Published: February 2021

Amaç: Glokomun semptom vermemesi, görme kaybı oluşana dek tanı konamamasına ve tedavide geç kalınmasına yol açmaktadır. Bu durumun en önemli nedeni farkındalığın düşük olmasıdır. Bu çalışmada, Aile hekimliği polikliniğine herhangi bir sebeple başvuran 40 yaş üzeri hastalarda glokom farkındalığını ve sıklığını belirlemek amaçlandı. Gereç ve Yöntem: Kesitsel nitelikteki çalışmaya, Haziran 2019-Ekim 2019 tarihleri arasında herhangi bir sebeple Aile Hekimliği polikliniğine başvuran 40 yaş üzeri hastalar dahil edildi. Katılımcılara, sosyo-demografik ve klinik özelliklerini, glokom farkındalığını değerlendirmek için 15 sorudan oluşan bir anket uygulandı.Hastaların göz polikliniğinde, aynı uzman doktor tarafından refraksiyon kusurları, göz içi basıncı(GİB), santral kornea kalınlığı(SKK) ölçüldü ve biyomikroskopik muayeneleri yapıldı. Glokom tespit edilen ve edilmeyen hastalar risk faktörleri ve farkındalık durumu açısından değerlendirildi. Bulgular: Çalışmaya dahil edilen 206 hastanın %62,6'sı kadın, %37,4'ü erkekti. Yaş ortalaması 58,3±10,0 yıldı. Katılımcıların %6,3'ünde glokom tespit edildi. Glokom muayenesi olmadığını belirtenlerin %4,8'inde, glokom muayenesi olduğunu belirtenlerin %22,2'sinde glokom tespit edildi. Hastaların %90,3'ü glokomun ne olduğunu ve belirtilerin bilmediğini,%91,3'ü glokom muayenesi olmadığını belirtti. Glokomun ne olduğunu bilenlerin %57,9'u göz doktorundan öğrendiğini belirtti. Sigara kullanımı açısından gruplar arasında anlamlı farklılık saptandı (p=0,02). Glokomu olan 13 hastanın hiç biri sigara içmiyordu. Glokom muayenesi olduğunu belirtenlerde, muayene olmayanlara göre, glokomun ne olduğunu ve belirtilerini bilenlerde bilmeyenlere göre glokom sıklığı anlamlı olarak daha fazla bulundu (sırasıyla, p=0,01, p=0,001 ve p=0,004). Yaş, ailede glokom öyküsü ve glokom muayenesi olma durumu ile glokom farkındalığı arasında anlamlı ilişki tespit edildi (sırasıyla, p=0.01, p=0.01 ve p=0.001). Sonuç:Görme kaybına neden olan, ancak erken tanı ve tedavi ile kontrol altına alınabilen glokom için toplumda farkındalığı artırma ve hastalık kontrolünde göz hekimi ve aile hekimlerinin bilgilendirme ve düzenli takipleri en önemli girişimdir.
Das Verb „brauen“ im Helgoländischen: mit Beibehaltung der starken Flexion und reich entwickelter Semantik
Authors: Århammar N.
Published: February 2021

The verb „brew“ in the North Frisian dialect of the North Sea island of Heligoland is in two respects remarkable: first it has retained its original strong inflection (section 1) and secondly it developed a number of special meanings during the 19/20th century (section 2). I have tried to demonstrate how this great diversity came about: The starting point for thesemantic development was probably the analogy ʽbrew kettleʼ (for beer brewing) ~ ʽsteam boilerʼ (of steam-boats). In a small seafaring nation a shift of meaning from ʽbrew (beer)ʼ → ʽdrive (a ship)ʼ may seem rather natural; less so the further steps via *ʽmove in generalʼ → ʽwalk briskly, runʼ and so on (→ ʽlive, keep house, manage to get on well (as a single)ʼand ʽbe busy, workʼ etc.). Sense 8. of the dictionary entry, a figurative meaning, stands apart, namely ʽconcoct, contrive, prepare, bring about, causeʼ: spec. evil, mischief, trouble, woe (OED). It is noted that this sense was developed in most Germanic languages and it probably represents a much older sprout on the helig. brau-tree than do the senses 2. to 7. Insection 3, I deal with the helig. idiom Bin brau ʽto bring into disorderʼ and the helig.-wfris. parallel uun Bin ~ yn ʼe/ʼt bûn ʽin disorderʼ. – In the appendix the revised and enlarged word article brau with its prefix compounds is presented

