Interactions of nitrogen and phosphorus in plant nutrition - Analysis of a 60-years old field experiment
Authors: Spohn Marie 
Published: September 2024

Abstract
Background and aims
The aims are to determine to which extent different plant species increase nitrogen (N) acquisition in response to phosphorus (P) addition and P acquisition in response to N addition as well as to analyze resulting nutrient limitations.

Methods
The field experiment is replicated at ten sites in Sweden and comprises three fertilization regimes (low, medium, and high) each consisting of a control and a N, P, and NP treatment. Yields as well as N and P contents of the yields of four species (winter wheat, spring barley, oat, and sugar beet) were analyzed over 60 years.

Results
The relative increase in yield P in response to N fertilization was larger than the relative increase in yield N in response to P fertilization for three species. Synergistic NP co-limitation was observed for all species at some sites. The synergistic growth effect in response to NP addition occurred at more sites at high than at low fertilization. At one nutrient-poor site, all species in all fertilization regimes were (synergistically) NP co-limited. Sugar beet was (synergistically) NP co-limited at all sites in all fertilization regimes.

Conclusion
Species differed in nutrient acquisition, but most species used added N more effectively to acquire P than they used added P to acquire N. Synergistic NP co-limitation was observed for all plant species at some sites, and it increased with fertilization rate, which is likely due to the limits to which plants can use N to acquire P and P to acquire N.

Published: September 2024

Abstract
Obesity is a complex, multifactorial, chronic disease that acts as a gateway to a range of other diseases. Evidence from recent studies suggests that changes in oxygen availability in the microenvironment of metabolic organs may exert an important role in the development of obesity-related cardiometabolic complications. In this review, we will first discuss results from observational and controlled laboratory studies that examined the relationship between reduced oxygen availability and obesity-related metabolic derangements. Next, the effects of alterations in oxygen partial pressure (pO2) in the adipose tissue, skeletal muscle and the liver microenvironment on physiological processes in these key metabolic organs will be addressed, and how this might relate to cardiometabolic complications. Since many obesity-related chronic diseases, including type 2 diabetes mellitus, cardiovascular diseases, chronic kidney disease, chronic obstructive pulmonary disease and obstructive sleep apnea, are characterized by changes in pO2 in the tissue microenvironment, a better understanding of the metabolic impact of altered tissue oxygenation can provide valuable insights into the complex interplay between environmental and biological factors involved in the pathophysiology of metabolic impairments. This may ultimately contribute to the development of novel strategies to prevent and treat obesity-related cardiometabolic diseases.
How to Assess Livelihoods? Critical Reflections on the Use of Common Indicators to Capture Socioeconomic Outcomes for Ecological Restoration workers in South Africa
Authors: Pasgaard M. , Fold N. 
Published: September 2024

AbstractSocial outcomes from conservation and development activities on a local scale are often assessed using five livelihood assets—Natural, Physical, Human, Financial and Social—and their associated indicators. These indicators, and the variables used to measure them, are typically based on ‘common practice’ with limited attention being paid to the use of alternative indicators. In this article, we present a typical survey of socioeconomic benefits for ecological restoration workers in South Africa, and ask whether the common livelihood indicators used are adequate and sufficient, or whether any relevant indicators are missing. Results from the livelihood survey show the value of income, food and education as strong indicators of financial and human assets, and the importance of open-ended questions in eliciting details of workers’ perceived changes in their livelihoods. However, by complementing the survey results with qualitative data from semi-structured interviews and stakeholder workshops, we show how unconventional livelihood indicators and aspects provide a deeper understanding of changes in livelihoods that are tied to restoration projects. We guide scholars and practitioners to advance their process of selecting livelihood indicators, in particular to include three additional types of indicators: intangible indicators to assess life quality; relative indicators reaching across spatial and temporal scales to capture community outcomes and livelihood resilience; and, political indicators to uncover causal relationships.
Exploring preservice teachers’ social domination orientation and prejudice toward Syrian refugees: the mediation of empathy
Authors: Kirisci-Sarikaya Aylin , Guner Halim 
Published: September 2024

