Comparison of Nurse Staffing Based on Changes in Unit-level Workload Associated with Patient Churn
Aim
This analysis compares the staffing implications of three measures of nurse staffing requirements: midnight census, turnover adjustment based on length of stay, and volume of admissions, discharges and transfers. Background
Midnight census is commonly used to determine registered nurse staffing. Unit-level workload increases with patient churn, the movement of patients in and out of the nursing unit. Failure to account for patient churn in staffing allocation impacts nurse workload and may result in adverse patient outcomes. Method(s)
Secondary data analysis of unit-level data from 32 hospitals, where nursing units are grouped into three unit-type categories: intensive care, intermediate care, and medical surgical. Result
Midnight census alone did not account adequately for registered nurse workload intensity associated with patient churn. On average, units were staffed with a mixture of registered nurses and other nursing staff not always to budgeted levels. Adjusting for patient churn increases nurse staffing across all units and shifts. Conclusion
Use of the discharges and transfers adjustment to midnight census may be useful in adjusting RN staffing on a shift basis to account for patient churn. Implications for nursing management
Nurse managers should understand the implications to nurse workload of various methods of calculating registered nurse staff requirements
The development of direct payments in the UK: implications for social justice
Direct payments have been heralded by the disability movement as an important means to
achieving independent living and hence greater social justice for disabled people through
enhanced recognition as well as financial redistribution. Drawing on data from the ESRC
funded project Disabled People and Direct Payments: A UK Comparative Perspective,
this paper presents an analysis of policy and official statistics on use of direct payments
across the UK. It is argued that the potential of direct payments has only partly been
realised as a result of very low and uneven uptake within and between different parts
of the UK. This is accounted for in part by resistance from some Labour-controlled local
authorities, which regard direct payments as a threat to public sector jobs. In addition,
access to direct payments has been uneven across impairment groups. However, from a
very low base there has been a rapid expansion in the use of direct payments over the
past three years. The extent to which direct payments are able to facilitate the ultimate
goal of independent living for disabled people requires careful monitoring
A Purely Functional Computer Algebra System Embedded in Haskell
We demonstrate how methods in Functional Programming can be used to implement
a computer algebra system. As a proof-of-concept, we present the
computational-algebra package. It is a computer algebra system implemented as
an embedded domain-specific language in Haskell, a purely functional
programming language. Utilising methods in functional programming and prominent
features of Haskell, this library achieves safety, composability, and
correctness at the same time. To demonstrate the advantages of our approach, we
have implemented advanced Gr\"{o}bner basis algorithms, such as Faug\`{e}re's
and , in a composable way.Comment: 16 pages, Accepted to CASC 201
Use of Digital Tools for Horizontal Spread of Agricultural Technologies by Farmers of Kerala
In this digital era, integration of digital tools is common in every sector and agriculture is not an exception. The present study was conducted among the farmers of Kerala who were using various digital tools, during the year 2018-2019. The sample of the study consisted of 120 farmers from three zones of Kerala. Awareness and Preference of the respondents were studied in order to find out the horizontal spread. Based on the results obtained it was found that all farmers were aware about tools like television, mobile phone and social media. Most of the farmers had selected mobile phones as the most preferred tool. Farmers were found to use mobile phones mainly for âcrop protectionâ purposes and social media for âmarketingâ purposes
Benchmarking acid and base dopants with respect to enabling the ice V to XIII and ice VI to XV hydrogen-ordering phase transitions
Doping the hydrogen-disordered phases of ice V, VI and XII with hydrochloric
acid (HCl) has led to the discovery of their hydrogen-ordered counterparts ices
XIII, XV and XIV. Yet, the mechanistic details of the hydrogen-ordering phase
transitions are still not fully understood. This includes in particular the
role of the acid dopant and the defect dynamics that it creates within the
ices. Here we investigate the effects of several acid and base dopants on the
hydrogen ordering of ices V and VI with calorimetry and X-ray diffraction. HCl
is found to be most effective for both phases which is attributed to a
favourable combination of high solubility and strong acid properties which
create mobile H3O+ defects that enable the hydrogen-ordering processes.
Hydrofluoric acid (HF) is the second most effective dopant highlighting that
the acid strengths of HCl and HF are much more similar in ice than they are in
liquid water. Surprisingly, hydrobromic acid doping facilitates hydrogen
ordering in ice VI whereas only a very small effect is observed for ice V.
