Published: November 2022

High rates of psychological distress including anxiety and depression are common in the doctoral community and the learning environment has a role to play. With the coronavirus disease (Covid-19) pandemic taking a toll on mental health it is necessary to explore the risk and protective factors for this population. Using data from the Covid-19: Global Study of Social Trust and Mental Health, the present study examined the relationship between Covid-19-related stressful educational experiences and doctoral students’ mental health problems. Moreover, it assessed the role of attentional ability and coping skills in promoting good mental health. One hundred and fifty-five doctoral students completed an online survey where micro-, meso- and macro-level educational stressors were measured. The Patient Health Questionnaire and the Generalized Anxiety Disorder Questionnaire were used to measure depression and anxiety symptoms, respectively. We also measured coping skills using a 13-item scale and attentional ability using a questionnaire. The results of multiple linear regression analyses showed that specific stressful educational experiences were unrelated but cumulative stressful educational experiences were related to increased depression symptoms (but not anxiety symptoms) in fully adjusted models. Additionally, higher coping skills and attentional ability were related to fewer depression and anxiety symptoms. Finally, no associations between demographics and other covariates and mental health problems were found. The experience of multiple educational stressful events in their learning environment due to Covid-19 is a key risk factor for increased mental illness in the doctoral community. This could be explained by the uncertainty that the Covid-19 pandemic has caused to the students.

Published: November 2022

Instilling a collaborative approach can widen participation to a range of stakeholders, enabling the diffusion of sustainability and increasing local capacity to meet decarbonisation targets to mitigate against climate change. Dingle Peninsula 2030 has emerged as an international case study of a collaborative regional sustainability project, whereby a wide range of initiatives, beyond the initial remit of the project, have emerged in the area. This holistic scale of action is required for effective climate action. Using the Sustainable Development Goals (SDGs) as a framing, the interrelated nature of climate action has been shown through this study. In setting out to undergo energy projects a wide range of new initiatives emerged as community members became engaged in the process. Initiatives have emerged related to energy, transport, agriculture, education, tourism and employment, in what we have coined the ‘diffusion of sustainability’.
Evaluación del desempeño docente en tiempos de pandemia: La opinión del estudiantado de tres universidades públicas Mexicanas

Published: November 2022

El estudio tiene como objetivo analizar la opinión del estudiantado de tres universidades públicas mexicanas acerca del desempeño de sus docentes en el marco de la modalidad virtual obligatoria por la pandemia COVID-19. Desde la declaración de la situación pandémica mundial, todos los niveles educativos trabajaron con modalidades a distancia de manera urgente, improvisada y, en muchos casos, no planificada. Este estudio considera dimensiones asociadas a la planificación de la enseñanza, metodologías y dinámicas de trabajo, estrategias de enseñanza y aprendizaje, junto con evaluación del aprendizaje durante el período 2020-2. Los resultados muestran que la mayoría de los docentes continuaron trabajando bajo dinámicas sincrónicas de clases, de lo cual se infiere una poca preparación y conocimiento en la elaboración de diseños instruccionales para la educación a distancia, perpetuando modelos educativos tradicionales, centrados principalmente en la transmisión de contenidos. Se destaca que la mayoría de los estudiantes opinó positivamente acerca de las modalidades de trabajo privilegiadas por sus docentes. Respecto a la evaluación del aprendizaje, se observó una opinión positiva del estudiantado: se sienten a gusto con dichas estrategias, consideran que se promueve y mejora su propio aprendizaje, aseverando que sus docentes recrean situaciones reales y auténticas para evaluar los contenidos.
Exploring state department of education grading guidance during COVID-19: A model for future emergency remote learning
Authors: Townsley Matt , Kunnath Joshua
Published: November 2022

Due to the COVID-19 pandemic, many United States brick-and-mortar schools in Spring 2020 rapidly transitioned to emergency remote learning. School leaders grappled with how grades ought to fit within the many unknowns of K-12 remote education. In some cases, schools modified their grading scales to give students greater flexibility to pass courses, and in other situations, schools offered incomplete grades in lieu of failures. During this time, state departments of education (DOEs) provided a variety of guidance documents to their school districts. The purpose of this study was to explore the components of state DOE grading guidance during the Spring 2020 school shutdown, along with the patterns of guidance across states. The researchers applied a grounded theory approach to systematically explore the equivalent of 1,444 pages of documents from 48 state DOE guidelines. The document analysis resulted in three primary categories that influenced state DOE grading guidance: guiding principles, student advancement, and determining grades. The researchers conclude by presenting and discussing a three-category model for emergency remote learning grading guidelines for K-12 schools. In the event of another pandemic temporarily affecting the delivery of education to students, policymakers may use this model as a starting point for future recommendations.

