UMA IGREJA SINODAL E MINISTERIAL: NOVOS IMPULSOS PARA A AMAZÔNIA E O MUNDO
Authors: Martins Filho José Reinaldo Felipe
Published: December 2020

O presente artigo constitui-se como uma tentativa de ler o percurso sinodal desenvolvido pela Igreja na Amazônia, desde a apresentação das primeiras contribuições, passando pela realização do Sínodo em Roma, até a publicação da Exortação Pós-Sinodal Querida Amazônia, pelo Papa Francisco. Para isso, particulariza a discussão ao redor da questão da sinodalidade e da ministerialidade, ambas implicadas na formulação de uma nova Teologia. Como principal contribuição, pretende-se ler o Sínodo da Amazônia para além dos clichês geralmente utilizados pelas mídias de comunicação, enfatizando-o como ponto de partida para a Igreja na Amazônia e no mundo.
HOSPITALIDADE E RELIGIÃO NÓMADA: IDENTIDADE PARA ALÉM DA VIOLÊNCIA
Authors: Duque Joao Manuel
Published: December 2020

Partindo de uma noção fechada de identidade, seja pela sua redução territorial seja pela sua redução cultural ou mesmo individual, que poderia encontrar apoio numa concepção de religião como posse exclusiva da referência a um único Deus verdadeiro ou como processo sacrificial, chegar-se-á a uma relação inevitável entre religião e violência. Propõe-se aqui um outro princípio, inspirado em Paul Ricoeur, Jacques Derrida, Jan Patocka e Emmanuel Levinas, que explora a dimensão excessiva e gratuita do religioso, interpretado como responsabilidade e com aplicação concreta no dinamismo da hospitalidade incondicional. Isso origina identidades religiosas nómadas, as quais estariam, em princípio, imunes à possibilidade de violência, a não ser que se trate de uma “violência” contra a violência, por exigência identitária.
A NOVA METAFÍSICA E A COMPREENSÃO DA RELIGIÃO
Authors: Oliveira Manfredo Araújo de
Published: December 2020

Depois das diferentes teorias da secularização e da extraordinária “irrupção dos deuses” no nosso século, a religião se tornou objeto fundamental de investigação de inúmeras ciências e de inúmeras propostas filosóficas. Como compreende a filosofia o fenômeno religioso? O que especifica sua consideração da religião? A filosofia estrutural sistemática de L.B. Puntel a considera a partir de dois níveis que ele denomina enfoques. O enfoque 1 considera o fenômeno religioso a partir do espírito humano enquanto intencionalmente coextensivo com o Ser em seu todo. O ser humano tende a entender em sua vida concreta a posição que ele ocupa no universo e articular uma forma correspondente à sua vida através da referência explícita a esse espaço abrangente entendendo-o como uma inteligência suprema derradeira e vontade suprema derradeira. O enfoque 2 procura esclarecer a partir de si mesma a dimensão última ou suprema antes mencionada como o ponto de referência fundamental e absolutamente central da religião.

Published: December 2020

Objective: Despite increasing interest in understanding factors influencing awareness, knowledge, and acceptability of the human papilloma virus (HPV) vaccine among Latino parents to date, limited information is available specific to Latino fathers living in the United States. Methods: This descriptive qualitative study explored Latino fathers’ awareness, knowledge, and acceptability of the HPV vaccine for their adolescent children. Data were collected through individual, semi-structured interviews and analyzed using a hybrid method of thematic analysis that incorporated deductive and inductive approaches. Results: Nineteen, majority foreign-born Latino fathers (63.2%; n = 12) fathers of male and female adolescents participated in the study. Four main themes and two subthemes emerged from the analyses. Results found fathers’ low awareness and knowledge of HPV and the HPV vaccine. Results also identified fathers’ positive attitude toward vaccines in general. Moreover, results revealed fathers’ trust in healthcare providers. This trust translated into an increased willingness to vaccinate their children against HPV if recommended by their child’s primary healthcare provider. Conclusion: Findings indicate the need for increased efforts to raise awareness and knowledge among Latino fathers of HPV and the HPV vaccine. In addition, findings underscore the critical role of healthcare providers’ recommendation of the HPV vaccine. Given the limited research focused on Latino fathers, this study’s findings are valuable in building a knowledge foundation needed for developing future studies and interventions to promote the HPV vaccine by targeting Latino fathers living in the United States. Future research should quantify Latino fathers' awareness, knowledge, and acceptability of the HPV vaccine for their children, and preferences for educational interventions to promote HPV vaccination.