Conversely, lithium hydroxide (LiOH) doping achieves a performance comparable
to HF-doping in ice V but it is ineffective in the case of ice VI. Sodium
hydroxide, potassium hydroxide (as previously shown) and perchloric acid doping
are ineffective for both phases. These findings highlight the need for future
computational studies but also raise the question why LiOH-doping achieves
hydrogen-ordering of ice V whereas potassium hydroxide doping is most effective
for the 'ordinary' ice Ih.Comment: 18 pages, 7 figures, 1 tabl
Model for U.S. Farm Financial Adjustment Analysis of Alternative Public Policies
As the agricultural sector adjusts to financial stress and constantly changing national and international policies, additional structural changes are expected. The capacity for adjustment through existing agricultural asset markets depends on both the extent of farm restructuring and the resiliency of the markets and agricultural institutions. Research is needed to estimate farm financial restructuring needs and the expected duration of the restructuring process. Projecting the magnitude of change needed for financial stability in agriculture would help in assessing the ability of existing markets and institutions to manage restructuring. Policies to alleviate farm financial stress could then be judged for appropriateness and effectiveness
Capacitively coupled hydrogen discharges : modeling vs. experiment
This paper presents a systematic characterization of hydrogen capacitively coupled very high frequency discharges, produced within a parallel plate cylindrical setup, by comparing numerical simulations to experimental measurements for various plasma parameters. A good quantitative agreement is found between calculation and experiment for the coupled electrical power and the plasma potential, at various frequencies, pressures and applied voltages. However, the model generally underestimates the electron density and the self-bias potential with respect to measured values. Model predictions for the absolute density of H(n=1) atoms are compared to first diagnostic results, obtained by two-photon absorption laser-induced fluorescence diagnostics at various pressures and frequencies.Fundação para a CiĂȘncia e a Tecnologia (FCT) - SFRH/BD/5012/200
Modelling the influence of frequency in a low pressure capacitively coupled hydrogen discharge
This paper investigates the dependence of plasma density and self-bias voltage with excitation frequency (13.56-40.68 MHz) using a two-dimensional (2D) fluid model in a low pressure (300 mTorr) radio frequency (RF) capacitively coupled hydrogen discharge. A comparison with experimental results reveals that the model predicts the correct trends of density and self-bias voltage variation with driving frequenc
Modelling and characterization of a low pressure capacitively coupled hydrogen discharge
This paper presents a systematic characterization of a pure hydrogen capacitively coupled radio frequency discharge, produced in a parallel plate cylindrical setup, comparing experimental measurements obtained for such discharge with numerical simulations. A good agreement is found between simulation results and experimental measurements for the discharge main electrical parameters. A comparison of H atom absolute density LIF measurements with simulation results will also be presented
High Resolution HST-STIS Spectra of CI and CO in the Beta Pictoris Circumstellar Disk
High resolution FUV echelle spectra showing absorption features arising from
CI and CO gas in the Beta Pictoris circumstellar (CS) disk were obtained on
1997 December 6 and 19 using the Space Telescope Imaging Spectrograph (STIS).
An unsaturated spin-forbidden line of CI at 1613.376 A not previously seen in
spectra of Beta Pictoris was detected, allowing for an improved determination
of the column density of CI at zero velocity relative to the star (the stable
component), N = (2-4) x 10^{16} cm^{-2}. Variable components with multiple
velocities, which are the signatures of infalling bodies in the Beta Pictoris
CS disk, are observed in the CI 1561 A and 1657 A multiplets. Also seen for the
first time were two lines arising from the metastable singlet D level of
carbon, at 1931 A and 1463 A The results of analysis of the CO A-X (0-0),
(1-0), and (2-0) bands are presented, including the bands arising from {13}^CO,
with much better precision than has previously been possible, due to the very
high resolution provided by the STIS echelle gratings. Only stable CO gas is
observed, with a column density N(CO) = (6.3 +/- 0.3) x 10^{14} cm{-2}. An
unusual ratio of the column densities of {12}^CO to {13}^CO is found (R = 15
+/- 2). The large difference between the column densities of CI and CO
indicates that photodissociation of CO is not the primary source of CI gas in
the disk, contrary to previous suggestion.Comment: 13 pages, including 6 figures. LaTex2e (emulateapj5.sty). Accepted
