This research deals with the problem regarding the optimal siting and sizing of distribution static compensators (D-STATCOMs) via the application of a master–slave optimization technique. The master stage determines the nodes where the D-STATCOMs must be located and their nominal rates by applying the generalized normal distribution optimizer (GNDO) with a discrete–continuous codification. In the slave stage, the successive approximations power flow method is implemented in order to establish the technical feasibility of the solution provided by the master stage, i.e., voltage regulation and device capabilities, among other features. The main goal of the proposed master–slave optimizer is to minimize the expected annual operating costs of the distribution grid, which includes the energy loss and investment costs of the D-STATCOMs. With the purpose of improving the effectiveness of reactive power compensation during the daily operation of the distribution grid, an optimal reactive power flow (ORPF) approach is used that considers the nodes where D-STATCOMs are located as inputs in order to obtain their daily expected dynamical behavior with regard to reactive power injection to obtain additional net profits. The GNDO approach and the power flow method are implemented in the MATLAB programming environment, and the ORPF approach is implemented in the GAMS software using a test feeder comprising 33 nodes with both radial and meshed configurations. A complete comparative analysis with the Salp Swarm Algorithm is presented in order to demonstrate the effectiveness of the proposed two-stage optimization approach in the fixed operation scenario regarding the final objective function values. In addition, different tests considering the possibility of hourly power injection using D-STATCOMs through the ORPF solution demonstrate that additional gains can be obtained in the expected annual operative costs of the grid.

Each culture has unique health care related values, habits, perceptions, expectations, norms, etc., that makes cultural competence an important attribute to be developed by healthcare professionals, to ensure they provide effective treatment. Intercultural sensitivity (IS) is the affective dimension of cultural competence. The objective of this study is to explore the self-perceived level of IS in first and last year students of three health sciences professions (i.e., Dentistry, Medicine, and Nursing) at the Universidad de la Frontera, Temuco, Chile. This study adopted a cross-sectional design and a group comparison (e.g., year of study). 312 students completed the Intercultural Sensitivity Scale (ISS). Findings showed that overall ISS scores ranged from 1.83 to 4.94, with a mean score of 4.11 (s.d. 0.43). Group comparison between first and final year students showed statistically significant differences (4.18 vs. 4.00; p  < 0.001). Medical and nursing students had a significantly higher overall mean IS score compared to dental students (4.21 and 4.16, respectively vs. 4.02; p  < 0.01). There were also significant differences between three factors (interaction engagement; interaction confidence; and interaction enjoyment) by healthcare profession. These findings allow for discussion of the need for explicit incorporation and development of cultural competence in on health care professional curricula. Longitudinal research is needed to explore how IS changes over time, along with generating qualitative data from the student populations IS experiences and exposure.

Background Cultural competence development in the formative process of healthcare professionals is crucial for the provision of culturally appropriate health care. This educational issue is highly relevant in the growing multicultural composition of southern Chile. The objective of this study was to examine how the healthcare professions curricula at the Universidad de La Frontera, in La Araucanía Region, prepares future professionals to respond to patients' cultural needs. Method A sequential transformative mixed methods design composed of two phases was carried out. Phase 1 reviewed all printed material and documentation to explore content that developed cross-cultural skills and competencies in the curricula. In Phase 2 semi-structured interviews were conducted with academics with responsibilities for the development of the curriculum in each career, to detect how academics envisage the incorporation of cultural competence in the curricula. Results Regarding curricular contents, findings indicated that the healthcare professions curricula at The Universidad de La Frontera have similar approaches to the inclusion of CCT in subjects’ syllabuses, with inclusion of the different CCT, particularly in the Dental and Medical curricula. However, this coverage showed significant variations in the undergraduate healthcare curricula. The analysis revealed that themes around the Ethics and human values for professional practice; the Psychosocial and cultural determinants of health; the Relationship health-family-community, and to a lesser extent, the Clinician-patient relationship were well covered in the courses. On the other hand, Inequalities in health was the theme with the least contact time in all three courses. Academics called for a better organisation of the inclusion of CCT in the curricula. They also highlighted the challenges of maintaining the dominant paradigm underlying healthcare models, practices, and orientations within the academic staff and health discipline. Conclusion Curricula contents findings indicate that the healthcare professions curricula at Universidad de La Frontera have similar approaches to the inclusion of CCT in subjects’ syllabuses. However, its depth of coverage allows for improvements. The systematization of CCT and teaching–learning methodologies in healthcare professions curricula is necessary to develop formative processes that allow future professionals to be aware of and respectful with patients’ cultural characteristics and needs.

