Purpose. The aim of this study was to determine the influence of prognostic factors on the postoperative outcome of esophageal atresia patients, taking into consideration loco-regional particular features. Methods. A retrospective analysis of the medical records of 28 patients diagnosed with esophageal atresia was conducted, using a logistic regression model. Patients had been admitted in our hospital between 2009-2014. The survival rate was recorded separately from the independent factors, such as demographic features, weight at birth, the timing of surgical treatment, co-morbidities, postoperative prognosis and management of complications. Results. According to the Spitz prognostic classification, there were 21 patients in group I (birth weight over 1500 g with no major anomaly), 3 patients in group II (birth weight less than 1500 g or major cardiac anomaly) and 4 patients in group III (birth weight less than 1500 g plus major cardiac anomaly). The mortality rate was 33% in group I, 100% in group II and 100% in group III. The mean birth weight was 2282 g ±2SD, and the mean gestational age was 31 weeks. The age at initial presentation was over 24 hours in 15 patients, with fatal outcome in 13 of them. The cardiac malformations presented as the associated anomalies with the highest risk. Surgical treatment was as follows: primary anastomosis in 21 cases, cervicostomy and gastrostomy in 6 cases, and Foker technique in 1 case. Conclusions. The analysis of this series indicated a low survival rate for this pathology in our center. Besides the prognostic factors cited in literature (low birth weight and age at birth, associated cardiac malformations), we include, as risk factors for the increased mortality, the delayed diagnosis and presentation at our tertiary center. The further refinement of a multidisciplinary approach towards this pathology would contribute to a higher survival rate and an improved result of the therapeutic management.

The infection with Helicobacter pylori (H pylori) represents an important issue of public health. Aim. Establishing the prevalence of H. pylori infection in children and presenting the cases according to the gastritis type by performing upper digestive endoscopies. Material and method. The retrospective study referred to a period of 5 years and included 1269 children evaluated by upper endoscopy to establish the H. pylori infection rate. Results. The frequency of H. pylori in the case of acute gastritis was significantly more reduced (34.78%) than in the case of chronic gastritis (54.94%). Referring to the 10 types of gastritis, the most frequent ones are purpuric (43.66%), nodular purpuric (25.93%) and nodular antral (15.84%). At the other end, atrophic and hypertrophic gastritis were positioned. The most frequent associations pointed out endoscopically are those with 1st degree esophagitis - 51.6%, duodenitis – 45.07% and purpuric duodenitis – 24.74%.Conclusions. The H. pylori infection is the most frequent etiologic factor for chronic gastritis (54.94%). The early identification of the infection is essential to destroy the bacteria and to prevent the development of various types of gastritis that are later on endoscopically identified.

МОДЕЛЬ МИГРАЦИИ НАСЕЛЕНИЯ В АГЛОМЕРАЦИЯХ В РАМКАХ ПАРАДИГМЫ «УМНОГО ГОРОДА»
Authors: Казанцева Е.Ю. , Даненова Г.Т.
Published: July 2021

Городская агломерация представляет собой множество поселений, которые объединены согласно хозяйственным, трудовым, культурно-бытовым и рекреационным характеристикам. Агломерация воспринимается как целостное территориальное объединение, поэтому очень важно рассматривать именно его в рамках парадигмы «умного города». Все передвижения населения внутри агломерации, несмотря на кажущуюся хаотичность, можно представить систематически и выделить определенные закономерности. Эти закономерности позволят оптимизировать инфраструктуру города, сформировав его транспортную систему таким образом, что станет возможным исключить потенциально аварийные участки на дорогах и снизить транспортную нагрузку на магистрали. С целью оптимизации инфраструктуры агломерации рассматривается существующая модель транспортных сетей и перемещение населения (миграция) внутри нее. В статье представлен анализ парадигмы «умного города», описана ее многомерная структура и уровни, на которых строится городская инфраструктура, и приведены математические модели, на основе которых формируется транспортная система агломерации. Для описания модели перемещения населения в рамках агломерации рассматривается хранилище данных, в котором содержится информация о городской транспортной сети, содержащей набор пунктов и проложенных между ними коммуникаций. На основе данной транспортной сети формируется маршрутная сеть, которая представляет собой совокупность всех транспортных маршрутов. В работе приведено описание модели транспортно-распределительной системы с учетом временных и пространственных характеристик и модель интеллектуальной транспортной системы города на основе гиперсети. Описаны модели транспортных систем, применяемые в опыте зарубежных стран, где на данный момент сохраняется тенденция к улучшению систем навигации и мониторинга в рамках транспортной интеллектуальной системы города.

