Rituals of Vocational Socialisation: Faith-Building in Higher Vocational Education for Weak-Form Occupational Pathways
Authors: Ye Rebecca 
Published: March 2021

AbstractThis paper addresses the question of how higher vocational education and training programmes socialise participants for future work, where the occupational pathways they are to embark on are weakly defined. The analysis focuses on organisational rituals as a means to understand individual and collective transformative processes taking place at a particular intersection of education and labour markets. Building on organisational and sociological theories of rituals, as well as drawing empirically from a longitudinal qualitative interview study of a cohort of students in Swedish higher vocational education for work in digital data strategy, I explore how rituals are enacted in a vocational education and training setting and what these rituals mean to the aspirants who partake in them. The findings illustrate how rituals initiate, convert, and locate the participants in a team. These repeated encounters with rituals socialise, cultivate and build vocational faith amongst participants, despite the nascency and unstable nature of their education-to-work pathways. However, while rituals can serve as a catalyst to ignite processes of collective identification and vocational socialisation, they are not always successful. The paper discusses implications of faith-building in weak-form occupational pathways when the labour market is strong and conversely, when the economy is in recession. The text concludes by advocating the need for examining the power of educational institutions in shaping transitional experiences of participants in vocational education.
A review of cooperative rules and their associated algorithms for minimum-cost spanning tree problems
Authors: Bergantiños Gustavo , Vidal-Puga Juan 
Published: March 2021

AbstractMinimum-cost spanning tree problems are well-known problems in the operations research literature. Some agents, located at different geographical places, want a service provided by a common supplier. Agents will be served through costly connections. Some part of the literature has focused, mainly, in studying how to allocate the connection cost among the agents. We review the papers that have addressed the allocation problem using cooperative game theory. We also relate the rules defined through cooperative games with rules defined directly from the problem, either through algorithms for computing a minimal tree, either through a cone-wise decomposition.

Abstract
Background
Histone deacetylase (HDAC)-1, a Class-I HDAC family member, forms three types of complexes, the nucleosome remodeling deacetylase, Sin3, and CoREST complexes with the specific corepressor components chromodomain-helicase-DNA-binding protein 3 (Mi2/CHD-3), Sin3, and REST corepressor 1 (RCOR1), respectively, in humans.

Objective
To elucidate the functional relationships among the three transcriptional corepressors during embryogenesis.

Methods
The activities of HDA-1, LET-418, SIN-3, and SPR-1, the homologs of HDAC-1, Mi2, Sin3, and RCOR1 in Caenorhabditis elegans during embryogenesis were investigated through measurement of relative mRNA expression levels and embryonic lethality given either gene knockdown or deletion. Additionally, the terminal phenotypes of each knockdown and mutant embryo were observed using a differential-interference contrast microscope. Finally, the functional relationships among the three corepressors were examined through genetic interactions and transcriptome analyses.

Results
Here, we report that each of the corepressors LET-418, SIN-3, and SPR-1 are expressed and have essential roles in C. elegans embryonic development. Our terminal phenotype observations of single mutants further implied that LET-418, SIN-3, and SPR-1 play similar roles in promoting advancement to the middle and late embryonic stages. Combined analysis of genetic interactions and gene ontology of these corepressors indicate a prominent overlapping role among SIN-3, SPR-1, and LET-418 and between SIN-3 and SPR-1.

Conclusion
Our findings suggest that the class-I HDAC-1 corepressors LET-418, SIN-3, and SPR-1 may cooperatively regulate the expression levels of some genes during C. elegans embryogenesis or may have some similar roles but functioning independently within a specific cell.
Telemedicine in allergology: practical aspects

Published: March 2021

AbstractSince spring 2020, the wide-ranging contact restriction measures in the context of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic have also led to a reduction in physician–patient contacts in the ambulatory care setting. Telemedicine applications will increasingly provide a way to efficiently deliver patient care under infection control measures. In allergology, telemedical as well as digital applications can also significantly facilitate everyday clinical practice. However, the technical and legal hurdles associated with the implementation of digital strategies must be overcome for this to happen. The aim of this article is to provide an intuitive overview of the aspects to be considered in the implementation of telemedicine consultations and to highlight the current state of the framework as well as optimization possibilities and perspectives in allergology. If a structured use is guaranteed, digital and telemedical applications can improve patient care—also in allergology. There is potential to be exploited in many areas, from the remote collection of clinical history, and video consultations, to the discussion of diagnostic findings, disease monitoring, and therapy support. The use of telemedical applications, especially video consultations, has experienced a remarkable acceleration in the context of the coronavirus disease 2019 (COVID-19) pandemic. The present overview of the legal, technical and professional framework is intended to support the anchoring of digital and telemedical technologies in everyday allergology. However, in order to consolidate these in the future, an agreement is needed regarding professional standards of action as well as a remuneration structure that is permanently defined beyond the current pandemic.

