The Moment of Caring: a Manuscript for Reflection on Caring Moments in Nursing Practice

<p>The focus of this study was on understanding the caring nature of the nurse-client relationship as reflected in a story of nursing practice. The story was examined and understood using an interpretive approach which emerged over time and reflected the exploratory and intuitive nature of the work. The processes of reflection, immersion and crystallisation were used to generate an exploratory theoretical work on caring. The method was called 'The Hermeneutic Wave' because it focused on interpreting and understanding textual reflection of experience, and reflected the ebb and flow nature of the processes of interpretation used. These tidal processes involved moving out of the story to conceptualise what was occurring within the story from a general perspective, and then re-layering the conceptualisations back over the story to examine congruity and differences, and to uncover understanding and meaning of practice. These processes were repeated until 'The Moment of Caring: A Manuscript for Reflection on Caring Moments in Nursing Practice' emerged. The manuscript consists of four phases; Phase One - Readiness to Co-participate, where the nurse and client fulfil expected health related roles and their relationship is characterised as one of apartness where they are relating in regard to their distinct roles; Phase Two - In Relationship, where the nurse and client are in the process of moving from a relationship characterised by apartness to that of oneness where they relate as person-to-person; Phase Three - 'The Moment of Caring', where the nurse and client transcend relating from a position of apartness and relate as one; and Phase Four - Redefining Wholeness, where the nurse's and client's understanding of their shared experience results in growth in their beings, and where their relationship moves from oneness to apartness in response to this growth. The manuscript 'The Moment of Caring' provides nurses with a framework for reflection in as well as on nursing practice, offers an emerging exploratory approach to the development of theory from practice, and contributes to the growing body of knowledge of caring within nursing practice in New Zealand and internationally.</p>

Determination Of Lunar-Solar Deformation Processes In The Geomedium Volume In The Conditions Of Megapolis

The paper describes a new borehole hardware-software complex designed for synchronous registration of geoacoustic emission signals, electromagnetic radiation, temperature and borehole device rotation angle. The results of regime measurements with the new equipment in megapolis conditions are shown. The analysis of the obtained data is performed. The spectral-time analysis of regime measurements of geoacoustic emission and electromagnetic radiation signals registered in the borehole at a depth of 274 m was carried out. In the spectra of signals of electromagnetic radiation and geoacoustic emission the main diurnal and semidiurnal deformation tidal processes of known physical nature were identified.

Sedimentary signals of fluvial discharge variability under tide and wave influence: Miocene examples in NW Borneo

&lt;p&gt;The interaction of river and marine processes in the fluvial to marine transition zone (FMTZ) fundamentally impacts sedimentary dynamics and deposition. Heterolithics are important facies within ancient and modern FMTZs but the preserved signal of river flood, wave and tidal variations in heterolithics remains uncertain. This study integrates facies and ichnofacies characteristics of heterolithics in the Lambir Formation (Baram Delta Province, NW Borneo), with information of larger-scale stratigraphic architecture and modern analogue information, to interpret the preserved record of river flood deposits under the influence of tides and waves in an ancient FMTZ. Within the FMTZ of distributary channels, interpreted proximal&amp;#8211;distal sedimentological and stratigraphic trends suggest: (1) a proximal fluvial-dominated, tide-influenced subzone; (2) a distal fluvial- to wave-dominated subzone; and (3) a conspicuously absent tide-dominated subzone. During coupled storm and river floods, fluvial processes dominated the FMTZ along major and minor distributary channels and channel mouths, causing significant overprinting of preceding interflood deposits and deposition of thicker, sandier event beds. Intervening interflood deposits are muddier, with increased bioturbation, and may variably preserve sedimentary indicators of tide and wave processes. Despite interpreted fluvial&amp;#8211;tidal channel units and mangrove influence implying tidal processes, there is a paucity of unequivocal tidal indicators (e.g. cyclical heterolithic layering). This suggests that process preservation in the FMTZ preserved in the Lambir Formation primarily records episodic (flashy) river discharge, river flood and storm overprinting of tidal processes, and possible backwater dynamics.&amp;#160;&lt;/p&gt;

Tides on a Snowball

&lt;p&gt;The severe &amp;#8220;Snowball Earth&amp;#8221; glaciations proposed to have existed during the Cryogenian period (720 to 635 million years ago) coincided with the breakup of one supercontinent (Rodinia) and assembly of another (Pannotia). The presence of extensive continental ice sheets should theoretically lead to a tidally energetic Snowball ocean due to the reduced ocean depth, as was the case during the last glaciations, but the theory of the supertidal cycle suggests that the supercontinent paleogeography should lead to weak tides because the surrounding ocean is too large to host tidal resonances. So which theory is correct? Using an established numerical global tidal model and 22 paleogeographic reconstructions spanning 750-600Ma, we show that the Cryogenian ocean hosted diminished tidal amplitudes and associated energy dissipation rates, reaching 10-50% of today&amp;#8217;s rates, during the Snowball glaciations. In contrast, the tides were more energetic during the ice-free periods, and we propose that the near-absence of Cryogenian tidal processes may have been one contributor to the prolonged glaciations if these were near-global. These results also constrain lunar distance and orbital evolution throughout the Cryogenian and highlight that simulations of past oceans should include explicit tidally driven mixing processes.&lt;/p&gt;

