A pedagogical framework for facilitating parents’ learning in nurse–parent partnership

© 2017 John Wiley & Sons Ltd Nursing work increasingly demands forms of expertise that complement specialist knowledge. In child and family nursing, this need arises when nurses work in partnership with parents of young children at risk. Partnership means working with parents in respectful, negotiated and empowering ways. Existing partnership literature emphasises communicative and relational skills, but this paper focuses on nurses’ capacities to facilitate parents’ learning. Referring to data from home visiting, day-stay and specialist toddler clinic services in Sydney, a pedagogical framework is presented. Analysis shows how nurses notice aspects of children, parents and parent–child interactions as a catalyst for building on parents’ strengths, enhancing guided chance or challenging unhelpful constructs. Prior research shows the latter can be a sticking point in partnership, but this paper reveals diverse ways in which challenges are folded into learning process that position parents as agents of positive change. Noticing is dependent on embodied and communicative expertise, conceptualised in terms of sensory and reported channels. The framework offers a new view of partnership as mind-expanding for the parent and specifies the nurse's role in facilitating this process

Endangered Practices: Writing Feminist Research

Thisbrief sketch serves as a framing for the focus of this chapter, which is concerned with the conditions under which feminist research can be done in current times. This chapter is a co-production between a senior academic and two doctoral students, engaged in supervision and joint writing about feminist- scholarship. We aim to contribute to a discussion about the terms and conditions in which feminist research can be done in the university today, with a particular focus on the "practice disciplines"

Synaptic inhibition in the lateral habenula shapes reward anticipation

The lateral habenula (LHb) supports learning processes enabling the prediction of upcoming rewards. While reward-related stimuli decrease the activity of LHb neurons, whether this anchors on synaptic inhibition to guide reward-driven behaviors remains poorly understood. Here, we combine in vivo two-photon calcium imaging with Pavlovian conditioning in mice and report that anticipatory licking emerges along with decreases in cue-evoked calcium signals in individual LHb neurons. In vivo multiunit recordings and pharmacology reveal that the cue-evoked reduction in LHb neuronal firing relies on GABAA-receptor activation. In parallel, we observe a postsynaptic potentiation of GABAA-receptor-mediated inhibition, but not excitation, onto LHb neurons together with the establishment of anticipatory licking. Finally, strengthening or weakening postsynaptic inhibition with optogenetics and GABAA-receptor manipulations enhances or reduces anticipatory licking, respectively. Hence, synaptic inhibition in the LHb shapes reward anticipation. Keywords: GABA(A) receptors; cue-reward associative behavior; lateral habenula; synaptic inhibition; synaptic plasticit

Morphine withdrawal recruits lateral habenula cytokine signaling to reduce synaptic excitation and sociability.

The lateral habenula encodes aversive stimuli contributing to negative emotional states during drug withdrawal. Here we report that morphine withdrawal in mice leads to microglia adaptations and diminishes glutamatergic transmission onto raphe-projecting lateral habenula neurons. Chemogenetic inhibition of this circuit promotes morphine withdrawal-like social deficits. Morphine withdrawal-driven synaptic plasticity and reduced sociability require tumor necrosis factor-α (TNF-α) release and neuronal TNF receptor 1 activation. Hence, habenular cytokines control synaptic and behavioral adaptations during drug withdrawal

The influence of Galactic aberration on precession parameters determined from VLBI observations

The influence of proper motions of sources due to Galactic aberration on precession models based on VLBI data is determined. Comparisons of the linear trends in the coordinates of the celestial pole obtained with and without taking into account Galactic aberration indicate that this effect can reach 20 $\mu$as per century, which is important for modern precession models. It is also shown that correcting for Galactic aberration influences the derived parameters of low-frequency nutation terms. It is therefore necessary to correct for Galactic aberration in the reduction of modern astrometric observations

The SN 393 -- SNR RX J1713.7-3946 (G347.3-0.5) Connection

Although the connection of the Chinese "guest" star of 393 AD with the Galactic supernova remnant RX J1713.7-3946 (G347.3-0.5) made by Wang et al. in 1997 is consistent with the remnant's relatively young properties and the guest star's projected position within the `tail' of the constellation Scorpius, there are difficulties with such an association. The brief Chinese texts concerning the 393 AD guest star make no comment about its apparent brightness stating only that it disappeared after 8 months. However, at the remnant's current estimated 1 - 1.3 kpc distance and A_v ~ 3 mag, its supernova should have been a visually bright object at maximum light (-3.5 to -5.0 mag) and would have remained visible for over a year. The peak brightness ~ 0 magnitude adopted by Wang et al. and others would require the RX J1713.7-3946 supernova to have been a very subluminous supernova event similar to or fainter than CCSNe like SN 2005cs. We also note problems connecting SN 393 with a European record in which the Roman poet Claudian describes a visually brilliant star in the heavens around 393 AD that could be readily seen even in midday. Although several authors have suggested this account may be a reference to the Chinese supernova of 393, Scorpius would not be visible near midday in March when the Chinese first reported the 393 guest star. We review both the Chinese and Roman accounts and calculate probable visual brightnesses for a range of supernova subtypes and conclude that neither the Chinese nor the Roman descriptions are easily reconciled with an expected RX J1713.7-3946 supernova brightness and duration.Comment: 7 pages includes 2 tables.

Interstellar Grains -- The 75th Anniversary

The year of 2005 marks the 75th anniversary since Trumpler (1930) provided the first definitive proof of interstellar grains by demonstrating the existence of general absorption and reddening of starlight in the galactic plane. This article reviews our progressive understanding of the nature of interstellar dust.Comment: invited review article for the "Light, Dust and Chemical Evolution" conference (Gerace, Italy, 26--30 September 2004), edited by F.

Pore Systems in Arab D Limestone Spectral Analysis of the Arab D Limestone Pore

The pore systems of the Arab D limestone, a formation that holds a large proportion of the world’s oil reserves, show abundant microporosity. Prior petrographic studies are continued here with an extensive mercury injection capillary pressure study. The MICP study demonstrates that the pore volume of the micropores (~25 % of pore space) is volumetrically significant. Using Thomeer type curve analysis to fit the MICP data of our very large MICP data set, the pore systems ’ volumes and entry pressures are quantified. The micropores are shown to be oil-charged and do not contribute measurably to permeability. The MICP entry pressure data show four distinct entry pressure modes or “porositons, ” three of which represent forms of microporosity. The Arab D limestone matrix pore system, therefore, requires a multimodal matrix storage model and a monomodal matrix permeability model. Having determined the nature of the embedded carbonate pore system modes, the petrophysical model is rebuilt for the relationship of the entry pressure modes to the depositional geology, spectral porosity log response, hydrocarbon storage, permeability and multiphase transport,and microscopic displacement efficiency. The conventional experimental data must be analyzed using new multimodal methods and algorithms. Permeability is shown to be controlled by the properties of the mode containing the largest of the maximum pore throat diameters. The Type 1 microporosity is shown to shift the imbibition cycle oil relative permeability curve to the right and hence affect the determination of the microscopic displacement efficiency in the presence of macro and micropores.
