Lakes in Europe are subject to multiple anthropogenic pressures, such as eutrophication, habitat degradation and introduction of alien species, which are frequently inter-related. Therefore, effective assessment methods addressing multiple pressures are needed. In addition, these systems have to be harmonised (i.e. intercalibrated) to achieve common management objectives across Europe. Assessments of fish communities inform environmental policies on ecological conditions integrating the impacts of multiple pressures...

Plants with animal-dispersed fruits seem to overcome the barriers that limit their spread into new habitats more easily than other invasive plants and, at the same time, they pose special difficulties for containment, control or eradication. The effects of animals on plant propagules can be very diverse, with positive, neutral or negative consequences for germination and recruitment. Moreover, the environmental conditions where the seeds are deposited and where the post-dispersal processes take place can be crucial for their fate...

BACKGROUND: Haynaldia villosa (L.) Schur (syn. Dasypyrum villosum L. Candargy, 2n = 14, genome VV) is the tertiary gene pool of wheat, and thus a potential resource of genes for wheat improvement. Among other, wheat yellow mosaic (WYM) resistance gene Wss1 and a take-all resistance gene were identified on the short arm of chromosome 4 V (4VS) of H. villosa. We had obtained introgressions on 4VS chromosome arm, with the objective of utilizing the target genes. However, monitoring these introgressions has been a daunting task because of inadequate knowledge as to H...

In 1875 Bahia, medicine and evolutionism were used by the physician, journalist, and republican militant Domingos Guedes Cabral as ideological weapons to propose a radical program of social reforms in Brazil in the areas of education, marriage control, medical care to the alienated, changes in the penal system, etc., all of which were based on the scientific knowledge of that time. Among the social ideas of Guedes Cabral, the question of race will be the main focus of this analysis. In this sense, Domingos Guedes Cabral is a particularly significant example for understanding the initial steps in the peculiar alliance between evolutionism, medicine, and scientific racism in Brazil since the 1870s, when Darwinism first arrived in the country...

Background There is anecdotal clinical evidence that transgender people use the online world - such as forums and online video gaming - for the purpose of experiencing their gender identity in a safe, non-threatening, non-alienating, non-stigmatizing, and non-critical environment. Aims To describe gaming behavior, degree of problematic gaming behavior and associated factors with problematic gaming in a comparatively large group of transgender people accessing transgender health services. Methods Every individual referred to a national transgender health service in the United Kingdom during a 12-month period was invited to complete a series of questionnaires to measure gaming behavior, interpersonal functioning, severity of autistic features, and anxiety and depressive symptoms...

Although research on human-mediated exchanges of species has substantially intensified during the last centuries, we know surprisingly little about temporal dynamics of alien species accumulations across regions and taxa. Using a novel database of 45,813 first records of 16,926 established alien species, we show that the annual rate of first records worldwide has increased during the last 200 years, with 37% of all first records reported most recently (1970-2014). Inter-continental and inter-taxonomic variation can be largely attributed to the diaspora of European settlers in the nineteenth century and to the acceleration in trade in the twentieth century...

Adenosine triphosphate (ATP), the major energy currency of the cell, exists in solution mostly as ATP-Mg. Recent experiments suggest that Mg(2+) interacts with the highly charged ATP triphosphate group and Li(+) can co-bind with the native Mg(2+) to form ATP-Mg-Li and modulate the neuronal purine receptor response. However, it is unclear how the negatively charged ATP triphosphate group binds Mg(2+) and Li(+) (i.e. which phosphate group(s) bind Mg(2+)/Li(+)) and how the ATP solution conformation depends on the type of metal cation and the metal-binding mode...

Science and technology studies (STS) and critical cartography are both asking questions about the ontological fixity of maps and other scientific objects. This paper examines how a group of NASA computer scientists who call themselves The Mapmakers conceptualizes and creates maps in service of different commitments. The maps under construction are those of alien Mars, produced through partnerships that NASA has established with Google and Microsoft. With the goal of bringing an experience of Mars to as many people as possible, these maps influence how we imagine our neighbouring planet...

The socialist factory, as the 'incubator' of the new socialist (wo)man, is a productive entry point for the study of socialist modernization and its contradictions. By outlining some theoretical and methodological insights gathered through field-research in factories in former Yugoslavia, we seek to connect the state of labour history in the Balkans to recent breakthroughs made by labour historians of other socialist countries. The first part of this article sketches some of the specificities of the Yugoslav self-managed factory and its heterogeneous workforce...

Marine coastal ecosystems are affected by a vast array of human-induced disturbances and stresses, which are often capable of overwhelming the effects of natural changes. Despite the conceptual and practical difficulty in differentiating between disturbance and stress, which are often used interchangeably, the two terms bear different ecological meanings. Both are external agents, but the former causes mortality or physical damage (subtraction of biomass), whereas the latter causes physiological alteration (reduction in productivity)...