Published: December 2020

The e-commerce platform in the digital economy era has evolved into a data platform ecosystem built around data resources and data mining technology systems. The most typical applications of big data are also concentrated in the field of e-commerce. E-commerce companies should first grasp the interactive relationship among the three major factors of data, technology and innovation, e-commerce platform operation is a multidisciplinary research field. It is not easy for researchers to obtain a panoramic view of the knowledge structure in this field. Knowledge graph is a kind of graph that shows the development process and structure relationship of knowledge with the field of knowledge as the object. It is not only a visual knowledge mapping, but also a serialized knowledge pedigree, which provides researchers with a quantitative research method for the development trend of statistics and academic status. The purpose of this research is to help researchers understand the key knowledge, evolutionary trends and research frontiers of current research. This study uses Citespace bibliometric analysis to analyze the data of the Science Net database and finds that: 1) The development of the research field has gone through three stages, and some representative key scholars and key documents have been recognized; 2) the common knowledge mapping of literature The co-occurrence of citations and keywords shows research hotspots; 3) The results of burst detection and central node analysis reveal research frontiers and development trends. Today, the visualization of big data brings different challenges. The abstraction between the world and today's data visualization occurs when the data is captured. Every user sees his own visualization data generated by standardized calculations. At the same time, there are still many controversies in the theoretical model, structure and structural dimensions. This is the direction that future researchers need to further study.
LiDAR Observations of Multi-modal Swash Probability Distributions on a Dissipative Beach
Authors: Eadi Stringari Caio , E. Power Hannah
Published: December 2020

Understanding swash zone dynamics is of crucial importance for coastal management as the swash motion, consisting of the uprush of the wave on the beach face and the subsequent downrush, is responsible for driving changes the beach morphology trough sediment exchanges between the sub-aerial and sub-aqueous beach. Improved understanding of the probabilistic characteristics of these motions has the potential to allow coastal engineers to develop improved sediment transport models which, in turn, can be further developed into coastal management tools. In this paper, novel descriptors of swash motions are obtained by combining field data and statistical modelling. Our results indicate that the probability distribution function (PDF) of shoreline height (p(ζ)) and trough-to-peak swash heights (p(ρ)) measured at a high energy, sandy beach were both inherently multimodal. Based on the observed multimodality of these PDFs, Gaussian Mixtures are shown to be the best method to statistically model them. Further, our results show that both offshore and surf zone dynamics are responsible for driving swash zone dynamics, which indicates unsaturated swash. The novel methods and results developed in this paper, both data collection and analysis, could aid coastal managers to develop improved swash zone models in the future.

Published: December 2020

Dredged materials provide a number of beneficial use opportunities, including beach nourishment, habitat creation and restoration, and other activities. In situ sediment color is important for determining aesthetic and habitat suitability, for beach nourishment, and for other projects. However, dredged materials must meet locally established color compatibility requirements (for example, material cannot be too dark). Often, potential sediment sources are close to meeting specified color thresholds, and previous observations suggest that sediments lighten over time. In response to these observations, this study quantified sediment color change potential in a dredged m aterial management context. Results indicate that dredged material sediment color responded to changes in secondary color components, sediment mixing, and photolytic bleaching improving the sediment color for beneficial use application. Findings allowed for development of a conceptual color change capacity framework and supported development of tools for resource managers to incorporate color change dynamic into planning and operations activities.The following report provides a framework for determining the color change capacity of dredged materials using (1) a comprehensive laboratory approach and (2) a semiquantitative index based on source material and placement location conditions. These tools allow practitioners to incorporate dredged-material color change into resource management decisions, thus increasing beneficial use opportunities.

Published: December 2020

Objective: Uterine after-pains are among the most prevalent complaints after natural vaginal delivery. Non-pharmacological treatment modalities to relieve after-pains are an important care priority. This study aimed to investigate the effect of foot reflexology in the fourth stage of labor on after-pains in multiparous women.Methods: This single-blind randomized clinical trial recruited 80 eligible pregnant women presenting to Allameh Bohlool Hospital in Gonabad and 17-Shahrivar Hospital in Mashhad in 2019. In the first and second hours postpartum, the reflexology group received 10 minutes of general massage and specific reflexology massage on each foot in uterine, pituitary, and solar plexus points. The control group received 10 minutes of general massage, and then rotational massage on a neutral point on the lateral side of the heel. The pain was measured every hour up to 4 hours postpartum using a visual analog scale. The collected data were analyzed in SPSS-16 software at a significance level of P<0.05.Results: The median of after-pain score in the first hour postpartum was not statistically significantly different between the two groups (P=0.05), but it was lower in the reflexology group at the second (P=0.04), third (P<0.001), and fourth hours postpartum (P<0.001). The mean total after-pain score of the four hours postpartum was significantly lower in the reflexology group (P<0.001).Conclusions: The results revealed that foot reflexology in the fourth stage of labor has positive effects on the relief of uterine after-pain. It is therefore recommended that reflexology be used to reduce postpartum uterine after-pain.

