AbstractThis study hypothesized that urea fertilization could optimize animal performance in an agroforestry system. This study evaluated how increasing rates of N fertilization (0, 100, 200, and 400 kg N ha−1 year−1) using urea (CH4N2O) affected forage mass, nutritive value, and beef cattle (Bos indicus) performance in an agroforestry system with Massai grass (Megathyrsus maximus Jacq. cv. Massai) and legume tree (Mimosa caesalpiniifolia Benth.), in the humid tropic region of Brazil, over 2‐year period. The experiment was carried out in a randomized complete block design with four treatments (N fertilizer rates) and three replications. Forage mass was positive and linearly affected by N fertilization (p = .0236, R2 = 0.92), ranging from 1297 to 1583 kg DM ha−1 under 0 and 400 kg N ha−1 year−1, respectively. There was greater average forage mass during the rainy period (1826 kg ha−1) (p < .05). Crude protein in green forage mass increased linearly (p = .0041, R2 = 0.91) in function of the N applied. Cattle average daily gain showed a positive quadratic response to the rates of N applied (p = .0298, R2 = 0.97), ranging from 0.46 kg to 0.68 kg animal day−1; and the gain per area increased linearly from 1.84 to 2.68 kg LW ha−1 day−1 (p = .0640, R2 = 0.96). The findings indicate that applying 200 kg N ha−1 year−1, split‐applied during the rainy season, would yield acceptable outcomes in terms of forage mass, nutritive value, and animal performance for this type of agroforestry system.

Published: June 2024

AbstractPorewater in soil vadose zones is an integrator of the fundamental processes governing the transport and partitioning of per and poly‐fluoroalkyl substances (PFAS) as they move from source zones to groundwater. Suction lysimeters are being advanced as a method to provide reliable and representative PFAS porewater samples, to inform PFAS leaching and for monitoring remedial approaches. We report outcomes of lysimeter investigations across 3 sites and 18 lysimeters within fine‐textured soil profiles. Soil cores were recovered from the same locations, and PFAS concentrations in soils and lysimeter porewater were compared and compared with prior laboratory investigations. Variable concentration distributions with depth of PFAS in soils were found with a maximum sum of PFAS of ~56 mg/kg dominated by perfluorooctane sulfonic acid (PFOS). The maximum sum of PFAS in porewater was 13.5 mg/L. Comparison across all collocated soil and porewater concentrations did not provide consistent trends. PFAS mass fractions within lysimeter porewater samples were much higher for most PFAS than mass fractions determined from laboratory investigations, but the fraction was lower for PFOS. The results indicate preferential recovery of individual shorter chain PFAS via leaching at lower liquid: soil ratios such as those experienced under suction during recovery of porewater by lysimeters. Suggestions are offered to advance the use of suction lysimeters in promoting porewater PFAS concentrations as an alternative for regulatory compliance, and in closing the gap between field and laboratory approaches. There is merit in using lysimeters at PFAS field sites with improvements and considerations embraced.
LANGUAGE—HISTORY—PRESENCE
Authors: ALONZI LUIGI 
Published: June 2024

ABSTRACTThis article deals with the use of language in historiography and with this usage's implications for the conception of history and the historiographical operation/practice. Whereas theorists of “presence” believe that “presence” and “reality” can be grasped in spoken language and written texts, thus generally considering them as a medium that enables access to a “reality” that lies beyond texts and language, I argue that language and texts should themselves be considered as a “reality.” We need to distinguish the process of “presentification” performed by words from the presence of language as a lexical and physical reality; though the two aspects are strictly connected, the presence of language needs to be emphasized as a lexical‐semantic system and as a thing in the world. In this article, I consider language as a “living witness” of the narrated events; it is a presence in the moment that events occurred and a presence that is still present. We should think of language as we think of the material world around us—that is, as a transformed landscape that contains present and absent pasts. Historians of “presence” consider the meanings associated with language as a major obstacle obstructing the understanding of history in a new unmediated way; to some extent, this article is an attempt to hold meaning and presence together.

