A qualitative analysis of the role of the Hospital in the Home registered nurse in Australia

BackgroundHealthcare and societal expectations change over time, with Hospital in the Home (HITH) registered nurses (RNs) increasing in community profile in Australian nursing domains. With increases in service demand and bed pressure creating an increased need for services outside the hospital environment understanding of the role of the registered nurse working in HITH is needed. AimThis research aims to identify the role and function of the RNs’ experience in their day-to-day work in the HITH setting. Additionally, the research shares a content analysis of the position descriptions of participating HITH RNs to analyse key performance indicator inclusions and barriers in scope of practice for the registered nurse. MethodUsing an interpretive phenomenological approach and Gadamer’s method, 12 HITH RN participants from across Australia were engaged in in-depth interviews. Interviews provided HITH RNs the opportunity to share their experience of the role and a contributing content analysis of position descriptions followed that provided a synopsis of key areas of commonality and difference. FindingsThree key areas emerged: professionalism, knowledge, and responsiveness, with an identified mismatch between generalisations in scope of practice in the position descriptions and the shared experience of the HITH RN participants. DiscussionThe research identified shared challenges exist in the day-to-day role and function of the HITH RN determining that HITH RNs undertake complex roles, working with generic position descriptions, often absent of core components of autonomous practice, experience, and knowledge. Limitations exist in the scope of practice of the HITH RN resulting in delays in care where advanced practice could be applied. What is known about the topic?•HITH registered nurses provide acute care in community.•HITH nursing education pathways and career progression in advanced practice is not formalised.•HITH nursing position descriptions are determined by each health service. What does this paper add?•First-hand understanding of the HITH RN experiences of role and scope working in Australia.•The HITH RN undertakes a complex role in the absence of an advanced practice model.•Highlights the need for consideration of career pathway planning and advanced practice pathways for HITH RNs.

Machine learning parameter systems, Noether normalisations and quasi-stable positions

We discuss the use of machine learning models for finding “good coordinates” for polynomial ideals. Our main goal is to put ideals into quasi-stable position, as this generic position shares most properties of the generic initial ideal, but can be deterministically reached and verified. Furthermore, it entails a Noether normalisation and provides us with a system of parameters. Traditional approaches use either random choices which typically destroy all sparsity or rather simple human heuristics which are only moderately successful. Our experiments show that machine learning models provide us here with interesting alternatives that most of the time make nearly optimal choices.

An improved complexity bound for computing the topology of a real algebraic space curve

We propose a new algorithm to compute the topology of a real algebraic space curve. The novelties of this algorithm are a new technique to achieve the lifting step which recovers points of the space curve in each plane fiber from several projections and a weaker notion of generic position. As distinct to previous work, our sweep generic position does not require that x-critical points have different x-coordinates. The complexity of achieving this sweep generic position property is thus no longer a bottleneck in term of complexity. The bit complexity of our algorithm is O˜(d18+d17τ) where d and τ bound the degree and the bitsize of the integer coefficients, respectively, of the defining polynomials of the curve and polylogarithmic factors are ignored. To the best of our knowledge, this improves upon the best currently known results at least by a factor of d2.

First complete Niobe yangtzeensis Lu, 1975 (Asaphidae, Trilobita) from the Middle Ordovician of South China, and its systematic and palaeogeographic implications

Since Niobe yangtzeensis was erected in 1975, due to no complete or even cephalic specimens, the generic assignment of Niobe yangtzeensis remains controversial. Based on the new discovery of a complete specimen of Niobe yangtzeensis in Yichang of South China, this species is redescribed and its generic position assignment is clarified and confirmed. A phylogenetic analysis of Niobinae shows that each of the four genera of this subfamily (Niobe, Niobella, Proxiniobe and Gog) forms a monophyletic group, and that among which Niobe yangtzeensis belongs to the genus Niobe. The palaeogeographical distribution and environmental analysis of Niobinae, suggest that Niobella, Proxiniobe and Gog lived in a relatively deeper-water (the outer-shelf or slope) environment, while Niobe preferred a shallower water environment, such as the inner shelf.

