The psychological symptoms of conjugal bereavement in elderly men over the first 13 months

Objective. The purpose of this study was to investigate the psychological symptoms experienced by recently widowed older men. It was hypothesized that conjugal bereavement in this group would be characterized by a mixture of depression, anxiety and loneliness. Design. Double cohort study. Setting. Suburban community population of Brisbane, Australia. Participants. Consecutive widowers (65+ years; N = 57) identified from official death records. Married men (65+ years; N = 57) identified from the electoral roll. Widowers interviewed at 6 weeks, 6 months and 13 months post-bereavement. Married men interviewed at similar intervals. Measures. Bereavement Phenomenology Questionnaire (BPQ), a 22-item self-report measure employing a four-point response scale to rate the frequency of phenomena over the previous fortnight. Zung Self-rating Depression Scale (SDS). State component of the Spielberger State/Trait Anxiety Inventory (STAI). Revised UCLA Loneliness Scale (ULS). 28-item General Health Questionnaire (GHQ). Results. Widowers reported more state anxiety and general psychological distress, but not more depression or loneliness, than matched married men over the first 13 months post-bereavement. Widowers also reported more sleep disturbance and thoughts of death and suicide than married men. Level of state anxiety was strongly correlated with intensity of grief, but not with age, income, education, occupational prestige, cognitive function, duration of wife's final illness or expectedness of wife's death. Conclusions. The main hypothesis was not supported, as anxiety symptoms were the predominant clinical feature of recent conjugal bereavement among older men. The nature of these anxiety symptoms requires further investigation in recently widowed older persons.

Service quality and consumers' experience: Towards an interpretive approach

As marketers and researchers we understand quality from the consumer's perspective, and throughout contemporary service quality literature there is an emphasis on what the consumer is looking for, or at least that is the intention. Through examining the underlying assumptions of dominant service quality theories, an implicit dualistic ontology is highlighted (where subject and object are considered independent) and argued to effectively negate the said necessary consumer orientation. This fundamental assumption is discussed, as are the implications, following a critical review of dominant service quality models. Consequently, we propose an alternative approach to service quality research that aims towards a more genuine understanding of the consumer's perspective on quality experienced within a service context. Essentially, contemporary service quality research is suggested to be limited in its inherent third-person perspective and the interpretive, specifically phenomenographic, approach put forward here is suggested as a means of achieving a first-person perspective on service quality.

QCD thermal phase transition in the presence of a small chemical potential

We propose a new method to investigate the thermal properties of QCD with a small quark chemical potential mu. Derivatives of quark and gluonic observables with respect to mu are computed at mu=0 for two flavors of p4 improved staggered fermions with ma=0.1,0.2 on a 16(3)x4 lattice, and used to calculate the leading order Taylor expansion in mu of the location of the pseudocritical point about mu=0. This expansion should be well behaved for the small values of mu(q)/T(c)similar to0.1 relevant for BNL RHIC phenomenology, and predicts a critical curve T-c(mu) in reasonable agreement with estimates obtained using exact reweighting. In addition, we contrast the case of isoscalar and isovector chemical potentials, quantify the effect of munot equal0 on the equation of state, and comment on the complex phase of the fermion determinant in QCD with munot equal0.

The distribution and morphological characteristics of catecholaminergic cells in the brain of monotremes as revealed by tyrosine hydroxylase immunohistochemistry

The present study describes the distribution and cellular morphology of catecholaminergic neurons in the CNS of two species of monotreme, the platypus (Ornithorhynchus anatinus) and the short-beaked echidna (Tachyglossus aculeatus). Tyrosine hydroxylase immunohistochemistry was used to visualize these neurons. The standard A1-A17, C1-C3 nomenclature was used for expediency, but the neuroanatomical names of the various nuclei have also been given. Monotremes exhibit catecholaminergic neurons in the diencephalon (All, A12, A13, A14, A15), midbrain (A8, A9, A10), rostral rhombencephalon (A5, A6, A7), and medulla (A1, A2, C1, C2). The subdivisions of these neurons are in general agreement with those of other mammals, and indeed other amniotes. Apart from minor differences, those being a lack of A4, A3, and C3 groups, the catecholaminergic system of monotremes is very similar to that of other mammals. Catecholaminergic neurons outside these nuclei, such as those reported for other mammals, were not numerous with occasional cells observed in the striatum. It seems unlikely that differences in the sleep phenomenology of monotremes, as compared to other mammals, can be explained by these differences. The similarity of this system across mammalian and amniote species underlines the evolutionary conservatism of the catecholaminergic system. Copyright (C) 2002 S. Karger AG, Basel.

