba arizonensis Barnes 1958 = Platycryptus arizonensis (Barnes 1958), n. comb., and Marpissa magna (Peckham & Peckham 1894) = Platycryptus magnus (Peckham & Peckham 1894), n. comb. Platycryptus broadwayi (Peckham & Peckham 1894) = Platycryptus magnus (Peckham & Peckham 1894), n. syn. [lectotypes and paralectotypes are designated for both names]. Metacyrba nigrosecta (Mello-Leitão 1945) = Balmaceda nigrosecta Mello-Leitão 1945, comb. restored. The genera Balmaceda Peckham & Peckham 1894, Metacyrba, and Platycryptus Hill 1979 are compared morphologically among themselves and to Breda Peckham & Peckham 1894 and Fuentes Peckham & Peckham 1894. The distributions of Balmaceda picta Peckham & Peckham 1894 and Metacyrba species are updated. Marpissa melanura F.O.P.-Cambridge 1901 is resurrected; it is not a synonym of Marpissa minor F.O.P.-Cambridge 1901 nor Platycryptus californicus (Peckham & Peckham 1888)

Characterization of mesostasis areas in mare basalts: constraining melt compositions from which apatite crystallizes

Crystallization of major silicate and oxide phases from basaltic melts produces late-stage liquids whose chemical compositions differ from the initial melt. These chemically evolved liquids crystallize phases in the interstitial mesostasis regions in lunar basaltic rocks. Enrichment of incompatible elements, including volatiles such as OH, F, Cl, is characteristic of these late-stage liquids and encourages growth of accessory phases including apatite [Ca5(PO4)2(F,Cl,OH)]. Apatite is the main volatile bearing crystalline phase in lunar rocks. It starts crystallizing after ~95% melt solidification in typical mare basalts, but could crystallize earlier, after ~85-90% solidification in KREEP basalts. Using the OH contents of apatites, several researchers have calculated water contents for parental magmas. These calculated parental magma water contents can then be used to estimate a range of values for water in the mantle source regions of mare basalts [e.g.,2-6]. Therefore, a better characterization of the mesostasis areas, and of the melts in which apatite forms, is paramount to gain further insights and constraints on water in the lunar interior, especially because important parameters such as partitioning of volatiles between late-stage melts and apatite remain poorly constrained

Ukrainian Students in Spain after World War II

The paper analyzes a book written by Volodymyr Yarymovych, Oleksandr Bilyk, and Mykola Volynskyi, entitled Narys istorii ukrainskoi studentskoi hromady ta Ukrainskykh poselen v Espanii 1946–1996 (An Overview of the History of the Ukrainian Student Community and Ukrainian Settlements in Spain, 1946–1996), which tells about the Ukrainian students who arrived in Madrid in 1946 and formed part of the early Ukrainian Diaspora in Spain. The book proves to be an important source of information, previously unknown to scholars, which describes the dramatic and controversial process of constructing Ukrainian identity in the aftermath of World War II. The authors of the study consider the historical and cultural context of the Ukrainian emigration in the second half of the 20th century, its connection with Francoist ideology, and its integral role in the Spanish-Ukrainian cultural dialogue