Developing an annotation protocol for evaluative stance and metaphor in discourse: theoretical and methodological considerations
Authors: Hidalgo-Downing Laura , Pérez-Sobrino Paula
Published: November 2022

The process of identification and annotation of evaluation has received a lot of attention in recent years. However, given the complexity of the topic, the discussion of some of the central issues is still ongoing. The present article contributes to this debate by presenting an annotation scheme that is designed for the identification and annotation of evaluative stance in a corpus of four English genres, namely, newspaper discourse, political discourse, newspaper scientific popularization and fora. A 4,862-word corpus was sampled from a larger 400,000-word corpus compiled within the research project STANCEDISC on the study of stance in discourse varieties. The scheme posits a series of ad hoc categories designed to optimise the transparency, reliability and replicability of the identification, annotation and analysis of evaluative stance. The categories are as follows: parts of speech (Noun Phrase, NP; Adjectival Phrase, AP; Adverbial Phrase, ADVP; Verbal Phrase, VP), function (classifying, predicational and attitude), metaphoricity (metaphoric and non-metaphoric), and value (positive and negative). The aim of this paper is to explain the scheme together with the theoretical justification of the categories and the methodological procedure adopted, and to illustrate the implementation of the scheme by discussing examples taken from different genres.
Founding Myth, Institutional Adaptation, and Regime Resilience in China
Authors: Huang Qingming
Published: November 2022

To explain the factors behind the regime resilience in China, this article focuses on the foundational and institutional resources that the Chinese Communist Party (CCP) accumulated in the earlier stages of regime development and their lasting influence on regime trajectory. At the stage of regime foundation, the CCP successfully constructed the founding myth of the party-state as the foundational resource to legitimize its rule. At the later stage of regime adaptation, institutional adaptation during the process of achieving modernization allowed the CCP to accumulate substantial institutional resources to further buttress the regime. While negotiating the space between state and society, the CCP regime demonstrated high capacity in granting more autonomy to market actors to accelerate growth while increasing the embeddedness of economic strata in the system through informal and formal institutional arrangements. When confronted with a serious crisis, the CCP was able to draw strength from the foundational and institutional resources to survive. This article argues that the CCP’s efforts in accumulating strength at the early stages of regime development continue to exert strong influence on China’s regime trajectory at later stages.

Published: November 2022

Located in the Southern Mata region of the state of Pernambuco, the Jaboatão River Hydrographic Basin (JRB) has an area of 442 km². Part of the group of small coastal rivers (GL2), the JRB drains the municipalities of Recife, Jaboatão dos Guararapes, Moreno, São Lourenço da Mata, Cabo de Santo Agostinho, and Vitória de Santo Antão. In addition to contributing to the public supply of the Metropolitan Region of Recife, the JRB receives domestic, industrial and agro-industrial effluents along its route. The JRB runs through densely occupied municipalities with irregular land use and deficiencies in infrastructure, reflecting social, economic and environmental problems. The objective of this study is to make a diagnosis of the socio-environmental indicators in the JRB and correlate them with the main waterborne diseases related to the lack of basic sanitation. The study involved a literature review and a survey of secondary data. Regarding the water quality of the JRB, it was found to vary between Polluted and Very Polluted during the monitored period. With regard to environmental impacts, deforestation, waste dumping and irregular occupation of riverbanks were observed, causing problems for the fauna, flora and the population. In relation to the basic sanitation indicator in the municipality of Jaboatão dos Guararapes, among the obstacles raised was the fact that the municipality does not have a Municipal Policy on Basic Sanitation and the Jaboatão dos Guararapes Municipal Administration does not have a Municipal Basic Sanitation Plan; There is a scarcity of systematized information that supports the process of measuring environmental health; between urban and rural areas there are disparities in access to sanitation services, requiring the adoption of public policies to expand sanitation services in order to assist these populations and thus promote the universalization of sanitation access. The deficiency in basic sanitation in the municipality of Jaboatão dos Guararapes hinders local sustainable development, causing social, economic and environmental impacts. Regarding the number of hospital admissions caused by diseases related to inadequate environmental sanitation (DRIES) in the municipalities that are part of the JRB, Recife stood out with 13,191 hospitalizations in the study period, and in 2010 had the highest number of hospitalizations (2,204). With regard to the number of deaths caused by DRIES, Recife also stood out with 4,208 deaths during the study period.
The Uses of Social Media in Journalism Practices: The Reversed-Agenda Setting on Television News Production
Authors: Humeira Bintan , Ramadhan Andika
Published: November 2022