В рамках данной статьи рассматриваются методы и способы автоматизации оптимизации программного обеспечения при помощи их программ. Проанализируем алгоритмы и принцип действия. Так как на фоне быстрого роста вычислительных мощностей возникает вопрос о рациональном использовании данных ресурсов. С развитием технологий разработка ПО встречается с проблемой деградации качества создаваемых приложений и отсутствия поиска новых методов оптимизации. Первоначально разработка программного обеспечения столкнулась с непреодолимой стеной в виде жестокого лимита ресурсов, что стимулировало разработчиков искать новые методы и ухищрения для реализации задуманного проекта. В данный момент, из-за колоссально быстрых темпов развития вычислительных мощностей, разработчики потеряли данную стену как стимул в поисках новых методов реализации и оптимизации. Разработчики столкнулись с новой проблемой – рациональное использование вычислительных мощностей. Для многих приложений следующего поколения ограничения, налагаемые вводом-выводом, ограничивают уровень достижимой производительности. Большой и важный класс ресурсоемких приложений является нерегулярным, содержит сложное, зависящее от данных поведение выполнения, и динамический, с меняющимися потребностями в ресурсах, которые со временем меняются. Поскольку взаимодействия между приложением и системным программным обеспечением меняются между приложениями и во время выполнения одного приложения, аналитикам, стремящимся оптимизировать производительность, требуются библиотеки времени выполнения и инструменты анализа, которые могут выявить поведение ввода-вывода приложения. Для достижения поставленной цели можно использовать как ручные методы оптимизации, так и оптимизирующее стороннее ПО или оптимизирующие компиляторы. Оптимизирующее стороннее ПО и компиляторы помогут сократить время, затрачиваемое на этап оптимизации.
PROTEIN IDENTIFICATION USING SEQUENCE DATABASES
Authors: Golenko Ye , Ismailova A , Rais Ye
Published: July 2021

The bottom-up proteomics approach (also known as the shotgun approach), based on the digestion of proteins in peptides and their sequencing using tandem mass spectrometry (MS/MS), has become widespread. The identification of peptides from the obtained MS/MS data is most often done using available sequence databases. In this paper, we present a detailed overview of the peptide identification workflow and description of the main protein bioinformatics databases. Choosing the correct search parameters and the sequence database is essential to the success of this method, and we pay special attention to the practical aspects of searching for efficient analysis of MS/MS spectra. We also consider possible reasons why database search tools cannot find the correct sequence for some MS/MS spectra, and highlight the issues of misidentification that can significantly reduce the value of published data. To help assess the assignment of peptides to MS/MS spectra, we will look at the scoring algorithms that are used in the most popular database search tools. We also analyze statistical methods and computational tools for validating peptide compliance with MS/MS data. The final part describes the process of determining the identity of protein samples from a list of peptide identifications and discusses the limitations of bottom-up proteomics

The article formulates the aims of HEI's activities, as well as approaches to managing all actions that ensure the achievement of the stated aims. The process approach is defined as the main one in the university management system. It is shown that the main directions of improving the activities of the university are the transition to the application of the process approach to the management of HEI and its informatization. On this basis, it is necessary to develop new, more modern university management systems that meet the contemporary requirements for the governance of multifunctional facilities and implement them in the form of process systems. We propose a conceptual model of the implementation of the functions to plan the educational process. The effects on planning functions are presented and the interrelation of these functions in the traditional form of planning is described. The tasks are formulated that need to be solved for modeling and optimizing business processes of planning and monitoring the academic workload to create an effective information technology for automating the functions of information processing. We propose a structural model for the implementation of information and procedural components of IT for planning and monitoring the educational environment. The implementation of this model in software provides the calculation of the optimal planned workload of students and teachers, considering the conditions in which the educational process is implemented.