Weak tides during Cryogenian glaciations

The severe “Snowball Earth” glaciations proposed to have existed during the Cryogenian period (720 to 635 million years ago) coincided with the breakup of one supercontinent and assembly of another. Whereas the presence of extensive continental ice sheets predicts a tidally energetic Snowball ocean due to the reduced ocean depth, the supercontinent palaeogeography predicts weak tides because the surrounding ocean is too large to host tidal resonances. Here we show, using an established numerical global tidal model and paleogeographic reconstructions, that the Cryogenian ocean hosted diminished tidal amplitudes and associated energy dissipation rates, reaching 10–50% of today’s rates, during the Snowball glaciations. We argue that the near-absence of Cryogenian tidal processes may have been one contributor to the prolonged glaciations if these were near-global. These results also constrain lunar distance and orbital evolution throughout the Cryogenian, and highlight that simulations of past oceans should include explicit tidally driven mixing processes.

Tides: A Very Short Introduction

The tide is the greatest synchronized movement of matter on our planet. Every drop of seawater takes part in tidal motion, driven by the gravitational pull of the Moon and Sun. Tides: A Very Short Introduction blends clear explanations of well-known tidal phenomena with recent insights into the dynamics of the deep ocean and coastal seas, considering the tide’s nature and causes, its observation and prediction, and unusual tides and their relevance. It explains the importance of ocean tidal mixing as a key part of our planet’s climate-control system and for enhancing biological productivity. It also considers the effects of tidal processes beyond our own planet on the moons of Jupiter and Saturn.

A detailed study of Andromeda XIX, an extreme local analogue of ultradiffuse galaxies

ABSTRACT With a central surface brightness of μ0 = 29.3 mag arcsec−2, and half-light radius of $r_{\rm half}=3.1^{+0.9}_{-1.1}$ kpc, Andromeda XIX (And XIX) is an extremely diffuse satellite of Andromeda. We present spectra for ∼100 red giant branch stars in this galaxy, plus 16 stars in a nearby stellar stream. With this exquisite data set, we re-derive the properties of And XIX, measuring a systemic velocity of 〈vr〉 = −109.0 ± 1.6 km s−1 and a velocity dispersion of $\sigma _{vr} = 7.8^{+1.7}_{-1.5}$ km s−1 (higher than derived in our previous work). We marginally detect a velocity gradient along the major axis of $\frac{{\rm d} v}{{\rm d}\chi }= -2.1\pm 1.8~{\rm km\, s}^{-1}$ kpc−1. We find its mass-to-light ratio is higher than galaxies of comparable stellar mass (${}[M/L]_{\rm half} = 278^{+146}_{-198}\, \mathrm{M}_\odot /\mathrm{L}_\odot$), but its dynamics place it in a halo with a similar total mass to these galaxies. This could suggest that And XIX is a ‘puffed up’ dwarf galaxy, whose properties have been altered by tidal processes, similar to its Milky Way counterpart, Antlia II. For the nearby stream, we measure $v_r=-279.2\pm 3.7~{\rm km\, s}^{-1}$, and $\sigma _v=13.8^{+3.5}_{-2.6}~{\rm km\, s}^{-1}$. We measure its metallicity, and find it to be more metal rich than And XIX, implying that the two features are unrelated. Finally, And XIX’s dynamical and structural properties imply it is a local analogue to ultradiffuse galaxies (UDGs). Its complex dynamics suggest that the masses of distant UDGs measured from velocity dispersions alone should be carefully interpreted.

A Case Study: Response Mechanics of Irregular Rotational Tidal Flows to Outlet Regulation in Yangtze Estuary

Responses of irregular rotational tidal flows to an outlet regulation (the Guyuan Sand (GYS) regulation) in the three-level branching Yangtze Estuary are studied by a high-resolution numerical model and theoretical analysis. The project is launched around GYS at the outlet of the North Branch of the Yangtze Estuary. The tidal flows around GYS are rotational and become irregular under the influences of the runoff-tide interactions, rapidly varying topographies and complex solid boundaries in coastal areas. Three designs of GYS regulation were studied, including various diversion dikes and new outlets of different widths. The regulation disturbs the irregular rotational flows around GYS, and further changes the estuarine tidal processes and the water exchange between different branches of the branching Yangtze Estuary. It was interesting to find that additional current and additional storage are formed along the North Branch when a southward outlet and the clockwise rotational flow met around GYS. This special phenomenon is named “guide effect” in this study. The guide effect, together with common resist effect (arising from the narrowed outlet channel), reshapes the estuarine tidal processes. Based on the simulation result and a theoretical analysis, response mechanics of irregular rotational tidal flows to the outlet regulation in complex branching estuaries are quantitatively studied.