This article aims to examine the use of social media by television journalists in Indonesia (Kompas TV) in the broadcast production process and the implications for changing the influence of the media on the public agenda. This research uses an agenda-setting perspective in the internet era and an in-depth interview method with senior journalists and broadcast producers. The results show that using social by journalists includes pre-production to post-production activities. From the type of information source, journalists often use four social media accounts: social media accounts belonging to influencers, community leaders (politicians, observers, or academics), institutions, and communities. This study also shows that conversations on social media are a means for the press to find issues of public concern and ultimately affect news content. Furthermore, this study supports the concept of a reversed-agenda setting in that the media is no longer dominant in determining the public agenda. On the other hand, the public has the power to decide on their agenda, not depending on the media. Public opinion often influences media coverage. Moreover, the logic of the digital space that emphasizes user engagement as a measure of popularity makes taking sides with the public important to increase digital traffic and has the potential to provide economic benefits. In addition, this research also finds that journalists often access social media accounts belonging to mainstream media as a source of information rather than visiting news sites owned by the media. It shows that social media allows for a more significant intermedia agenda-setting effect.
Coronary Stent Placement in an Interarterial Anomalous Right Coronary Artery: An Alternative Approach in a Multimorbid High-risk Surgical Patient
Authors: Simon Erik J , Rodriguez Ziccardi Mary , Sanghvi Saagar , Ardati Amer K
Published: November 2022

Anomalous aortic origin of a coronary artery is a rare congenital anomaly and potential aetiology for sudden cardiac death. However, the mere presence of this anomaly does not portend clinical significance, and there are many factors that contribute to limiting coronary blood flow in these patients. The standard of care for symptomatic individuals is surgical management with coronary unroofing although not all cases are amenable to surgery. We report the case of an anomalous right coronary artery with interarterial course managed by percutaneous coronary intervention due to surgical contraindication secondary to comorbidities. The proposed mechanism of action culminating in aborted sudden cardiac death is unique and involves aggravated pulmonary hypertension in an individual with severe comorbid pulmonary disease.
The effects of time duration and bilingualism/trilingualism on second-language production
Authors: Hsu Hsiu-ling
Published: November 2022

This investigation explored the effects of time duration and bilingualism/trilingualism on speakers' language production. A word-naming task was conducted under three conditions—700 ms, 1,000 ms, and unlimited time. The results showed that the participants incurred fewer errors and successfully corrected errors at 1,000 ms and unlimited time; the bilingual/trilingual advantage was identified in error self-repairs at 1,000 ms; and trilinguals were more strategic in correcting errors than monolinguals and bilinguals. This suggests that unlimited time did not ensure higher accuracy in lexical production and efficient error correction, and that 1,000 ms was the optimal timeframe for processing single monosyllabic Chinese characters.