AbstractWith the global increase in refugees, understanding and improving the educational experiences of refugees has received more attention in academic research. This study aims to investigate the perspective of preservice teachers (PSTs) towards Syrian refugees, who are one of the largest groups of refugees in Turkey. The study explores the relationship between PSTs’ empathy, their social dominance orientation (SDO), and prejudice against Syrian refugees. The aim is to understand how PSTs’ perspectives on refugees can help prevent discrimination in education and develop targeted interventions and educational strategies. The study analyzed data from 726 PSTs using structural equation modelling. The findings show that there is a positive correlation between SDO and prejudice, and empathy partially mediates this relationship. Moreover, socioeconomic status and ethnicity significantly predict prejudice against refugees. The results are discussed in relation to the understanding of the bases and relations of prejudice, SDO, and empathy. The study suggests some practical implications for those working with PSTs and policymakers.
Teachers’ daily positive and negative affect and their relationship with teachers’ emotion regulation strategies and daily work engagement – results of a diary study among team teachers
Authors: Muehlbacher Franziska , Mejeh Mathias , Keller Melanie M. , Hagenauer Gerda 
Published: September 2024

AbstractTeam teaching as a close form of teacher collaboration entails frequent interactions between the team-teaching partners in the classroom. During these interactions, the team teachers experience a variety of positive and negative emotions, triggered by their team partner. The teachers may express or suppress these emotions, depending on their habitual use of these emotion regulation strategies. In turn, the teachers’ daily emotions may be related to an important facet of teacher well-being, namely their daily work engagement. This study aims to investigate the related factors (habitual emotion regulation, daily work engagement) of team teachers’ daily positive and negative emotions triggered by the team partner in the classroom. Forty-seven Austrian team teachers working in secondary education completed a daily diary study, consisting of 15 diary entries, measuring their habitual emotion expression and suppression strategies, their daily positive and negative affect and daily work engagement. Multilevel regression analyses were conducted. Results show that positive and negative affect and work engagement vary substantially within and between team teachers. Random-intercept fixed-slope multilevel models indicate that the habitual use of authentic display of positive emotions is associated with daily positive affect, and teachers’ daily positive and negative affect significantly relate to their daily work engagement both on the within- and between-person level. This study underscores the important role that team teachers’ emotional experiences play regarding their work engagement. We draw theoretical and practical implications for the role of emotions during team-teaching practices.
Staying on-shell: manifest properties and reformulations in particle physics
Authors: Hunt Josh 
Published: September 2024

AbstractThe empirical success of particle physics rests largely on an approximation method: perturbation theory. Yet even within perturbative quantum field theory, there are a variety of different formulations. This variety teaches us that reformulating approximation methods can provide a tremendous source of progress in science. Along with enabling the solution of otherwise intractable problems, reformulations clarify what we need to know to obtain solutions, which can in turn make previously hidden properties manifest. To develop these lessons, I compare and contrast three compatible formulations of perturbative QFT: (i) elementary perturbation theory, (ii) the method of Feynman diagrams, and (iii) a recent reformulation known as on-shell recursion. I propose and defend a novel account of what it means to ‘make a property manifest,’ based on the inferences that a formulation warrants.
Bidding behaviour in experimental auctions under risk and uncertainty

Published: September 2024

AbstractThis paper explores bidding behaviour under risk and uncertainty using the Becker-DeGroot-Marschak mechanism (BDM) and second price auction (SPA). It investigates whether values elicited via the two mechanisms are consistent and whether bidding behaviour can be influenced by differences in the number and type of sources of risk and uncertainty that people face when exposed to the two mechanisms. In our experiment, subjects are exposed to non-monetary lotteries where they bid for a high-quality seafood product, but there is a chance (known or unknown) that they receive a lower quality seafood product instead. Results indicate that bidding behaviour can be influenced by the number and type of sources of risk and uncertainty that subjects face and subjects’ bidding behaviour is only consistent with standard theories of decision making under risk and uncertainty when they bid on a risky product in the SPA. Despite this, BDM and SPA elicit equal values under risk and uncertainty in this study.

