Two new species of Astrothelium are described from the Yungas forest in Bolivian Andes. Astrothelium chulumanense is characterised by pseudostromata concolorous with the thallus, perithecia immersed for the most part, with the upper portion elevated above the thallus and covered, except the tops, with orange pigment, apical and fused ostioles, the absence of lichexanthone (but thallus UV+ orange-yellow), clear hamathecium, 8-spored asci and amyloid, large, muriform ascospores with median septa. Astrothelium isidiatum is known only in a sterile state and produces isidia that develop in groups on areoles, but easily break off to reveal a medulla that resembles soralia. Both species, according to the two-locus phylogeny, belong to Astrothelium s.str. The production of isidia is reported from the genus Astrothelium and the family Trypetheliaceae for the first time.

Purpose: To quantify the impact of image noise on CT-based lung ventilation biomarkers calculated using Jacobian determinant techniques.Methods: Five mechanically ventilated swine were imaged on a multi-row CT scanner with acquisition parameters of 120 kVp and 0.6 mm slice thickness in static and 4-dimensional CT (4DCT) modes with respective pitches of 1 and 0.09. A range of tube current time product (mAs) values were used to vary image dose. On two dates, subjects received two 4DCTs: one with 10 mAs/rotation (low-dose, high-noise) and one with CT simulation standard of care 100 mAs/rotation (high-dose, low-noise). Additionally, 10 intermediate noise level breath-hold (BHCT) scans were acquired with inspiratory and expiratory lung volumes. Images were reconstructed with and without iterative reconstruction (IR) using 1 mm slice thickness. The Jacobian determinant of an estimated transformation from a B-spline deformable image registration was used to create CT-ventilation biomarkers estimating lung tissue expansion. 24 CT-ventilation maps were generated per subject per scan date: four 4DCT ventilation maps (two noise levels each with and without IR) and 20 BHCT ventilation maps (10 noise levels each with and without IR). Biomarkers derived from reduced dose scans were registered to the reference full dose scan for comparison. Evaluation metrics were gamma pass rate (Γ) with 2 mm distance-to-agreement and 6% intensity criterion, voxel-wise Spearman correlation (ρ) and Jacobian ratio coefficient of variation (CoVJR).Results: Comparing biomarkers derived from low (CTDIvol = 6.07 mGy) and high (CTDIvol = 60.7 mGy) dose 4DCT scans, mean Γ, ρ and CoVJR values were 93% ± 3%, 0.88 ± 0.03 and 0.04 ± 0.009, respectively. With IR applied, those values were 93% ± 4%, 0.90 ± 0.04 and 0.03 ± 0.003. Similarly, comparisons between BHCT-based biomarkers with variable dose (CTDIvol = 1.35–7.95 mGy) had mean Γ, ρ and CoVJR of 93% ± 4%, 0.97 ± 0.02 and 0.03 ± 0.006 without IR and 93% ± 4%, 0.97 ± 0.03 and 0.03 ± 0.007 with IR. Applying IR did not significantly change any metrics (p>0.05).Discussion: This work demonstrated that CT-ventilation, calculated using the Jacobian determinant of an estimated transformation from a B-spline deformable image registration, is invariant to Hounsfield Unit (HU) variation caused by image noise. This advantageous finding may be leveraged clinically with potential applications including dose reduction and/or acquiring repeated low-dose acquisitions for improved ventilation characterization.

Although associations between fear of fat and eating disorders (ED) have been frequently studied, it appears that the construct of fear of fat requires in-depth understanding to determine whether it is similar in individuals diagnosed with bulimia nervosa, anorexia nervosa, and individuals from the general population. The purpose of our study was to confirm the factor structure of the Goldfarb Fear of Fat Scale (GFFS) in clinical and non-clinical settings. This issue has not yet been investigated in the literature. Data were collected from 126 female patients diagnosed with ED and a total of 581 women from the general population. Our findings are highly consistent with the original single-factor structure of GFFS but only in the clinical sample. In the non-clinical sample, a good fit to the data has been achieved with a two-factor model composed of Fear of gaining weight and Fear of losing control over eating/weight. The Polish version of GFFS demonstrated good psychometric properties. It can be used as a fast screening tool to identify individuals with eating disorders and those at risk of developing such disorders. We recommend the two-factor model for non-clinical samples and the one-dimensional model for clinical samples for both research and practice.

W ostatnich dwudziestu latach widzimy znaczny wzrost zainteresowania współczuciem dla samego siebie (z ang. self-compassion) w wielu dziedzinach nauk, także w psychologii, pedagogice czy medycynie. Celem publikacji jest przedstawienie procesu polskiej adaptacji Skali Współczucia dla Samego Siebie (Self Compassion Scale) autorstwa Kristin Neff. Adaptacja przebiegła w dwóch etapach. Walidacja kulturowa skali polegała na tłumaczeniu skali na język angielski, a następnie tłumaczenia zwrotnego – z języka angielskiego na polski oraz zadbaniu o równoważność fasadową oraz funkcjonalną testu zgodnie z przyjętymi zasadami adaptacji kulturowej skal. Drugim etapem była walidacja psychometryczna skali w oparciu o przeprowadzone badania z udziałem 645 badanych z wykorzystaniem Skali Współczucia dla Samego Siebie (SCS- PL) oraz Metryczki uwzględniającej dane demograficzne badanych takie jak wiek, płeć, miejsce zamieszkania, wykształcenie oraz romantyczne związki. Przeprowadzone badania i uzyskane wyniki pozwalają stwierdzić, że polska wersja SCS jest wiarygodną i miarą samowspółczucia. SCS-PL uzyskała w badaniach zadowalające wyniki rzetelności i trafności. Skala może być stosowana do oceny współczucia wobec siebie oraz jego komponentów, zarówno w warunkach klinicznych jak i badawczych

