Effect of Corneal Tilt on the Determination of Asphericity
Authors: Consejo Alejandra , Fathy Arwa , Lopes Bernardo T. , Ambrósio Renato , Abass Ahmed
Published: November 2021

Purpose: To quantify the effect of levelling the corneal surface around the optical axis on the calculated values of corneal asphericity when conic and biconic models are used to fit the anterior corneal surface. Methods: This cross-sectional study starts with a mathematical simulation proving the concept of the effect that the eye’s tilt has on the corneal asphericity calculation. Spherical, conic and biconic models are considered and compared. Further, corneal asphericity is analysed in the eyes of 177 healthy participants aged 35.4 ± 15.2. The optical axis was determined using an optimization procedure via the Levenberg–Marquardt nonlinear least-squares algorithm, before fitting the corneal surface to spherical, conic and biconic models. The influence of pupil size (aperture radii of 1.5, 3.0, 4.0 and 5.0 mm) on corneal radius and asphericity was also analysed. Results: In computer simulations, eye tilt caused an increase in the apical radii of the surface with the increase of the tilt angle in both positive and negative directions and aperture radii in all models. Fitting the cornea to spherical models did not show a significant difference between the raw-measured corneal surfaces and the levelled surfaces for right and left eyes. When the conic models were fitted to the cornea, changes in the radii of the cornea among the raw-measured corneal surfaces’ data and levelled data were not significant; however, significant differences were recorded in the asphericity of the anterior surfaces at radii of aperture 1.5 mm (p < 0.01). With the biconic model, the posterior surfaces recorded significant asphericity differences at aperture radii of 1.5 mm, 3 mm, 4 mm and 5 mm (p = 0.01, p < 0.01, p < 0.01 & p < 0.01, respectively) in the nasal temporal direction of right eyes and left eyes (p < 0.01, p < 0.01, p < 0.01 & p < 0.01, respectively). In the superior–inferior direction, significant changes were only noticed at aperture radii of 1.5 mm for both right and left eyes (p = 0.05, p < 0.01). Conclusions: Estimation of human corneal asphericity from topography or tomography data using conic and biconic models of corneas are affected by eyes’ natural tilt. In contrast, the apical radii of the cornea are less affected. Using corneal asphericity in certain applications such as fitting contact lenses, corneal implant design, planning for refractive surgery and mathematical modelling when a geometrical centre of the eye is needed should be implemented with caution.
Destination Resilience and Innovation for Advanced Sustainable Tourism Management: A Bibliometric Analysis
Authors: Della Corte Valentina , Del Gaudio Giovanna , Sepe Fabiana , Luongo Simone
Published: November 2021

Over the years, literature on the topic of destination resilience has gained increasing attention in different fields (strategic management; sociology; etc.). Therefore, the potentiality of resilience in the tourism field has stimulated the definition and the implementation of strategies, policies, and activities addressed to mitigate risks and seize opportunities through open innovation attitudes in times of crisis. This work aims to contribute to the debate on tourist destination resilience by proposing a conceptual framework of destination resilience and open innovation based on a bibliometric analysis. Moreover, this article is intended as a starting point for a wider discussion of factors that contribute to destination resilience and therefore provides the basis to develop a toolkit of matrixes and approaches. Findings reveal that resilience assessment, as well as in terms of performance, remain undiscovered. Moreover, the present research poses some unresolved questions, shaping interesting future research directions.

Foreign Direct Investment and Environmental Quality: Revisiting the EKC in Latin American Countries
Authors: Ochoa-Moreno Wilman-Santiago , Quito Byron Alejandro , Moreno-Hurtado Carlos Andrés
Published: November 2021

In this study we aim to test the effects of foreign direct investment (FDI) on carbon emissions (CO2) in 20 Latin American countries during the period of 1990–2018. Based on the atlas method of the World Bank, we divided the countries into three groups according to their real gross national income per capita: high-income, upper-middle-income and lower-middle-income countries. We used cointegration techniques and causality tests to evaluate the relationship between the variables. To assess the strength of the cointegration vector, we applied the dynamic ordinary least squares (DOLSs) model for individual countries and the dynamic panel ordinary least squares (PDOLSs) model for groups of countries. The results suggest that the entry of FDI into Latin American (LA) countries increases CO2 emissions, affecting the environmental quality. These findings disagree with the environmental Kuznets curve (EKC) hypothesis but, in contrast, they are in line with the pollution haven hypothesis (PHH). Moreover, we show evidence in long-term equilibrium relationship between FDI input and CO2 emissions, which is not the case for the short-term equilibrium. Some additional results suggest that FDI flows do not cause the CO2 emissions in LA countries. The empirical findings suggest policymakers to design policies to “the second-best theory”, targeting FDI flows to their economies to solve economic problems in the short term, but thereafter they may guarantee the reduction in environmental pollution, based on environmentally responsible FDI and stronger regulations. In other words, the transition from a pollution haven to the applicability of the environmental Kuznets curve (EKC). This study contributes with scarce empirical evidence for LA countries in this issue.