Published: July 2021

The article describes development of an information system for storing the results of scientific work of the Taraz Regional University named after M. H. Dulaty. Today, such works are organized in a non-automated way. In addition, this leads to a number of anomalies, namely: errors in data entry, their duplication, complexity of preparing reports, difficulties in finding the necessary information because of the lack of the information system. In order to solve such problems and to improve data quality it is necessary to create research analytical information system that allow to reduce manual workload and use simple and convenient access system to stored information using various queries. The aspects of creating a research information system described in the article can be implemented in any higher educational institution of the Republic of Kazakhstan. In order to create an information system, a functional model was created using the Fusion Process Modeler 4.0 CASE-system. After the decomposition of the diagram, five functions were identified: "Accounting the research staff", "Research", "Accounting the publications", "Dissertation defense", "Reporting". Modern tools are used in the development of a system for analyzing and monitoring the research activities of TarRU: PHP scripting language, which is widely used for web applications, JavaScript, which is well known as a scripting language for interactivity on web pages in browsers, Microsoft SQL Server relational database management system.

Authors: Serbin V. , Zhenisserov U.
Published: July 2021

Since the stock market is one of the most important areas for investors, stock market price trend prediction is still a hot subject for researchers in both financial and technical fields. Lately, a lot of work has been analyzed and done in the field of machine learning algorithms for analyzing price patterns and predicting stock prices and index changes. Currently, machine-learning methods are receiving a lot of attention for predicting prices in financial markets. The main goal of current research is to improve and develop a system for predicting future prices in financial markets with higher accuracy using machine-learning methods. Precise predicting stock market returns is a very difficult task due to the volatile and non-linear nature of financial stock markets. With the advent of artificial intelligence and machine learning, forecasting methods have become more effective at predicting stock prices. In this article, we looked at the machine learning techniques that have been used to trade stocks to predict price changes before an actual rise or fall in the stock price occurs. In particular, the article discusses in detail the use of support vector machines, linear regression, and prediction using decision stumps, classification using the nearest neighbor algorithm, and the advantages and disadvantages of each method. The paper introduces parameters and variables that can be used to recognize stock price patterns that might be useful in future stock forecasting, and how the boost can be combined with other learning algorithms to improve the accuracy of such forecasting systems.

On the Impulsive Heating of Quiet Solar Corona
Authors: Upendran Vishal , Tripathi Durgesh
Published: July 2021

The solar corona consists of a million degree Kelvin plasma. A complete understanding of this phenomenon demands the study of quiet Sun (QS) regions. In this work, we study QS regions in the 171 Å, 193 Å, and 211 Å passbands of the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory, by combining the empirical impulsive heating forward model of Pauluhn & Solanki with a machine-learning inversion model that allows uncertainty quantification. We find that there are ≈2–3 impulsive events per minute, with a lifetime of about 10–20 minutes. Moreover, for all the three passbands, the distribution of power-law slopeαpeaks above 2. Our exploration of correlations among the frequency of impulsive events and their timescales and peak energy suggests that conduction losses dominate over radiative cooling losses. All these findings suggest that impulsive heating is a viable heating mechanism in QS corona.
Boundary Conditions at the Heliospheric Termination Shock with Pickup Ions
Authors: Gedalin Michael , Pogorelov Nikolai V. , Roytershteyn Vadim
Published: July 2021

In a collisionless shock the directed flow energy is converted mainly in thermal energy of the plasma species. At the termination shock (TS) a substantial portion of energy goes into heating of pickup ions (PUIs), while heating of the solar wind protons (SW) is weaker than it would be without PUI. Heating of both species is nonadiabatic. Downstream pressure of the mixture is determined by conservation laws for the whole mixture. SW heating is sensitive to the details of the shock front, while heating of PUI is not. The profile is an analytical approximation of the observed TS. Here the downstream temperature and pressure of PUIs are obtained for the first time using test particle analysis in a model shock profile for various magnetic compression ratios and shock angles. The profile is an analytical approximation of the observed TS. The results of the analysis are used in the pressure balance equation and the corresponding SW heating is estimated. The analysis is supported by full particle simulations, except for the SW heating that was not studied using test particle data due to its apparent dependence on fine structure of the shock front.