Cel pracyCelem naszego badania obserwacyjnego było określenie , czy wybrane cechy osobowości są skorelowane ze stopniem wyrównania metabolicznego/czasem trwania cukrzycy u dorosłych pacjentów z T1DM.MetodaDane zebrano od 56 dorosłych pacjentów (40 mężczyzn) z T1DM leczonych w ośrodku o trzecim stopniu referencyjności. Cechy osobowości „Wielkiej Piątki” oceniano za pomocą kwestionariusza “NEO-Five Factor Inventory”. Kilka zmiennych uzyskano po sczytaniu osobistych pomp insulinowych, glukometrów i zaślepionego systemu ciągłego monitorowania glikemii (CGM).WynikiWszystkie cechy osobowości oprócz neurotyczności (niski poziom cechy) wykazywały przeciętne nasilenie. Ugodowość była skorelowana z większością zmiennych uzyskanych z systemu CGM. Większa sumienność wiązała się z dłuższym czasem trwania cukrzycy. Większa neurotyczność korelowała z większą zmiennością glikemii (GV), podczas gdy wysoka ekstrawersja wiązała się z niższym wskaźnikiem GV. Niższa Otwartość była związana z wydłużeniem czasu klinicznie istotnej hipoglikemiiWnioskiNasze badanie sugeruje, że cechy osobowości przejawiają się w indywidualnym podejściu do leczenia cukrzycy i regulacji emocji, co przekłada się również na stosunek do leczenia. Z drugiej strony, ogólne wyniki cech pacjentów z T1DM były zgodne z normami niepsychiatrycznymi dla osób zdrowych, co obala mity i stereotypy sugerujące, że choroba przewlekła jest zwykle związana z psychopatologią.

Microbiology (medical) ,Microbiology - Abstract
In the past few years, new phylogenetic lineages in Trebouxia were detected as a result of molecular approaches. These studies included symbiont selectivity in lichen communities, transects along altitudinal gradients at local and global scales and the photobiont diversity in local populations of lichen-forming fungal species. In most of these studies, phylogenetic and haplotype analyses based on the internal transcribed spacer (ITS) locus have continuously allowed the recognition of new monophyletic lineages, which suggests that still numerous undiscovered Trebouxia lineages can be hidden in lichens from unexplored areas, especially in the tropics. Here, we estimated the biodiversity of photobionts in Bolivian Andean vegetation and assessed their specificity. About 403 lichen samples representing 42 genera, e.g., Haematomma, Heterodermia, Hypotrachyna, Lecanora, Lepra, Leucodermia, Parmotrema, Pertusaria, Polyblastidium, and Usnea, containing Trebouxia photobionts, were analyzed. ITS ribosomal DNA (rDNA) and rbcL markers were used. We obtained Trebouxia sequences from Bolivian samples belonging to already described clades A, C, I, and S. Thirty-nine Trebouxia lineages were distinguished within these clades, while 16 were new. To reveal the structure of the community of Bolivian photobionts and their relationships with mycobionts, the comparative effects of climate, altitude, geographical distances, substrate, and habitat type, as well as functional traits of lichens such as growth forms, propagation mode and secondary metabolites, were analyzed. Furthermore, new Bolivian records were included in analysis on a global scale. In our study, the mycobiont genus or even species are the most important factors correlated with photobiont identity. Moreover, we revealed that the community of Bolivian photobionts is shaped by altitude.

Six species of Sticta are described as new to science on the basis of material from Bolivia and supported by phylogenetic analysis of the fungal ITS barcoding marker. The species were resolved in all three of the clades (I, II, III) widespread and common in the Neotropics, as defined in an earlier study on the genus. Comparison with material from neighbouring countries (i.e. Colombia, Ecuador, Peru) suggests that these new species may be potentially endemic to the Bolivian Yungas ecoregion. For each species, a detailed morphological and anatomical description is given. Sticta amboroensis Ossowska, Kukwa, B. Moncada & Lücking is a medium-sized green-algal species with laminal to submarginal apothecia with hirsute margins and with light to dark brown lower tomentum. Sticta aymara Ossowska, Kukwa, B. Moncada, Flakus, Rodriguez-Flakus & Lücking is a comparatively small cyanobacterial taxon with Nostoc as photobiont, laminal, richly branched, aggregate isidia and a golden to chocolate-brown lower tomentum. The medium-sized, cyanobacterial S. bicellulata Ossowska, Kukwa, B. Moncada & Lücking has cyanobacterial photobiont, bicellular ascospores, apothecia with white to golden-brown hairs on the margins, K+ violet apothecial margin (ring around disc) and epihymenium and a white to dark brown lower tomentum. In contrast, the green-algal species, S. carrascoensis Ossowska, Kukwa, B. Moncada & Lücking is characterised by its large size, apothecia with dark brown hairs on the margins and a yellow medulla. The cyanobacterial S. catharinae Ossowska, B. Moncada, Kukwa, Flakus, Rodriguez-Flakus & Lücking forms stipitate thalli with Nostoc as photobiont, abundant, laminal to submarginal apothecia and a golden-brown lower tomentum. Finally, the cyanobacterial S. pseudoimpressula Ossowska, Kukwa, B. Moncada & Lücking produces laminal apothecia with an orange-yellow line of pruina along the margins which reacts K+ carmine-red. In addition to the six new Bolivian taxa, the cyanobacterial S. narinioana B. Moncada, Ossowska & Lücking is described as new from Colombia and it represents the closely-related sister species of the Bolivian S. aymara; it differs from the latter largely in the marginal instead of laminal isidia.

Physiology ,Physiology (medical) - Abstract
Vessel segmentation in the lung is an ongoing challenge. While many methods have been able to successfully identify vessels in normal, healthy, lungs, these methods struggle in the presence of abnormalities. Following radiotherapy, these methods tend to identify regions of radiographic change due to post-radiation therapytoxicities as vasculature falsely. By combining texture analysis and existing vasculature and masking techniques, we have developed a novel vasculature segmentation workflow that improves specificity in irradiated lung while preserving the sensitivity of detection in the rest of the lung. Furthermore, radiation dose has been shown to cause vascular injury as well as reduce pulmonary function post-RT. This work shows the improvements our novel vascular segmentation method provides relative to existing methods. Additionally, we use this workflow to show a dose dependent radiation-induced change in vasculature which is correlated with previously measured perfusion changes (R2 = 0.72) in both directly irradiated and indirectly damaged regions of perfusion. These results present an opportunity to extend non-contrast CT-derived models of functional change following radiation therapy.

