Drivers of flower visit and resource sharing between the honeybee and native bees in Neotropical coastal sand dunes.

The honeybee (Apis mellifera) is one of the most important pollinator species because it can gather resources from a vast variety of plant species, including both natives and introduced, across its geographical distribution. Although A. mellifera interacts with a large diversity of plants and shares resources with other pollinators, there are some plant species with which it interacts more frequently than others. Here, we evaluated the plant traits (i.e., plant length, abundance of bloomed individuals, number of open flowers, and stamen length) that would affect the honeybee visit frequencies to the flowers in a coastal environment in the Gulf of Mexico. Moreover, we evaluated which native bee species (and their body size) overlap floral resource with A. mellifera. We registered 998 plant-bee interactions between 35 plant species and 47 bee species. We observed that plant species with low height and with high abundances of bloomed individuals are positively related to a high frequency of visits by A. mellifera. Moreover, we found that A. mellifera tends to share a higher number of plant species with other bee species with a similar or smaller body size than with bigger species, which makes them a competitor for the resource with honeybees. Our results highlight that the impacts of A. mellifera on plants and native bees could be anticipated based on its individual's characteristics (i.e., plant height and abundance of bloomed individuals) and body size, respectively.

Cultural adaptation and validation of the caring behaviors assessment tool into Spanish.

BACKGROUND: The aim of the research was to translate, culturally adapt and validate the Caring Behaviors Assessment (CBA) tool in Spain, ensuring its appropriateness in the Spanish cultural context. METHODS: Three-phase cross-cultural adaptation and validation study. Phase 1 involved the transculturation process, which included translation of the CBA tool from English to Spanish, back-translation, and refinement of the translated tool based on pilot testing and linguistic and cultural adjustments. Phase 2 involved training research assistants to ensure standardized administration of the instrument. Phase 3 involved administering the transculturally-adapted tool to a non-probabilistic sample of 402 adults who had been hospitalized within the previous 6 months. Statistical analyses were conducted to assess the consistency of the item-scale, demographic differences, validity of the tool, and the importance of various caring behaviors within the Spanish cultural context. R statistical software version 4.3.3 and psych package version 2.4.1 were used for statistical analyses. RESULTS: The overall internal consistency of the CBA tool was high, indicating its reliability for assessing caring behaviors. The subscales within the instrument also demonstrated high internal consistency. Descriptive analysis revealed that Spanish participants prioritized technical and cognitive aspects of care over emotional and existential dimensions. CONCLUSIONS: The new version of the tool proved to be valid, reliable and culturally situated, which will facilitate the provision of objective and reliable data on patients beliefs about what is essential in terms of care behaviors in Spain.

Nursing is not like organised crime: A theoretically informed commentary.

AIM: This article aims to contest misrepresentations and distortions of sociological writings on the nursing profession. BACKGROUND: During the latest ICN congress in Montreal, it has been suggested that professions, and the nursing profession for that matter, are thought of by sociologists in a similar way as organised crime, meaning that it is like a 'money sponge' sucking resources out of society, without however giving anything in return. Allegedly, there would be a distinct branch of sociology depicting the professions in this light. DISCUSSION: By sketching out relevant sociological ideas, including the sociology of nursing, I explain that there is no tradition portraying the professions as mafias. I demonstrate that while both the professions and organised crime are socially organised, they are radically different in legitimacy. The caring professions are themselves different in ethos from the classic professions, all the more so from criminal organisations. A distinct stream of research in sociology has been devoted to nursing, without however suggesting such an analogy. CONCLUSION: I lament that attendees to the ICN congress were indeed given an inaccurate representation of sociological thinking. Sociologists addressing nursing as a profession tend to highlight processes of emancipation, autonomy, vindication and social justice, as care work is essential to the broader socioeconomic order. IMPLICATIONS FOR NURSING POLICY: While nursing as a profession is socially organised, the power devices and tactics it deploys in the sociopolitical arena are characterised by their legitimacy. Unlike organised crime, nursing policymaking is situated within a framework of lawfulness, fairness and transparency.

Reliability of OMERACT ultrasound elementary lesions in gout: results from a multicenter exercise.