Published: December 2020

Delirium is one of the most common postoperative complications in surgical procedures. Postoperative delirium (POD) may affect normal recovery and outcomes after surgery. Degenerative Cervical myelopathy (DCM), a disease that progresses with age, usually associated with neurological symptoms. This study is designed to analyze the incidence and risk factors that cause post-operative delirium in DCM. The incidence and risk factors of delirium were analyzed in 148 patients aged 60 years or older who underwent surgery for DCM. Among the 148 patients who underwent surgery, 78 received laminoplasty, of whom 19 patients (24%) experienced delirium; the other 70 patients underwent ACDF, of whom five patients (7.1%) experienced delirium. The occurrence of POD in the laminoplasty group was 4.18 times higher than that in the ACDF group. Age, and sodium level were found to be significant risk factors for all 148 patients in a multivariate analysis. In the laminoplasty group, age, and high potassium level were meaningful risk factors in multiple regression analysis. Risk factors that affect the POD were not analyzed in ACDF due to the low n(=5). This study shows that the incidence and risk factors for POD can vary depending on the surgical method employed in patients with DCM.
Oil Palm Cultivation Critically Affects Sociality in an Endangered Malaysian Primate
Authors: Holzner Anna , Balasubramaniam Krishna , Ruppert Nadine , Widdig Anja
Published: December 2020

Human-induced habitat alterations globally threaten animal populations, often evoking complex behavioural responses in wildlife. This may be particularly dramatic when negatively affecting social behaviour, which fundamentally determines individual fitness and offspring survival in group-living animals. Here, we provide first evidence for critical behavioural modifications in sociality of Southern pig-tailed macaques visiting Malaysian oil palm plantations in search of food. Specifically, we found significant reductions of positive social interactions, an increase of aggression and shifts in the macaques' social network structure, with the central positions of high-ranking adult females and immatures being passed to low-ranking individuals, likely resulting from socio-ecological risks posed by plantations. Deviations from natural behaviour also affected the smallest but crucial social units within groups, mother-infant pairs, with increased maternal protectiveness at plantations. We suggest that although primates can persist in human-altered habitats, their ability to adapt comes with a trade-off for their natural sociality, potentially hampering infant development and individual survival. Studies like ours remain critical for understanding species’ adaptability to anthropogenic landscapes, which may ultimately contribute to facilitating their coexistence with humans and preserving biodiversity.

Published: December 2020

Glycated hemoglobin and blood oxygenation are the two most important factors for monitoring a patient’s oxygen levels in the blood and the amount of average blood glucose levels. Digital Volume Pulse acquisition is a convenient method, even for a person with no previous training or experience, can be utilized to estimate the two abovementioned physiological parameters. The physiological basis assumptions are utilized to develop two-finger models for estimating the percent glycated hemoglobin and blood oxygenation levels. The first model consists of a blood vessel only hypothesis, while the second model is based on a whole-finger model system. We validated our two gray-box systems on diabetic and non-diabetic patients and obtained the mean absolute errors for the percent glycated hemoglobin (%HbA1c) and percent oxygen saturation (%SpO2) of 0.375 and 1.676, respectively, for the blood vessel model and 0.271 and 1.395, respectively, for the whole-finger model. The precision analysis indicated that these models resulted in 2.08% and 1.74% mean %CV for %HbA1c and 0.54% and 0.49% mean %CV for %SpO2 in the respective models. Herein, both models exhibit close performances to each other (HbA1c estimation Pearson R values are 0.92 and 0.96, respectively), even though the model assumptions greatly differed between them. Both of the models have a very high potential to be used in real-world scenarios. The whole-finger model performs better in terms of higher precision and accuracy compared to the blood vessel model.