Objective The Caribbean is an important global biodiversity hotspot. Adaptive radiations there lead to many speciation events within a limited period and hence are particularly prominent biodiversity generators. A prime example are freshwater fish of the genus Limia , endemic to the Greater Antilles. Within Hispaniola, nine species have been described from a single isolated site, Lake Miragoâne, pointing towards extraordinary sympatric speciation. This study examines the evolutionary history of the Limia species in Lake Miragoâne, relative to their congeners throughout the Caribbean. Results For 12 Limia species, we obtained almost complete sequences of the mitochondrial cytochrome b gene, a well-established marker for lower-level taxonomic relationships. We included sequences of six further Limia species from GenBank (total N  = 18 species). Our phylogenies are in concordance with other published phylogenies of Limia . There is strong support that the species found in Lake Miragoâne in Haiti are monophyletic, confirming a recent local radiation. Within Lake Miragoâne, speciation is likely extremely recent, leading to incomplete lineage sorting in the mtDNA. Future studies using multiple unlinked genetic markers are needed to disentangle the relationships within the Lake Miragoâne clade.

The aim of this study was to evaluate the relationships between self-esteem, social support, negative and positive emotions, resilience, positive religious beliefs and levels of dependency in low stratum older adults in the Colombian Atlantic coast. A non-experimental design of descriptive correlational and cross-sectional type was used for this study. The sample consisted of 115 non-institutionalized adults over 60 years of age from the low stratum of the Department of Córdoba, Colombia. The following scales were used as measurement instruments: CD-RISC 10 for resilience, HADS for anxiety and depression, DUKE-UNC for social support, RSE for self-esteem and R-COPE for positive religious coping. Results at the correlational level showed on the one hand that resilience and self-esteem had a positive correlation with social support and positive religious beliefs and on the other hand negative correlations between anxiety and depression with self-esteem and social support. In conclusion, in this sample of older adults there were good levels of positive emotions, low levels of negative emotions and low levels of positive emotions. El objetivo del presente estudio fue evaluar las relaciones entre la autoestima, el apoyo social, las emociones negativas y positivas, la resiliencia, las creencias religiosas positivas y los niveles de dependencia en adultos mayores de estrato bajo en la Costa Atlántica colombiana. Para este estudio se utilizó un diseño no experimental de tipo descriptivo correlacional y de corte transversal. La muestra estuvo conformada por 115 adultos mayores de 60 años de estrato bajo del departamento de Córdoba, Colombia, no institucionalizados. Como instrumentos de medida se emplearon las escalas CD-RISC 10 de resiliencia, HADS de ansiedad y depresión, DUKE-UNC de apoyo social, RSE de autoestima y R-COPE de afrontamiento religioso positivo. Resultados a nivel de correlacional se encontró, por un lado, que la resiliencia y la autoestima tuvieron una correlación positiva con el apoyo social y las creencias religiosas positivas y, por otro, correlaciones negativas entre ansiedad y depresión con autoestima y apoyo social. En conclusión, esta muestra de adultos mayores de estrato socioeconómico bajo de la ciudad de Montería presentó niveles elevados de emociones positivas y bajos niveles de emociones negativas.

In the context of a pandemic, the rapid development of clinical practice guidelines (CPGs) is critical to guide dental staff towards the safe provision of dental care; detailed knowledge of the recommendations will help to achieve the intended results. We carried out a systematic review of the recommendations in clinical practice guidelines (CPGs) on the provision of dental care issued during the first year of the COVID-19 pandemic. A systematic database search was performed in MEDLINE, EMBASE, LILACS, Epistemonikos, and Trip databases to identify documents with recommendations intended to minimize the risk of COVID-19 transmission during dental care. The selection process and data extraction were carried out by two researchers independently. The majority of CPGs recommended the use of rubber dam, high-volume evacuator, mouthwash prior to dental care, four-handed work, and mechanical barriers. The use of aerosol-generating equipment should be avoided whenever possible. In aerosol-generating procedures, the use of a N95 respirator (or similar) is recommended, in addition to a face protector, an impermeable disposable apron/gown, a cap, and gloves. The CPGs developed during the first year of the pandemic offer recommendations which guide dental staff in providing safe dental care, minimizing exposure to SARS-CoV-2 and reducing the risk of COVID-19 infection in the clinical environment. Such recommendations must, however, be updated as new evidence arises.

El rol del mediador se ha convertido en una pieza fundamental para cualquier tipología de museos y de sus visitantes. Esta figura, que ha superado el papel tradicional del guía, se erige como una de las más prometedoras y necesarias en museos de todas las tipologías. Este artículo presenta una encuesta realizada en el Museo Interactivo de Economía (MIDE) en Ciudad de México (México). La muestra recogida es de 93 cuestionarios aplicados a los mediadores del museo, jóvenes universitarios entre 20 y 30 años de edad. Los datos recogidos se codificaron a través de Excel, y entre otras conclusiones, el análisis indica que el 71% de los mediadores asistió a la formación ofrecida por el centro, el 84,9% considera que la ciencia y la tecnología son beneficiosas para la humanidad. La encuesta dio a conocer otros resultados como que los mediadores se consideran a sí mismos un puente entre el museo y el público; que las exposiciones guiadas y las explicaciones informales son dos de los formatos más utilizados en la mediación, y que los adolescentes y el público escolar son los visitantes que más atienden en sus labores cotidianas.