The paper identifies and analyzes the features of the mechanism of field emission in the tunneling microscope probe – indium antimonide quantum dot system in the temperature range of 23—150 °C. The analysis of the tunneling CVCs made it possible to conclude that there are different mechanisms of electron transfer from the metal probe of the tunneling microscope and the field emission of electrons through discrete energy levels of the indium antimonide quantum dot at different temperatures.
Convalescent Plasma for the Prevention and Treatment of COVID-19: A Systematic Review and Quantitative Analysis
Authors: Peng Henry T , Rhind Shawn G , Beckett Andrew
Published: February 2021

Background

The COVID-19 pandemic, caused by a novel coronavirus termed SARS-CoV-2, has spread quickly worldwide. Convalescent plasma (CP) obtained from patients following recovery from COVID-19 infection and development of antibodies against the virus is an attractive option for either prophylactic or therapeutic treatment, since antibodies may have direct or indirect antiviral activities and immunotherapy has proven effective in principle and in many clinical reports.

Objective

We seek to characterize the latest advances and evidence in the use of CP for COVID-19 through a systematic review and quantitative analysis, identify knowledge gaps in this setting, and offer recommendations and directives for future research.

Methods

PubMed, Web of Science, and Embase were continuously searched for studies assessing the use of CP for COVID-19, including clinical studies, commentaries, reviews, guidelines or protocols, and in vitro testing of CP antibodies. The screening process and data extraction were performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Quality appraisal of all clinical studies was conducted using a universal tool independent of study designs. A meta-analysis of case-control and randomized controlled trials (RCTs) was conducted using a random-effects model.

Results

Substantial literature has been published covering various aspects of CP therapy for COVID-19. Of the references included in this review, a total of 243 eligible studies including 64 clinical studies, 79 commentary articles, 46 reviews, 19 guidance and protocols, and 35 in vitro testing of CP antibodies matched the criteria. Positive results have been mostly observed so far when using CP for the treatment of COVID-19. There were remarkable heterogeneities in the CP therapy with respect to patient demographics, donor antibody titers, and time and dose of CP administration. The studies assessing the safety of CP treatment reported low incidence of adverse events. Most clinical studies, in particular case reports and case series, had poor quality. Only 1 RCT was of high quality. Randomized and nonrandomized data were found in 2 and 11 studies, respectively, and were included for meta-analysis, suggesting that CP could reduce mortality and increase viral clearance. Despite promising pilot studies, the benefits of CP treatment can only be clearly established through carefully designed RCTs.

Conclusions

There is developing support for CP therapy, particularly for patients who are critically ill or mechanically ventilated and resistant to antivirals and supportive care. These studies provide important lessons that should inform the planning of well-designed RCTs to generate more robust knowledge for the efficacy of CP in patients with COVID-19. Future research is necessary to fill the knowledge gap regarding prevention and treatment for patients with COVID-19 with CP while other therapeutics are being developed.
Digital Health Interventions in Prevention, Relapse, and Therapy of Mild and Moderate Depression: Scoping Review
Authors: Tokgöz Pinar , Hrynyschyn Robert , Hafner Jessica , Schönfeld Simone , Dockweiler Christoph
Published: February 2021

Background

Depression is a major cause for disability worldwide, and digital health interventions are expected to be an augmentative and effective treatment. According to the fast-growing field of information and communication technologies and its dissemination, there is a need for mapping the technological landscape and its benefits for users.

Objective

The purpose of this scoping review was to give an overview of the digital health interventions used for depression. The main goal of this review was to provide a comprehensive review of the system landscape and its technological state and functions, as well as its evidence and benefits for users.

Methods

A scoping review was conducted to provide a comprehensive overview of the field of digital health interventions for the treatment of depression. PubMed, PSYNDEX, and the Cochrane Library were searched by two independent researchers in October 2020 to identify relevant publications of the last 10 years, which were examined using the inclusion and exclusion criteria. To conduct the review, we used Rayyan, a freely available web tool.

Results

In total, 65 studies were included in the qualitative synthesis. After categorizing the studies into the areas of prevention, early detection, therapy, and relapse prevention, we found dominant numbers of studies in the area of therapy (n=52). There was only one study for prevention, 5 studies for early detection, and 7 studies for relapse prevention. The most dominant therapy approaches were cognitive behavioral therapy, acceptance and commitment therapy, and problem-solving therapy. Most of the studies revealed significant effects of digital health interventions when cognitive behavioral therapy was applied. Cognitive behavioral therapy as the most dominant form was often provided through web-based systems. Combined interventions consisting of web-based and smartphone-based approaches are increasingly found.