Published: December 2020

Background: N6-methyladenosine (m6A) RNA modification play critical roles in multiple levels including the regulation of degradation, subcellular localization, splicing and local conformation changes of RNA transcripts. In this study, we aim to conduct comprehensive investigation on m6A RNA methylation regulators and m6A-related genes and their association with prognosis in early-stage Lung adenocarcinoma (LUAD). Methods: The relevant datasets which were used to analyze 21 m6A RNA methylation regulators and 887 m6A-related genes in m6Avar were downloaded from Gene Expression Omnibus database (GEO) and The Cancer Genome Atlas (TCGA) databases. Univariate cox regression analysis, random survival forest analysis, Kaplan-Meier anylysis, STRING and multivariate cox analysis were carried out, and a risk prognostic model based on five feature genes was constructed. Respectively, we treated GSE31210 (n=226) as training set, GSE50081 (n=128) and TCGA data (n=461) as test set. Results: By performing univariable cox regression and random survival forest algorithm in the training group, five prognosis-related genes including DENND1A, KBTBD6, KIF4A, BMPER, and YTHDC2 were screened out, which could divide LUAD patients into low-risk group and high-risk group (log rank p <0.001). The predictive efficacy of these genes was confirmed in the test group GSE50081 (log rank p <0.01) and TCGA datasets (log rank p <0.001). Cox analysis showed that this five-gene signature was an independent risk factor in LUAD. Further, genes in the signature were also external validated using online database. YTHDC2 played vital role of readers in m6A methylation. Conclusions: The findings of this study suggested that associated with m6A-related genes and m6A RNA methylation regulators, five-gene signature was reliable prognostic indicator for LUAD patients, indicating a clinical application prospect to serve as a potential therapeutic target.

Published: December 2020

Background: The aim of this study was to investigate the impact of the neutrophil-lymphocyte ratio (NLR) in sleeve gastrectomy (SG).Methods: 15 obese patients were enrolled in this study. They consisted of 5 males and 10 females: mean body weight (BW) 127.5kg; mean body mass index (BMI) 46.7kg/m2. 10 of these were diabetics who underwent a SG. The impact of the pre-operative NLR on the percentage of excess weight loss (%EWL) and remission of diabetes 1 year post-operative were examined.Results: The BMI, %EWL and %TWL at 1 year post-operative were 35.1 kg/m2, 46.3% and 26.2%, respectively. Improvements were also evident in the diabetes at 1 year post-operative: complete remission (CR) (No medication and hemoglobin A1c (HbA1c) HbA1c<6.0%) 40%, PR (HbA1c<6.5) 20%; and (decrease of anti diabetic drug and HbA1c<7.0%) 40%. Comparing pre-operative NLR in %EWL<50% and >50% in one (1) year post-operative, <50% was 2.64 and >50% was 2.03 (p<0.05). The NLR in CR and partial remission (PR) was significantly lower than that in improved (Improve) (2.22 vs 3.27, p<0.05).Conclusions: The pre-operative NLR may be a predictive marker of weight loss and improving diabetes after SG.
Adapting Lot Quality Assurance Sampling to accommodate imperfect tests: application to COVID-19 serosurveillance in Haiti
Authors: Fulcher Isabel , Clisbee Mary , Lambert Wesler , Leandre Fernet Renand , Hedt-Gauthier Bethany
Published: December 2020

Background: Lot Quality Assurance Sampling (LQAS), a tool used for monitoring health indicators in low resource settings resulting in “high” or “low” classifications, assumes that determination of the trait of interest is perfect. This is often not true for diagnostic tests, with imperfect sensitivity and specificity. Here, we develop Lot Quality Assurance Sampling for Imperfect Tests (LQAS-IMP) to address this issue and apply it to a COVID-19 serosurveillance study in Haiti.Results: As part of the standard LQAS procedure, the user specifies allowable classification errors for the system, which is defined by a sample size and decision rule. We show that when an imperfect diagnostic test is used, the classification errors are larger than specified. We derive a modified procedure, LQAS-IMP, that accounts for the sensitivity and specificity of a diagnostic test to yield correct classification errors. We apply our methods to create a sampling scheme at Zanmi Lasante health facilities in Haiti to assess the prior circulation of COVID-19 among healthcare workers (HCWs) using a limited number of antibody tests. Conclusions: The LQAS-IMP procedure accounts for imperfect sensitivity and specificity in system design; if the accuracy of a test is known, the use of LQAS-IMP extends LQAS to applications for indicators that are based on laboratory tests, such as COVID-19 antibodies.
Managing development plans in the Norwegian healthcare system
Authors: Vik Erlend , Hansson Lisa
Published: December 2020