Sex-association experiments reveal the true identity of Physetopoda lampedusia (Invrea, 1957) (Hymenoptera, Mutillidae, Smicromyrmini).

Arthropod biodiversity is still insufficiently known in large areas of Europe, such as the Iberian Peninsula, regarding several insect groups. Mutillid wasps (Mutillidae), markedly sexually dimorphic ectoparasitic species, are poorly known Hymenoptera, with a number of species awaiting formal description and others known only from one sex. Sexual associations have been historically difficult to establish for most mutillid wasp species; in an European context, the species in tribe Smicromyrmini, particularly in the genera Smicromyrme Thomson, 1870 and Physetopoda Schuster, 1949, have presented the biggest challenges. In this paper, the hitherto unknown male of Physetopoda lampedusia (Invrea, 1957) is recognized as Ephutomma montarcense ((Mercet MS.) Giner Marí, 1944), with the former name falling into synonymy. A total of 63 females identified as P. lampedusia and 35 males identified as E. montarcense were collected in Portugal from 1999-2022. The correct sex association was confirmed through pairing experiments in captivity and is supported by circumstantial field observations in situ. Redescriptions of both male and female, as well as behavioural notes, are presented. Ephutomma montarcense is new for Portugal and its distribution is thus extended to Lampedusa Island (Italy) and Morocco, where it had been recorded as P. lampedusia, with Ephutomma representing a new genus for these three countries. The reliability of the method used, as well as the generic position and authorship of the species are briefly discussed.

The systematic position of Cryptopotamonanacoluthon (Kemp, 1918), with the description of a new species of Sinolapotamon Tai & Sung, 1975 (Crustacea, Decapoda, Brachyura, Potamidae) from southern China.

The systematics of the potamid freshwater crab Cryptopotamonanacoluthon (Kemp, 1918) is clarified, and its generic position in Sinolapotamon Tai & Sung, 1975, is confirmed based on morphological comparisons, geographical information and phylogenetic analyses. A new species of Sinolapotamon, Sinolapotamoncirratumsp. nov. is described from the Guangxi Zhuang Autonomous Region of China. Sinolapotamoncirratumsp. nov. is distinguished from its congeners by the combination of characters of its carapace, third maxilliped, anterolateral margin, and unique male first gonopod. Phylogenetic analyses based on partial COX1, 16S rRNA and 28S rRNA genes also support the species as new.

Taxonomy of Hyphodermella: a case study to show that simple phylogenies cannot always accurately place species in appropriate genera

The genus is a special and crucial taxonomic rank compared with others above the species level, because a species has to be placed in a certain genus instead of any other higher ranks. With more and more new species being described, the placements of their generic position are sometimes incorrect due to the simple phylogenies resulting from inappropriate sampling. Here, we focus on the taxonomy of a small wood-inhabiting fungal genus Hyphodermella. With the most comprehensive sampling to date, the phylogenetic position of Hyphodermella within Phanerochaetaceae is rearranged by employing the same ITS and nLSU regions as in previous studies and also the ITS, nLSU, rpb1, rpb2 and tef1α regions. Three species are excluded from Hyphodermella: H. poroides is placed in a newly introduced monotypic genus Pseudohyphodermella, while H. aurantiaca and H. zixishanensis are transferred to Roseograndinia. Hyphodermella suiae is described as a new species from South China and Vietnam. Keys to eight species in Hyphodermella and five in Roseograndinia are provided. Beyond solving the taxonomic issue of Hyphodermella itself, the current study also aims to suggest that all fungal taxonomists especially beginners should keep in mind to sample as many comprehensive taxa as possible in phylogenetic analyses.

Rediscovery and phylogenetic position of the glassfrog "Centrolene"acanthidiocephalum (Ruiz-Carranza and Lynch, 1989) (Anura: Centrolenidae)with the description of its advertisement call and comments on clutches and tadpoles.