Conclusions

Digital health interventions for treating depression are quite comprehensive. There are different interventions focusing on different fields of care. While most interventions can be beneficial to achieve a better depression treatment, it can be difficult to determine which approaches are suitable. Cognitive behavioral therapy through digital health interventions has shown good effects in the treatment of depression, but treatment for depression still stays very individualistic.

Authors: Schroeder Kristin , Maiarana James , Gisiri Mwitasrobert , Joo Emma , Muiruri Charles , Zullig Leah , Masalu Nestory , Vasudevan Lavanya
Published: February 2021

BACKGROUND

There is a 60% survival gap between children diagnosed with cancer in low- and middle-income countries (LMICs) and those in high-income countries. Low caregiver knowledge about childhood cancer and its treatment results in presentation delays and subsequent treatment abandonment in LMICs. However, in-person education to improve caregiver knowledge can be challenging due to health worker shortages and inadequate training. Due to the rapid expansion of mobile phone use worldwide, mobile health (mHealth) technologies offer an alternative to delivering in-person education.

OBJECTIVE

The aim of this study is to assess patterns of mobile phone ownership and use among Tanzanian caregivers of children diagnosed with cancer as well as their acceptability of an mHealth intervention for cancer education, patient communication, and care coordination.

METHODS

In July 2017, caregivers of children <18 years diagnosed with cancer and receiving treatment at Bugando Medical Centre (BMC) were surveyed to determine mobile phone ownership, use patterns, technology literacy, and acceptability of mobile phone use for cancer education, patient communication, and care coordination. Descriptive statistics were generated from the survey data by using mean and SD values for continuous variables and percentages for binary or categorical variables.

RESULTS

All eligible caregivers consented to participate and completed the survey. Of the 40 caregivers who enrolled in the study, most used a mobile phone (n=34, 85%) and expressed high acceptability in using these devices to communicate with a health care provider regarding treatment support (n=39, 98%), receiving laboratory results (n=37, 93%), receiving reminders for upcoming appointments (n=38, 95%), and receiving educational information on cancer (n=35, 88%). Although only 9% (3/34) of mobile phone owners owned phones with smartphone capabilities, about 74% (25/34) self-reported they could view and read SMS text messages.

CONCLUSIONS

To our knowledge, this is the first study to assess patterns of mobile phone ownership and use among caregivers of children with cancer in Tanzania. The high rate of mobile phone ownership and caregiver acceptability for a mobile phone–based education and communication strategy suggests that a mobile phone–based intervention, particularly one that utilizes SMS technology, could be feasible in this setting.

Obstacles of providing exclusive breastfeeding among working mothers using social-ecological theoryBackground: The coverage of exclusive breastfeeding (EBF) in Indonesia was increased to 38% but it was lower than the Millennium Development Goals (MDGs) target (80%). One of the influence factors is to return to work. Society assumed that a mother who stays at home more successful to provide EBF than working mothers. A previous study indicated that some obstacles become early cessation factors among working mothers.Objective: To explore the obstacle of breastfeeding using social-ecological theory.Methods: Qualitative research inquiry based on phenomenology design. Informants were chosen through purposive sampling. Inclusion criteria were working mothers who succeeded provide exclusive breastfeeding, had children age 6-24 months, lived, and formally worked at Manado. Data triangulation was conducted through in-depth interviews with the manager/supervisor/colleague. Data collected using in-depth interviews and observation.Results: A total of twelve informants have interviewed consists of six working mothers and six triangulation informants. The result indicated that lack of confidence was related to providing exclusive breastfeeding. This is caused by family influence, culture, health provider, and lack of awareness from the working place. A support group was the main factors that influence the mother to overcome all obstacles.Conclusions: The main obstacles for working mothers to provide EBF come from interpersonal factors that determined by other factors: intrapersonal, organizational, community. Therefore working mothers need breastfeeding preparation since early pregnancy to decrease breastfeeding obstacles.