Background: As part of a national plan to govern professional and organizational development in Norwegian specialist healthcare, the country’s hospital clinics are tasked with making development plans. Using the development plan as case, the paper analyses how managers navigate and legitimize the development plan process among central actors, and deals with the tension between governmental control and organizational autonomy in such strategy work.Method: This study applies a qualitative research design, triangulating different kinds of data. The study was performed in two steps: a) an analysis of various guidelines for development plans and how they are translated through the different levels of Norwegian specialist healthcare, and b) a single-case study of the process of developing a development plan at the clinical level. Findings: Findings shows that the development plan was shaped through a multilevel translation process consisting of different contending rationalities. At the clinical level, the management had difficulties legitimizing the process. Underlying tension between top-down and bottom-up steering challenged their involvement and made it difficult to manage the contingency of decisions.Conclusions: The findings are relevant to public sector managers working on strategy documents, as well as to policymakers identifying challenges that might hinder fulfillment of political intentions. This paper uses a case from Norway; however, the findings are of general interest. It contributes to the academic discussion on how to take account both the health authorities perspective and the organizational perspective in order to understand tensions between control and autonomy, applied to a functionally differentiated health care system.
Potential inpatient hospital care accessibility scores: association with healthcare utilization and non-hospital care service accessibility
Authors: GAO Fei , Jaffrelot Matthieu , Deguen Séverine
Published: December 2020

Background: Optimal healthcare access improves people's health status and decreases health inequalities. Many studies demonstrated spatial access importance in health outcomes. Recent studies assessed spatial healthcare access using the enhanced two-step floating catchment area (E2SFCA) method. The study aim was to build a hospital facility access indicator at a fine geographic scale and to assess the impact of spatial accessibility to inpatient hospital care and non-hospital care services on the length of hospital stay (LOS). Methods: This study focused on the ≥75-year-old population of the Nord administrative region of France. Hospital spatial accessibility was computed with the E2SFCA method, and then the LOS score was calculated from the French national hospital activity and patient discharge database. Linear regression models were used to analyze the relationship between LOS and spatial accessibility to inpatient hospital care and to three types of non-hospital care services (general practitioners, physiotherapists, and home-visiting nurses). Results: Overall, there were 19.0 beds in Medical, Surgical and Obstetrics (MCO) facilities and 5.58 beds in Postoperative and Rehabilitation Care facilities (SSR) per 10,000 inhabitants, but with important geographic variations. Accessibility to hospital services was higher for people in large urban areas, despite the dense population and the higher demand. In 2014, the mean LOS scores were 0.26 for MCO and 0.85 for SSR, with a non-homogeneous geographical repartition. The linear regression analysis revealed a strong negative and significant association between LOS and non-hospital care accessibility.Conclusions: This is the first study to measure spatial accessibility to inpatient hospital care in France using the E2SFCA method, and the first to investigate the relationship between healthcare utilization (LOS) and spatial accessibility to inpatient hospital care facilities and three types of non-hospital care services. Our findings should help to take decisions about deploying additional beds and to identify the best locations for non-hospital care services. Moreover, they should also help to improve access, and to ensure the best coordination and sustainability of inpatient and outpatient services, in order to better cover the population’s healthcare needs. Other international studies using multiple consensual indicators of healthcare outcomes and accessibility and sophisticated modeling methods should be developed.
Combining the Knowledge Appropriation Model and epistemic networks to understand co-creation and adoption of learning designs using log data
Authors: Rodríguez-Triana María Jesús , Prieto Luis P. , Ley Tobias , Gillet Denis , De Jong Ton
Published: December 2020

Social practices are well-known mediators in the adoption of educational innovations during professional learning, as postulated by the Knowledge Appropriation Model (KAM). However, understanding how teachers adopt new pedagogical approaches at scale is often difficult due to the lack of evidence available about their daily practices. In that sense, log data from online authoring and learning tools offer the possibility of better understanding the creation process of a learning design that reifies an educational innovation. 

This paper explores how statistical models and Epistemic Network Analysis (ENA) can help us understand large-scale patterns in the co-creation and adoption of educational innovations, using KAM as a theoretical framework to analyse log data. More concretely, this paper presents a case study on Go-Lab, an initiative to promote inquiry-based learning at school. Its authoring and learning tool -Graasp- gives us a unique opportunity to track, not only the (co)creation of learning designs, but also their potential implementation in the classroom. The case study uses the aforementioned methodological approach to analyse the role of large-scale support initiatives in the co-creation and adoption of learning designs.