The aim of this study was to evaluate the reliability of the outcome measures in rheumatology (OMERACT) definitions for ultrasound (US) elementary lesions in gout through an image reading exercise. Images from patients with gout (static images and videos) were collected. As an initial step, we carried out a image reading exercise within the experts of the Pan-American League of Associations for Rheumatology (PANLAR) US Study Group (n = 16). The following step consisted in a web-based exercise with the participation of larger number of sonographers (n = 63) from different centers. Images were rated evaluating the presence/absence of any US elementary lesion. Inter- and intra-reader reliabilities were analyzed using kappa coefficients. Participants were stratified according to their level of experience. In the first exercise, inter-reader kappa values were 0.45 for aggregates, 0.57 for tophus, 0.69 for erosions, and 0.90 for double contour (DC). Intra-reader kappa values were 0.86, 0.76, 0.80, and 0.90, respectively. The web-based exercise showed inter-reader kappa values for aggregates, tophus, erosions, and DC of 0.42, 0.49, 0.69, and 0.79, respectively. The intra-reader kappa values were 0.62, 0.69, 0.77, and 0.85, respectively. Reliability was not influenced by the sonographer's level of experience. The reliability of the new OMERACT US definitions for elementary lesions in gout ranged from moderate to excellent, depending on the type of lesion.

Evidence of presence and replication of honey bee viruses among wild bee pollinators in subtropical environments.

We determined the presence of six viruses in different bee species collected in subtropical environments. Deformed wing virus (DWV) and black queen cell virus (BQCV) were detected in >90% of honey bee samples and in 50-100% of four stingless bee, two bumble bee and one solitary bee species. Additionally, minus DWV and BQCV RNA strands were detected, indicating that the viruses replicate in several hosts. This is the first report of honey bee viruses replicating in six wild bee species in the tropics. If pathogenic to them, viral infections could result in negative impacts in agricultural and unmanaged ecosystems.

The system of nursing in Chile: Insights from a systems theory perspective.

Nursing is possible owing to a series of intricate systemic relations. Building on an established tradition of sociological research, we critically analysed the nursing profession in Chile, with an emphasis on its education system, in the light of social systems theory. The paper's aim was to explore basic characteristics of nursing education as a system, so as to outline its current evolution. Drawing on recent developments in nursing, we applied an empirical framework to identify and discuss functionally differentiated systems that are relevant to nursing and observe communications between them. We found that the dynamics of nursing as a whole develop from communications with closely related systems, including the nursing profession and the education system more broadly. While the discipline (as a system of representations) strives to control the profession (as an applied occupational field), the necessities of practicing nurses imply other forces mediating the making of the profession, a process framed by market dynamics in education and health.

Twenty years of management of care in Chile: what we know, what we do not know, what is yet to come. An analysis of arguments.

For over 20 years, the notion of 'management of care' has been foregrounded as key in the jurisdiction of the nursing profession, with the aim of detaching itself from the wider medical umbrella. A number of voices have advocated such centrality. These include juridical, academic and occupational perspectives. Critical stances, although peripheral, have also been voiced. These have been received, at best, with a 'polite silence' in mainstream circles.By looking at the arguments surrounding the 'management of care' circulated in these two decades, this article reports the various forms of discursive practice that participate in the political process of autonomy building. Particularly, we focus on the validity of the arguments as well as the cohesion across arguments within the knowledge system. In doing so, we evaluate its main premises and foundations, the reach of the conceptualisation and its disjointed, differing and incomplete bases. Similarly, we used an inferential technique for the reconstruction of omitted and unexpressed assertions.The article introduces an approach of the humanities that is seldom seen in healthcare. It also proposes a research agenda in regard to management of care for the upcoming decades.

Cold Interests, Hot Conflicts: How a Professional Association Responded to a Change in Political Regimes.