Controversias sobre vulnerabilidad ante el riesgo minero en el río Sonora, México
Authors: Orozco Martínez Yuriria , Rodríguez Gámez Liz Ileana
Published: February 2021

El objetivo de la investigación es analizar, desde varios puntos de vista, la percepción acerca de las vulnerabilidades debidas a la minería, considerando las posturas de diferentes actores (autoridades, activistas, asociaciones civiles, organizaciones sociales, académicos y pobladores) ante el riesgo minero en el río Sonora, México. Se emplea una metodología cualitativa que analiza los discursos de expertos y pobladores recolectados a través de entrevistas, así como de un taller de cartografía social con activistas locales. Los resultados muestran controversias entre los actores sobre la vulnerabilidad política, social, económica, física, técnica y ambiental; también indiferencias y similitudes en las posturas en torno a vulnerabilidad ideológico-cultural. La evaluación de los riesgos tecnológicos es con frecuencia politizada, porque involucra muchos intereses y valores. Por eso aquí se propone que en estos debates se asegure la participación tanto de los expertos como de los pobladores afectados. Una de las limitaciones de esta investigación es que el perfil de expertos seleccionado no incluyó al de los científicos, sino sólo a quienes Funtowicz y Ravetz llaman expertos de consultoría profesional.
El desempeño de los organismos públicos locales de derechos humanos en México, 2017-2019
Authors: Lagunes López Oscar Nicasio
Published: February 2021

El objetivo de este artículo es determinar si el desempeño de los organismos públicos locales de derechos humanos en México es eficiente o no, teniendo en cuenta los instrumentos de resolución de quejas, como las conciliaciones y las recomendaciones. La metodología empleada combina indicadores cuantitativos y cualitativos, a saber, volumen de quejas recibidas y concluidas, volumen de recomendaciones emitidas y cumplidas y si las recomendaciones cumplidas reparan o no los derechos humanos vulnerados de las víctimas. Para este fin, se analizan dos recomendaciones que las comisiones de derechos humanos de Colima (07/2017) y Chihuahua (05/2017) hicieron a las autoridades públicas. Los resultados muestran que éstas no reparan los derechos vulnerados de las víctimas, incluso después de haber sido ejecutadas, y que estos organismos han tenido un deficiente desempeño, a pesar de que se invierten en ellos cuantiosas cantidades. Por eso se concluye que las recomendaciones deben ser vinculantes y que es prioritario democratizar el proceso de elección del ombudsperson.
El desafío sociohidrológico de la cuenca del río Tijuana ante el cambio climático
Authors: Rodríguez Esteves Juan Manuel
Published: February 2021

El objetivo es analizar el contexto sociohidrológico de la cuenca del río Tijuana para enfrentar el cambio climático. Se eligió esta cuenca porque se ubica en una región semidesértica y porque la comparten México y Estados Unidos, lo que le imprime características propias. La metodología se basó en la consulta del Registro Público de Derechos de Agua, en datos de la Comisión Nacional del Agua, en proyecciones de población, en escenarios ante el cambio climático y en publicaciones académicas, con lo cual se analizó el régimen hidrológico, el crecimiento urbano y la cooperación binacional. Los resultados permiten entender la dependencia del trasvase de agua y la cooperación entre México y Estados Unidos. Una limitación del estudio radica en que se debe considerar la opinión de los habitantes para enfrentar la escasez de agua en un contexto de cambio climático, así como las estrategias que han implementado. Se concluye que, a pesar de la poca disponibilidad de agua en un contexto de cambio climático, se cuenta con mecanismos de colaboración binacional para abastecer los centros urbanos de dicho recurso de ambos países.

Authors: Herrera López Francisco F. , Fletes Ocón Héctor B. , Valdiviezo Ocampo Guillermo S.
Published: February 2021

El objetivo de este artículo es examinar los mecanismos de acción colectiva que implementaron los pequeños productores de limón persa en el Distrito de Riego San Gregorio en la región fronteriza México-Guatemala. El análisis de las estrategias que estos actores desarrollaron en las áreas de producción, difusión de conocimientos y comercialización, revela las formas en que enfrentan los retos del desarrollo territorial y los cambios en el sector alimentario. Debido a que la producción de este cítrico es un proceso reciente en el territorio, no se cuentan con estadísticas específicas y estudios previos para tomarlos como referencia, por lo que se parte de un estudio exploratorio para realizar una metodología de perspectiva cualitativa basada en la observación participante, entrevistas a distintos actores locales, conocimiento de la historia oral, aplicación de una encuesta a pequeños productores y la consulta de bases de datos. Se encontró que, para contender frente a la reestructuración del sector alimentario, los productores locales recuperaron elementos endógenos del territorio, lo que les permitió cooperar y coordinarse mediante organizaciones y la acción colectiva. Con ello adoptaron y adaptaron a sus condiciones un programa externo de introducción de un nuevo cultivo. Al ser un proceso reciente, se cuentan con pocos estudios de limón en la región.