This study is designed to test whether sentiment analysis using Twitter data can predict the level of public anxiety regarding the war in Ukraine measured by classical surveys. In this study, we use two sentiment analysis methods: Latent Semantic Scaling (LSS) and lexicon analysis utilizing affective word norms. Those two methods were selected as the most promising. When their results were initially compared with survey data, they showed a satisfactory compliance level between Twitter and survey data. Therefore, in the next phase, we want to check whether such results are stable across time and if the results of the selected sentiment analysis methods will still be consistent with the Twitter data collected in the future.

This article provides an outline of the classification of the kingdom Fungi (including fossil fungi. i.e. dispersed spores, mycelia, sporophores, mycorrhizas). We treat 19 phyla of fungi. These are Aphelidiomycota, Ascomycota, Basidiobolomycota, Basidiomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Entorrhizomycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota, Mucoromycota, Neocallimastigomycota, Olpidiomycota, Rozellomycota and Zoopagomycota. The placement of all fungal genera is provided at the class-, order- and family-level. The described number of species per genus is also given. Notes are provided of taxa for which recent changes or disagreements have been presented. Fungus-like taxa that were traditionally treated as fungi are also incorporated in this outline (i.e. Eumycetozoa, Dictyosteliomycetes, Ceratiomyxomycetes and Myxomycetes). Four new taxa are introduced: Amblyosporida ord. nov. Neopereziida ord. nov. and Ovavesiculida ord. nov. in Rozellomycota, and Protosporangiaceae fam. nov. in Dictyosteliomycetes. Two different classifications (in outline section and in discussion) are provided for Glomeromycota and Leotiomycetes based on recent studies. The phylogenetic reconstruction of a four-gene dataset (18S and 28S rRNA, RPB1, RPB2) of 433 taxa is presented, including all currently described orders of fungi., Nalin N.

Polylepis tarapacana forms one of the highest-altitude woodlands worldwide. Its populations are experiencing a decline due to unsustainable land-use practices, climate change, and fungal infection. In Sajama National Park in Bolivia, Polylepis tarapacana is affected by a disease caused by the pleosporalean fungus Leptosphaeria polylepidis, recently described in 2005. In this study, the integrative morphological and molecular analyses using sequences from multiple DNA loci showed that it belongs to the genus Paraleptosphaeria (Leptosphaeriaceae, Pleosporales). Accordingly, the appropriate new combination, Paraleptosphaeria polylepidis, is made. Pseudothecia of Pa. polylepidis were found to be overgrown by enigmatic conidiomata that were not reported in the original description of this fungus. Morphological and molecular analyses using sequences from two DNA loci revealed that they belong to an undescribed genus and species in the family Dictyosporiaceae (Pleosporales). The new generic and specific names, Sajamaea and S. mycophila, are introduced for this unusual fungus.

Neotropical mountain forests are characterized by having hyperdiverse and unusual fungi inhabiting lichens. The great majority of these lichenicolous fungi (i.e., detectable by light microscopy) remain undescribed and their phylogenetic relationships are mostly unknown. This study focuses on lichenicolous fungi inhabiting the genus Lobariella (Peltigerales), one of the most important lichen hosts in the Andean cloud forests. Based on molecular and morphological data, three new genera are introduced: Lawreyella gen. nov. (Cordieritidaceae, for Unguiculariopsis lobariella), Neobaryopsis gen. nov. (Cordycipitaceae), and Pseudodidymocyrtis gen. nov. (Didymosphaeriaceae). Nine additional new species are described (Abrothallus subhalei sp. nov., Atronectria lobariellae sp. nov., Corticifraga microspora sp. nov., Epithamnolia rugosopycnidiata sp. nov., Lichenotubeufia cryptica sp. nov., Neobaryopsis andensis sp. nov., Pseudodidymocyrtis lobariellae sp. nov., Rhagadostomella hypolobariella sp. nov., and Xylaria lichenicola sp. nov.). Phylogenetic placements of 13 lichenicolous species are reported here for Abrothallus, Arthonia, Globonectria, Lawreyella, Monodictys, Neobaryopsis, Pseudodidymocyrtis, Sclerococcum, Trichonectria and Xylaria. The name Sclerococcum ricasoliae comb. nov. is reestablished for the neotropical populations formerly named S. lobariellum (Sclerococcales). A key to sexual and asexual states of 40 species of lobariellicolous ascomycetous fungi is provided. Teleomorph-anamorph connections were established for several species using molecular methods and/or visual observations in nature. Additionally, we found that the anamorphic species Cornutispora ophiurospora inhabiting Lobariella was often accompanied by ascomata of Spirographa. Results of phylogenetic analyses, including newly generated sequences of several Cornutispora and Spirographa species inhabiting various host lichens, support the conclusion that Cornutispora is a synonym of Spirographa. Our Maximum Likelihood inference based on multiple loci show that all studied Spirographa (including Cornutispora) belong to a new lineage within Ostropales. Based on these highly supported phylogenetic placements and the distinct character states of their conidiomata, in comparison with other Lecanoromycetes, a new family is proposed – Spirographaceae fam. nov. This new lineage includes broadly distributed mycoparasites, inhabiting various lichen and fungal hosts, and representing an early diversification event preceding the lichen-forming clade of Fissurinaceae, Gomphillaceae and Graphidaceae. Two lichenicolous species, Asteroglobulus giselae and Pleoscutula arsenii, were found to be nested within the Spirographa clade, and their teleomorph-anamorph connections were confirmed based on genotypic and phenotypic data. This phylogenetic result is corroborated by their highly similar ascomata anatomy. Together these results strongly indicate that both species are congeneric with Spirographa. As a result, four new species (S. aggregata sp. nov., S. galligena sp. nov., S. maroneae sp. nov., and S. parmotrematis sp. nov.) and 15 new combinations are proposed (Spirographa ascaridiella comb. nov., S. arsenii comb. nov., S. ciliata comb. nov., S. giselae comb. nov., S. herteliana comb. nov., S. hypotrachynae comb. nov., S. intermedia comb. nov., S. lichenicola comb. nov., S. limaciformis comb. nov., S. ophiurospora comb. nov., S. pittii comb. nov., S. pyramidalis comb. nov., S. triangularis comb. nov., S. tricupulata comb. nov., and S. vermiformis comb. nov.). Species of the genus Spirographa, as outlined here, are strongly host-specific, mainly at the generic level of their host. Some host genera can harbour more than one Spirographa species.