Published: December 2020

In this work, we report a method to quantify methylparaben, ethylparaben, propylparaben and butylparaben in urban waters of São Carlos (São Paulo State, Brazil) by online solid phase extraction-liquid chromatography tandem mass spectrometry (SPE-LC-MS/MS) system. The method achieved ng L-1 limits with good accuracy and precision (internal standards for each paraben were used). The total run cycle time takes 9.5 min per sample including the extraction, cleanup and columns conditioning cycles, lower collection volumes of urban water and solvent usage. The SPE cartridge applied showed robustness allowing over 500 sample injections (800 μL each) with good chromatographic performance. This study findings included the detection of parabens in samples in São Carlos.
Designing of a high speed, compact and low power, balanced-input balanced-output preamplifier latch based comparator
Authors: Chen Ning , Zhang Man
Published: December 2020

Analog and digital converters (ADCs) are the most inevitable part of today’s high-speed human interacted devices. Continuous efforts are being made to improve their performance. Despite working for the improvement of whole ADC, efforts to improve sub-modules are also significant. Comparators are also a vital part of ADC. In this work, we have proposed a novel high-speed Balanced-Input Balanced-Output (BIBO) preamplifier latch based comparator design, to be used for the designing of an Asynchronous Successive Approximation Resister (SAR) ADC. In order to make comparison faster, we have employed Preamplifier-Latch based comparator. Transistor fingering is used to save area and makes large transistor easy to handle without changing their aspect ratio. We have implemented this latch using two back to back connected inverters. These inverters are farming a positive feedback arrangement that also prohibits the comparator from bursting into the oscillation. Latch circuit uses three non-overlapping phases namely phi1, phi2 and phi3 and dissipates less power when operated on a single 1V supply voltage. All these features collectively made this comparator expedient and obtained results confirm that it can be used effectively for the designing of SAR ADC.

Published: December 2020

BACKGROUND

Ecological momentary assessment (EMA) tools appear to be useful interventions for collecting real-time data on patients’ behavior and functioning. However, concerns have been voiced regarding the acceptability of EMA among patients with schizophrenia and the factors influencing EMA acceptability.

OBJECTIVE

The aim of this study was to investigate the acceptability of a passive smartphone-based EMA app, evidence-based behavior (eB2), among patients with schizophrenia spectrum disorders and the putative variables underlying their acceptance.

METHODS

The participants in this study were from an ongoing randomized controlled trial (RCT) of metacognitive training, consisting of outpatients with schizophrenia spectrum disorders (F20-29 of 10th revision of the International Statistical Classification of Diseases and Related Health Problems), aged 18-64 years, none of whom received any financial compensation. Those who consented to installation of the eB2 app (users) were compared with those who did not (nonusers) in sociodemographic, clinical, premorbid adjustment, neurocognitive, psychopathological, insight, and metacognitive variables. A multivariable binary logistic regression tested the influence of the above (independent) variables on “being user versus nonuser” (acceptability), which was the main outcome measure.

RESULTS

Out of the 77 RCT participants, 24 (31%) consented to installing eB2, which remained installed till the end of the study (median follow-up 14.50 weeks) in 14 participants (70%). Users were younger and had a higher education level, better premorbid adjustment, better executive function (according to the Trail Making Test), and higher cognitive insight levels (measured with the Beck Cognitive Insight Scale) than nonusers (univariate analyses) although only age (OR 0.93, 95% CI 0.86-0.99; P=.048) and early adolescence premorbid adjustment (OR 0.75, 95% CI 0.61-0.93; P=.01) survived the multivariable regression model, thus predicting eB2 acceptability.

CONCLUSIONS

Acceptability of a passive smartphone-based EMA app among participants with schizophrenia spectrum disorders in this RCT where no participant received financial compensation was, as expected, relatively low, and linked with being young and good premorbid adjustment. Further research should examine how to increase EMA acceptability in patients with schizophrenia spectrum disorders, in particular, older participants and those with poor premorbid adjustment.

Published: December 2020

BACKGROUND

International guidelines consistently endorse the promotion of self-management for people with low back pain (LBP); however, implementation of these guidelines remains a challenge. Digital health interventions, such as those that can be provided by smartphone apps, have been proposed as a promising mode of supporting self-management in people with chronic conditions, including LBP. However, the evidence base for digital health interventions to support self-management of LBP is weak, and detailed descriptions and documentation of the interventions are lacking. Structured intervention mapping (IM) constitutes a 6-step process that can be used to guide the development of complex interventions.

OBJECTIVE

The aim of this paper is to describe the IM process for designing and creating an app-based intervention designed to support self-management of nonspecific LBP to reduce pain-related disability.