Authors: Almanza-Avendaño Ariagor Manuel , Hernández-Brussolo Ricardo , Gómez-San Luis Anel Hortensia
Published: February 2021

El objetivo del estudio es comprender la pérdida ambigua de cinco madres de personas que sufrieron desaparición forzada en el estado de Tamaulipas, México. Se realizaron entrevistas en profundidad y se efectuó un análisis fenomenológico-interpretativo. Los resultados muestran que las madres experimentan sufrimiento social y ruptura de la vida cotidiana ante la ausencia física de su hijo y que desarrollan un mecanismo para facilitar su presencia psicológica, aunque siguen experimentando malestar. Entre los elementos del contexto que prolongan el sufrimiento, se encuentran la ineficiencia institucional y el aislamiento social. Una de las limitaciones del estudio es no haber incorporado las voces de otros miembros de la familia, de las madres que han sufrido desplazamiento forzado y de aquellas que no denuncian la desaparición por miedo. Se concluye que es necesario que el Estado reconozca su participación en el origen y en la continuidad del sufrimiento social y que sus intervenciones incorporen la dimensión psicosocial y comunitaria.

Authors: Gallego Gauna Cynthia Paola , Hernández Moreno María del Carmen
Published: February 2021

Objetivo: analizar las oportunidades y los desafíos de la producción artesanal de alimentos en Magdalena de Kino, Sonora, en un contexto en el que convergen la hiperindustrialización alimentaria y la multiplicidad de movimientos sociales que construyen alternativas alimentarias más sanas, ecológicas y justas. Metodología: con base en la teoría de los regímenes alimentarios y en el enfoque de sistemas agroalimentarios localizados, se diseñó una estrategia teórico-metodológica para identificar las dinámicas territoriales en torno a esta actividad. La información se completa con las percepciones de los productores, los consumidores y los informantes clave. Resultados: la escasez de materia prima producida localmente y la falta de cohesión social entre las unidades de producción artesanal de alimentos son los desafíos principales. Empero, el apego de dicha industria a la tradición, y la valoración que de ella se hace, inducen a los consumidores a sostener esta actividad en la región. Limitaciones del estudio: la carencia de un censo de unidades de producción artesanal de alimentos no permitió obtener una muestra estadísticamente representativa; sin embargo, ésta sí lo es de su heterogeneidad. Conclusiones: para catapultar este tipo de producción se requiere la atención multisectorial, centrada en la rehabilitación agroecológica de la producción primaria, la acción colectiva de los productores y la creación de una ruta gastronómica.

Published: February 2021

The scientific work represents a research of the cutting process in order to determine the influence of the cutting tool extensions length from the tool holder and the cutting forces that occur during processing and corresponding to different values of the removed layer on the formation of the quality of the surface layer of parts during turning. As a cutting tool, the research used a PCLNR2525M12 straight-turning tool with replaceable T15K6 carbide inserts. Steel cylindrical workpieces with a diameter D = 40 mm (steel grade - 30) were used as workpieces. Cutting was carried out at three different cutting depths: 0.4, 1, 1.5 mm. The feed rate and spindle speed throughout the experiment were constant and were equal to s = 0.1 mm/rev, n = 1000 rpm, respectively. The geometric deviations of the cutter from the theoretical cutting line were determined by mathematical modeling methods. Linear displacements formed due to the stress-strain state of the cutter were used as estimated parameters. The study presents the methodology for preparing and conducting mathematical modeling using the three-dimensional modeling system KOMPAS-3D and APM FEM module. The roughness parameters that occur during turning by cutters with different tool extension with different cutting modes were studied experimentally.

Authors: Ryzhov Sergey V. , Rylnikova Marina V. , Esina Ekaterina N.
Published: February 2021