AbstractThis study evaluates Algerian kaolin (Djebel Debbagh (DD1) and Tamazart (KT2)) as potential substitutes for commercial kaolin (Lab) in the production of mullite‐based ceramics. Three compositions were prepared by incorporating the appropriate percentage of alumina to each calcined kaolin to achieve stoichiometric mullite precursors. The phase evolution of individual kaolin powders, as well as their mixtures with alumina, depends strongly on the calcination temperature and kaolin impurities. The differential scanning calorimetry combined with thermogravimetric analysis (TGA) showed lower secondary mullite formation temperature for the KT2‐based mixture. However, X‐ray diffraction revealed a complete mullitization in DD1 mixture. The K2O hindered cristobalite formation and reduced secondary mullite formation rate. Microstructure analysis showed lath‐shaped primary mullite and equi‐axed secondary mullite particles. After sintering at 1600°C, The KT2‐based sample (M3) exhibited higher density (3.013 g/cm3) and hardness (9.9 GPa), whereas the DD2‐based sample (M2) showed moderate densification (2.91 g/cm3) and higher flexural strength (159.42 MPa). Impurities (mainly Fe2O3, and K2O) promoted liquid phase sintering, resulting in greater densification in M3, whereas M2 showed more homogeneous microstructure, refined grains, and lower glassy phase content, contributing to enhanced strength.
Communication in organizations: An overview and provocations

Published: June 2024

AbstractThe role that communication plays in social organization and processes of organizing has received considerable scholarly attention from multiple disciplines over several decades. This paper provides a review of the diverse literature that has sought to contribute to the understanding of communication and its implication for management and organization studies. An analysis of the SCOPUS database for the period 1980–2022 enabled us to cluster reference material and identify five perspectives which emerge from a review of the literature: communication as transfer, discourse, conversation (analysis), narrative, and Communicative Constitution of Organizations. These categories are not intended to be exhaustive, but they do provide a useful critical heuristic for navigating a field of study that might otherwise appear overwhelming. To map the terrain's theoretical underpinnings, our study also adopted a problematizing approach to the review which revealed various conspicuous conceptual and empirical absences at a ‘field level’ which merit further attention. The paper offers provocations and suggestions that we expect will inform future studies of organizational communication. Possibilities for developing the field include paying attention to: (a) paralinguistic dimensions of communication; (b) communication in relation to actual work practices; (c) monologic communication and (d) organizational communication in non‐Western contexts.

SummaryBackgroundAnti‐obesity medications (AOMs) are promising lifestyle modification (LSM) adjuncts for obesity treatment, and phentermine is commonly prescribed in paediatric weight management clinics. Determining ‘real‐world’ AOM effectiveness and characteristics predicting response is important.ObjectivesWe sought to describe phentermine plus LSM effectiveness and identify baseline characteristics predicting response.MethodsThis was a retrospective cohort study among youth seen in a US academic‐based weight management clinic from 2012 to 2020. Baseline characteristics (e.g., body mass index (BMI), liver transaminases, eating‐related behaviours) and outcomes (%BMI of 95th percentile (%BMIp95), BMI, %BMI change, weight) were determined through electronic health records and intake surveys.ResultsAmong 91 youth prescribed phentermine plus LSM over 8 years (mean %BMIp95 150%), %BMIp95 was statistically significantly reduced at 1.5, 3, 6 and 12 months (peak reduction 10.9 percentage points at 6 months; p < 0.001). Considering multiple comparisons, the presence of baseline elevated alanine aminotransferase was associated with statistically significant smaller 1.5‐month %BMIp95 reductions (p = 0.001) and higher food responsiveness with smaller 3‐ (p = 0.001) and 6‐month (p < 0.001) reductions.ConclusionsPhentermine plus LSM reduced %BMIp95 among youth in a weight management clinic, and baseline characteristics may help determine those more or less likely to respond. Prospective studies are needed to further characterize effectiveness and confirm response predictors.
“You are too expensive, you need to work faster!”: Ukrainian agricultural workers navigating precarities in Denmark
Authors: Horton Elena , Whyte Zachary 
Published: June 2024

AbstractUkrainian migration to Denmark has been structured by national fast‐track programmes, predominantly funnelling Ukrainians towards low‐skilled and precarious jobs in Danish livestock production. However, since the recent Russian invasion, the introduction of Law L145 has entitled Ukrainians in Denmark to similar employment rights as the European Union citizens through an SL1 visa. While this opens up previously inaccessible areas of the Danish labour market, it also makes Ukrainians subject to the same restrictive legislation as other refugees and puts a hard end date to their visas, making their future status uncertain. Drawing on in‐depth interviews with nine Ukrainian agricultural workers living in Denmark at the time of the invasion, this article explores their attempts to navigate precarities of work, gender and legal status in Denmark. Precarities of work sprang from differences between agricultural sectors, as year‐round work with livestock involved a dependence on farmers, where workers accepted exploitative conditions in order to maintain their residence and work permits. Precarities of gender were reflected in the way women were made dependent on their partner through an “accompanying family members” visa, which shaped family lives and became problematic in the case of separations. Precarities of legal status were created by frequent legislative changes that made legal status uncertain and destabilized the long‐term investments of Ukrainians planning to stay in Denmark. While the SL1 offered a way out of some of the precarities experienced by agricultural workers, it did so at the cost of added complications and continuing uncertainty, pushing people from one kind of precarity to another.