Published: July 2021

Gravitational wave (GW) events, produced by the coalescence of binary neutron stars (BNSs), can be treated as the standard sirens to probe the expansion history of the universe, if their redshifts can be determined from electromagnetic (EM) observations. For the high-redshift (z ≳ 0.1) events, the short γ-ray bursts (sGRBs) and the afterglows are always considered as the primary EM counterparts. In this paper, by investigating various models of sGRBs and afterglows, we discuss the rates and distributions of the multimessenger observations of BNS mergers using GW detectors in the second-generation (2G), 2.5G, and 3G era with detectable sGRBs and afterglows. For instance, for the Cosmic Explorer GW detector, the rate is about 300–3500 yr−1 with a GECAM-like detector for γ-ray emissions and an LSST/WFST detector for optical afterglows. In addition, we find that these events have redshifts z ≲ 2 and inclination angles ι ≲ 20°. These results justify the rough estimation in previous works.

We measured high-quality surface brightness fluctuation (SBF) distances for a sample of 63 massive early-type galaxies using the WFC3/IR camera on the Hubble Space Telescope. The median uncertainty on the SBF distance measurements is 0.085 mag, or 3.9% in distance. Achieving this precision at distances of 50–100 Mpc required significant improvements to the SBF calibration and data analysis procedures for WFC3/IR data. Forty-two of the galaxies are from the MASSIVE Galaxy Survey, a complete sample of massive galaxies within ∼100 Mpc; the SBF distances for these will be used to improve the estimates of the stellar and central supermassive black hole masses in these galaxies. Twenty-four of the galaxies are Type Ia supernova hosts, useful for calibrating SN Ia distances for early-type galaxies and exploring possible systematic trends in the peak luminosities. Our results demonstrate that the SBF method is a powerful and versatile technique for measuring distances to galaxies with evolved stellar populations out to 100 Mpc and constraining the local value of the Hubble constant.

Triton is an important signpost in understanding the diverse populations of both ocean worlds and Kuiper Belt objects (KBOs). As a likely ocean world, it is unique by virtue of its kidnapped history from the Kuiper Belt: its large orbital inclination makes it the only ocean world thought to be primarily heated by obliquity tides. It is volatile-rich due to its formation in the outer solar system and its unusual surface geology may be the product of cryovolcanism. Observations from New Horizons and Cassini motivate re-examination of Triton data sets and models, with value for comparative planetology of ocean worlds and KBOs, most notably with Europa, Enceladus, Titan, and Pluto. We re-explore old data sets with the new perspective of the importance of ocean worlds in our solar system and the search for life.

Global Nursing Education: International Resources Meet the NLN Core Competencies for Nurse Educators
Authors: Keating Stacen , Berland Alex , Capone Kathleen , Chickering Miriam
Published: July 2021

The global need for nurses and nurse educators presents a challenge to meet the needs of the world-wide population. International level targets, such as the United Nations Sustainable Development Goals, are in place and expectations of graduates are evolving rapidly due to increasingly complex healthcare needs. The capacity of effective nurse educators is a significant constraint to addressing the global shortage of nurses. The National League for Nursing (NLN) has established eight core competencies for nurse educators to ensure that education of nurses is robust. This article briefly discusses the shortage at hand. We describe the Nurses International - Open Educational Resources (NI-OERs) initiative to align freely available content and support with the NLN competencies to develop nurse faculty and attain nursing education equity in low and middle-income countries. In conclusion, this work will help to develop a better prepared cadre of global nurse educators who can equip nurses with current evidenced based knowledge to deliver healthcare across global populations.