The lack of basic natural history and distributional data represents a challenge for the conservation of rare and endemic amphibian species. This is the case of "Centrolene" acanthidiocephalum, a poorly known glassfrog endemic to the Cordillera Oriental of the Colombian Andes. This species was formally described in the late 1980s and no records have been reported over the last quarter century. Therefore, little is known about its distributional boundaries, morphological variation, natural history, and evolutionary relationships. Here we report the finding of a population of "Centrolene" acanthidiocephalum from a locality around its historical range and provide additional information on its geographic distribution, clutch size, and adult morphology. We also present for the first time data on tadpole morphology, as well as a description of its advertisement call and a phylogenetic tree based on mitochondrial genetic data corroborating its generic position within Centrolene.

Late Triassic (Late Early to Early Middle Norian) and Late Triassic or Early Jurassic Radiolarians from Limestone in the Tha Sao Area, Kanchanaburi Province, Western Thailand: Low-Latitude Fauna in the Eastern Tethys

Moderately-preserved Late Triassic (late early to early middle Norian) and Late Triassic or Early Jurassic radiolarians have been identified from two sections of limestone and dolomitic limestone, respectively in the Tha Sao area, Kanchanaburi Province in western Thailand. Previously these limestones have been assigned as the Permian because of the similarity of lithology without any fossil evidence. Section 1 is a succession of about 18 m in thickness, consisting of calcareous mudstone, micritic limestone, and dolomitic limestone, in ascending order. Section 2 is about 30 m in thickness and consisting of dolomitic limestone. Middle micritic limestone of about 10 m thick of Section 1 yielded diversified radiolarians. Dolomitic limestone of Section 2 yielded rare radiolarians from two levels. We identified radiolarians from five levels of micritic limestone and two levels of dolomitic limestone and totally identified 53 species belonging to 39 genera including two species of which generic position is uncertain and one new species Colum tekini Sashida and Ito sp. nov. At the Late Triassic time, the Tethys Ocean between Sibumasu and Indochina blocks almost closed due to the collision of these two continental blocks. Upper Triassic radiolarian-bearing limestones have been deposited in the eastern to western Tethyan areas within 35° of both hemispheres. The present radiolarian fauna is representative of low latitude Tethyan fauna. The faunal similarity between the eastern and western Tethys indicates the uniformity of the establishment of the low latitude fauna by the Late Triassic.

Additional Records of the Elusive Lateritic Plateau Toad <i>Beduka koynayensis</i> (Soman, 1963) (Anura: Bufonidae) from the Surroundings of its Type Locality with an Insight into the Genetic Data

The Koyna Toad, Beduka koynayensis, was described some 50 years ago as Bufo koynayensis. Due to taxonomic changes in the generic position now the species is considered under the recently established genus Beduka. Although the terrestrial toad species are morphologically cryptic and difficult to identify them based on morphological characters alone the members of Beduka are exceptions due to clear body colour patterns and habitat specificity. Even though the species is well studied in terms of reproductive biology, call pattern and life history traits there is a lacuna in the understandings of its range of distribution, morphological and genetic variations due to limited field samples available in the museums and the genetic data availability in the GenBank. Based on the fresh collections around the type locality, here we report morphological variations across the different populations within the species. With the 16S rRNA generated in the study discussions are made on the genetic variations across its range of distribution utilizing the unpublished sequences available in the GenBank.

On prescribing total orders for bipartite sets of distances in the Euclidean Plane

In this note we give a negative answer to a question proposed by Almendra-Hernández and Martínez-Sandoval. Let n ≤ m be positive integers and let X and Y be sets of sizes n and m in Rn-1 such that XUY is in generic position. There is a natural order on XxY induced by the distances between the corresponding points. The question is if all possible orders on XxY can be obtained in this way. We show that the answer is negative when n<m. The case n=m remains open.

The Kähler different of a 0-dimensional scheme

Given a 0-dimensional scheme [Formula: see text] in the projective [Formula: see text]-space [Formula: see text] over a field [Formula: see text], we are interested in studying the Kähler different of [Formula: see text] and its applications. Using the Kähler different, we characterize the generic position and Cayley–Bacharach properties of [Formula: see text] in several certain cases. When [Formula: see text] is in generic position, we prove a generalized version of the Apéry–Gorenstein–Samuel theorem about arithmetically Gorenstein schemes. We also characterize 0-dimensional complete intersections in terms of the Kähler different and the Cayley–Bacharach property.