Ecolinguistics and ecosophy
Authors: Ruijie Zhang , Wei He
Published: November 2022

This article presents a philosophical framework for studies of ecolinguistics, combining the Eastern wisdom of ecological harmony and the Western human geographical concept of sense of place. To establish the basic criteria for ecolinguistic analysis, the article traces the three most influential Chinese schools of philosophy and extracts three of their shared disciplines: benevolence, frugality and intimacy with nature. To reveal the dynamic relationship between human beings and the places where they reside, the article revisits the concept of sense of place and extends it to cover an ecological dimension of people and place. Connecting ecological ethics derived from classical Chinese philosophy with systemic human-place dynamics, this proposed framework provides an ideological basis for ecolinguistic research, especially for discourse analysis. Following this ecosophy, the involved human beings and other elements of places included in a discourse can be revealed through the system of sense of place; and the ecological implications of linguistic features can be evaluated according to the three major principles. To complete the analysis, positive and negative orientations will be distinguished as well as a middle ground of ambivalent orientation. To conclude, this article aims to provide a well-grounded ideological reference for the deconstruction and subsequent assessment of linguistic resources, and thereby to establish a crucial strand of ecolinguistic scholarship.
Genre, Ideology and Intertextuality
Authors: Martin James
Published: November 2022

This paper considers the relationship among three hierarchies in systemic functional linguistics, realisation, instantiation and individuation, focussing on how these can be used to interpret genre, intertextuality and ideology. The discussion considers four related war stories, especially with respect to appraisal analysis, and argues that a complementarity of hierarchies is needed to interpret their variously interested readings.

Published: November 2022

RESUMO A utilização de fibras celulósicas em matrizes cimentícias pode apresentar um efeito inibitório causando incompatibilidade química e inviabilizando o processo de produção de materiais de construção civil reforçados com fibras de celulose. Já as microceluloses geralmente aceleram a produção de gel de hidrato de silicato de cálcio (CSH) acelerando o grau de hidratação do cimento. Assim, o presente trabalho tem por objetivo o entendimento das interações combinadas entre microcelulose cristalina e fibra de celulose (MCC e FC) no processo de hidratação das pastas cimentícias. Os resultados obtidos no ensaio de inibição das pastas apontaram uma boa compatibilidade das fibras celulósicas e do sistema FC/MCC com as pastas cimentícias. Já para pastas cimentícias com substituição de cinza volante, o sistema FC/0,6%MCC apresentou moderada inibição apresentando diferença estatística significativa em relação aos demais tratamentos. Através do ensaio de difração de raios—X foi possível concluir que tanto as fibras celulósicas quanto o sistema FC/MCC não influenciaram na mineralogia dos compósitos, onde os padrões de difração mostraram os produtos de hidratação típicos dos aglomerantes minerais. Na análise de DRX foi possível identificar a redução dos picos de magnitude da Portlandita, com a incorporação de celulose MCC nas pastas cimentícias, o que indica menor disponibilidade de produtos C-S-H, podendo correlacionar com o retardo na hidratação das pastas cimentícias contendo celuloses FC/MCC.

Authors: Muniz Bruna Ariella Aguiar , Dantas Ana Lúcia Mota , Santana Mauricéa Maria de
Published: November 2022

Resumo Diante da magnitude do fenômeno da violência infantojuvenil no Brasil, que representa mais de um terço dos casos notificados por esse agravo no país, o objetivo deste estudo foi analisar a percepção dos profissionais de saúde acerca da identificação e da notificação compulsória dos casos de violência infantojuvenil na Atenção Primária à Saúde. Trata-se de um estudo exploratório, de abordagem qualitativa, realizado com 14 profissionais de duas unidades de Saúde da Família do Recife, Pernambuco, em 2021. Os dados foram coletados em entrevistas guiadas por um roteiro semiestruturado e analisados por meio da análise de Bardin. Os resultados apontam que os profissionais reconhecem a sua responsabilidade ética no processo de notificação de violência infantojuvenil, principalmente pelo contexto familiar e territorial no qual estão inseridos. Entretanto, ainda há muitos desafios que interferem na implicação prática da notificação na Atenção Primária, como o medo da violência e de represálias no território e a falta de capacitação. Investir em estratégias de estímulo à notificação, de modo a garantir respaldo técnico-científico, é imprescindível para a consolidação da prática.
EXPERIMENTAL STUDY OF THE RHEONOMIC PROPERTIES OF BREAKER RUBBER AND RUBBER-CORD COMPOSITE UNDER QUASI-STATIC LOADING
Authors: Sheshenin S. V. , Du Yikun , Chistyakov P. V. , Artamonova Nina B. , Klement'ev P. D.
Published: November 2022