Published: November 2021

One part of the tree, namely the leaves, which grow on the branches, has several types of leaves consisting of 4 shapes, ranging from circular shapes, elongated shapes, and some even have a finger shape. Often we mistake the shapes of these leaves. This study discusses the classification of leaves based the shape of the leaf bones using the Convolutional Neural Network, which is used to classify data that has been labeled using one of the methods, namely supervised learning. The purpose of this method is to classify a variable into the variables that have been listed. The goal is to classify leaves based on leaf shape to implement a Convolutional Neural Network algorithm model for leaf classification based on bone shape, which will produce an accuracy value. Accuracy values are obtained from conducting experiments at the training and trial stages. So it can be concluded using the epochs parameter of 30 and a batch size of 128, using ReLU and Softmax activations. The results obtained for the accuracy value for training are 98.52%, while the validation is 89.06%.

Published: November 2021

Background: Obesity in children and adolescents has increased exponentially around the world. Furthermore, the COVID-19 pandemic has led to a higher pediatric obesity rate. The excess adipose tissue generates a dysregulation of adiponectin, ghrelin, and leptin, among others. Metabolic alterations can develop cardiovascular disease, dyslipidemias, arterial hypertension, type 2 diabetes mellitus, nonalcoholic fatty liver disease, sleep disorders, and higher risk of COVID-19 severity. Obesity has different therapeutic approaches such as behavioral weight loss programs, pharmacologic treatments, and surgical procedures. Therefore, timely diagnosis and treatment are important to decrease the mortality in obesity among pediatric population.

Introducción: El presente artículo tiene como objetivo realizar una revisión sobre prescripción social y confianza en torno al despliegue de las prestaciones sociales en los Centros del Adulto Mayor (CAM) del Seguro Social de Salud (EsSalud) durante la emergencia sanitaria por COVID-19. EsSalud en sus 126 CAM brinda prestaciones sociales a personas adultas mayores, esto es, actividades para el uso del tiempo libre que están ligadas a prescripción social; que al decretarse la emergencia sanitaria viraron a la modalidad virtual. La experiencia frente a la pandemia señala que la confianza en las instituciones varía en torno a las decisiones tomadas; ayudando a mantenerla, medidas como transparencia, colaboración entre interesados, entre otras; aspectos de interés si se desea que la población siga pautas sanitarias brindadas. En ese sentido, planteamos que las actividades de prescripción social pueden contribuir a la mejora de la confianza, debiendo realizarse investigación vinculante para la toma de decisiones.

Sin embargo, a nivel superior el acceso y permanencia a la educación para personas con discapacidad continúa siendo un reto. Se presenta una investigación cualitativa con metodología de estudio de caso, cuyo objetivo es conocer el proceso de inclusión educativa de una alumna con discapacidad motriz, estudiante en una escuela rural. Para tener un panorama integral del caso, se utilizó una encuesta sociodemográfica, entrevista estructurada del historial clínico, escala estimativa del INDEX de inclusión de Booth y Ainscow (2000) y una entrevista semi estructurada sobre la inclusión educativa.  A través de la información obtenida, se evidencia la necesidad del fortalecimiento de las políticas a nivel superior, para eliminar las barreras de acceso y traslado, así como la implementación de una cultura inclusiva que erradique las prácticas discriminatórias.
Perú: lucha por la integración pluricultural y el peligro de la modernidad en la educación
Authors: Felix Erik
Published: November 2021

The present research aims to reflect on what to do in the educational community in general. This is to integrate all students in their own and broad pedagogical policy, listening to each community's voices, and of course, their problems. For this, a brief historical tour was made, revealing the main educational policies from the founding of the Republic to the present, highlighting the desire of successive governments to implement foreign pedagogical models in their erroneous attempt to "modernize" the nation. Likewise, it was analyzed how this modernization process does not provide real solutions to the Peruvian pedagogical universe in the current neoliberal context. On the contrary, it is exclusive and outside the national context, where we must identify ourselves as a multicultural country, with different languages, customs, stories, traditions, etc.

