Carbon and nitrogen stable isotope ratios of soils and grasses as indicators of soil characteristics and biological taxa
2019
Abstract The use of stable isotope techniques can assist in understanding interactions of plants with various abiotic and biotic processes. In the research, we focused on carbon (C) and nitrogen (N) isotopes because they are the most important resources influencing plant function and the biogeochemical cycles. The 13C/12C and 15N/14N ratios in plants and in soils and the relationships between these ratios and biological and environmental factors of widely distributed native C3 plants (couch grass, plantain and yarrow) collected from two sites in St. Petersburg, Russia were studied. The soil characteristics of the sites were rather different. This had a significant effect on the isotope rati…
La casa ipertestuale. Le stanze e lo spazio-soglia
2008
Il saggio descrive i risultati di un'esperienza di seminario/workshop extracurriculare, svoltosi a Palermo nel 2005 (dal titolo: “Futura. Come abiteremo domani”). La metafora dell’ipertesto, spesso utilizzata da architetti, filosofi e urbanisti come metafora significativa per descrivere la condizione metropolitana contemporanea, risulta particolarmente efficace quale rappresentazione sintetica dell’idea di casa che abbiamo inteso indagare, per alcune sue qualità essenziali che trovano immediato riscontro nelle nuove modalità dell’abitare. All’interno del tema più generale della casa “ipertestuale”, la sperimentazione diretta dal Emanuele Palazzotto ha inteso esplorare alcune possibilità di …
Post-mortem alteration of diet-related enamel surface textures through artificial biostratinomy: A tumbling experiment using mammal teeth
2019
In the fossil record, teeth are often all that remains of a fossil organism. Dental microwear texture analysis (DMTA) is a common proxy for diet using dental wear features at the μm-scale, enabling comparative and quantitative assessments of various feeding traits in extant and extinct species. In extinct species, original diet-related dental wear features may be overprinted by post-mortem alteration including fluvial transport. Here we experimentally investigate the effects of mechanical alteration on diet-related 3D enamel surface texture (3DST) patterns of different mammal teeth. Post canine teeth of Equus sp., Capreolus capreolus and Otomys sp. are tumbled in sediment-water suspensio…
And the World Continues to Spin…: Secularism and Demystification in Good Omens
2018
Pratchett’s narratives tend to portray not only multicultural but also multireligious societies. In contrast to earlier writers of fantasy, however, Pratchett writes from a decidedly atheistic point of view, an issue Daniel Scott explores in depth in this chapter. He argues that co-authors Pratchett and Gaiman use Good Omens to perform what, following Rosemary Jackson’s theory of fantasy literature (1989), is a dual subversion; in using biblical prophecy to hold a mirror up to society, they also show the faults and cracks in the mirror itself, sometimes overtly, but mostly by implication. By reducing it to this level of intertextuality, they strip it of its higher or absolute metaphysical v…
EMBEDDING CONTEXT IN INVESTIGATIONS OF AFFECTIVE VARIABILITY: AGE DIFFERENCES IN AFFECT-HEALTH LINKS
2017
Context plays a potentially important role in explaining variability in affective experiences and yet, has often been overlooked in this line of research. The current study used data from a lifespan sample of 398 German participants ranging between 12–88 years of age (M = 40, SD = 20). Participants completed computer assisted personal interviews regarding health and well-being measures, as well as experience sampling assessments of daily affective experiences and events (e.g., uplifts). Three indices of positive affect (PA) were created: mean PA, PA reactivity to uplifts, and PA variability. In general, greater mean PA and lower PA reactivity and variability were associated with better heal…
PREDICTIVE ACCURACY OF FRAILTY MEASURES: OVERVIEW OF REVIEWS
2017
Frailty is an age-related state of high vulnerability to adverse health outcomes after a stressor event, predisposing individuals to progressive decline in different functional domains. A scoping search identified a large number of relevant systematic reviews (SRs) on predictive ability of frailty measures in older adults. Aiming to summarise this set of evidence an overview of reviews, based on the Joanna Briggs Institute (JBI) methodology, was conducted. This project “664367/FOCUS” was funded under the European Union’s Health Programme (2014–2020). The studies considered as eligible for inclusion were quantitative SRs including older adults aged 60 years or more, recruited from any type o…
Appetite for destruction: A psychometric examination and prevalence estimation of destructive leadership in Sweden
2021
There is a growing awareness that destructive leadership has a significant negative impact on employe outcomes. However, little is known about the content and dimensionality of this multidimensional concept, and there are few reliable measures available for organizations and researchers to evaluate these behaviors. Based on a representative sample (N = 1132) of the Swedish workforce, the aim of this study is threefold: first, to examine the factor structure and validity of an easy-to-use multidimensional destructive leadership measure (Destrudo-L)in the general Swedish work context; second, to identify destructive leadership profiles using latent profile analysis (LPA), and determine in wha…
Toward adjustment profiles for lower secondary student-athletes in the Finnish dual career context: A mixed-methods approach
2022
Engagement, burnout, and experiences are central concepts for understanding student-athlete adjustment in a dual career (DC) environment. As part of a larger 3-year, lower secondary sports schools pilot project, the aim of this study was to examine student-athletes’ DC adjustment in Finnish lower secondary sports schools at the end of the second academic year. By combining quantitative and qualitative methods, we sought to (a) identify adjustment profiles among student-athletes based on measures of engagement and burnout in school and sport and (b) to extract experiences that describe the distribution of student-athletes in the profiles. A latent profile analysis using questionnaire data fr…
Bordón : revista de pedagogía
2013
INTRODUCTION. In this paper we analyze the evolution in the learning approaches of two groups of first-year university students, one excellent and the other average, from a range of eleven degrees and nine colleges of the Polytechnical University of Valencia. These students were selected as excellent or average based on the marks they obtained on their University Entrance Exams. METHODS. We carried out a longitudinal study using quantitative analysis. The students answered the R-SPQ-2questionnaire (Biggs, Kember & Leung, 2001) that measures their learning approaches in three stages throughout the academic year, at the beginning, midway through and at the end of the year. RESULTS. The resear…
gNOMO: a multi-omics pipeline for integrated host and microbiome analysis of non-model organisms
2020
The study of bacterial symbioses has grown exponentially in the recent past. However, existing bioinformatic workflows of microbiome data analysis do commonly not integrate multiple meta-omics levels and are mainly geared toward human microbiomes. Microbiota are better understood when analyzed in their biological context; that is together with their host or environment. Nevertheless, this is a limitation when studying non-model organisms mainly due to the lack of well-annotated sequence references. Here, we present gNOMO, a bioinformatic pipeline that is specifically designed to process and analyze non-model organism samples of up to three meta-omics levels: metagenomics, metatranscriptomic…