The significant role of the gold mining industry in the development of the Russian mineral resource system determines the search for new organizational, technical and geotechnical solutions to improve the completeness and efficiency of deposit development. Most of Russia's gold deposits are in remote, sparsely populated areas, where there is a lack of energy, transport communications, and infrastructure. It is shown that the Ryabinovoe gold deposit, located in the Republic of Sakha (Yakutia), is characterized by a complex structure, relatively low occurrence of ore deposits and a widespread in the value of mineral raw materials. Features of the Ryabinovoe deposit consist in a complex structural structure and alternation of mineralized gold-bearing and low-gold-bearing or ore-free areas of various capacities and complex morphology. The main criteria for open Geotechnology have been clarified and justified. This ensures safe and efficient development of the Ryabinovoe field with the achievement of the maximum possible total discounted income and the shortest recoupment period for the project. In general, an integrated approach is the basis of the development strategy of the Ryabinovoe gold deposit. It includes increasing the level of extraction of useful components, increasing the production volume and a differentiated approach to the choice of a method for processing ores of different quality. It is shown that the achievement of rational production capacity in the complex development of the Ryabinovoe gold deposit is based on optimizing the variation of the onboard and average gold content with justification of the ratio of production capacity of the mining and processing cycle.

Published: February 2021

At designing aircraft, much attention is given to the wing, as one of the most critical elements of the airframe. It is necessary to have a clear-eyed outlook at response sequence, efficiency of various factors and calculation features on the receipt timing and quality of the result. In addition, the design of a structural element is a complex multidisciplinary task affecting various fields of science, which is complicated by the use of polymer composite materials. In the furtherance of solving the urgent task of the methods of designing of a polymer composite wing, it is necessary to determine the influence of wing deformation on the airload used in the calculation and determination of product parameters. Methods of designing of a polymer composite wing used at the initial stages and taking into account the choice of the external appearance, justification of the structural arrangement and load-bearing elements. The paper considers the flow of air over the wing of a passenger airliner and analyzes the pressure values for various flight modes. A comparison is made of the initial theoretical wing surface and deformed during flight, and the difference in loading of the considered options is determined. A future methodology of polymer composite wing design based on parametric modelling will take these results into account and make use of them.

The article analyzes the state of the phosphate raw material base in Russia and its role in the economic development of the country and in domestic agriculture especially. The problems that prevent the creation of a modern powerful phosphate production capable of satisfying the existing demands of agriculture in phosphoric mineral fertilizers are highlighted. The possible directions of the development of the phosphorus industry in the regions for the near and distant prospects are analyzed. The aim of the article is to analyze the current state of the domestic mineral resource base to produce phosphorus fertilizers, the acute shortage of which hinders the development of the country's agriculture. Actual base for research was mainly processed materials from specialized scientific articles and publicly available publications. In addition, data collected by the authors during thirty years of studying phosphorite deposits in Russia and foreign countries were involved. The analysis of published materials of leading Russian producers of phosphorus products, mining companies, databases of specialized federal and regional geological companies. It is concluded that before the country's geological services, the most important task remains to identify deposits of high-quality phosphate ores, and especially in Siberia and the Russian Far East. Significant prospects for the development of these regions are opened by the Northern Sea Route. The planned pace of its development offers unique opportunities for the economic development of the Taimyr-Anabar region, where huge resources of apatite-bearing carbonatites of the Tomptor alkaline massif and Meimech-Kotuy province are concentrated.
Anthropogenic impact on the Himalayan marmot population in Nepal

Published: February 2021

Anthropogenic impact on the Himalayan marmot population in Nepal is discussed. Above the upper border of the forest, human shares the same habitats with marmots on the alluvial terraces of river valleys. Human buildings and farmland lead to fragmentation of the marmot population, and overgrazing leads to pasture digression, worsening the food supply of these rodents. At the same time, people regularly catch marmots with loops, while, in accordance with the criteria of the IUCN Red List, the population of the Himalayan marmot in Nepal should be classified as Endangered (EN) - a very high risk of extinction in the wild.
Tick Tack Tick Tack Tick
Authors: Stuart Whipps
Published: February 2021

TTTTT research by Whipps focuses on the persistent dichotomy between art and science with the aim of disrupting it. He has opened up his art practice to inputs from the disciplines of geology, horticulture and dance, combining them in contemporary art settings to create nuanced readings. The resulting productions (artefacts, exhibitions and publications) allow for the emergence of a new sort of puzzle, which materialises through poesis in these different and often unrelated fields.

Whipps developed a co-working methodology that drew on expertise from Dr Andrew Rees (geology), University of Birmingham, Tom Brown, Head Gardener, West Dean Gardens and William Bracewell, First Soloist, Royal Ballet. This methodology was applied referencing a series of seemingly disconnected artistic nodal points, including: photographs taken at a surrealist sculpture garden in Mexico, archival material of the Scottish oil industry, stories of stolen flowers from a garden in North Wales. Using these nodes, plus others, Whipps elicited responses from the experts to inform his findings, which in turn were utilised in the production and presentation of new projections, prints and structural installation. They provided an accessible and common ground between these fields of knowledge, inviting visitors to meditate on the relationships that those fields can create when they collide in the new ways afforded by Whipps’s work.