Arte y obra de los hombres primitivos en el Altiplano. Descripción de las manifestaciones pictográficas de Oqhoruni en la comunidad de Isivilla en Puno
Authors: Dávila-Quispe Rudy Oswaldo
Published: November 2021

From a qualitative study model, observation and documentary analysis, the aim is to describe the iconographic figures of the pictographic manifestations of Oqhoruni in the Isivilla community of the Corani-Carabaya district in Puno. The results show that the description of said pictographic expressions from some scenes such as anthropomorphic, zoomorphic and geometric figures, mostly highlight strong hunting scenes, the chaco and the caicu. In that odd one, it especially draws the attention of geometric figures, vertical parallel lines and painted in colors of dark red, orange, yellow and white. Within these manifestations, it can be concluded that there is no doubt that the art and work of primitive men in the highlands have not only reflected and left on the rocky surfaces real activities that surrounded them in the environment where they lived thousands of years ago . But in addition, a strong insistence to be immortalized in the enchantments of Oqhoruni is seen in the distance.

The use of pesticides is becoming an indispensable technique in most agricultural practices, regardless of the level of development of the country. Currently, the pesticides used are often less toxic and more specific and are based on insect physiology. Recent studies indicate that pesticide intoxication induces oxidative stress. This work aims to study the neurobehavioral consequences of the administration of two insecticides currently widely used in agriculture: spirotetramat (an inhibitor of lipid synthesis in insects) and the ethanolic extract of Citrullus colocynthis (a plant endemic to the Algerian Sahara) and the ethanolic extract of Cleome arabica (Capparidaceae) The different behavioral tests (elevated cross maze, open fields and forced swimming) show that the have a significant impact on the degree of anxiety of rodents.These products significantly influence the biochemical parameters (blood sugar, cholesterol, triglycerides, urea, creatinine), the hormone Adreno CorticoTropic Hormone, acetylcholine esterase,

Conventionally, the radius of curvature of crystal planes in a wafer is measured by position-dependent X-ray diffraction (XRD) along a particular diagonal direction of the wafer. However, we show herein that this method is not reliable for assessing the wafer’s real three-dimensional curvature. Using commercial 2 inch 4H-SiC, GaN, AlN, and β-Ga2O3 wafers, we demonstrate that the choice of the diagonal direction along which the position-dependent XRD was acquired strongly affects not only the apparent radius of curvature but also whether it is convex or concave.
Annealing effect of absorber layer on SnS/CdS heterojunction band alignments

Published: November 2021

The effect of annealing on the physical properties of an SnS thin film and also on SnS/CdS heterojunction band alignment was studied. Vacuum annealing has greatly improved the crystalline quality of SnS and an average grain size of 1.6 μm was achieved. Sulfur-rich secondary phases observed on the surface of as-grown SnS thin film were eliminated after vacuum annealing, resulting in a decrease of the resistivity and an increase of the carrier concentration of the film. A maximum hole mobility of 17 cm2 V−1 s−1 was obtained for SnS thin films annealed at 400 °C. A transition of SnS/CdS heterojunction from “spike” type to “cliff” type was observed when the vacuum annealed SnS thin film was post-air-annealed at 200 and 250 °C. The band alignment of SnS/CdS heterojunction could be adjustable between “spike” type to “cliff” type via vacuum annealing followed by post-air-annealing.
Structural study of single Shockley stacking faults terminated near substrate/epilayer interface in 4H-SiC
Authors: Nishio Johji , Ota Chiharu , Iijima Ryosuke
Published: November 2021

Structural analysis is carried out of a single Shockley stacking fault (1SSF) that terminates near the substrate/epilayer interface and originally expanded from a basal plane dislocation (BPD) segment near the epilayer surface of 4H-SiC. The characteristic zigzag structure is found for the partial dislocations (PDs), with microscopic connecting angles of almost 120°. It has been suggested that the microscopic construction of PDs might be limited by the Peierls valley. The termination line near the substrate/epilayer interface was found to have 30° Si-core and 90° Si-core PDs. This combination is the same as that found near the surface of the epilayer in commonly observed 1SSFs. Penetrating BPDs of this kind were also found experimentally for the first time. For the currently proposed charts for the 1SSF expansions, photoluminescence imaging during UV illumination is one of the nondestructive analysis methods that can provide the structural information and expected expansion shapes of the 1SSFs.