ABSTRACTBackgroundAcute respiratory infections (ARIs) are a major healthcare issue in children. The SARS‐CoV‐2 pandemic changed the epidemiology of ARIs; the aims of this study are to characterize the epidemiological trend of ARI emergency hospitalizations and virology results and to estimate the association of ARI emergency hospitalizations with respiratory viruses from January 2018 to June 2023.MethodsThis study was carried out in an Italian tertiary care children's hospital (Bambino Gesù Children's Hospital). The demographic and clinical information of children who accessed the Emergency Department (ED) with ARI and were hospitalized were retrospectively extracted from the electronic health records. Multivariate linear regression model was used to compare the number of ARI hospital admissions with the reported temporal trends in viruses diagnosed from respiratory samples throughout the same time period.ResultsDuring the study period, there were 92,140 ED visits and 10,541 hospitalizations due to ARIs, reflecting an admission rate of 11.4%. The highest proportion of hospitalizations occurred in infants ≤ 1 year of age (n = 4840, 45.9% of total admissions), with a hospitalization rate of 22.6%. Emergency hospitalizations aligned closely with the predictions made by the multivariate regression model; peaks in hospitalizations reflected Respiratory Syncytial Virus (RSV) circulation.ConclusionsARI hospital urgent admissions are a relevant component of ARI disease burden in children. RSV prevention and control are crucial to limit the risk of urgent hospitalizations due to ARIs.
Efficacity of hyperbaric oxygen therapy for necrotizing fasciitis in the maxillofacial region: The review of the literature

Published: June 2024

AbstractNecrotizing fasciitis (NF) is a rare, dangerous, potentially fatal infectious disease of soft tissue. The treatment consists of antibiotic therapy, surgical debridement and subsequent reconstruction. Hyperbaric oxygen (HBO) therapy has been applied in NF patients recently, so our aim was to gather the findings and outcomes for HBO therapy. A PubMed and Google Scholar literature search was conducted regarding the effect of HBO therapy in patients with NF following key words: ‘necrotizing fasciitis’ AND ‘maxillofacial region’ OR ‘head and neck’ AND ‘hyperbaric oxygen’ OR ‘HBO’. A total of 3333 studies have been identified, of which only 16 articles met the inclusion criteria of this review. A conclusion was made, that aggressive combinations of antibiotics and surgical debridement followed by incorporation of HBO therapy, as an adjuvant treatment, in patients with NF and in company by immunoglobulin therapy are showing promising results. In addition, multi‐centric studies should be in consideration for further research.

AbstractAimTo synthesize and assess the effectiveness of different care delivery models in a hospital setting, taking into account patient‐ and nurse‐related outcomes.DesignA systematic review with narrative synthesis in which a comparison was made between different care delivery models.MethodsThe search string consisted of four clusters: ‘nursing’, ‘care delivery models’, ‘hospital setting’ and ‘quantitative research designs’. Four electronic databases were searched from the inception of the databases to January 2023: Medline, Embase, CINAHL and Web of Science.ResultsIn total, 19 studies were included in the systematic review. The most commonly compared care delivery models were functional nursing to primary nursing (n = 6), patient allocation to team nursing (n = 4), team nursing to primary nursing (n = 3) and functional nursing to modular nursing (n = 3). Only one randomized crossover trial was found, other included studies were pretest–posttest designs or quasi‐experimental designs. The implementation of a nursing care delivery model was the study intervention. The following aspects of the intervention were not reported or inadequately described by the majority of the authors; tailoring of an intervention, modifications to an intervention and the adherence or fidelity to the intervention. Job satisfaction and quality of nursing care were the most commonly reported nursing outcomes, while patient satisfaction was the most commonly reported patient outcome. Due to a high heterogeneity in outcome measures between the studies, a meta‐analysis of the included studies was not possible. All included studies had a high risk of overall bias.ConclusionThis systematic review found mixed evidence, inconsistent reporting of certain elements of the interventions, high heterogeneity in outcome measures and low methodological quality. Although this systematic review could not answer which nursing care delivery model is the most effective or most promising, other important findings from this review may inform future research.Impact

There are differences in care delivery model descriptions and a lack of agreement on the strengths and weaknesses of the care delivery models.