Published: September 2024

AbstractE-textiles provide an interesting field of research as they “blend traditional craft with modern science” (Peppler, 2016) and help learners “broaden their own perceptions of computing” (Searle et al., 2016). Despite the promising findings by primarily long-term interventions structured around e-textiles, educational curriculum reform has been slow to materialize. Educators who embrace a STEAM philosophy are more likely to endorse short workshops, integrating them in existing courses or initiatives; this could serve as a steppingstone for longer interventions and bottom-up curriculum reform. This study examines whether shorter e-textile workshops (lasting four hours) can result in significant gains in understanding. We present an investigation of e-textiles with 22 young children who have no prior experience with e-textiles or working with microprocessors. We present details of our learning design, as well as findings related to circuitry knowledge and computational making skills. We find that the children advanced their circuitry knowledge and practice a range of computational making skills. We further document a series of emerging challenges, including the children’s unwillingness to engage or lack of adeptness with software, a tension between aesthetics and construction, creativity limited by samples of previous e-textile projects, and the difficulty in grasping the materiality of e-textiles. We propose that some direct instruction and facilitation is not incompatible with the making ethos; the approach can help address these challenges, allowing young children to benefit from their participation in short-duration e-textile workshops.

AbstractChronic insufficient and poor-quality sleep are linked to hypertension, diabetes, depression, heart attack, and stroke. While studies on substance use and sleep typically focus on people in or entering treatment, there is a lack of research on sleep health among community-recruited people who inject drugs (PWID). To address this literature gap, we examined factors associated with insufficient and poor-quality sleep among community-recruited PWID. We recruited and interviewed 472 active opioid-using PWID (injected within the last 30 days) in Los Angeles, CA and Denver, CO between 2021 and 2022. Participants completed computer-assisted interviews covering demographics, subsistence measures, drug use patterns, injection-related behaviors, health risks, and sleep duration and quality in the last 3 months. Descriptive statistics were used to analyze all variables for subjects with complete responses to sleep items (n = 464). Bivariate analyses determined factors associated with sleep measures using chi-square and t-tests. Collinear variables were removed, and binomial linear multivariable regression calculated risk ratios (RR) for insufficient and poor-quality sleep in the last 3 months. Participants exhibited low sleep duration (mean = 4.99, standard deviation (SD) = 2.70), with 76% reporting insufficient sleep and 62% poor-quality sleep. Bivariate analyses associated both sleep measures with drug use, high subsistence scores, violent victimization, and poor health outcomes. Multivariable analyses showed a high subsistence score predicting insufficient (RR = 1.31) and poor-quality sleep (RR = 1.69) compared to low subsistence. Poor sleep health is common among structurally vulnerable community-recruited PWID, as measured by subsistence index associated with adverse sleep outcomes. Further research on structural interventions to address sleep and subsequent health outcomes among PWID is imperative.

Zusammenfassung
Menschen mit intellektuellen Beeinträchtigungen (IB) sind in ihrem Alltag mit einer Vielzahl gesundheitsbezogener Barrieren konfrontiert, die ihnen eine gleichberechtigte Teilhabe erschweren. Obwohl Menschen mit IB, wie alle anderen auch, psychisch gesund und psychisch erkrankt sein können, ist bisher unklar, was psychische Gesundheit in dieser Personengruppe ausmacht. Dieser Artikel der Zeitschrift für Psychodrama und Soziometrie gibt Einblicke in ein partizipatives Forschungsprojekt an der Universität Wien, das die Annäherung an ein gemeinsames Verständnis psychischer Gesundheit bei Menschen mit IB zum Ziel hat. Dabei werden die Perspektiven von Menschen mit IB als Expert*innen in eigener Sache und die Sichtweisen von Expert*innen aus dem Bereich psychische Gesundheit bei Menschen mit IB gleichermaßen berücksichtigt.

AbstractThis work models the microstructural evolution as a function of position in laser-wire deposited Ti–6Al–4V parts using a classical multi-component JMAK nucleation and growth model with additive isothermal time-steps. Model predictions are compared to experimental observations. The model can be used to interpret nucleation and growth kinetics of various characteristic features of the microstructure that are inaccessible by experiments. It explains the presence of “layer bands” at specific locations unrelated to the weld bead structure. The last re-heating (of multiple thermal cycles) of a solidified layer, and where it peaks, plays a key role in increasing the nucleation density at specific locations, resulting in full $$\alpha $$