High-quality AlN with uniform in-plane strain has been attempted with preset strain modulation on nano-patterned AlN templates (NPATs). It is found that this strain preset frame can effectively improve both the tilt and twist features of AlN on NPATs, further greatly decreasing threading dislocation density. More importantly, the AlN epilayer after completing coalescence can maintain the in-plane uniform compressive strain. Adopting AlN templates achieved in this scheme, the chip-on-wafer light output power (LOP) of AlGaN light-emitting diode (LED) reaches 10.2 mW at 100 mA with single emission peak at 280 nm, which increases by 22.3% than the LOP of LED device without adopting this strain preset frame.
Una lettera di Paolo Bajnotti a Cristoforo Negri nel contesto dell’esplorazione del Mar Morto nel XIX secolo
Authors: Pappalardo Carmelo
Published: November 2021

A letter in the archives of the Italian Geographical Society in which Paolo Bajnotti, an italian diplomat who had resided in Egypt, informs Cristoforo Negri about his trip to Palestine in 1869, before moving to Galaz for a new assignment, and about how he visited the Dead Sea thanks to the guidance of a Franciscan scholar who reported that he had personally observed that over the last ten years the level of the Dead Sea had dropped by about 95 cm, provides the opportunity for a historical overview of the exploration of the Jordan Valley from Lake Tiberias to the Gulf of Aqaba during the 19th century. What might seem to be a mere curiosity is in fact part of a very significant issue that was controversial among the geographers and cartographers of the time, as is clearly shown in Negri’s speech at the meeting of the Società Geografica Italiana on March 13th 1870. The level of the Dead Sea and the level of the Sea of Galilee, the resulting difference in height that the River Jordan has to cover with a significant average gradient, the lack of a rise in the level of the Dead Sea despite the absence of an estuary were questions that in the mid-19th century were still waiting for an answer supported by scientific data and free of pious or pseudo-scientific overtones. A numerous series of expeditions - some improvised, others well organized - gave some answers to these issues, removing any doubt and establishing that the entire hydrologic basin was significantly below the level of the Mediterranean, that the Jordan did not have a strong slope because it was very meandering, and that the Dead Sea’s level was regulated by the strong amount of evaporation that occurred throughout the year.
Circularity within the construction sector: organisational models based on re-manufacturing
Authors: Dalla Valle Anna , Atta Nazly , Macrì Luca , Ratti Sara
Published: November 2021

Unlike other industrial sectors that already apply re-manufacturing, the construction sector is slow to experiment with these sustainable practices. Hence, this paper introduces key results of the Re-NetTA project, conducted at Politecnico di Milano and funded by Fondazione Cariplo (2018-0991), which intends to outline the conditions necessary to activate circular processes in the field of tertiary construction. In order to extend the life of construction products, the paper proposes three circular models based on re-manufacturing. Developed with stakeholders and experts in an inter-sectoral and multidisciplinary approach, the proposed models represent a contribution towards sustainable design and organisational practices of construction products.

Published: November 2021

Fuel-consumption reduction in the truck industry is significantly beneficial to both energy economy and the environment. Although estimation of drag forces is required to quantify fuel consumption of trucks, computational fluid dynamics (CFD) to meet this need is expensive. Data-driven surrogate models are developed to mitigate this concern and are promising for capturing the dynamics of large systems such as truck platoons. In this work, we aim to develop a surrogate-based fluid dynamics model that can be used to optimize the configuration of trucks in a robust way, considering various uncertainties such as random truck geometries, variable truck speed, random wind direction, and wind magnitude. Once trained, such a surrogate-based model can be readily employed for platoon-routing problems or the study of pavement performance.

Достижение прочных стратегических позиций лидера на глобальных рынках допустимо только за счет интенсивного развития оригинальных и устойчивых преимуществ. Конечная задача каждого предприятия – успех в конкурентной борьбе. Победа эта не единовременная, не случайная, а как логичный результат непрерывных и квалифицированных устремлений деятельности компании. Достигается она или нет, зависит от конкурентоспособности товаров и услуг компании, т.е. от того, в какой степени они лучше по сопоставлению с продуктами-аналогами и предложениями прочих компаний. В статье рассматриваются основные стратегии маркетинга и использование их в разных ситуациях; рассмотрены инструменты маркетинга товарной политики; приведена характеристика инструментов маркетинга.