Os mediadores que atuam em museus na interseção entre os aparatos, os objetos e as exposições do museu com o público visitante são profissionais que possuem atribuições e perfis profissionais diversos. Neste estudo, mapeamos quem são os mediadores de espaços científicos e culturais do México e suas visões sobre o papel da mediação. A coleta de dados ocorreu por meio de um questionário on-line, respondido por 179 pessoas provenientes de 18 espaços científicos e culturais que se distribuem por dez estados da República Mexicana. Entre os respondentes, há um número maior de mulheres (126; 70,4%) e jovens entre 20 e 24 anos (108; 60,3%), com formação em licenciatura (122; 68,2%) ou com ensino médio completo (49; 27,3%). A maioria (157; 87,7%) atua há menos de dois anos na área, cumprindo jornadas de trabalho de até 20 horas semanais e recebendo bolsas de auxílio financeiro. Para os mediadores mexicanos que participaram deste estudo, suas ações não devem se limitar a explicação de conceitos; a maioria deles expressou considerar imprescindível que um bom mediador associe os conteúdos do museu com a vida cotidiana (135; 75,4%) e faça perguntas que provoquem reflexão (121; 67,6%). A mediação parece ser vista como uma atividade temporária, com um vínculo de curto prazo com as instituições mexicanas. Acreditamos que nosso estudo trará informações valiosas sobre os profissionais que atuam na mediação nos museus e centros de ciência do México, ajudando a fortalecer iniciativas de formação e manutenção desses atores sociais na profissão. 

Wikipedia is one of the most widely used information sources in the world. Although one of the guiding pillars of this digital platform is ensuring access to the diversity of human knowledge from a neutral point of view, there is a clear and persistent gender bias in terms of content about or written by women. Through semi-structured interviews with current and former women editors, our research offers a closer look at the different factors that influence editing practices on the Spanish Wikipedia: the educational and social contexts that prompt women to start or stop editing; their perceptions of the treatment of gender equality in the encyclopedia; and their feelings about taking part in the creation of content in an environment where they find themselves in a minority. Self-organized events known as edit-a-thons (in Spanish, Wikiquedadas), where women meet to discuss and share editing practices, have emerged as self-inclusion strategies to enable more women to enter, remain, and be recognized in this male-dominated editing environment. Smaller Wikipedia communities are also perceived as more inclusive environments. Lack of digital competences or difficulty using the platform do not appear to be aspects that negatively influence the participation of women in the editing process, though time spent on unpaid care work does seem to be a critical factor.

The objective of this work is to compare the performances of two electroencephalogram based indices for detecting loss of consciousness and loss of response to nociceptive stimulation. Specifically, their behaviour after drug induction and during recovery of consciousness was pointed out. Data was recorded from 140 patients scheduled for general anaesthesia with a combination of propofol and remifentanil. The qCON 2000 monitor (Quantium Medical, Barcelona, Spain) was used to calculate the qCON and qNOX. Loss of response to verbal command and loss of eye-lash reflex were assessed during the transition from awake to anesthetized, defining the state of loss of consciousness. Movement as a response to laryngeal mask (LMA) insertion was interpreted as the response to the nociceptive stimuli. The patients were classified as movers or non-movers. The values of qCON and qNOX were statistically compared. Their fall times and rise times defined at the start and at the end of the surgery were calculated and compared. The results showed that the qCON was able to predict loss of consciousness such as loss of verbal command and eyelash reflex better than qNOX, while the qNOX has a better predictive value for response to noxious stimulation such as LMA insertion. From the analysis of the fall and rise times, it was found that the qNOX fall time (median: 217 s) was significantly longer ( p value <0.05) than the qCON fall time (median: 150 s). At the end of the surgery, the qNOX started to increase in median at 45 s before the first annotation related to response to stimuli or recovery of consciousness, while the qCON at 88 s after the first annotation related to response to stimuli or recovery of consciousness ( p value <0.05). The indices qCON and qNOX showed different performances in the detection of loss of consciousness and loss of response to stimuli during induction and recovery of consciousness. Furthermore, the qCON showed faster decrease during induction. This behaviour is associated with the hypothesis that the loss of response to stimuli (analgesic effect) might be reached after the loss of consciousness (hypnotic effect). On the contrary, the qNOX showed a faster increase at the end of the surgery, associated with the hypothesis that a higher probability of response to stimuli might be reached before the recovery of consciousness.