Published: July 2021

El conocimiento nunca es evidente por sí mismo y es siempre una lucha por la evidencia: lo que cuenta y lo que no cuenta. El conocimiento es parte de la política de la evidencia. Necesitamos desentrañar los procesos que crean valores de verdad en un campo de poder. Aquí deseo abordar la tensión entre la experiencia, el conocimiento vernáculo y la evidencia, ya que constituyen los cimientos de la movilización política durante la recesión económica en España. ¿Cómo se valora la experiencia y qué tipo de conocimiento sobre la sociedad produce? ¿Cómo podemos involucrarnos con este conocimiento como antropólogos/as que intentan comprender qué son los hechos sociales y el valor que tienen como evidencia en la discusión y la lucha políticas?
Tachar y borrar: Tácticas para cambiar el pasado
Authors: Ingold Tim
Published: July 2021

Al editar un texto a mano, las líneas pueden tacharse, o eliminarse, en actos de borrado. Este artículo sostiene que el tachado y la supresión son opuestos, tanto operacionalmente como en sus efectos superficiales. Mientras que el tachado raya físicamente las palabras, ontológicamente no hace más contacto con la superficie sobre la que están escritas que una línea inscrita en un espejo con lo que se refleja en el vidrio. Es como si el trazo se dibujara a través de otro plano, superpuesto a la página de escritura. Sin embargo, frotar o rayar erosiona la superficie misma. Cuando la misma superficie se reutiliza repetidamente, como era común con la escritura en pergamino, surgen huellas del pasado mientras que las huellas del presente se hunden. Lo mismo ocurre con la reutilización del suelo, en ciclos de cultivo. Ambos conducen a la formación de un palimpsesto. Con el palimpsesto, darse la vuelta es fundamental para la renovación. El estado territorial, por el contrario, asume que el suelo está estratificado en capas, apilado en una secuencia temporal. La renovación, entonces, solo puede llegar agregando más capas. Llegamos así a una distinción entre dos tipos de superficie: la superficie estratificada, que cubre lo anterior y se cierra a lo que sigue; y la superficie profunda, que no cubre nada más que a sí misma y, sin embargo, se eleva al aire libre. Estas superficies encarnan, respectivamente, los principios contrarios de estratigrafía y antiestratigrafía. El camuflaje funciona engañándonos para que tomemos un tipo de superficie por otra. El ejemplo del entierro, sin embargo, muestra cómo ambos principios pueden combinarse. Enterrar el pasado lo pone a un lado, pero no lo hará desaparecer. Solo cuando finalmente salga a la superficie, el pasado podrá ser borrado por los estragos del tiempo.
Escuchar a los objetos

Published: July 2021

Esta sección experimental incluye algunas partes del evento performativo “La materialidad de las transformaciones: escuchar a los objetos”, que clausuró el XIV congreso de SIEF celebrado en Santiago de Compostela en 2019. Barbara Kirshenblatt-Gimblett, Regina Bendix, Dorothy Noyes, Sharon Roseman y Francisco Cruces conversaron sobre los significados culturales de una selección de objetos personales. Al desvelar las historias contenidas en mezuzahs, cabello, una fuente o un chal, se puso a prueba el poder metodológico del par objeto / historia, los beneficios de articular la narratividad con la materialidad y el silencioso poder de las cosas en la vida cotidiana. Se destacó el carácter incorporado de la narración y algunas de sus virtudes afectivas, morales y celebratorias. Este evento performativo se puede ver en  from minute 00:52:50 to 01:31:00.
Movilidad, sujeto y práctica social. Observaciones en una estación de autobuses
Authors: Anta Félez José Luis
Published: July 2021

A través de la estación de autobuses de la ciudad de Jaén, se desgrana la genealogía reciente de esta ciudad: su territorio, su conformación histórica y aparataje simbólico. Como parte de los edificios creados por el desarrollismo franquista, con los cambios recientes hacía la idea de patrimonio histórico, se realiza un acercamiento, también, a su dinámica interna, como un teatro de constantes interacciones simbólicas. Por último, se centra todo el trabajo en entender, a través de este espacio estratégico y privilegiado para la micro investigación social, el concepto de movilidad, la idea de transporte, de interconectividad y todas las posibles gestiones físicas y subjetividades con las que trabaja el Estado, la empresas poscapitalistas y sus formas híbridas, y que tienen como resultado un constante orden normativo, disciplinamiento, vigilancia, mercantilización, control del riesgo y transtradicionalidad, tanto sobre los cuerpos de los sujetos, como en las prácticas que generan.
20 ans de CCO, l’âge de l’action ? À la recherche d’une Utopie
Authors: Fauré Bertrand , Arnaud Nicolas
Published: July 2021