Coprinus leucostictus Rediscovered after a Century, Epitypified, and Its Generic Position in Hausknechtia Resolved by Multigene Phylogenetic Analysis of Psathyrellaceae

About a century after the first finding in northern Vietnam (1908), Coprinus leucostictus is rediscovered on 12 localities in southern India and southern to southeastern China, growing in evergreen subtropical or tropical forests. It is morphologically a rather unique species with coprinoid basidiomata, strongly branched and diverticulate veil hyphae, and a hymeniderm pileipellis. The BLAST search of ITS and tef-1α sequences showed its close relationship to Hausknechtia floriformis, which is not clear based on morphological characters. Multigene phylogenetic analysis of a concatenated dataset of ITS, LSU, tef-1α, and β-tubulin sequences, revealed C. leucostictus and H. floriformis as separate, but sister species. Molecular phylogenetic relationships within the family Psathyrellaceae (including 17 genera) are presented in the phylogram. The genera Hausknechtia and Candolleomyces formed two well-supported lineages and were recovered as a monophyletic group. A total of 27 sequences from the genus Hausknechtia were newly generated in this study. Coprinus leucostictus is combined as Hausknechtia leucosticta, its epitype is designated, and the hitherto monotypic genus Hausknechtia is emended. A detailed morphological description of H. leucosticta supplemented with colour photographs and line drawings is provided.

Alloexidiopsis gen. nov., A Revision of Generic Delimitation in Auriculariales (Basidiomycota).

Auriculariales is a fungal order with highly diverse morphological traits of basidiomes, which partially leads to a poor understanding of its taxonomic system at the generic level. To identify our recently collected specimens of Auriculariales to a species level, we perform a comprehensive phylogenetic analysis of the generic relationships in Auriculariales. In association with morphological characteristics, a new genus Alloexidiopsis belonging to Auriculariaceae is erected with two new species, namely, A. australiensis and A. schistacea. Moreover, Exidiopsis calcea separated from the generic type E. effusa and Heteroradulum niveum and H. yunnanense recently inaccurately described as members of Heteroradulum are recovered in the clade of Alloexidiopsis. These three species are thus transferred to this new genus. One collection of Exidiopsis grisea also falls in the clade of Alloexidiopsis, whereas another collection of this species is separated far from Alloexidiopsis and E. effusa. Since we have no collection to confirm the species identity of E. grisea, its generic position is uncertain. The main taxonomic morphological differences among Alloexidiopsis and related corticioid genera in Auriculariales are summarized. A key to all the five accepted species of Alloexidiopsis is provided. As two unnamed lineages exist in Alloexidiopsis besides the abovementioned five species, it is assumed that more new species will be revealed from this genus under its current circumscription.

A Genus/Species Account of Scale‐Degree Qualia

ABSTRACTScale‐degree qualia are the fundamental building blocks of tonal cognition. Despite the recent flurry of scholarly activity surrounding their nature, certain conceptual entanglements persist. I argue that when scholars (and pedagogues) invoke the notion of scale degrees, they typically conflate two subcomponents of scale‐degree experience – which I call ‘generic scalar position’ and ‘specific modal character’ – and treat them as if they were one composite thing. In response, I propose an ordered‐triple notation for labelling scale degrees that insists on the representational separation of these two subcomponents, and I demonstrate through a series of analytical vignettes that conceiving of scale degrees in this manner can shed new light on a variety of common musical scenarios, from local tonicisations to large‐scale modulations to moments of tonal/modal ambiguity. This ordered‐triple notation is intentionally designed for a flexible domain of application, not just to European tonal music but also to Western popular music and more generally to any music in any of the seven diatonic modes.