Shifts in climate along elevation gradients structure mycobiont–photobiont associations in lichens. We obtained mycobiont (lecanoroid Lecanoraceae) and photobiont (Trebouxia alga) DNA sequences from 89 lichen thalli collected in Bolivia from a ca. 4,700 m elevation gradient encompassing diverse natural communities and environmental conditions. The molecular dataset included six mycobiont loci (ITS, nrLSU, mtSSU, RPB1, RPB2, and MCM7) and two photobiont loci (ITS, rbcL); we designed new primers to amplify Lecanoraceae RPB1 and RPB2 with a nested PCR approach. Mycobionts belonged to Lecanora s.lat., Bryonora, Myriolecis, Protoparmeliopsis, the “Lecanora” polytropa group, and the “L.” saligna group. All of these clades except for Lecanora s.lat. occurred only at high elevation. No single species of Lecanoraceae was present along the entire elevation gradient, and individual clades were restricted to a subset of the gradient. Most Lecanoraceae samples represent species which have not previously been sequenced. Trebouxia clade C, which has not previously been recorded in association with species of Lecanoraceae, predominates at low- to mid-elevation sites. Photobionts from Trebouxia clade I occur at the upper extent of mid-elevation forest and at some open, high-elevation sites, while Trebouxia clades A and S dominate open habitats at high elevation. We did not find Trebouxia clade D. Several putative new species were found in Trebouxia clades A, C, and I. These included one putative species in clade A associated with Myriolecis species growing on limestone at high elevation and a novel lineage sister to the rest of clade C associated with Lecanora on bark in low-elevation grassland. Three different kinds of photobiont switching were observed, with certain mycobiont species associating with Trebouxia from different major clades, species within a major clade, or haplotypes within a species. Lecanoraceae mycobionts and Trebouxia photobionts exhibit species turnover along the elevation gradient, but with each partner having a different elevation threshold at which the community shifts completely. A phylogenetically defined sampling of a single diverse family of lichen-forming fungi may be sufficient to document regional patterns of Trebouxia diversity and distribution.

Lecidea Ach. in its broad sense, is one of the largest and most heterogeneous genus of lichenized fungi with a worldwide distribution and with diversity hotspots located in the temperate and polar regions. The genus belongs to a crust-like microlichen group and inhabits many different substrates (e.g., bark, rock, wood, soil, mosses). Lecidea does not form a coherent systematic entity, and previous studies have revealed it as a polyphyletic assemblage with species spread across various families within the Lecanoromycetes. The present study is a modern taxonomic revision of southern South America non-saxicolous lecideoid lichens based on morphological, anatomical and chemical characters. A total of 27 species belonging to ten genera are recognized. The current study reveals a substantial, previously hidden, diversity of lichens in Valdivian temperate and Magellanic subpolar forests; increasing the number of known lecideoid lichens in the studied area. Many new regional records are also reported including six species new to South America (Bryobilimbia hypnorum, Hertelidea botryosa, H. eucalypti, Japewiella tavaresiana, Placynthiella oligotropha, and Ramboldia brunneocarpa). The following species are here described as new to science: Bryobilimbia flakusii Rodr. Flakus sp. nov. (Argentina), B. pallida Rodr. Flakus sp. nov. (Argentina, Chile), Hertelidea printzenii Rodr. Flakus sp. nov. (Argentina), H. stipitata Rodr. Flakus sp. nov. (Argentina, Chile), “Lecidea” vobisii Rodr. Flakus sp. nov. (Argentina), and Ramboldia australis Rodr. Flakus sp. nov. (Argentina, Chile). All species are described and illustrated in detail, and an identification key to the species is provided. In addition, as a result of a revision of available type material, a list of 48 additional species excluded from this study, including brief remarks on their taxonomical affiliations, is provided.

PurposeJob search behavior is an important factor of an individual's career. In this study, proactive individuals' search for career opportunities during the transition from unemployment to employment is investigated. This investigation concentrates on the “in-between jobs” phase to better understand career transition. Proactive coping is a particularly important aspect of the transition from unemployment to work.Design/methodology/approachUsing the career self-management model and proactive coping theory, this paper establishes a conceptual model and adopts path analysis to examine the model with a sample of 208 unemployed workers from Poland.FindingsThe results indicate both direct and indirect effects for proactive coping on job-seeking behavior. Unemployed job seekers, with greater proactive coping, intensify their job search behavior and increase their chances for re-employment.Practical implicationsProactive coping is an important factor in career development. The findings of this study are a promising starting point for career self-development training for unemployed workers in transition.Originality/valueMost of the training for the unemployed prepares them to react and adapt to ongoing circumstances. Our findings show the importance of being proactive during active coping with unemployment.

Methodological awareness is one of the forms of social consciousness. It is considered one of the basic regulators of scientific research activities. Despite the abundance of theoretical deliberation over the structure of methodological awareness in literature, little attention is devoted to individual qualities of researchers who can be studied for displaying correlates of methodological awareness. One of the potential areas for such studies are cognitive variables which should be understood as mind types which determine human cognitive preferences in two dimensions: perception vs. intuition and feelings vs. thinking. Personality, considered to be the basic regulator of human activity, is yet another field where correlations of methodological awareness can be researched. The author presents the results of her study in which she searched for hypothetical correlates of methodological awareness.

New collections are reported of the monospecific genusPolypyrenula, an apparently extinct and doubtfully lichenized fungus, typically classified in thePyrenulaceae. Anatomical studies reveal that it is facultatively lichenized. The structure of its hamathecium suggests affinities with Dothideomycetes rather than Eurotiomycetes. Molecular analysis using nuLSU and mtSSU markers demonstrates for the first time its inclusion inTrypetheliaceae, outside the core genera as part of the early diverging lineages in this family. The known distribution ofPolypyrenulais extended to Mexico and South America, new information on its phorophyte associations is provided, and the namePolypyrenula sexlocularisis reinstated as the correct name for this species.