This research has been enacted through a series of national solo art exhibitions at Spike Island, Bristol, DCA, Dundee; plus international group shows: CAPC, France, and the Irish Architecture Association, Ireland. Whipps’s research has also been disseminated in monograph publications: ‘Feeling With Fingers That See’ and ‘White Ashes Fell’ as well as in a group publication, ‘Le Musée Se Met Au Vert!’ published by Musée Des Beaux-Arts Bordeaux.

The research has been supported through two Arts Council England project grants and the Henry Moore Institute.
ISLAMIC HYPNOTHERAPY TO REDUCE PARENT'S ANXIETY TOWARDS THE FUTURE OF CHILDREN WITH AUTISTIC SPECTRUM DISORDERS
Authors: Winarsih Tri , Rohmadani Zahro Varisna
Published: February 2021

Parents of children with autism spectrum disorder (ASD) have anxiety about their children's future. This anxiety affects the psychological well-being of parents. Therefore, parents need advice to reduce their stress level. Hypnotherapy methods have been proven that those are able to reduce anxiety in various cases. For this reason, this study aims to determine the effectiveness of Islamic hypnotherapy in overcoming the fear of parents with ASD children. This study employs a pre-experimental method consisting of one group which takes treatment with the Islamic hypnotherapy method. The measurement of anxiety about the child's future was conducted by giving a scale of stress to child's future, before and after providing an intervention.The results were tested by using SPSS with Wilcoxon Signed Rank Test Z = -2.251 and Asymp. Sig. (2-tailed) = 0.024 (p<0.05), which mean that Islamic hypnotherapy can reduce the anxiety faced by parents who have autism children. Islamic hypnotherapy is capable of reducing stress because it teaches positive suggestions and and releases samplesâ€™ emotions.

Stress occurs while caring for the elderly due to several factors, namely the emotion regulation and spirituality. This study aims to examine the correlation between stress with emotion regulation and spirituality in caregivers of the elderly at Karangmojo 1 Health Center, Gunungkidul. The purposive sampling method was used to obtain data from 36 caregivers on the emotion regulation and spirituality as well as stress scale with Alpha Cronbach's reliability coefficient of 0.871, 0.921, and 0.905, respectively. The results showed that r = 0.485 and Sig. 0.012 (p <0.05). Therefore there is a correlation between stress, emotion regulation, and spirituality. This means that the higher the control of emotion and spiritual level, the lower the pressure. Furthermore, this research expects to provide input in the realm of psychology. For example, it can be used as a reference to help caregivers deal with stress by increasing their emotion regulation and spirituality skills.

Aim: This study aimed to assess uncertainty tolerances and determine the
levels of stress, anxiety, depression, and somatization in healthcare
workers who fight on the frontline, at the highest risk but seek the
least help during the pandemic. Methodology: The data of this
cross-sectional study was collected by online delivery of a short form
of Health Anxiety Inventory, Patient Health Questionnaire, the Impact of
Event Scale, and Demographic Information Form to 106 medical staff
consisting of medical doctors and nurses. At the start of the
Coronavirus outbreak in Turkey, convenient sampling was used because of
the difficulty in reaching healthcare workers. The mean scores of the
scales were compared with ANOVA between the study groups. In case of
significant differences, Bonferroni posthoc analysis was used to compare
the subgroups. Findings: A total of 106 healthcare workers consisted of
three groups: the first group; 28 workers who were temporarily not
working during data collection; 46 workers working with non-COVID 19
patients in a non-pandemic hospital; 32 subjects working with COVID 19
patients in a pandemic hospital. The working conditions, institution’s
type where physicians work for, and whether physicians previously
received psychological support showed significant differences between
the groups. Conclusions: According to our study results, healthcare
workers working with COVID 19 patients reported higher levels of
psychological symptoms. This study is crucial to reveal the significant
effects of working with COVID 19 patients on healthcare workers’ mental
health, especially in the early period of the 2020 epidemic.