Generalized Formulation for the Behavior of Geometrically Curved and Twisted Three-Dimensional Timoshenko Beams and Its Isogeometric Analysis Implementation

Abstract This article presents a novel derivation for the governing equations of geometrically curved and twisted three-dimensional Timoshenko beams. The kinematic model of the beam was derived rigorously by adopting a parametric description of the axis of the beam, using the local Frenet–Serret reference system, and introducing the constraint of the beam cross ection planarity into the classical, first-order strain versus displacement relations for Cauchy’s continua. The resulting beam kinematic model includes a multiplicative term consisting of the inverse of the Jacobian of the beam axis curve. This term is not included in classical beam formulations available in the literature; its contribution vanishes exactly for straight beams and is negligible only for curved and twisted beams with slender geometry. Furthermore, to simplify the description of complex beam geometries, the governing equations were derived with reference to a generic position of the beam axis within the beam cross section. Finally, this study pursued the numerical implementation of the curved beam formulation within the conceptual framework of isogeometric analysis, which allows the exact description of the beam geometry. This avoids stress locking issues and the corresponding convergence problems encountered when classical straight beam finite elements are used to discretize the geometry of curved and twisted beams. Finally, this article presents the solution of several numerical examples to demonstrate the accuracy and effectiveness of the proposed theoretical formulation and numerical implementation.

Receiver-Coil Location Detection in a Dynamic Wireless Power Transfer System for Electric Vehicle Charging.

Receiver position sensing is investigated in a dynamic wireless power transfer (DWPT) system for electric vehicle (EV) charging. Exploiting the peculiar behaviour of the resonator arrays input impedance, it is possible to identify the position of the receiver coil by exciting the first array resonator with a signal at a proper frequency and measuring the resulting current. An analytical expression of the input impedance of the resonator array coupled with the EV receiver coil placed in a generic position is provided; its sensitivity to different circuit parameters is also analysed. The outline of a simple and effective algorithm for the localization of the EV is proposed and applied to a test case.

Mooring system stiffness: A six-degree-of-freedom closed-form analytical formulation

A mooring system project is an iterative process, involving design and analysis with numerous parameters. In this context, analytical tools can help to reduce the use of expensive and time consuming full nonlinear numerical simulations based on high-order hierarchical models such as Finite Element models, mainly during early stages of the design. By employing Analytical Mechanics approaches, the present article brings an analytical and closed-mathematical-form formulation to determine the six-degree-of-freedom (DOF) mooring system stiffness matrix at any generic position of the floating body, provided mooring line forces are modeled as conservative ones. In order to demonstrate the use of these tools, the international benchmark of the OC4-DeepCwind platform is considered as a case study. The influence of the vessel mean position and design parameters in the stiffness, natural periods and oscillation modes is studied, revealing interesting coupling effects. Results are benchmarked against the commercial code OrcaFlexTM showing good agreement, observing that the analytical result requires much less computational cost.

Delongia flavolimbata (S.He & Y.J.Yi) S.He & Y.J.Yi, an unusual species with elamellate laminae from China, newly combined in Polytrichaceae based on molecular data

ABSTRACT Introduction Hyophila flavolimbata S.He & Y.J.Yi has several unusual morphological features that cast doubt on its current generic position in Hyophila and even its family placement in the Pottiaceae. The results of a molecular study carried out to investigate the taxonomic identity of this taxon have provided a unique resolution. Methods In addition to a morphological examination in which material from related species were compared, rps4 and trnL–F sequences from the type specimen and a newly identified specimen of Hyophila flavolimbata were analysed. Relationships between related species in the Polytrichaceae were explored using Maximum Likelihood and Bayesian inference analyses. Key results and conclusions Phylogenetic analysis resolved a new taxonomic position for Hyophila flavolimbata in the genus Delongia of the Polytrichaceae, and consequently, a new combination, Delongia flavolimbata (S.He & Y.J.Yi) S.He & Y.J.Yi, is made. Photographs detailing key morphological differences from related taxa, and a key to the three currently recognised species in Delongia, are provided. The completely elamellate laminae of this species are an unusual morphological character that is highly remarkable for Delongia and uncommon in the Polytrichaceae.