Context: Empathy, teamwork, and lifelong learning are described as key elements of professionalism. The first recipients of their benefits are professionals themselves. Paradoxically, scarce studies have reported association between professionalism and occupational well-being. The main purpose of this study was to characterize the influence that empathy, teamwork, and lifelong learning, play in the occupational well-being of physicians and nurses working in Latin American healthcare institutions. Materials and Methods: The Jefferson Scale of Empathy, the Jefferson Scale of Attitudes toward Physician-Nurse Collaboration, the Jefferson Scale of Physicians Lifelong Learning, and the Scale of Collateral Effects (somatization, exhaustion, and work alienation), were administered to 522 physicians and nurses working in institutions of Mexico, Colombia, Ecuador, and Argentina...

Leymus mollis (Trin.) Pilger (2n = 4x = 28, NsNsXmXm) possesses a number of valuable genes against biotic and abiotic stress, which could be transferred into common wheat background for wheat improvement. In the present study, we determined the karyotypic constitution of a wheat-L. mollis double disomic addition line M11003-4-4-1-1 selected from the F5 progeny of a stable wheat-L. mollis derivative M39 (2n = 56) × Triticum aestivum cv. 7182, by morphological and cytogenetic identification, GISH (genomic in situ hybridization), FISH (fluorescent in situ hybridization), molecular markers analysis and stripe rust resistance evaluation...

In this work, the meiotic behavior, chromosome constitution, and stripe rust resistance of the F5 derivatives from wheat-Th. intermedium-P. huashanica trigeneric hybrid were studied. Cytological analysis indicated that the chromosome number of F5 progenies ranged from 42 to 50. The mean meiotic configuration of F5 lines was 1.28 univalents, 21.74 bivalents, 0.04 trivalents, and 0.02 tetravalents per pollen mother cell (PMC). Among the lines with 2n = 42, the average pairing configuration was 0.05 I + 19.91 II (ring) + 1...

A major bottleneck to introgressive hybridization is the lack of genome collinearity between the donor (alien) genome and the recipient crop genome. Structural differences between the homeologs may create unbalanced segregation of chromosomes or cause linkage drag. To assess large-scale collinearity between potato and two of its wild relatives (Solanum commersonii and Solanum chacoense), we used BAC-FISH mapping of sequences with known positions on the RH potato map. BAC probes could successfully be hybridized to the S...

Trait-based approaches are widely used in community ecology and invasion biology to unravel underlying mechanisms of vegetation dynamics. Although fundamental trade-offs between specific traits and invasibility are well described among terrestrial plants, little is known about their role and function in aquatic plant species. In this study, we examine the functional differences of aquatic alien and native plants stating that alien and native species differ in selected leaf traits. Our investigation is based on 60 taxa (21 alien and 39 native) collected from 22 freshwater units of Hungarian and Italian lowlands and highlands...

BACKGROUND: Low- and middle-income countries in Africa have the highest rates of stillbirths in the world today: as such, the stories of the grief of these women who have had a stillbirth in these settings need to be told and the silence on stillbirth needs to be broken. In an attempt to fill this gap, the aim of this study was to describe the experiences of Muslim Somali mothers who have lost their babies at birth. METHOD: Qualitative interviews with ten Somali women one to six months after they experienced a stillbirth...

Emotional labor has been an area of burgeoning research interest in occupational health psychology in recent years. Emotional labor was conceptualized in the early 1980s by sociologist Arlie Hochschild (1983) as occupational requirements that alienate workers from their emotions. Almost 2 decades later, a model was published in Journal of Occupational Health Psychology (JOHP) that viewed emotional labor through a psychological lens, as emotion regulation strategies that differentially relate to performance and wellbeing...

BACKGROUND: While patients with cancer commonly experience bodily pain, their perceptions of this pain may differ. Continually experiencing pain elicits a sense of helplessness and pessimism in these patients and exacerbates their perception of interpersonal alienation, which may cause the demoralization syndrome. In Taiwan, the rate of demoralization among patients with cancer is substantially higher than that in other countries. PURPOSE: The meaning of cancer pain is used as the mediating variable to investigate the relationship between the pain that is experienced by patients with cancer and their demoralization...

Tandem repeats are often associated with important chromosomal landmarks, such as centromeres, telomeres, subtelomeric, and other heterochromatic regions, and can be good candidates for molecular cytogenetic markers. Tandem repeats present in many plant species demonstrate dramatic differences in unit length, proportion in the genome, and chromosomal organization. Members of genus Allium with their large genomes represent a challenging task for current genetics. Using the next generation sequencing data, molecular, and cytogenetic methods, we discovered two tandemly organized repeats in the Allium fistulosum genome (2n = 2C = 16), HAT58 and CAT36...