In South America, the 1970s began with ardent sociopolitical crises leading to a wave of repressive military regimes. In Chile, most professional bodies suffered profound structural and functional modifications resulting from internal political polarization as well as state intervention. Nurses saw the same fate befall them, which created both a historical blackout and abrupt changes in power dynamics. Given the prominence of this process in the reconfiguration of modern nursing's identity, this article traces the association's political process during the short-lived 1970s Marxist-inspired government and the response of nurses collectively to the rapid shift into a repressive regime leading to a profound internal crisis and an identity break-up within nursing. By using archival sources and oral testimonies1 of 1970s and 1980s nurses, we reconstruct a historical account of a key period in the history of the country that for the nurses meant a progression of discord and division along with a self-imposed silence on the past. In so doing, the article adds to a growing literature on the participation of women in political life.

Dusting off the looking-glass: A historical analysis of the development of a nursing identity in Chile.

Histories of nursing that disregard their linkage to broader historical movements often lead to historically detached versions of nursing identity that omit the perspective of their sources and the ideas of their time. Drawing on materials retrieved through a multilayered research strategy comprising internal and external sources, this article examines the development of a nursing identity in Chile during the period starting in the 1950s through the early 2000s. We analysed the sociopolitical contexts in which the nursing profession grew, the changing direction of its role and how the nursing identity transformed itself. Through the use of historical sources and oral testimonies, we aim to give a nuanced account of how the history of public health and that of the country more broadly changed the object of identification of nurses, creating only relatively recently a sense of nursing community. Processes of identification, fragmentation and integration are highlighted, which challenge usual notions of history as a linear process.

Cultural adaptation and validation of the Caring Behaviors Assessment tool in Chile.

This study reports the process of cultural adaptation of the Caring Behaviors Assessment tool for the Spanish language, and determine its validity and reliability. We used a mixed-methods approach with a sample of adult participants after translation and adjustment, correlations and multiple regressions were used to explain differences in perception. Internal consistency and reliability were determined by using Cronbach's alpha. While slight modifications to syntax, language, and the interval scale were necessary to enable better comprehension, all items had high average scores as did the seven subscales. Additionally, similarities with previous literature suggest cultural suitability of the instrument across countries. This version of the tool was judged to be valid and reliable, and will facilitate care measurability and theoretical sensitivity in Spanish-speaking countries.

Exploring historical conflicts between midwives and nurses: a perspective from Chile.

This article explores issues of historical disputes between nurses and midwives based in Chile. The interaction of these two professions in that country has become an arena of competition which leads to conflicts periodically, such as those related to the ownership of the care of new-borns, and that of projects aimed at relieving nurse shortages by enhancing midwives' nursing skills. Specifically, this article aims to build on historical and contemporary resources analysed from a sociological perspective, and present comparatively a rationale concerning nursing/midwifery jurisdictional conflicts through a social history account. Our analysis suggests that nurses/midwives interaction has been shaped by social-historical transformations and the continuous evolution of the healthcare system as a whole, resulting in a race towards technologisation. These interprofessional conflicts can be explained partly by mechanisms of boundary expansion within an organisational/interpretive domain, as well as varying degrees of medicalisation; and partly by a competition possibly originating from a middle-class consciousness. An eventual merger of the two professions might lead to the enhancement of the political power of the caring professions and integrated care.

Prompting professional prerogatives: new insights to reopen an old debate about nursing.

A profession is defined by neither a set of structural qualities nor a description idiosyncratic to a single culture. Rather, a profession detects problems in an area of work, intellectualizes that work, and offers solutions, developing a logic of competition with coexisting occupations. The best that structural explanations can offer to nursing is rigid, unmovable definitions such as "a semi-profession," whereas the ecological theory of the professions regards the continuous interplay among occupations cohabiting in an interacting system as the fundamental process of gaining or losing professional status. In this theoretically driven article we draw upon the notion of "social ecology of nursing" as a vector of development, arguing that nursing's professional status lies in its ability to adapt to "landscape" transformations and to protect its jurisdiction from competitors, equating fully established professions. In discussing the application of this theory, we invite readers to reopen a debate about the professional nature of nursing, considering cross-national versions of nursing for more comprehensive definitions of the profession.

Stingless bee classification and biology (Hymenoptera, Apidae): a review, with an updated key to genera and subgenera.