General Psychology - Abstract
The aim of the article is to present a description of the psychometric properties of the Polish adaptation of the Movie Consumption Questionnaires (MCQ) – Immersion and MCQ – Experience. The instrument, created by Fornerino, Helme-Guizon and Gotteland (2008) allows measuring movie consumption in terms of immersion, the intensity of emotions and the intensity of social interactions during the screening. The Polish adaptation of the tool involved two stages, whose participants were movie-goers attending screening events at a cinema ( N=577). The factor structure of the adapted instrument strongly resembles that obtained in the original study (RMSEA0.95, SRNR0.8, ω>0.8). Criterion validity was also verified through the use of questionnaires that examine the following: affect – PANAS-X (Fajkowska & Marszał-Wiśniewska, 2009), emotionality – HEXACO (Szarota et al., 2007) and mindfulness – Mindful Attention Awareness Scale (Skala Świadomej Obecności; Radoń, 2014). Results of the analyses suggest that the adapted scales may be used as satisfactory tools for measuring movie consumption. By the same token, they may be useful in further psychological exploration of the movie screening phenomenon, with particular regard to immersion, emotional reactions and social interactions of the viewer.

BACKGROUND Employees in the aviation sector constitute an especially interesting professional group due to a lack of empirical data on their psychological functioning, and the fact that this industry is currently experiencing a phase of dynamic development. However, taking into consideration the automation and specific qualities of the sector, human resources should be given much more attention as they are constantly challenged and face diverse difficulties at work while cooperating in various organic and non-organic teams. MATERIAL AND METHODS The study included 326 employees of Pyrzowice (Poland), Szymany (Poland), and Kosice (Slovakia) airports (however, people employed at the Polish airports were predominant, N = 250). The average age of the participants was 39.3 years, and the sample was predominantly male (N = 278, 85.3%). During the research procedure, the following questionnaires were used: the Feeling of Threat in the Workplace Questionnaire, the Feeling of Stress Questionnaire, the 10-Item Personality Inventory, and the Mini-COPE Stress Inventory. RESULTS The regression analysis indicated that personality variables did not allow for predicting the level of stress. However, the helplessness-oriented style (β = 0.191, p = 0.004), avoidant behaviors (β = 0.244, p < 0.001), and the feeling of threat (β = 0.147, p = 0.009) were significant predictors of the feeling of stress, and their high level corresponded with a higher level of stress. The final model explained 23% of the total variance in the feeling of stress. CONCLUSIONS Based on the results, practical recommendations should concern developing employees' skills related to monitoring stressors and strengthening proactivity in difficult or threatening situations. Such proactive strategies may decrease the tendency to use avoidant and helplessness-oriented behaviors that may cause a higher level of stress perceived by employees. Also, the authors recommend providing training and support using some cognitive behavioral techniques because it seems that the regular application of those methods supports the development of agency and control while facing challenging situations.

Recent functional lung imaging studies have presented evidence of an “indirect effect” on perfusion damage, where regions that are unirradiated or lowly irradiated but that are supplied by highly irradiated regions observe perfusion damage post-radiation therapy (RT). The purpose of this work was to investigate this effect using a contrast-enhanced dynamic CT protocol to measure perfusion change in five novel swine subjects. A cohort of five Wisconsin Miniature Swine (WMS) were given a research course of 60 Gy in five fractions delivered locally to a vessel in the lung using an Accuray Radixact tomotherapy system with Synchrony motion tracking to increase delivery accuracy. Imaging was performed prior to delivering RT and 3 months post-RT to yield a 28–36 frame image series showing contrast flowing in and out of the vasculature. Using MIM software, contours were placed in six vessels on each animal to yield a contrast flow curve for each vessel. The contours were placed as follows: one at the point of max dose, one low-irradiated (5–20 Gy) branching from the max dose vessel, one low-irradiated (5–20 Gy) not branching from the max dose vessel, one unirradiated (

The main aims of this work were to assess phylogenetic relationships of the trentepohlialean photobionts in tropical, mainly sterile, lichens collected in Bolivia, to examine their genetic diversity, host specificity, and the impact of habitat factors on the occurrence of Trentepohliales. Based on rbcL marker analysis, we constructed a phylogenetic tree with eight major clades of Trentepohliales, of which seven free-living species are intermingled with lichenized ones. Our analyses show that the studied photobionts are scattered across the phylogenetic tree and algae from temperate and tropical regions do not form monophyletic groups, except within one clade that seems to be restricted to the tropics. There is no significant occurrence pattern of lichenized Trentepohliaceae on a specific substratum, except Cephaleuros spp. and Phycopeltis spp., which are restricted to leaves, while some clades with lichenized algae may be specialized to tree bark and wood. Moreover, we found two patterns of associations: first, closely related algae can associate with distantly related mycobionts; second, some other trentepohlioid algae associate with selected lineages of fungi (e.g., Arthoniaceae or Graphidaceae). We also found that some lineages of photobionts are even more selective and associate exclusively with one species (e.g., Dichosporidium nigrocinctum, Diorygma antillarum) or closely related lichen-forming fungi (Herpothallon spp.). Concluding, we found that occurrence of some trentepohlialean photobionts may correlate with the particular type of the mycobiont.

The elucidation of Fermi resonances impact on the IR spectral density (SD) of weak hydrogen bonded systems is still subject of an ongoing debate. We present, in this paper, a simple quantum approach that may illumine the contribution of Fermi resonances, resulting from the interaction between the high stretching and bending modes, on the SD of the υ S ( Cl – H → ) band in gaseous ( CH 3 ) 2 O … HCl Complex and address the question whether there is Fermi resonances phenomenon in such weak hydrogen bonded complexes. We analyzed the problem by considering a quantum approach taking into account the following hypotheses: (i) the low frequency stretching mode (slow mode) of the hydrogen bond is represented by a Morse potential, (ii) the high stretching mode (fast mode) is considered to harmonic, (iii) the υ S ( Cl – H → ) phase coherence is lost because of the coupling between the fast and slow modes, and because of the coupling between the fast and the bending mode, (iv) the SD is obtained within the framework of Kubo’s theory, according to which the SD is the Fourier transform of the transition dipole moment autocorrelation function which characterises the lineshape of the mid infrared υ S ( Cl – H → ) absorption band, (v) the direct relaxation mechanism of the υ S ( Cl – H → ) stretching band is incorporated by aid of the quantum treatment of Rosch and Ranter for which for the autocorrelation function decays exponentially on time, (vi) the indirect relaxation mechanism of the bending mode is introduced by aid of complex energy levels’ method for which the Hamiltonian eigenvalues of the H-bonded system, computed in the absence of damping, imaginary parts reflecting the irreversible influence of the medium on the bending mode. Using a set of physically reasonable parameters as input into the presented approach, the numerical experimentations have shown the capability of this simple model, which anharmonically couple the high stretching mode together with the slow and bending modes, to explain the main spectroscopic features of the υ S ( Cl – H → ) band in gaseous ( CH 3 ) 2 O … HCl Complexes. A good agreement between the simulated and experimental lineshapes is illustrated and a deep study of the role of each mechanism on the υ S ( Cl – H → ) band is elucidated.