Objective: The aim of this systematic review was to investigate the
effectiveness of HIFE on physiologic and psychological functions in
older adults aged ≥65 years. Methods: This systematic review was
designed according to the PEDro scale. PubMed, Web of Science and Scopus
databases were used for the systematic searching. Total 1340 studies
were identified. The full texts of these studies were examined in
respect of the study inclusion and exclusion criteria, and finally 9
studies met the criteria and were included for evaluation. Results:
Physical functions and psychosocial functions were evaluated via
questionnaires and tests. According to results of the included studies
HIFE was effective in respect of the evaluated parameters. Conclusion:
As a result of this systematic review HIFE is effective on physical
functions and hemodynamic responses but the effect on psychosocial
functions are controversially, at the same time there were no reports of
negative effects.

In 2020, we had reported one of the few cases of trisomy 13 with
ectrodactyly, a rare form of limb deformity. Herein, we report another
newborn who suffered from trisomy 13 and ectrodactyly. The patient also
possessed another unusual manifestation of trisomy 13, congenital
diaphragmatic hernia, a life- threatening pathology.
Measuring Tax Authority Monitoring
Authors: Finley Andrew R. , Stekelberg James
Published: February 2021

Despite growing academic interest in tax authority monitoring, the literature remains lacking a summary measure of realized tax authority monitoring that can be constructed from firms' publicly available financial statement information. The purpose of this study is to develop such a measure. Specifically, we view unrecognized tax benefit (UTB) releases due to settlements with the tax authority to indicate greater tax authority monitoring, and UTB releases due to lapses in the statute of limitations to indicate lesser tax authority monitoring. Among other tests, we validate a new measure of tax authority monitoring utilizing data from UTB releases by documenting its positive associations with predicted determinants of tax authority monitoring and by showing that it varies across time in expected ways. We believe our measure should be useful to future researchers studying tax authority monitoring in a variety of settings.
The Effects of Goal Publicity and Incentives on Self-Set Performance Goals

Many companies encourage employees to set their own performance goals and do not attach formal incentives to the achievement of these goals. In this environment, some organizations make employees' self-set performance goals public while other organizations do not. We predict that, due to strategic concerns induced by goal publicity and competition, making goals public will be more likely to lead employees to lowball their goals when they work under tournament incentives than under piece-rate incentives. Consistent with this prediction, our experimental results reveal that making self-set performance goals public decreases goal level under tournament incentives but has no significant effect on goal level under piece-rate incentives. Results of our study suggest that the practice of making self-set goals public is potentially more compatible with organizations with a collaborative culture than those with a competitive culture.

Measuring Multidimensional Investment Opportunity Sets with 10-K Text
Authors: Basu Sudipta , Ma Xinjie , Briscoe-Tran Hoa
Published: February 2021

We show that firms' investment opportunity sets (IOS) are multidimensional. Analyzing Form 10-K texts, we identify 445 unique keywords that predict firms' future investments during 1995–2009 and combine them into 43 underlying factors. Industry-specific factors include Bio-Pharma, Banking, Information Technology, Oil and Gas, and Retail Stores, while more general factors include Equity Intensity, Debt Intensity, Lease, Going Concern, and Acquisition. These factors form our multidimensional measures of IOS. They outperform Tobin's Q and/or industry fixed effects, in predicting future out-of-sample (2010–2015) investments and related corporate policies, and even inform incrementally over lagged dependent variables. We trace the factors' improved predictive power to their multidimensional nature, which captures IOS-related variation within and between industries, and stability in IOS that allows 10-K texts to be more informative.

Published: February 2021

This study presents the preparation of porous silicon (PS) using the photoetching technique. The light source was a laser with a 405 nm wavelength. Hydrofluoric acid, hydrogen peroxide, and ethanol were used in the process. An approach to forming PS in a selected area was also studied, in which a computational control of the laser movement was developed. A laser allows for the formation of PS in short period of time using n-type crystalline silicon (c-Si) as a substrate. Photosynthesized PS shows similar characteristics (physical and chemical) to anodized PS. Raman scattering showed a broadening of the peak centered at 525 cm−1, this behavior is related to the formation of PS. Micro-Fourier transform infrared spectroscopy showed bands related to Si-H wagging and SiH2 bending vibrations, these types of bonds were generated during the porosification process. The morphologic characteristics were defined by scanning electron microscopy (SEM) and revealed that the porous structures depend on the potency of the laser used. The topography of the surface confirms PS formation. SEM analysis demonstrated that pores with diameters of 60 and 300 nm can be obtained. Energy-dispersive x-ray spectroscopy showed an increase in oxygen in the PS due to the oxidation process following photoetching. The x-ray diffraction showed that this type of etching eliminates the induced tension in the c-Si grain edges due to PS formation.