METHODS

The first 5 steps of the IM process were systematically applied. The core processes included literature reviews, brainstorming and group discussions, and the inclusion of stakeholders and representatives from the target population. Over a period of >2 years, the intervention content and the technical features of delivery were created, tested, and revised through user tests, feasibility studies, and a pilot study.

RESULTS

A behavioral outcome was identified as a proxy for reaching the overall program goal, that is, increased use of evidence-based self-management strategies. Physical exercises, education, and physical activity were the main components of the self-management intervention and were designed and produced to be delivered via a smartphone app. All intervention content was theoretically underpinned by the behavior change theory and the normalization process theory.

CONCLUSIONS

We describe a detailed example of the application of the IM approach for the development of a theory-driven, complex, and digital intervention designed to support self-management of LBP. This description provides transparency in the developmental process of the intervention and can be a possible blueprint for designing and creating future digital health interventions for self-management.

Published: December 2020

BACKGROUND

The emergence of SARS-CoV-2 in late 2019 and its subsequent spread worldwide continues to be a global health crisis. Many governments consider contact tracing of citizens through apps installed on mobile phones as a key mechanism to contain the spread of SARS-CoV-2.

OBJECTIVE

In this study, we sought to explore the suitability of artificial intelligence (AI)–enabled social media analyses using Facebook and Twitter to understand public perceptions of COVID-19 contact tracing apps in the United Kingdom.

METHODS

We extracted and analyzed over 10,000 relevant social media posts across an 8-month period, from March 1 to October 31, 2020. We used an initial filter with COVID-19–related keywords, which were predefined as part of an open Twitter-based COVID-19 dataset. We then applied a second filter using contract tracing app–related keywords and a geographical filter. We developed and utilized a hybrid, rule-based ensemble model, combining state-of-the-art lexicon rule-based and deep learning–based approaches.

RESULTS

Overall, we observed 76% positive and 12% negative sentiments, with the majority of negative sentiments reported in the North of England. These sentiments varied over time, likely influenced by ongoing public debates around implementing app-based contact tracing by using a centralized model where data would be shared with the health service, compared with decentralized contact-tracing technology.

CONCLUSIONS

Variations in sentiments corroborate with ongoing debates surrounding the information governance of health-related information. AI-enabled social media analysis of public attitudes in health care can help facilitate the implementation of effective public health campaigns.

BACKGROUND

Two psychosocial constructs that have shown consistent associations with negative health outcomes are discrimination and perceived unfairness.

OBJECTIVE

The current analyses report the effects of discrimination and unfairness on medical, psychological, and behavioral outcomes from a recent cross-sectional survey conducted in a multiethnic sample of adults in Michigan.

METHODS

A cross-section survey was collected using multiple approaches: community settings, telephone-listed sample, and online panel. Unfairness was assessed with a single-item previously used in the Whitehall study, and everyday discrimination was assessed with the Williams 9-item scale. Outcomes included mental health symptoms, past-month cigarette use, past-month alcohol use, past-month marijuana use, lifetime pain medication use, and self-reported medical history.

RESULTS

A total of 2238 usable surveys were collected. In bivariate analyses, higher unfairness values were significantly associated with lower educational attainment, lower age, lower household income, and being unmarried. The highest unfairness values were observed for African American and multiracial respondents followed by Middle Eastern or North African participants. Unfairness was significantly related to worse mental health functioning, net adjustment for sociodemographic variables, and everyday discrimination. Unfairness was also related to self-reported history of depression and high blood pressure although, after including everyday discrimination in the model, only the association with depression remained significant. Unfairness was significantly related to 30-day marijuana use, 30-day cigarette use, and lifetime opiate use.

CONCLUSIONS

Our findings of a generally harmful effect of perceived unfairness on health are consistent with prior studies. Perceived unfairness may be one of the psychological pathways through which discrimination negatively impacts health. Future studies examining the relationships we observed using longitudinal data and including more objective measures of behavior and health status are needed to confirm and extend our findings.