AbstractThis paper studies the optimal low carbon production decision system with considered the constraints of carbon emission reduction policy for manufacturing enterprises producing two kinds of products in the free market. Firstly, The research proved the optimal production combination exists and it is unique under the carbon emissions limits, and next, the research analyzed the low-carbon production decision-making system in three situations, which are carbon emission trade decision, green technology input decision, and joint decision. The research results showed that carbon emission permits trade can increase more flexibility to manufacturing enterprises and increase their profits as well. However, the carbon emissions limits set by the government would have an important impact on the production decision system of manufacturing enterprises. Carbon emission permits trade and green technology investment can optimize and improve the production decision system of manufacturing enterprises to a certain extent. Meanwhile, the government's scientific and reasonable formulation of initial carbon quotas would mobilize the enthusiasm and initiative of manufacturing enterprises to participate in carbon emission reduction. The government should also guide and encourage enterprises to invest in and develop low-carbon emission reduction technologies through tax relief, so as to improve carbon emission reduction technologies and its innovations to reduce carbon dioxide emissions.

Published: March 2021

AbstractLearning the topology of a graph from available data is of great interest in many emerging applications. Some examples are social networks, internet of things networks (intelligent IoT and industrial IoT), biological connection networks, sensor networks and traffic network patterns. In this paper, a graph topology inference approach is proposed to learn the underlying graph structure from a given set of noisy multi-variate observations, which are modeled as graph signals generated from a Gaussian Markov Random Field (GMRF) process. A factor analysis model is applied to represent the graph signals in a latent space where the basis is related to the underlying graph structure. An optimal graph filter is also developed to recover the graph signals from noisy observations. In the final step, an optimization problem is proposed to learn the underlying graph topology from the recovered signals. Moreover, a fast algorithm employing the proximal point method has been proposed to solve the problem efficiently. Experimental results employing both synthetic and real data show the effectiveness of the proposed method in recovering the signals and inferring the underlying graph.

BACKGROUND:
The use of mesh in hernia repair has faced intense scrutiny, leading patients to become fearful of its use, despite its benefits in reducing hernia recurrence. We report a single institutional experience in performing hernia repair with mesh in terms of hernia-specific outcomes, mesh-related complications, and patient-reported quality of life.

STUDY DESIGN:
Patients who underwent abdominal wall hernia repair with mesh at a single institution were identified from a prospectively maintained quality database. Demographic, perioperative, and postoperative outcomes data were analyzed. Surgical Outcomes Measurements System (SOMS) and Carolinas Comfort Scale (CCS) surveys were administered pre- and postoperatively at 3 weeks, 6 months, 1, 2, and 5 years.

RESULTS:
Between 2010 and 2020, a total of 6,387 patients underwent abdominal hernia repair with mesh. Inguinal hernia repairs made up the majority (65%) of the operations. Rates of mesh infection varied by hernia type, with lower rates after umbilical (0.0%) and inguinal (0.4%) repair, and highest after incisional repair (1.3%). Similarly, mesh explantation rates were low after umbilical and inguinal repair (0.0% and 0.4%, respectively) and highest after incisional repair (3.0%). Scores on all SOMS domains were significantly improved from baseline (all p < 0.05). On CCS, 2.9%, 3.3%, and 4.4% of patients reported severe or disabling symptoms postoperatively at 1, 2, and 5 years, respectively.

CONCLUSIONS:
Rates of mesh-related complications vary by hernia type. A majority of patients report excellent long-term quality of life, although a relatively large percentage of patients experience severe or disabling symptoms at long-term follow-up.
Banach spaces for which the space of operators has 2𝔠closed ideals

AbstractWe formulate general conditions which imply that${\mathcal L}(X,Y)$, the space of operators from a Banach spaceXto a Banach spaceY, has$2^{{\mathfrak {c}}}$closed ideals, where${\mathfrak {c}}$is the cardinality of the continuum. These results are applied to classical sequence spaces and Tsirelson-type spaces. In particular, we prove that the cardinality of the set ofclosed ideals in${\mathcal L}\left (\ell _p\oplus \ell _q\right )$is exactly$2^{{\mathfrak {c}}}$for all$1<p<q<\infty $.