Stingless bees (Meliponini) are a ubiquitous and diverse element of the pantropical melittofauna, and have significant cultural and economic importance. This review outlines their diversity, and provides identification keys based on external morphology, brief accounts for each of the recognized genera, and an updated checklist of all living and fossil species. In total there are currently 605 described extant species in 45 extant genera, and a further 18 extinct species in nine genera, seven of which are extinct. A new fossil genus, Adactylurina Engel, gen. nov., is also described for a species in Miocene amber from Ethiopia. In addition to the systematic review, the biology of stingless bees is summarized with an emphasis on aspects related to their nesting biology and architecture.

THE NEOTROPICAL SPECIES OF SMALL CARPENTER BEES OF THE SUBGENUS CERATINA (ZADONTOMERUS) ASHMEAD, 1899 (HYMENOPTERA: APIDAE).

The Neotropical species of the subgenus Ceratina (Zadontomerus) Ashmead are revised. We recognize seven new species, giving a total of 10 species for the region: Ceratina (Zadontomerus) capitosa Smith, C. (Z.) ignara Cresson, C. (Z.) nautlana Cockerell, C. (Z.) kopili new species, C. (Z.) basaltica new species, C. sapphira new species, C. (Z.) indigovirens new species, C. (Z.) rehanae new species, C. (Z.) raquelitae new species, and C. (Z.) tepetlana new species. We propose the following synonymies: C. abdominalis Smith, C. tehuacana Strand, and C. parignara Cockerell under C. (Z.) ignara; and C. bakeri Smith and C. nigriventris Friese under C. (Z.) nautlana. Also, we describe the previously unknown male of C. capitosa, and provide a key to the species, diagnoses, descriptions and illustrations of the new species.

Balloon Kyphoplasty vs Vertebroplasty: A Systematic Review of Height Restoration in Osteoporotic Vertebral Compression Fractures.

Purpose of Review: This systematic review comprehensively compared balloon kyphoplasty and vertebroplasty with respect to height restoration and pain relief. Recent Findings: PRISMA guidelines were utilized to compare balloon kyphoplasty and vertebroplasty, focusing on the primary outcome of height restoration and the secondary outcomes of pain relief and functionality. A total of 33 randomized controlled trials were included; 20 reviewed balloon kyphoplasty, 7 reviewed vertebroplasty, and 6 compared vertebroplasty to balloon kyphoplasty. Both treatments restored some vertebral body height and showed benefits in pain reduction and improved patient-reported functionality. Summary: Balloon kyphoplasty and vertebroplasty are effective treatments for vertebral compression fractures and this review suggests that balloon kyphoplasty may be favored for vertebral height restoration. Further studies are needed to conclude whether balloon kyphoplasty or vertebroplasty is superior for alleviating pain.

Making science international: Chilean journals and communities in the world of science.

Drawing on the evolution of socio-geographical imaginaries of scholarly journals published in Chile, this article provides a picture of the socio-historical trajectories of internationalization of scholarly journals and communities in that part of the (semi-)periphery of science. In order to break with the presentism of many contemporary discussions, the analysis covers a relatively long period of time, from the end of the nineteenth century until the first decades of the twenty-first century. However, based on an inductive analysis of the journals, the article particularly focuses on the rise of nationalist and regionalist orientations in the late nineteenth and early twentieth centuries and the intensification of the pressures for internationalization in more recent decades. Building on the findings, the article concludes highlighting key elements and making some general observations on the internationalization processes in the semi-periphery of science.

Two new species of nocturnal bees of the genus Megalopta (Hymenoptera: Halictidae) with keys to species.

Megalopta Smith, 1853, is a Neotropical genus of nocturnal or crepuscular bees. Two subgenera are recognized with most of its nearly 30 species placed in the nominate subgenus. Species of Megalopta s. str. are more commonly collected than species of Noctoraptor Engel et al. 1997, all presumably parasites of Megalopta s. str. Two new species of Megalopta are described here: M. (Megalopta) tetewana, n. sp., from Mexico and M. (Noctoraptor) huaoranii, n. sp., from Ecuador. Identification keys to the Central American species of Megalopta s. str. and the species of the parasitic subgenus Noctoraptor are presented.