В статье сделан вывод о том, что эффективность управления рисками зависит от методов контроля и своевременного оповещения обо всех изменениях в программе управления рисками организации. Постоянный аудит как в самой системе управления рисками, так и в соответствии с принятыми стандартами, необходим для выявления вопросов, требующих дополнительного вмешательства.
УПРАВЛЕНИЕ РЕГИОНАМИ ФЕДЕРАТИВНОЙ СТРАНЫ
Authors: Булгучев М.Х.
Published: November 2021

Если в прошлом население какой-либо суверенной страны строило свою государственность: укрепляло границы, развивало язык, повышало национальную культуру, обеспечивало развитие и безопасность экономики, то в последние десятилетия в мире, особенно в Европе, наблюдаются обратные процессы – стирание границ между странами, изучение в школах 2 – 3 языков соседних народов, единая валюта и общая безопасность.
Такое общежитие народов в какой-то мере можно сравнить с понятием «Федерация».
В последнее время учёные всё больше внимания уделяют анализу взаимоотношений субъектов федерации как между собой, так и с Центром.

Evaluación de almidones de arroz cubanos como adhesivo para la restauración de documentos: fuerza de adhesión y flexibilidad
Authors: Díaz Navarro Janet , Baró Valle Inés , Borrego Alonso Sofía Flavia
Published: November 2021

El uso de adhesivos vegetales en diferentes procesos de conservación es una tradición entre los restauradores de papel de origen oriental y de otros países. Los adhesivos de almidón son derivados de raíces y semillas tales como maíz, papa, yuca, arroz y trigo. Los más utilizados en conservación son los de trigo y arroz. En este trabajo se valora la conveniencia del uso de almidón de arroz procedente de variedades de plantas cubanas para tratamientos de restauración de obras sobre papel. Se evaluó la flexibilidad, fuerza de adhesión y estabilidad en el tiempo en probetas elaboradas de papel tratado con almidón de arroz. Dos muestras de almidón purificado a partir de arroz cubano con porcentajes intermedios de amilosa fueron comparadas con muestras de adhesivos comerciales (almidón de trigo, arroz y metilcelulosa). El uso de almidones de arroz cubanos para la restauración del patrimonio documental permite sustituir la importación de adhesivos que resultan extremadamente caros.

Volunteer Service after the Volunteer Service: The Sector of Employment and Veteran Volunteering
Authors: Baktir Yusuf , Sillah Aminata
Published: November 2021

The purpose of this article is to illustrate how changes in institutional environment may impact veteran volunteering. We argue that veterans are likely to adapt to new institutional environment as they start working for different sectors such as private, public and nonprofit. Findings suggest that regardless of the sector of employment, veterans are more likely to volunteer than non-veterans. Additionally, veterans in the federal government, nonprofit sector and those who are self-employed are more likely to volunteer than veterans working in the private sector. However, no difference exists between veterans in the local government, state government and the private sector. Inversely, state and local government employment increases the likelihood of volunteering for the non-veterans, but federal employment has no influence. This study aims to fill the gap in our understanding of institutional environment and its impact on veteran volunteering. Implications for practitioners and future research are discussed at the end.
How Successful is Participatory Budgeting in Promoting Social Equity? Evidence from New York City
Authors: Kuenneke Ashley , Scutelnicu Gina
Published: November 2021

This study examines how successful the NYC's participatory budgeting (PB) has been in promoting social equity in its city council districts. Drawing on secondary data coming from NYC council data and American Community Survey, this study specifically examines how successful PB has been in engaging under-represented groups in its decision-making process, and in allocating funds equitably. Findings suggest that districts with a higher percentage of Asian-American and mixed race residents have a higher percentage of PB voters. The study finds that African–Americans, residents of Hispanic origin and women were not significant predictors of PB voters. Additionally, results indicate that districts with a higher percentage of people living below the poverty level and more Asian-American residents allocate more funds to PB projects. Other under-represented groups such as foreign born population and youth between 14 and 18 years of age did not have a statistically significant relationship with neither PB voters nor funding.