This study adapts the Self-Compassion Scale into Polish and tests the validity, reliability and factor structure of its measures. In the first phase of the research (Study I), 645 respondents were assessed using the NEO-FFI Scale, the Self-Esteem Scale and a back-translated version of the Self-Compassion Scale. The aim of Study I is to analyse the factor structure of the Polish adaptation of the Self-Compassion Scale. The results of analyses using structural equation modelling and exploratory structural equation modelling confirm the six-component structure of the Self-Compassion Scale and the possibility of distinguishing a single primary factor. The results of these analyses indicate that self-compassion is conceptually distinctive from personality traits and self-judgement. In the second phase of the study (Study II), 688 respondents were assessed and the findings show that self-compassion is a predictor of depressive symptoms, trait anxiety, and satisfaction with life, and is also linked to emotional intelligence. In conclusion, the findings of this study show that the Polish version of the Self-Compassion Scale is a reliable and valid measure of self-compassion.

Leprariacryptovouauxii is described as a new semicryptic species similar to L.vouauxii, from which it differs geographically (South America) and phylogenetically; both species differ in nucleotide position characters in nucITS barcoding marker. Leprariaharrisiana is reported as new to South America and L.nothofagi as new to Antarctica, Bolivia, and Peru. Leprariaincana (South American records are referred to L.aff.hodkinsoniana) and L.vouauxii (most South American records are referred to L.cryptovouauxii) should be excluded at least temporarily from the lichen list of South America. All records previously referred to as L.alpina from Bolivia and Peru belong to L.nothofagi. Most of Bolivian records of L.pallida belong to L.harrisiana. Leprariaborealis and L.caesioalba should be included in L.neglecta. Leprariaachariana, L.impossibilis, and L.sipmaniana are sequenced for the first time.

Lichen-inhabiting fungi are highly specialized mycoparasites, commensals or rarely saprotrophs, that are common components of almost every ecosystem, where they develop obligate associations with lichens. Their relevance, however, contrasts with the relatively small number of these fungi described so far. Recent estimates and ongoing studies indicate that a significant fraction of their diversity remains undiscovered and may be expected in tropical regions, in particular in hyperdiverse fog-exposed montane forests. Here, we introduce the new genus Zhurbenkoa, from South America and Europe, for three lichenicolous fungi growing on thalli of the widespread lichen genus Cladonia (Lecanorales). Phylogenetic analyses based on combined sequence data of mt and nuc rDNA obtained from Andean populations (Bolivia) placed Zhurbenkoa as a member of Malmideaceae, a recently introduced family of lichen-forming fungi in the class Lecanoromycetes. Zhurbenkoa is closely related to the genera Savoronala and Sprucidea. The new genus is characterized by the development of grayish brown to almost black apothecia lacking an evident margin, an epihymenium interspersed with crystals (often seen as pruina), a strongly conglutinated hymenium made of noncapitate and sparsely branched paraphyses, a colorless exciple composed of radially arranged hyphae, a Lecanora/Micarea-like ascus type, and aseptate or 1-septate ellipsoidal colorless ascospores. Zhurbenkoa includes two Neotropical (Z. cladoniarum, Z. latispora) and one widespread (Z. epicladonia) species. The lichenicolous trophic mode is documented for the first time in the Malmideaceae, which until now included only lichen-forming associations between fungi and green algae., This research was financially supported by the National Science Centre (NCN) in Poland (DEC-2013/11/D/NZ8/03274).

Structural optimization, molecular docking analysis, electronic and vibrational properties have been investigated for the 1-benzofuran-2-carboxylic acid (2BF) and 1-benzofuran-3-carboxylic acid (3BF) using DFT/B3LYP/6-311++G(d,p) level of theory. The theoretical parameters have a very good consistency with the experimental ones. The weak intermolecular interactions were analyzed by different tool such as: Hirshfeld surfaces, topological analysis and natural bond orbital studies. The nonlinear optical properties have been investigated. Molecular electrostatic potential and frontier molecular orbitals (FMOs) analysis have been carried out to understand the reactivity of the molecule. In addition, TD-DFT calculation is initiated to simulate the UV-vis absorption spectrum and to determine several important electronic properties like HOMO-LUMO gap energy and electronic transitions. The complete vibrational assignments and the force constants were reported for monomer and dimers of both acids. The biological activities of the tow acids have been studied via molecular docking analysis. The later calculations prove that the studied acids have an inhibitor effect against cancer and microbial diseases.

The following paper presents the existing body of research on personality traits (within the framework of personality trait theory and Marvin Zuckerman's sensation seeking theory) of individuals engaging in high-risk sports, especially mountaineering and alpinism. In the review, two perspectives of theoretical analysis were taken into consideration: a psychological (concerning reflections on non-pathological personality characteristics of mountaineers) and a psychopathological one (concerning research on hypothetically pathological dimensions of the following traits). In both psychological and psychopathological perspective, the importance of sensation/stimulation seeking (understood as one of the personality dimensions) and deficiency of trait anxiety were analyzed. Both determinants can be linked with type T personality. In addition, numerous studies suggest that traits such as neuroticism, extraversion and conscientiousness may play important role in personality regulation of mountaineers. The presented reflection was supplemented by early reports referring to possible psychopathological traits, which may hypothetically indicate some personality disorders. The authors highlight the limitations of previous studies and point out possible directions of future research, in particular - necessity of including motivational factors, associated with engaging in high-risk sport activities.

