浅谈护士长非权力影响力与护理人员工作投入水平的关系
Objective: To explore the effects of the headnurses’ non-power influenceon the nurses’ work engagement. Methods: To conduct a questionnaire survey on 450 nurses of the clinical nursing units of The Peoples' Hospital of Jilin Province.Results: The non-power influence of the headnurseshave a director indirect positive influence on thenurses’ work engagement. Conclusion: The hospitals and nursing managers should take effective measures to promote the non-power influence, then to promote the level of nursing staffs’ work engagement, to organize and promote the nursing work of the hospital. 目的 探讨护士长非权力影响力对护士工作投入的影响。方法 对吉林省人民医院临床护理单元450名护士进行护士长非权力影响力量表和护理人员工作投入量表的问卷调查。 结果 护士长非权力影响力对护理人员工作投入具有直接和间接的正性影响。结论 医院和护理管理者应采取有效的措施提升非权力影响力,进而提升护理人员的工作投入水平,组织和推动医院护理工作
Fair Text-to-Image Diffusion via Fair Mapping
In this paper, we address the limitations of existing text-to-image diffusion
models in generating demographically fair results when given human-related
descriptions. These models often struggle to disentangle the target language
context from sociocultural biases, resulting in biased image generation. To
overcome this challenge, we propose Fair Mapping, a flexible, model-agnostic,
and lightweight approach that modifies a pre-trained text-to-image diffusion
model by controlling the prompt to achieve fair image generation. One key
advantage of our approach is its high efficiency. It only requires updating an
additional linear network with few parameters at a low computational cost. By
developing a linear network that maps conditioning embeddings into a debiased
space, we enable the generation of relatively balanced demographic results
based on the specified text condition. With comprehensive experiments on face
image generation, we show that our method significantly improves image
generation fairness with almost the same image quality compared to conventional
diffusion models when prompted with descriptions related to humans. By
effectively addressing the issue of implicit language bias, our method produces
more fair and diverse image outputs
Poly[μ2-aqua-diaqua(μ8-3-nitrobenzene-1,2-dicarboxylato)(μ6-3-nitrobenzene-1,2-dicarboxylato)tetrasodium]
In the title layered coordination polymer, [Na4(C8H3NO6)2(H2O)3]n, the doubly deprotonated 3-nitrobenzene-1,2-dicarboxylate ligands exhibit μ8- and μ6-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octahedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. One of the nitro groups is disordered over two sets of sites with site-occupancy factors 0.580 (8):0.419 (2). A network of O—H⋯O and O—H⋯N hydrogen bonds helps to establish the packing
2-[(E)-(2-Hydroxynaphthalen-1-yl)methylideneamino]isoindoline-1,3-dione
The title compound, C19H12N2O3, has two independent molecules (A and B) in the asymmetric unit. There is an intramolecular O—H⋯N hydrogen bond in each molecule. The mean planes of the naphthalene [maximum deviations = 0.024 (3) and 0.030 (3) Å in A and B, respectively] and the isoindoline units [maximum deviations 0.009 (3) and 0.008 (3) Å in A and B, respectively] are almostly coplanar, with dihedral angles of 4.25 (9) ad 3.84 (9)° in molecules A and B, respectively. The two independent molecules are connected by π–π interactions [centroid-centroid distances 3.5527 (19) and 3.5627 (19) Å]. In the crystal, the A+B pairs are further connected via π–π interactions [centroid–centroid distances = 3.693 (2)–3.831 (2) Å], leading to the formation of columns propagating along the a-axis direction. The columns are linked via C—H⋯O interactions, leading to the formation of a three-dimensional network
Magnetic Fields and Infall Motions in NGC 1333 IRAS 4
We present single-dish 350 micron dust continuum polarimetry as well as HCN
and HCO+ J=4-3 rotational emission spectra obtained on NGC 1333 IRAS 4. The
polarimetry indicates a uniform field morphology over a 20" radius from the
peak continuum flux of IRAS 4A, in agreement with models of magnetically
supported cloud collapse. The field morphology around IRAS 4B appears to be
quite distinct however, with indications of depolarization observed towards the
peak flux of this source. Inverse P-Cygni profiles are observed in the HCN
J=4-3 line spectra towards IRAS 4A, providing a clear indication of infall gas
motions. Taken together, the evidence gathered here appears to support the
scenario that IRAS 4A is a cloud core in a critical state of support against
gravitational collapse.Comment: 23 pages, 6 figures, 2 table
FeS2 monolayer: a high valence and high- Ising ferromagnet
Two-dimensional (2D) magnetic materials are of current great interest for
their promising applications in spintronics. Strong magnetic coupling and
anisotropy are both highly desirable for the achievement of a high temperature
magnetic order. Here we propose the unusual high valent FeS hexagonal
monolayer as such a candidate for a strong Ising 2D ferromagnet (FM), by
spin-orbital state analyses, first-principles calculations, and the
renormalized spin-wave theory (RSWT). We find that very importantly, the high
valent Fe ion is in the low-spin state (, =1) with
degenerate orbitals rather than the high-spin state
(, =2). It is the low-spin state that allows to carry a
large perpendicular orbital moment and then produces a huge single ion
anisotropy (SIA) of 25 meV/Fe. Moreover, the negative charge transfer character
associated with the unusual high valence, strong Fe -S hybridization,
wide bands, and a small band gap all help to establish a strong superexchange.
Indeed, our first-principles calculations confirm the strong FM superexchange
and the huge perpendicular SIA, both of which are further enhanced by a
compressive strain. Then, our RSWT calculations predict that the FM
is 261 K for the pristine FeS monolayer and could be increased to 409 K
under the compressive --5\% strain. The high is also reproduced by
our Monte Carlo (MC) simulations. Therefore, it is worth exploring the
high- Ising FMs in the high valent 2D magnetic materials with
degenerate orbitals.Comment: 13 pages, 5 figure