Samples of filled breaker rubber and rubber-cord composite were tested for quasi-static cycling loadings with constant strain rates. The dependence of the rubber mix stress-strain diagram on the strain rate was revealed even for low strain rates. A difference was observed between stress-strain diagrams for the first loading and for subsequent ones. The second and subsequent diagrams are close to each other. This effect is referred to in the literature as the Mullins effect. Eight experiments were conducted with different loading programs to determine the manifestation of this effect for breaker rubber. The stress-strain curves depend differently on the strain rate for the first and subsequent loadings. The dependence on strain rate can be described as using the generalized Maxwell model for the first loading, but not for subsequent ones. Moreover, a similar study was done for a bi-ply rubber-cord sample with a 45° cord angle. The same conclusion regarding the Maxwell model applicability was also proven. Finally, numerical simulation of the bi-ply rubber-cord composite was carried out to determine the dimensions of the edge effect zones and, thereby, to estimate the allowable dimensions of the sample. Two types of boundary effects were revealed. Their dimensions were calculated for the 45° rubber-cord sample with various lengths. It was shown that short samples can also be used, if the longitudinal strain is properly recalculated.
EVAPORATION HEAT TRANSFER OF SINGLE HYDROUS ETHANOL DROPLET IMPACTING ON A HEATED WALL
Authors: Zheng Enhua , Wang Guanqing , Cui Yan , Wang Lu , Xu Jiangrong
Published: November 2022

The phenomenon of droplet impact on heated wall along with its evaporation is encountered in a variety of scenarios in industrial production. The present work aims to experimentally study the evaporation heat transfer of single hydrous ethanol droplet impact on a heated wall at saturation temperature under lower velocity. Its dynamic evolution after the impact, along with the stable adhesion morphology, was studied at different wall temperatures. The characteristics of its heat transfer and evaporation were analyzed by focusing on the effects of wall temperature, ethanol concentration, and adhesion morphology. The results show that the wall temperature has little effect on the spreading time, but significant on the spreading area and retraction. The "pining effect" of the hydrous ethanol weakens with the ethanol concentration, until it completely disappears. The film thickness along with its contact angle in adhesion evaporation shows a linear decrease accompanied by oscillations at the later stage. Evaporation heat transfer rate gradually increases with the wall temperature and ethanol concentration, and shows a multiple power function with them. The saturation temperature in evaporation gradually increases with the wall temperature, while the ethanol concentration has a minor effect. The average heat flux in evaporation can reach the magnitude of 10E5, and increases with the wall temperature and ethanol concentration.
Pupillary response to moving stimuli of different speeds
Authors: Wang Yuexin , Guo Yining , Wang Jiajia , Liu Ziyuan , Li Xuemin
Published: November 2022

Purpose: To investigate the pupillary response to moving stimuli of different speeds and the influence of different luminance environments.
Methods: Twenty-eight participants with normal or corrected-to-normal vision were included. The participants were required to track moving optotypes horizontally, and their pupils were videoed with an infrared camera. Stimuli of different speeds were presented in different luminance environments.
Results: Experiment 1 demonstrated that the motion stimuli induced pupil dilation in a speed-dependent pattern. The pupil dilation increased as the speed increased, and the pupil dilation gradually increased, then reached saturation. Experiment 2 showed that a stimulus targeting the rod- or cone-mediated pathway could induce pupil dilation in a similar speed-dependent pattern. The absolute but not relative pupil dilation in the cone paradigm was significantly larger than that in the rod paradigm. As the speed increased, the pupil dilation in the cone paradigm reached saturation at speed slower than the rod paradigm.
Conclusions: Motion stimuli induced pupil dilation in a speed-dependent pattern, and as the motion speed increased, the pupil dilation gradually increased and reached saturation. And the speed required to reach saturation in the cone paradigm was slower than in the rod paradigm.
Multimodality during fixation – Part II: Evidence for multimodality in spatial precision-related distributions and impact on precision estimates
Authors: Friedman Lee , Hanson Timothy , Komogortsev Oleg
Published: November 2022