PURPOSE To create a dose-response model that predicts lung ventilation change following radiation therapy, and examine the effects of out-of-phase ventilation. METHODS The dose-response model was built using 27 human subjects who underwent radiation therapy (RT) from an IRB-approved trial. For each four-dimensional computed tomography, two ventilation maps were created by calculating the N-phase local expansion ratio (LERN ) using most or all breathing phases and the 2-phase LER (LER2 ) using only the end inspiration and end expiration breathing phases. A polynomial regression model was created using the LERN ventilation maps pre-RT and post-RT and dose distributions for each subject, and crossvalidated with a leave-one-out method. Further validation of the model was performed using 15 additional human subjects using common statistical operating characteristics and gamma pass rates. RESULTS For voxels receiving 20 Gy or greater, there was a significant increase from 52% to 59% (P = 0.03) in the gamma pass rates of the LERN model predicted post-RT Jacobian maps to the actual post-RT Jacobian maps, relative to the LER2 model. Additionally, accuracy significantly increased (P = 0.03) from 68% to 75% using the LERN model, relative to the LER2 model. CONCLUSIONS The LERN model was significantly more accurate than the LER2 model at predicting post-RT ventilation maps. More accurate post-RT ventilation maps will aid in producing a higher quality functional avoidance treatment plan, allowing for potentially better normal tissue sparing.

Oxindole (indolin-2-one, Ox) is a unique and a crucial molecular system in spectroscopic studies. Indole is the core structure of many substances found in the human body (tryptophan, serotonin) and the indole alkaloids have highly differentiated pharmacological properties such as analgesic, anti-fever and anti-inflammatory. The Ox's structural results given in the Cambridge Structural Database revealed the existence of only one crystalline form of Ox, referred to the α-form. However, we have experimentally noticed the existence of two polymorphic forms during the crystallization of Ox. Furthermore, the significant spectral differences that we have observed in the solid state infrared spectra of these two forms additionally confirm the existence of the polymorphism phenomenon. Of the four polymorphic forms of Ox, two of them – α - and β-forms – were of particular interest. In the crystalline lattices of both polymorphs, we observed a similar pattern of molecular arrangements giving rise to the supramolecular synthon according to the terminology of Etter. Moreover, hydrogen bonds in the dimer of the α-form are found to be non-equivalent (non-centrosymmetric dimers), having a length of 2797 A and 2979 A, respectively. Comparatively, in the most densely packed crystalline structure of Ox, the β-form, the dimer is formed by a pair of almost identical intermolecular hydrogen bonds and consequently the crystals of β-form exhibited spectral properties typical to centrosymmetric hydrogen bond dimers. In addition, the spectroscopic studies that we have conducted to polymorphic forms of Ox, isotopically diluted with deuterium, show the dramatic influence of isotopic substitution in the hydrogen bridge on the infrared spectra of hydrogen bonding. Thus, the main goal of this work is the proposition of a theoretical approach that can describe the main features of the crystalline infrared spectra of the Ox polymorphs. The proposed approach is based on the phenomenon of the exciton coupling results directly from intermolecular interactions in the vibrationally excited state which leads to the delocalization of the excitation over the molecules in the lattice and to the Davydov splitting effect in the crystalline spectra.

The current study examines whether intelligent adolescents are liked more by their peers, does this likeability assessment remains constant over time, and do intelligent adolescents like certain people or everyone? For this purpose, we recruited seven classes of adolescents at the beginning of the first school year. We administered an intelligence test and gathered peer-reported information regarding the liking relations. To examine the dynamics of such associations, we repeated the measurement three months and one year later. The results of the Temporal Exponential Random Graph Model revealed that intelligent adolescents are liked more. However, these highly intelligent adolescents did not reciprocate such relations, as they liked fewer people than those who were less intelligent. This finding was stable both across short- and long-term and could be explained by the fact that those who are intelligent, tend to only like other intelligent peers, representing a fewer number of individuals. Our results suggest that intelligence is important in the explanation of the relation of liking.

A new coprinoid fungus, Coprinopsis rugosomagnispora, is described from Poland (Central Europe). Its macromorphological characters are similar to species belonging to the subsection Nivei of Coprinus s.l. However, C. rugosomagnispora has unique micromorphological characters: very large, ornamented spores, voluminous basidia and cystidia, and smooth veil elements. The large spores and pattern of spore ornamentation (densely pitted) make this species unique within all coprinoid species described so far. The structure (arrangement and shape) of veil elements in C. rugosomagnispora is intermediate between members of the subsections Nivei and Lanatuli of Coprinus s.l. Molecular phylogenetic analyses, based on single-locus (ITS) maximum likelihood and Bayesian evolutionary trees recovered C. rugosomagnispora within a lineage containing species having morphological characters of the subsection Lanatuli (though within the so-called Atramentarii clade) that contradicts its morphological similarity to members of the subsection Nivei.

Faced with increasing rates of biodiversity loss and modest conservation budgets, it is essential that natural resource managers allocate their financial resources in a cost-effective manner and provide transparent evidence for extra funding. We developed the 'Cost-Effective Resource Allocator', a Microsoft Excel-based decision support tool to assist natural resource managers and policy makers, to prioritize the set of management strategies that maximize the total number of years that a suite of species is expected to persist given a budget constraint. We describe this tool using a case study of four locally threatened species from the Australian Commonwealth National Park of Christmas Island in the Indian Ocean. These include: a native fern (Pneumatopteris truncata), the Christmas Island Red Crab (Gecarcoidea natalis), the Golden Bosun (Phaethon lepturus fulvus), and Abbott's Booby (Papasula abbotti). Under a hypothetical budget of 8,826,000 AUD over ten years, in which all species are considered equal, our tool recommends funding: fern propagation and planting, rat control, cat control, and Yellow Crazy Ant (Anoplolepis gracilipes) survey and control. We found that the cost-effectiveness rankings of these strategies were sensitive to the importance that assessors' assigned to different species. The 'Cost-Effective Resource Allocator' can accommodate input from up to eight assessors, and analyse a maximum of 50 management strategies for 30 species.