AbstractBackground:The dynamics of coronavirus disease 2019 (COVID-19) seroconversion of hospital employees are understudied. We measured the proportion of seroconverted employees and evaluated risk factors for seroconversion during the first pandemic wave.Methods:In this prospective cohort study, we recruited Geneva University Hospitals employees and sampled them 3 times, every 3 weeks from March 30 to June 12, 2020. We measured the proportion of seroconverted employees and determined prevalence ratios of risk factors for seroconversion using multivariate mixed-effects Poisson regression models.Results:Overall, 3,421 participants (29% of all employees) were included, with 92% follow-up. The proportion of seroconverted employees increased from 4.4% (95% confidence interval [CI], 3.7%–5.1%) at baseline to 8.5% [(95% CI, 7.6%–9.5%) at the last visit. The proportions of seroconverted employees working in COVID-19 geriatrics and rehabilitation (G&R) wards (32.3%) and non–COVID-19 G&R wards (12.3%) were higher compared to office workers (4.9%) at the last visit. Only nursing assistants had a significantly higher risk of seroconversion compared to office workers (11.7% vs 4.9%; P = .006). Significant risk factors for seroconversion included the use of public transportation (adjusted prevalence ratio, 1.59; 95% CI, 1.25–2.03), known community exposure to severe acute respiratory coronavirus virus 2 (2.80; 95% CI, 2.22–3.54), working in a ward with a nosocomial COVID outbreak (2.93; 95% CI, 2.27–3.79), and working in a COVID-19 G&R ward (3.47; 95% CI, 2.45–4.91) or a non–COVID-19 G&R ward (1.96; 95% CI, 1.46–2.63). We observed an association between reported use of respirators and lower risk of seroconversion (0.73; 95% CI, 0.55–0.96).Conclusion:Additional preventive measures should be implemented to protect employees in G&R wards. Randomized trials on the protective effect of respirators are urgently needed.

AbstractNew, distinctive, well-preserved and previously undescribed constituents of a Middle Ordovician (middle Darriwilian, Dw2) radiolarian assemblage from the Table Cove Formation in Newfoundland are described. Three-dimensional X-ray micro-computed tomography (μ-CT) facilitates detailed examination of key specimens revealing hitherto unknown details of the internal morphologies of key lower Paleozoic taxonomic groups, among which a lack of knowledge has previously impeded resolution of higher taxonomic rankings.Twenty-seven archaeospiculid and entactinarian taxa are described and illustrated including six new species: Westernbrookia polygonata n. sp., Neopalaeospiculum piccadilliensis n. sp., Ramuspiculum laxum n. sp. Spongentactinia nazarovi n. sp., Aspiculum irregulare n. sp., and Nyfrieslandia ramosissima n. sp. The investigation extends the known ranges of the species: Pararcheoentactinia reedae Won and Iams, 2002; Sphaeroentactinia robusta Won and Iams, 2015; Varispiculum ectospiculatum Won and Iams, 2015; and Svalbardospiculum multifurcatum (Won, Iams, and Reed, 2005), together with the genus Echidnina to the mid-Darriwilian.UUID: http://zoobank.org/74826b7b-bb86-45d5-ad23-e6e65e0706df.
The rise to dominance of lanternfishes (Teleostei: Myctophidae) in the oceanic ecosystems: a paleontological perspective
Authors: Schwarzhans Werner , Carnevale Giorgio 
Published: March 2021

AbstractLanternfishes currently represent one of the dominant groups of mesopelagic fishes in terms of abundance, biomass, and diversity. Their otolith record dominates pelagic sediments below 200 m in dredges, especially during the entire Neogene. Here we provide an analysis of their diversity and rise to dominance primarily based on their otolith record. The earliest unambiguous fossil myctophids are known based on otoliths from the late Paleocene and early Eocene. During their early evolutionary history, myctophids were likely not adapted to a high oceanic lifestyle but occurred over shelf and upper-slope regions, where they were locally abundant during the middle Eocene. A distinct upscaling in otolith size is observed in the early Oligocene, which also marks their earliest occurrence in bathyal sediments. We interpret this transition to be related to the change from a halothermal deep-ocean circulation to a thermohaline regime and the associated cooling of the deep ocean and rearrangement of nutrient and silica supply. The early Oligocene myctophid size acme shows a remarkable congruence with diatom abundance, the main food resource for the zooplankton and thus for myctophids and whales. The warmer late Oligocene to early middle Miocene period was characterized by an increase in disparity of myctophids but with a reduction in their otolith sizes. A second and persisting secular pulse in myctophid diversity (particularly within the genus Diaphus) and increase in size begins with the “biogenic bloom” in the late Miocene, paralleled with diatom abundance and mysticete gigantism.
‘Here be revisionary metaphysics!’ A critique of a concern about process philosophy
Authors: Giladi Paul 
Published: March 2021