This paper is a follow-on to our earlier paper (Friedman, Lohr, Hanson, & Komogortsev, 2021), which focused on the multimodality of angular offsets.  This paper applies the same analysis to the measurement of spatial precision.  Following the literature, we refer these measurements as estimates of device precision, but, in fact, subject characteristics clearly affect the measurements.  One typical measure of the spatial precision of an eye-tracking device is the standard deviation (SD) of the position signals (horizontal and vertical) during a fixation.  The SD is a highly interpretable measure of spread if the underlying error distribution is unimodal and normal. However, in the context of an underlying multimodal distribution, the SD is less interpretable. We will present evidence that the majority of such distributions are multimodal (68-70% strongly multimodal).  Only 21-23% of position distributions were unimodal. We present an alternative method for measuring precision that is appropriate for both unimodal and multimodal distributions.  This alternative method produces precision estimates that are substantially smaller than classic measures.  We present illustrations of both unimodality and multimodality with either drift or a microsaccade present during fixation.  At present, these observations apply only to the EyeLink 1000, and the subjects evaluated herein.

However, attempts to bring together research on expertise and eye tracking methodology provoke several challenges, because visual information processes should be studied in authentic and domain-specific environments. Among the barriers to designing appropriate research are the proper definition of levels of expertise, the tension between internal (experimental control) and external (authentic environments) validity, and the appropriate methodology to study eye movements in a three-dimensional environment. This exploratory study aims to address these challenges and to provide an adequate research setting by investigating visual expertise in sculpting. Eye movements and gaze patterns of 20 participants were investigated while looking at two sculptures in a museum. The participants were assigned to four different groups based on their level of expertise (laypersons, novices, semi-experts, experts). Using mobile eye tracking, the following parameters were measured: number of fixations, duration of fixation, dwell time in relevant areas, and revisits in relevant areas. Moreover, scan paths were analysed using the eyenalysis approach. Conclusions are drawn on both the nature of visual expertise in sculpting and the potential (and limitations) of empirical designs that aim to investigate expertise in authentic environments.

The assessment of visual field sensitivities in young children continues to be a challenge. Children often do not sit still, fail to fixate stimuli for longer durations, and have limited verbal capacity to report visibility. We investigated the use of a head-mounted VR display, gaze-contingent flicker pupil perimetry (gcFPP), and three fixation stimulus conditions to determine best practices for optimal fixation and pupil response quality. A total of twenty children (3-11y) passively fixated a dot, counted the repeated appearance of an animated character, and watched an animated movie in separate trials of 80s each. We presented large flickering patches at different eccentricities and angles in the periphery to evoke pupillary oscillations (20 locations, 4s per location). The results showed that gaze precision and accuracy did not differ significantly across the fixation conditions but pupil amplitudes were strongest for the dot and count task. We recommend the use of the fixation counting task for pupil perimetry because children enjoyed it the most and it achieved strongest pupil responses. The VR set-up appears to be an ideal apparatus for children to allow free range of movement, an engaging visual task, and reliable eye measurements.

Two eye-tracking experiments were used to investigate the mechanism of word satiation in Tibetan reading. The results revealed that, at a low repetition level, gaze duration and total fixation duration in the semantically unrelated condition were significantly longer than in the semantically related condition; at a medium repetition level, reaction time in the semantically related condition was significantly longer than in the semantically unrelated condition; at a high repetition level, the total fixation duration and reaction time in the semantically related condition were significantly longer than in the semantically unrelated condition. However, fixation duration and reaction time showed no significant difference between the similar and dissimilar orthography at any repetition level. These findings imply that there are semantic priming effects in Tibetan reading at a low repetition level, but semantic satiation effects at greater repetition levels, which occur in the late stage of lexical processing.

