ABSTRACT

The hearing impaired Persons constitute a very small percentage of the total population. The article presents the information regarding the infrastructure, the library services to the special group of library users. All the public/academic libraries do not provide services to these groups of the users, hence the institutions specially meant for these persons are responsible for administering services to this group of users. Assistive technology can help to a great extent in providing library services to these groups of users.

Essentially, the article describes several technologies and their applications in library operations. The study has discussed how library services are spurred by the use of technology such as OPAC, E-ShodhSindhu, E- books and E-journals, and so on. The current study examines several library activities that make use of ICTs. The goal of this paper is to demonstrate the use of various ICTs and E-resources by user of the university for rapid and easy information retrieval.

ABSTRACT

It is very important for every library to have all the resources/materials necessary to fulfil its target. The working of a library can be classified into two forms: dealing with the users and behind the scene. There are numerous different sections in a library divided on the basis of their functions. Most important of these is the Acquisition section. A library’s success lies in a well organized acquisition section. Main aim of the library is the contentment of the users. However, collection development is the primary task of the acquisition section which further contributes to user satisfaction itself. It performs the process of selection, procurement and accessioning of reading materials as well as maintains records. It organizes the monetary as well as human resources in such a manner that collection is facilitated more and that too in an economic and less time consuming way. All this is the responsibility of the librarian. Before acquiring the reading materials, the librarian is supposed to decide that which items are actually required in the library and which are to be rejected. A librarian must study the requirements of the library and acquire materials as per the priorities of the institution to achieve its goal.

ABSTRACT

Ethical conduct of research is utmost important which form the basis of overall development of society. Academic institutions can play key role in promoting scientific integrity by creating awareness about scientific misconduct and can frame policies to curb scientific misconduct. As a part of course curriculum knowledge about various issues related to academic integrity can be easily passed to young researchers and students of the institution. Awareness programs can play significant role in promoting research integrity for which academic libraries can be the frontrunner. Librarians’ role is also changing as they have not limited themselves to traditional services but are also providing web based services to the users. They can support research community by providing services like reference management through the use of reference management tools and data management and preservation services. Faculty development programs are also helping the working librarians to update their knowledge. This article discuss about the concept of academic integrity and role of academic institution in promoting it in general and library in particular. PA U library faculty has taken a lead in raising the awareness of students and researchers about research and publication ethics by teaching this course to as part of the course curriculum to research scholars and post graduate students of the university. It is also facilitating teaching community and researchers in plagiarism checking of the manuscripts through the use of antiplagiarism software.

ABSTRACT

The advent and implementation of Information and Communication Technology (ICT) in library operations changed the overall information scenario. The format of libraries, information resources and user expectations are completely changing. Similarly, the role of librarian is continuously changing in the digital era. No library can fulfill the informational demands of the users; hence, resource sharing is required between the libraries. Consortiums are developed to enable the institutions to access the rich and scholarly resources at an affordable cost. The present paper discusses the basic concept of resource sharing, consortium types, need, advantages and disadvantages and its role in sharing information.

Keywords: ICT, Consortium, Library consortia, Resource sharing.

ABSTRACT

There is a tremendous growth in the open educational resources in the recent past and large number of universities and academic organisations are making their resources freely available over the internet which has become a significant source of open educational content. Open education movement are built on the belief that anyone can use, access, reuse and redistribute these educational resources without any constraints. These Open education movements are helping educational community worldwide in making education more accessible and in making it more effective. In this chapter effort has been made to provide an overview of the history and emergence of open educational resources’ movement. This chapter also explains the various characteristics and sources of open educational resources. This chapter will help the libraries and librarians to know about open educational resources initiatives and to incorporate them in their libraries for effective resource delivery and disseminations.

ABSTRACT

As we all know that emergence of internet has completely changed the way of transferring knowledge. Online videos and lectures have been adopted by the online educational community to meddle into the MOOCs massively to disperse the knowledge. No field has remained untouched from MOOCs. This is basically a study on the available MOOCs in India in Library and Information science.

Keywords: MOOCs, Massive Open Online Course, SWAYAM, Library and Information Science.

1. Introduction

Dave Cormier devised the term Massive Open Online Course (MOOC) in 2008 to describe an open online course “Connectivism and Connective Knowledge” designed by Siemens and Downes. University of Manitoba offered MOOC for the first time in 2008 formally as a credit course to regular students and informally with enrolment open to anybody in the world free of cost. Since then, there is proliferation of MOOCs worldwide.

ABSTRACT

Academic libraries are unique, essential and strategic hubs inside our social cloth which are advanced primarily based totally at the requirements of the times, to help people in the purchase of good enough facts that could allow them to decorate their information, for the development in their wellness and that of the society at large. To attain their goal, they ought to generate, filter, control and diffuse correct and well timed human information which have been harvested and documented; for the purpose of enriching the highbrow needs in their clients. Like every other kind of library, academic libraries are growing organisms. Justification to the above statement has been captured aptly in the classic book of Ranganathan (1931) entitled ‘Five Laws of Library Science’; detailing the principles of the library profession. The philosophical postulation of Ranganathan’s fifth law is a classical position that offers much strength and support for the need to adequately plan for the best strategies to exhibit in academic library environments in order to provide effective services. In other words, the fore-stated law by Ranganathan has already signaled that academic librarians must be ready at all times to effectively satisfy the diverse, complex and ever-increasing information needs of their users from the explosive available information resources that spring on a daily basis. As such, addressing this issue would require a holistic management approach by academic libraries that must be internally efficient and externally effective.