The distribution and morphological characteristics of cholinergic cells in the brain of monotremes as revealed by ChAT immunohistochemistry

The present study employs choline acetyltransferase (ChAT) immunohistochemistry to identify the cholinergic neuronal population in the central nervous system of the monotremes. Two of the three extant species of monotreme were studied: the platypus (Omithorhynchus anatinus) and the short-beaked echidna (Tachyglossus aculeatus). The distribution of cholinergic cells in the brain of these two species was virtually identical. Distinct groups of cholinergic cells were observed in the striatum, basal forebrain, habenula, pontomesencephalon, cranial nerve motor nuclei, and spinal cord. In contrast to other tetrapods studied with this technique, we failed to find evidence for cholinergic cells in the hypothalamus, the parabigeminal nucleus (or nucleus isthmus), or the cerebral cortex. The lack of hypothalamic cholinergic neurons creates a hiatus in the continuous antero-posterior aggregation of cholinergic neurons seen in other tetrapods. This hiatus might be functionally related to the phenomenology of monotreme sleep and to the ontogeny of sleep in mammals, as juvenile placental mammals exhibit a similar combination of sleep elements to that found in adult monotremes.

Response to Orr and Siegler - collective intentionality and procreative desires: the permissible view on consent to posthumous conception

Orr and Siegler have recently defended a restrictive view concerning posthumous sperm retrieval and conception, which would limit insemination to those cases where the deceased man has provided explicit consent for such a procedure. The restrictive view dominates current law and practice. A permissible view, in contrast, would allow insemination and conception in all but those cases where the posthumous procedure has been explicitly refused, or where there is no reasonable evidence that the deceased person desired children. I describe a phenomenology of procreative desires which supports the permissible view, and which is compatible with requirements concerning the interests of the decedent, concepts of medical infertility, and the welfare of the future child. The account illustrates how our current obsession with individual rights and autonomy can be self-defeating and repressive.

Striving for a common language: A white feminist parallel to Indigenous ways of knowing and researching

In Striving Towards a Common Language I outline an innovative methodology which consists of three strands encompassing an Indigenous-centred approach based on Indigenous Self-determination (participatory action research), relationship as central to socio-cultural dynamics, and feminist phenomenology. This methodology - which I call Living On the Ground was created in direct concert with 13 Indigenous women elders who were my hosts, teachers and walytja (family) as we worked together to create a dynamic cultural revitalisation project for their community, one of Australia's most remote Aboriginal settlements. I explain the processes I went through as a White Irish-Australian woman living with the women elders and their 11 dogs in a one room tin shed for two years, and tell of how the nexus of land, Ancestors, and the Tjukurrpa (Dreaming) combined with White cultural practices came to inspire a methodology which took the best from Indigenous and (White) feminist ways of knowing and of being.

Strong electronic correlations in superconducting organic charge transfer salts

We review the role of strong electronic correlations in quasi-two-dimensional organic charge transfer salts such as (BEDT-TTF)(2)X, (BETS)(2)Y, and beta'-[Pd(dmit)(2)](2)Z. We begin by defining minimal models for these materials. It is necessary to identify two classes of material: the first class is strongly dimerized and is described by a half-filled Hubbard model; the second class is not strongly dimerized and is described by a quarter-filled extended Hubbard model. We argue that these models capture the essential physics of these materials. We explore the phase diagram of the half-filled quasi-two-dimensional organic charge transfer salts, focusing on the metallic and superconducting phases. We review work showing that the metallic phase, which has both Fermi liquid and 'bad metal' regimes, is described both quantitatively and qualitatively by dynamical mean field theory (DMFT). The phenomenology of the superconducting state is still a matter of contention. We critically review the experimental situation, focusing on the key experimental results that may distinguish between rival theories of superconductivity, particularly probes of the pairing symmetry and measurements of the superfluid stiffness. We then discuss some strongly correlated theories of superconductivity, in particular the resonating valence bond (RVB) theory of superconductivity. We conclude by discussing some of the major challenges currently facing the field. These include parameterizing minimal models, the evidence for a pseudogap from nuclear magnetic resonance (NMR) experiments, superconductors with low critical temperatures and extremely small superfluid stiffnesses, the possible spin- liquid states in kappa-(ET)(2)Cu-2(CN)(3) and beta'-[Pd(dmit)(2)](2)Z, and the need for high quality large single crystals.