KENDİNE YETME ERDEMİ OLARAK AYLAKLIK: KİNİKLER ÖRNEĞİ
Authors: ÖNAL Mehmet , ÇELEBİ Emin
Published: December 2020

Bu çalışmada öncelikle aylaklığın tanımına yönelik bazı değerlendirmeler yapılacak ve onun, asalaklık ve tembellik kavramları ile olan ilişkisi değerlendirilecektir. Böylece hem aylaklığın genel anlamı ve temel özellikleri ortaya çıkarılacak hem de onun dayanağı olan kendine yetme erdemi ana hatlarıyla araştırmaya konu edilecektir. Bu bağlamda kendine yetme erdemi, Sokrates öncesi doğa filozoflardan başlayarak başta Varoluşçular olmak üzere çağdaş filozoflara kadar gelen çizgide temel işlevi açısından ele alınacak, ancak ağırlıklı olarak Kinikler üzerinden örneklendirilecektir. Özellikle özgürlük ile kendine yetme erdemi ilişkisi bireysellik zemini üzerinden tartışılacaktır. Bu bağlamda Egzistansiyalist felsefede kendine yetme, benliğin inşasını mümkün kılan ve varoluşsal özü yaratan bir yaşama tercihi ve özgürlük anlayışı olarak ayrıca ele alınacaktır. Kısacası makalenin temel tezi, aylaklığın kavram olarak yanlış anlaşıldığı, felsefe ve sosyal hayata yaptığı katkıların göz ardı edildiği yönündedir. Böylece, makalede aylaklığın sadece tembellik olarak anlaşılan negatif anlamdan kurtulması ve kendine yetme, özgür ve bağımsız yaşama tarzı olarak sanat, felsefe ve pratik hayata yansımaları özellikle kendine yetme erdemi üzerinden temellendirilmiş olacaktır.
“Pliks es nācu no mātes klēpja, un pliks es turp atgriezīšos!”: māksla nomirt patērētāju sabiedrībā

Today, we do not talk about death very much; if we do, we talk about mass death in media which is an estranged tragedy and does not appeal to us. On the other hand, the spirit of the time which we live in tries to prevent us from aging mostly by using consumerist philosophy, thus placing death and dying, and, especially, the consciousness of our own death in the grey zone. In this article, we aspire to sketching the main attitudes toward death in consumerist society, using theories of consumerism and also Google Analytics in order to define the lifestyle of the contemporary consumerist. Then, with some examples from the point of view of philosophy of religion and also keeping in mind the theology of Book of Job from the perspective of philosophy of religion, we will try to find an answer to the question – “how does the theology of the Book of Job or the interpretations thereof can help us to form our style of death?” Two main ideas are synthesised in the course of the article: firstly, consumerist lifestyle can be characterised as “desire for the desire”, while in Book of Job, when it is read from the consumerist’s perspective, one can see the repeating of faith, which is also an essential part of the theology of Soren Kierkegaard. Thus, the synthesis of these conclusions can construct consumer’s “death style”, which can be defined as “desire for the everlasting”.
Potencial hidromineral dos aquíferos do estado de São Paulo
Authors: GARPELLI Lia Nogueira , GASTMANS Didier
Published: December 2020

O estado de São Paulo lidera a produção brasileira de água mineral. Devido ao seu complexo arcabouço hidrogeológico, composto por vários aquíferos sedimentares e fraturados, as águas minerais apresentam diferentes características hidrominerais. Assim, o principal objetivo foi avaliar o potencial hidromineral dos aquíferos paulistas, fundamentado pelo Código de Águas Minerais (CAM) e legislações internacionais correlatas, a partir de uma base de dados pública de laudos analíticos de 276 poços de águas subterrâneas da Companhia Ambiental do Estado de São Paulo (CETESB). Baseado nas concentrações de Sólidos Totais Dissolvidos (STD), observou-se que as águas subterrâneas possuem grau variável de mineralização, sendo as águas mais mineralizadas associadas aos sistemas aquíferos Serra Geral (SASG), Tubarão (SAT) e Bauru (SAB). Entretanto, apenas 8,7% das águas se enquadrariam como mínimo e baixo teores de STD pela legislação dos Estados Unidos. Similarmente, apenas duas amostras seriam enquadradas como muito pouco mineralizadas e 81,5% em pouco mineralizadas pela legislação europeia. Pelas classificações dispostas pelo CAM, as amostras foram caracterizadas pela temperatura, predominantemente, como frias e hipotermais, e uma pequena parcela como mesotermais e hipotermais. As águas mais frias prevaleceram no aquífero Cristalino (SAC), enquanto as águas de maiores temperaturas ocorreram no Guarani (SAG). Todo os aquíferos possuíram potencial hidromineral pela classificação química, pela concentração de flúor, seguido em ordem decrescente, pelo lítio no SAC, o vanádio no SASG, a alcalina bicarbonato no SAT, sulfato e selênio de forma mista no SAT e SASG.