ABSTRACTIn this paper, I argue that John Dupré and Daniel Nicholson's ‘process manifesto’ is ironically more sympathetic to descriptive metaphysics than to revisionary metaphysics. Focusing on their argument that any process philosophy automatically slides into Whiteheadian obscurantism if it does not just rest content with revealing the problematic features of ordinary language, I argue that their position occludes a logical space, one in which revisionary metaphysics is articulated without any Whiteheadian obscurantism and involves no dereliction of critical/revisionary orientation. I argue that key features of the respective critical social ontologies of Judith Butler and Talia Mae Bettcher occupy such a logical space.
THE YONEDA EXT AND ARBITRARY COPRODUCTS IN ABELIAN CATEGORIES
Authors: ARGUDÍN-MONROY ALEJANDRO 
Published: March 2021

AbstractThere are well-known identities involving the Ext bifunctor, coproducts, and products in AB4 abelian categories with enough projectives. Namely, for every such category \[\mathcal{A}\], given an object X and a set of objects \[{\{ {{\text{A}}_{\text{i}}}\} _{{\text{i}} \in {\text{I}}}}\], an isomorphism \[Ext_\mathcal{A}^{\text{n}}({ \oplus _{{\text{i}} \in {\text{I}}}}{{\text{A}}_{\text{i}}},{\text{X}}) \cong \prod\nolimits_{{\text{i}} \in {\text{I}}} {Ext_\mathcal{A}^{\text{n}}({{\text{A}}_{\text{i}}},{\text{X}})} \] can be built, where \[Ex{t^{\text{n}}}\] is the nth derived functor of the Hom functor. The goal of this paper is to show a similar isomorphism for the nth Yoneda Ext, which is a functor equivalent to \[Ex{t^{\text{n}}}\] that can be defined in more general contexts. The desired isomorphism is constructed explicitly by using colimits in AB4 abelian categories with not necessarily enough projectives nor injectives, extending a result by Colpi and Fuller in [8]. Furthermore, the isomorphisms constructed are used to characterize AB4 categories. A dual result is also stated.
Helminths of the mallardAnas platyrhynchosLinnaeus, 1758 from Austria, with emphasis on the morphological variability ofPolymorphus minutusGoeze, 1782

Published: March 2021

AbstractThe mallardAnas platyrhynchosis the most abundant water bird species in Austria, but there is no record of its helminth community. Therefore, this work aimed to close that gap by recording and analysing the parasite community of a large number of birds from Austria for the first time. A total of 60 specimens shot by hunters in autumn were examined for intestinal parasites. The following taxa were recovered (prevalence given in parentheses): Cestoda:Diorchissp. (31.7%) andFimbriarioides intermedia(1.7%); Acanthocephala:Filicollis anatis(5%),Polymorphus minutus(30%) and one cystacanth unidentified (1.7%); Trematoda:Apatemon gracilis(3.3%),Echinostoma grandis(6.7%),Echinostoma revolutum(6.7%) andNotocotylus attenuatus(23.3%); Nematoda:Porrocaecum crassum(1.7%) and one not identified (1.7%). The frequency distribution of parasites showed a typical pattern in which 39 birds (65%) were either not parasitized or were harbouring up to five worms, whereas more intense infestations occurred in a lesser number of hosts. Compared to other studies from central and eastern Europe, an extremely depauperate helminth community, particularly of the cestodes and nematodes, was found.Polymorphus minutuswas observed as having highly variable morphology and, therefore, molecular genetic characterization by DNA barcoding was carried out. Species identification was confirmed by comparing data with the reference cytochromecoxidase subunit 1 gene sequence fromP.minutusavailable in GenBank.
Market-Oriented Policies on Care for Older People in Urban China: Examining the Experiment-Based Policy Implementation Process
Authors: ZHANG WENJING 
Published: March 2021

AbstractThe rapidly ageing population and increasing care needs provide the rationale for care systems progressively shaped by a growing market in a global context. In China the approach to policy making, which has been largely experimental, has involved market-oriented reforms since the 1980s. While marketisation processes have been well studied in various European care systems, very little is known about their implementation in the Chinese context. Based on qualitative interviews with local government officials and care providers in Shanghai, this article discusses the Chinese policy process in the field of care for older people and the barriers to effective implementation. It investigates the experiment-based marketisation policy process, the power hierarchy and the lines of accountability of the state in the care field. Multi-layered barriers are identified in the market-oriented policy process. These include (1) inherent bureaucratic obstacles at practice level: reluctance to exercise discretionary power, administrative inefficiency, incoherence of care schemes and poor inter-department communication; and (2) complexities and failures at policy-making level: the infeasibility of policies, underestimation of operational capacity and inadequate involvement of practice knowledge. These findings have implications for balancing the efficiency, effectiveness and sustainability of care policies in an era of public service austerity.