This paper deals with the experimental and theoretical studies of abnormal properties of terephthalic acid (TAC) and phthalic acid (PAC) crystals manifested in the H/D isotopic exchange. The widely utilized deuteration routine appeared to be insufficiently effective in the case of the h 6 -TAC isotopomer. In the case of the d 4 -TAC derivative the isotopic exchange process occurred noticeably more effectively. In contrast, both isotopomers of PAC, h 6 and d 4 , appeared much more susceptible for deuteration. A theoretical model was elaborated describing “long-distance” dynamical co-operative interactions involving hydrogen bonds in TAC and PAC crystals. The model assumes extremely strong dynamical co-operative interactions of hydrogen bonds from the adjacent (COOH) 2 cycles. This leads to an additional stabilization of h 6 –TAC molecular chains. The interaction energies affect the chemical equilibrium of the H/D isotopic exchange. The model predicts a differentiated influence of the H and D atoms linked to the aromatic rings on to the process. In this approach the totally-symmetric C H bond stretching vibrations and the proton stretching totally symmetric vibrations couple with the π -electronic motions. It was also shown that identical hydrogen isotope atoms, H or D, in whole TAC molecules, noticeably enlarge the energy of the dynamical co-operative interactions in the crystals, in contrast to the case of different hydrogen isotopes present in the carboxyl groups and linked to the aromatic rings. The “long-distance” dynamical co-operative interactions in PAC crystals were found of a minor importance due to the electronic properties of PAC molecules.

As with many islands, Christmas Island in the Indian Ocean has suffered severe biodiversity loss. Its terrestrial lizard fauna comprised five native species, of which four were endemic. These were abundant until at least the late 1970s, but four species declined rapidly thereafter and were last reported in the wild between 2009 and 2013. In response to the decline, a captive breeding programme was established in August 2009. This attempt came too late for the Christmas Island forest skink Emoia nativitatis, whose last known individual died in captivity in 2014, and for the non-endemic coastal skink Emoia atrocostata. However, two captive populations are now established for Lister's gecko Lepidodactylus listeri and the blue-tailed skink Cryptoblepharus egeriae. The conservation future for these two species is challenging: reintroduction will not be possible until the main threats are identified and controlled.

The present treatment shows that the lichen family Trypetheliaceae is an important component of lowland and montane tropical forests in Bolivia. A total of 75 species are currently recognized in Bolivia, of which 24 are new to science and a further 37 are reported for the first time from the country. The following species are described: Architrypethelium penuriixanthum Flakus & Aptroot sp. nov. that differs from A. hyalinum in the lack of lichexanthone in the thallus; Astrothelium amylosporum Flakus & Aptroot sp. nov. that differs from A. subdisjunctum in having 8-spored asci and amyloid ascospores; A. bullatum Flakus & Aptroot sp. nov. that differs from A. megaspermum in having a bullate thallus, a clear hamathecium, 8-spored asci and smaller amyloid ascospores; A. carrascoense Flakus, Kukwa & Aptroot sp. nov. that differs from A. meristosporum in having broader ascospores without distinctly thickened median septa, an unidentified xanthone as major substance, and mostly eccentric ostioles; A. elixii Flakus & Aptroot sp. nov. that differs from all other Astrothelium species in the presence of lichexanthone in the outer layer of thallus and pseudostromata and isohypocrellin inside the pseudostromata, and muriform ascospores; A. inspersotuberculosum Flakus & Aptroot sp. nov. that differs from A. tuberculosum in having an inspersed hamathecium; A. megaeneum Flakus & Aptroot sp. nov. that differs from A. croceum in having a thallus covered by parietin, and mostly fused ascomata with intermediate, fused to separated ostioles surrounded by a common ostiolar area; A. neodiplocarpum Flakus, Kukwa & Aptroot sp. nov. that differs from A. diplocarpum in the absence of medullary pigment and in the amyloid ascospores; A. nigrocacuminum Flakus, Kukwa & Aptroot sp. nov. that differs from A. megochroleucum in having fused, eccentric ostioles and black (UV−) tops of the pseudostromata; A. pallidoflavum Flakus & Aptroot sp. nov. that differs from A. cinnamomeum in having wider ascospores; A. pyrenuliforme Flakus & Aptroot sp. nov. that differs from A. ecuadoriensis ecuadoriense in having shorter ascospores and in the presence of pseudocyphellae; A. subscoria Flakus & Aptroot sp. nov. that differs from A. scoria in having non-aggregated ascomata; A. variabile Flakus & Aptroot sp. nov. that differs from A. ochroleucoides in the longer ascospores; Bathelium boliviense Flakus & Aptroot sp. nov. that differs from B. lineare in the presence of isohypocrellin inside the pseudostromata; B. flavostiolatum Flakus & Aptroot sp. nov. that differs from all other Bathelium species in the presence of lichexanthone near the ostioles (tops of pseudostromata UV+ yellow) and an orange (K+ carmine red) pigment inside the pseudostromata, the absence of lichexanthone in the thallus, an inspersed hamathecium, and 13–17-septate ascospores; B. inspersomastoideum Flakus & Aptroot sp. nov. that differs from B. mastoideum in having an inspersed hamathecium; B. mirabile Flakus, Kukwa & Aptroot sp. nov. that differs from other Bathelium species in the pseudostromata containing isohypocrellin inside and parietin outside; B. pruinosum Flakus, Kukwa & Aptroot sp. nov. that differs from Astrothelium ochroleucoides in having 8-spored asci, shorter ascospores, an inspersed hamathecium, and an unidentified anthraquinone (orange pigment K+ carmine red) inside the pseudostromata; Constrictolumina chiquitana Flakus, Kukwa & Aptroot sp. nov. that differs from other known Constrictolumina species in having brown and 1-septate to submuriform ascospores; Dictyomeridium lueckingii Flakus & Aptroot sp. nov. that differs from D. proponens in having smaller and less septate ascospores; Polymeridium xanthoexcentricum Flakus & Aptroot sp. nov. that differs from P. alboflavescens in having mostly eccentric ostioles; Pseudopyrenula flavosuperans Flakus & Aptroot sp. nov. that differs from P. superans in having a hamathecium inspersed with yellow oil globules; Trypethelium astroideum Flakus & Aptroot sp. nov. that differs from T. subeluteriae in having K+ carmine red pseudostromata containing parietin inside and black tops with an additional unidentified anthraquinone (rust-red pigment K+ purple, UV−) on the outside, partly fused ostioles, and larger ascospores; and T. xanthoplatystomum Flakus & Aptroot sp. nov. that differs from T. platystomum in the presence of lichexanthone in the thallus.