Cet article soulève deux « incapacités » actuelles des recherches en communication organisationnelles : incapacité à anticiper l’essor technologique ; incapacité à réaliser l’utopie organisationnelle portée par les sciences de la communication. En réponse à ces « incapacités », nous proposons des pistes de recherches futures pour contribuer à les dépasser en nous appuyant notamment sur les travaux d’Habermas.
Rendre compte du travail d’instauration et d’assemblage des données en santé : le cas de Registres des cancers en France
Authors: Martin-Scholz Anja , Mayère Anne , Lambotte François
Published: July 2021

La montée en puissance des discours promouvant le « Big Data » laisse à penser qu’il suffirait d’accumuler et de croiser un nombre suffisant de « données » pour avoir une vue exhaustive des phénomènes. En prenant appui sur une recherche en cours sur le terrain d’organisations en charge de la production de Registres des cancers, nous proposons de spécifier le processus d’instauration des données en articulation avec leurs assemblages. Il s’agit ainsi de caractériser ce qui fonde les modes d’existence des données et de leurs assemblages hétérogènes et instables. Dépassant la focale sur les finalités affichées, il s’agit de mieux comprendre ce qui est à l’œuvre dans la fabrique des données, à travers des zooms avant et arrière. Sont ainsi identifiés des enjeux en termes de savoir mais aussi en termes politiques, économiques et sociaux.
Technologies innovantes et communication d’acceptabilité
Authors: Saglietto Laurence , Charest Francine
Published: July 2021

Aujourd’hui, la distanciation sociale, imposée par les crises sanitaires, nécessite de repenser les stratégies appliquées de communication-marketing des centres commerciaux. L’utilisation à bon escient de certaines technologies innovantes qui permettent de gagner en distanciation sociale s’avèrent un début de solution à condition qu’elles soient soutenues par des principes de communication d’acceptabilité. Cette réflexion théorique s’interroge sur les pratiques de communication d’acceptabilité sociale à mettre en place à l’égard de ces technologies innovantes pour in fine gagner en distanciation sociale.
La triple mimésis de Ricœur comme herméneutique des événements de communication constitutifs de l’organisation
Authors: Christophe Christel , Jojczyk Joanne , Lambotte François
Published: July 2021

Partant du constat que beaucoup de recherches en CCO peinent à expliciter la démarche de sélection des événements constitutifs de l’organisation étudiée, nous proposons une démarche méthodologique fondée sur une approche narrative inspirée du travail sur les mimesis de Paul Ricœur. Le récit y est étudié pour sa capacité herméneutique et plus particulièrement pour sa capacité à outiller le chercheur dans le cadre de la sélection des événements de communication à analyser. Notre contribution à la CCO est d’ordre méthodologique et dessine les contours d’une approche qui permet, selon nous, d’expliciter une étape préliminaire nécessaire à l’analyse : la sélection des données en amont de leur catégorisation en « événements constitutifs ».
Le devenir révolutionnaire de l’approche constitutive de la communication
Authors: Del Fa Sophie
Published: July 2021

Cet article sous forme d’essai engage une réflexion sur le devenir révolutionnaire des approches constitutives de la communication (CCO), et ce pour la concevoir comme une théorie utile et nécessaire pour changer radicalement notre rapport au monde. L’article est construit autour de trois propositions théoriques et sur la conception politique de la communication de Hardt et Negri, point d’appui central. Il va sans dire que cette réflexion est motivée par la volonté d’engager la CCO dans une discussion relevant d’une critique radicale de la société soumise au capitalisme néolibéral, régime de biopouvoir qui contrôle tous les aspects de la vie sociale. Cet article repose sur la conviction fondamentale que la théorie en sciences humaines et sociales doit être au service de la résistance aux pratiques de domination aliénantes dans une perspective émancipatrice.
Beyond the Pandemic
Authors: Irvin David Robert
Published: July 2021