Abstract
To investigate the potential contribution of chest wall muscle area (CWMA) to the ventilatory efficiency and exercise capacity in patients with Systemic Sclerosis (SSc) without interstitial lung disease (ILD). Forty-four consecutive SSc patients [F = 37, median age 53.5 years (IQR 43.5–58)] were examined using chest high-resolution computed tomography (HRCT), pulmonary function tests and cardiopulmonary exercise testing (CPET). The CWMA was evaluated at the level of the ninth thoracic vertebra on CT images by two independent evaluators blinded to the patient information. CPET parameters analyzed were maximum oxygen uptake (VO2 max) and VO2 at anaerobic threshold (VO2@AT); minute ventilation (VE); maximum tidal volume (VT). A statistically significant positive correlation was found between CWMA and maximum workload (r = 0.470, p < 0.01), VO2 max ml/min (r = 0.380, p < 0.01), VO2@AT (r = 0.343, p < 0.05), VE (r = 0.308, p < 0.05), VT (r = 0.410, p < 0.01) and VO2/heart rate (r = 0.399, p < 0.01). In multiple regression analysis, VO2 max (ml/min) was significantly associated with CWMA [β coefficient = 5.226 (95% CI 2.824, 7.628); p < 0.001], diffusing capacity for carbon monoxide (DLco) [β coefficient = 6.749 (95% CI 1.460, 12.039); p < 0.05] and body mass index (BMI) [β coefficient = 41.481 (95% CI 8.802, 74.161); p < 0.05]. In multiple regression analysis, maximum workload was significantly associated with CWMA [β coefficient = 0.490 (95% CI 0.289, 0.691); p < 0.001], DLco [β coefficient = 0.645 (95% CI 0.202, 1.088); p < 0.01] and BMI [β coefficient = 3.747 (95% CI 1.013, 6.842); p < 0.01]. In SSc-patients without ILD, CWMA represents an important variable in exercise capacity and can be evaluated by the mediastinal window available in the HRCT images required for lung disease staging.

Abstract
Background
Frailty is a risk factor for presentation to the ED, in-hospital mortality, prolonged hospital stays and functional decline at discharge. Profiling the prevalence and level of frailty within the acute hospital setting is vital to ensure evidence-based practice and service development within the construct of frailty. The aim of this cross-sectional study was to establish the prevalence of frailty and co-morbidities among older adults in an acute hospital setting.

Methods
Data collection was undertaken by clinical research nurses and advanced nurse practitioners experienced in assessing older adults. All patients aged ≥ 65 years and admitted to a medical or surgical inpatient setting between 08:00 and 20:00 and who attended the ED over a 24-h period were screened using validated frailty and co-morbidity scales. Age and gender demographics, Clinical Frailty Scale (CFS), Charlson Co-morbidity Index (CCI) and admitting specialty (medical/surgical) were collected. Descriptive statistics were used to profile the cohort, and p values were calculated to ascertain the significance of results.

Results
Within a sample of 413 inpatients, 291 (70%) were ≥ 65 years and therefore were included in the study. 202 of these 291 older adults (70%) were ≥ 75 years. Frailty was investigated using validated clinical cut-offs on the CFS (not frail < 5; frail ≥ 5). Comorbidities were investigated using the Charlson Comorbidity Index (mild 1–2; moderate 3–4; severe ≥ 5). The median CFS was 6 indicating moderate frailty levels, and the median CCI score was 3 denoting moderate co-morbidity. In the inpatient cohort, 245 (84%) screened positive for frailty, while 223 (75%) had moderate-severe co-morbidity (CCI Mod 3–4, severe ≥ 5). No significant differences were observed across genders for CFS and CCI. In the ED, 81 patients who attended the ED were ≥ 65 years. The median CFS was 6 (moderate frailty), and the median CCI was 5 (severe co-morbidity level). Seventy-four percent (60) of participants screened positively for frailty (CFS ≥ 5), and 31% (25) had a CFS of 7 or greater (severely frail). Ninety-six percent (78) of patients had a moderate-severe level of comorbidity. No significant associations were found between the CFS and CCI and ED participants age, gender, and medical/surgical speciality usage.

Conclusion
There is a high prevalence of frailty and co-morbidity among older adults who present to the ED and require inpatient care. This may contribute to increased waiting times, lengths of stay, and the need for specialist intervention. With an increased focus on the integration of care for older adults across care transitions, there is a clear need for expansion of frailty-based services, staff training in frailty care and multidisciplinary team resources across the hospital and community setting.