No clear‐cut answer can be given about the effect of different care delivery models in a hospital setting on patient‐ and nurse‐related outcomes.

Job satisfaction and quality of nursing care were the most commonly reported nursing outcomes, while patient satisfaction was the most commonly reported patient outcome.

This review can support the development of future care delivery redesign strategies.

The EU Commission During the Covid‐19 Crisis: Attempts at Self‐Empowerment, or Not?
Authors: Brandsma Gijs Jan , Blom‐Hansen Jens 
Published: June 2024

AbstractWe argue that the European Commission, like national governments, is likely to have used the Covid‐19 crisis as an opportunity to bolster its own powers. We focus on the Commission's attempts to insert into legal proposals provisions to adopt delegated or implementing acts, as this is the only possible way to gain lasting rule‐making powers. We analyse all the Commission's legal proposals for an equal time span before and after the start of the Covid‐19 crisis and study whether the number of proposed delegation provisions has changed after the onset of the crisis. The analysis, to our surprise, does not show any clear evidence of a self‐empowerment strategy. In the conclusion, we discuss likely explanations for this non‐finding.
Recruitment of European sea bass (Dicentrarchus labrax) in northerly UK estuaries indicates a mismatch between spawning and fisheries closure periods

Published: June 2024

AbstractEuropean sea bass (Dicentrarchus labrax) is a species of high commercial and recreational value, but it exhibits highly variable recruitment rates and has been subject to recent declines. Emergency management measures put in place to protect spawning stocks include the annual closure of commercial and recreational fisheries over a 2‐month, February–March, window. Whether this protection measure is having the desired outcome for this data‐poor species remains unclear. Otolith microstructural analyses (counts and widths of daily growth rings and check marks indicative of settlement) were used to estimate (1) spawn timing, (2) pelagic larval duration and settlement timing, (3) growth rate and condition, and (4) the otolith‐fish size relationship for juvenile European sea bass caught from two estuaries in Wales (Dwyryd, Y Foryd), located at the northern edge of the species range. We observed a significant mismatch between the timing of fisheries closures and the spawning, with 99.2% of recruits having been spawned after the fishery had reopened (back‐calculated median spawn date = May 5 ± 17 days SD), suggesting that the closure may be too early to adequately protect this population. Further, we present the first empirically derived estimates of pelagic larval duration for sea bass recruits settling in UK habitats, which showed a strong negative relationship with spawn date. Finally, we found significant differences in fish condition between the two estuaries, suggesting local variation in habitat quality. The results suggest that the timing of current fisheries closures may not be adequately protecting the spawners supplying these northernmost estuaries, which are likely to become increasingly important as sea bass distributions shift northward in our climate future.

Published: June 2024

AbstractBackgroundIndividuals with spinal cord injuries (SCIs) are at an increased risk of poor oral health compared to the general population. However, little is known about the related barriers and facilitators experienced by these individuals within the hospital setting.ObjectivesUnderstand the oral health knowledge, attitudes and practices of people with SCIs, barriers and facilitators to managing their oral health, and recommendations to improve oral care at acute/rehabilitation hospital settings.MethodsSemi‐structured interviews were conducted with 11 participants, from a major metropolitan hospital in Sydney, Australia. The interviews were thematically analysed.ResultsThree themes were constructed. Participants believed that the onus was on them to manage their oral health. Individuals also had limited knowledge of its importance to general health, and placed a lower priority on oral health compared to other aspects of health. All participants identified a combination of factors, such as cost, time, resources and prior negative experiences, that contributed to the neglect of their oral care. Participants also discussed the need of support from the multidisciplinary team and family/carers to facilitate oral care and identified various appropriate oral health education formats.ConclusionThis study highlighted some areas where oral health knowledge among people with SCIs could be improved. It also identified the need for oral health training for the multidisciplinary team, as well as carers, to better integrate oral care during rehabilitation in the hospital. The development of oral health interventions would need to utilise a co‐design approach to best support clients and their carers to facilitate oral care self‐management.