This chapter argues that libraries should sustain and increase allocations to cloud computing technologies following the COVID-19 pandemic, rather than falling back into old management styles. The power of the collaborative environment makes it possible to administratively restructure the library to improve efficiency in the virtual domain, where libraries will find themselves operating more and more. Remote work arrangements have altered the relationship between employee and employer, setting new expectations and demanding new ideas about operations. The author discusses how this “new normal” will necessitate changes in how directors govern their staff, especially in an era of reduced budgets.

This study aims to comprehensively discuss the ways East West University Library (EWUL), Bangladesh transformed its role during COVID-19 pandemic situation as well as delineate the challenges faced in this quest. This study is basically exploratory in nature. A systematic literature review and document analysis has been conducted, and the author's viewpoints and experiences have also been incorporated in this chapter.
Using Social Media for Dynamic Information Dissemination in the 21st Century
Authors: Ajegbomogun Fredrick Olatunji
Published: July 2021

The implementation and usage of information and communication technology (ICT) in library functions and facilities has revolutionized the way people use information and librarians perform their work. As a result of the advent of social media, the world's knowledge outlook has changed significantly, resulting in the sharing of thoughts, emotions, images, and videos as resources. A library is worth considering; it is a key to learning, a foundation for long-term mastery of information, and it promotes independent decision-making. The use of social media in library activities has enticed a significant number of users, but it has also challenged libraries to modernize their service delivery. Facebook, Twitter, Wikis, WhatsApp, MySpace, and LinkedIn facilitate community courses, collaboration, and information sharing. As a consequence, it is vital for libraries to consider and prioritize their users' needs.
Innovations and Use of Assistive Technologies in Libraries of Institutions of Higher Learning
Authors: Chigwada Josiline Phiri , Phiri Josephine Dinar
Published: July 2021

Access to information for all is a major component of library and information science in this digital era. Libraries in institutions of higher learning are mandated to provide information to all the patrons regardless of their ability to deal with the issue of inclusivity and social justice. A study on the innovations was conducted specifically for patrons with special needs in academic libraries. Different assistive technological types of equipment were outlined as well as the challenges encountered when using the assistive technology tools and applications. The observation was done at one of the academic libraries, and it was discovered that the library has a disability center that is used by patrons with special needs and manned by a trained librarian. The authors recommend the introduction of such services in all the academic libraries to cater to patrons with special needs.

Authors: Kaur Navkiran , Kaur Satinderbir
Published: July 2021

Good health is essential for every human being. Health information is essential for maintaining good health, preventing diseases as well as making sound health decisions. People can only be able to access, utilize, and benefit from healthcare services if they have proper information about these services. It is here that health information literacy comes into play. The information related to every aspect of health is easily available today, but the main problem here lies in finding, selecting, and using relevant health information and preventing misinformation. Libraries have a pivotal role to play here. This chapter is mainly concerned with identifying the gaps in the provision of health information to the general public and the role of health information literacy in paving the way of filling up these gaps. It will be helpful in knowing the current standing of public and medical libraries in providing health information resources and services. It will also suggest the role of these libraries of India in promoting health information literacy among their respective user communities.

Published: July 2021

The economy has taken a new facet in recent times through technologies like Information and Communication Technologies (ICT), ushering radical change in all sectors in developed and developing nations. ICT has transfigured the traditional services and productivity of libraries and other organizations to more sophisticated methods. A powerful catalyst of this change is digital transformation, integrating ICTs into the economy, referred to as the “digital” economy. However, the chapter identified ingredients of the digital economy, and spheres ICT have influenced the digital economy. Information and Communication Technology Council (ICTC) and Spires and Barlett frameworks were adopted to buttress digital skill sets required for functioning effectively in the digital economy. Additionally, the chapter examines the promising future of ICT and the importance of entrepreneurship. Challenges were identified to affect full ICT implementation by developing countries in the digital economy. The chapter concluded that ICT is a key determinant and contributor to economic development in many nations.