Este trabajo discute los resultados de la investigación experimental conducida para estudiar la inclusión de materiales reciclables como cascarilla de arroz, poliestireno expandido (icopor) y tereftalato de polietileno (PET( en la masilla para construcción liviana empleada para la fabricación de placas de Drywall como respuesta a la minimización del impacto ambiental y al aprovechamiento de las propiedades de los materiales desechados que son nuevamente introducidos en procesos productivos con el fin de obtener baja conductividad térmica, alta capacidad calorífica, alta capacidad de absorción sonora y cumplir con la normativa internacional para materiales de construcción; para ello se realizaron pruebas para medir cuatro propiedades como son el aislamiento térmico, capacidad calorífica y pruebas físico-mecánicas (resistencia a la flexión y resistencia a la tracción de clavo) por medio de probetas, teniendo en cuenta la normativa ASTM C 1396/C1396M-04 y ASTM C473-03, mientras que para la prueba de aislamiento acústico se utilizaron las normas ISO 16283-1 e ISO 717-1; los resultados obtenidos se procesaron aplicando un análisis estadístico multivariado empleando el software Statgraphics Centurion XVII que estableció los valores máximos y mínimos, la correlación de Pearson y ordinal de Spearman como método de análisis para el reporte del material más eficiente respecto a las cuatro propiedades medidas. La cascarilla de arroz, sustituyendo en un 60 % el peso del yeso en la masilla original, reportó los mejores resultados en cada una de las cuatro pruebas realizadas a lo largo de la investigación; de esta manera se confirma que es un material adecuado para la implementación en procesos de construcción liviana dado que demuestra que los materiales reciclables son eficientes y además poseen propiedades específicas como resistencia, liviandad y flexibilidad que le dan un valor agregado para ser utilizados nuevamente como reemplazo de materiales tradicionales.

Background

Regular follow-up visits and routine care is important for people with a mild bleeding disorder in terms of lowering their risk of complications from untreated bleeds and helping them maintain a healthy lifestyle. However, follow-up visits among this population can sometimes be missed for unclear reasons.

Aim

The present study aimed to question if lost-to-follow-up patients with a bleeding disorder experience unreported but important bleeding events that are not communicated to their haemophilia treatment centre (HTC) and if they could benefit from more frequent clinic visits.

Methods

A multicentre paper-based cross-sectional survey was sent to people diagnosed with an inherited blood disorder and lost to follow-up for two years or more. Those who met the eligibility criteria received the survey by mail and completed and returned it to their HTC between October 2015 and July 2016.

Results

Invitation packages were sent to 71 individuals; 14 questionnaires returned, with a survey response rate of 19.7%. Of the 14 returned surveys, only 11 participants were eligible who either responded completely or partially to the survey. Quality of life was reported as almost never or never a problem by all but one participant, who limited activities due to bleeding problems. Spontaneous nosebleeds were sometimes, often or always a problem for three participants; one female participant reported issues associated with heavy menstrual bleeding as often or almost always a problem.

Conclusion

We concluded that although the mean annual bleeding self-reported events were relatively low, they cannot be underestimated when keeping in mind the limitations and challenges of accessing data among this population. Our study highlighted the importance of educating this group of patients on their bleeding disorder and engaging them in their own care and health status, which may result in improving their health-related quality of life and overall health outcomes.
Personalising haemophilia management with shared decision making

The current standard of care for treating people with haemophilia (PWH) in the developed world is prophylaxis with regular infusions of clotting factor concentrates. Gene therapy is being investigated as a new treatment paradigm for haemophilia and if approved would potentially eliminate the need for chronic, burdensome infusions. In recent years, shared decision making (SDM) has become increasingly common in patient care settings. SDM is a stepwise process that relies on reciprocal information sharing between the practitioner and patient, resulting in health care decisions stemming from the informed preferences of both parties. SDM represents a departure from the traditional, paternalistic clinical model where the practitioner drives the treatment decision and the patient passively defers to this decision. As the potential introduction of gene therapy in haemophilia may transform the current standard of care, and impact disease management and goals in unique ways, both practitioners and PWH may find their knowledge tested when considering the appropriate use of a novel technology. Therefore, it is incumbent upon haemophilia practitioners to foster an open, trusting, and supportive relationship with their patients, while PWH and their caregivers must be knowledgeable and feel empowered to participate in the decision making process to achieve truly shared treatment decisions.