ABSTRACT

The chapter focuses that information as an economic resources and the role of library to distributing information among the user’s communities. From the economic point of view-the most important properties of information are easy to access and limited money acquire more information i.e. cost benefit. Information economy makes people ware about their goal and library help people to provide resources on need base.

ABSTRACT

With the advancement of mobile technology, the usage of mobile application has increased significantly which leads to change the life style of common people. Library is also not an exception in this context. Library and Information Science Professionals have started to incorporate the changes from the beginning of ICT advancement with an idea “library should be within thumb of people”. Mobile application plays vital role to fulfil the objective of library. Most of the library has started or planning to start the service to its user with various services effectively. But, the process to provide library service through mobile application is not satisfactory till date. No too much usage of libraries mobile apps can be seen; even which mobile applications are in use, most of them are almost inactive form.

But the various recent surveys show us the tremendous growth of the usage of mobile application among people. According to Google, (2017) the user survey shows that mobile can fast-track time to purchase by 20% through facilitating efficiencies in decision-making and enhanced team collaboration, particularly with more complex purchases.

ABSTRACT

World is suffering from coronavirus infection since the end of 2019. Corona virus disease spraying rapidly throughout the world from the beginning of 2020, for that cause it is declared as pandemic by WHO in march 2020. As no proper remedy found for this particular new disease till the date it is become oblivious to maintain social distancing and lock down. Due to the situation each and every sector including the education system totally stopped from March 2020. But we have to maintain the flow of education. Many of the educational institution of India promoted e learning for their students. To avoid coronavirus infection social contact as well as to carry out classes in regular manner, it is become necessary to promote e learning everywhere. But in India the situation is different because Steel we are a poor country where a good number of people do not have a smart phone even. There are many challenges in promotion of e-Learning during this coronavirus pandemic situation in India. In present paper we are going to discuss about some challenges in promotion of e-learning due to coronavirus pandemic situation.

ABSTRACT

With the rapid innovation in Information and Communication Technologies (ICTs), the libraries and information centres have gone through tremendous changes or facing transformation. In this digital era, libraries are facing heavy technological pressure to serve their users on their satisfaction level. Library and information professionals are also struggling more to implement these cutting-edge technologies for learning, research, and information for their users. Therefore, the library and information centres have now been trying to adopt and implementing various emerging or cutting-edge technologies in housekeeping activities as well as in its services. In this paper, an effort has been made to evaluate some of the cutting-edge technologies in libraries’ point of view. An overview is also made to evaluate the concept, advantages and disadvantages of cutting-edge technologies.

10.1 Introduction

The consistent process of rapid urbanization and expeditious developmental activities have severely impacted the environmental components and thereby the quality of life. With limited natural resources, individuals and societies have to learn to bring in attitudinal changes in order to accomplish environment sustainability (UNESCO). From the Book “Our Common Future” (Brundtland Report), the concept of Sustainable Development can be understood as the “development that meets the needs of the present, but does not threaten the ability of future generations to meet their own needs”. 

Introduction

With ever-increasing population growth, waste management has become a major challenge threatening environmental sustainability. The total solid waste generation was recorded to be 1.3 billion tonnes per year by the world’s cities in 2012, with an ecological footprint of 1.2 kilograms per person/day. With the intensity with which the population growth is happening coupled with urbanization, predictions are made that by the end of the year 2025, 2.2 billion tonnes of municipal waste will be generated (The World Bank, 2018). 

8. Introduction

The idea of sustainable development stands on the concept of maintaining the best possible environment within the availability of minimal resources and for the convenience of the society. Now-a-day the term “sustainability” gained a lot of attention due to challenges and problems faced in tackling the current situation of global pollution. One of the vital areas of research needs to be addressed in concern with sustainable development is the new innovations to enhance sustainability (Silvestre and Silva, 2014). 

7.1. Developing Sector in Scientific and Technological Approach of Waste Management

From the very past, many traditional practices have been put into use for waste management like landfilling, composting, and recycling, which are practiced even today. However, the boundless upsurging waste compels the modern world to modify the traditional methods or to introduce innovative techniques with the grace of technology

6.1 Introduction

Urbanization is now a global phenomenon, but in developing countries the implications are more pronounced. Natural growth of population, reclassifications of habitation and migration trends are important in urban population in India. The population of India, which accounts for 27 per cent of the total population, was 285 million according to 2001 census. International experience shows that the pace of urban development accelerates when a country’s urban population crosses close to 25 percent of the total population (like in India).(Kumar and Chakrabarti, 2010). 

Definitions: Before starting the chapter, it is better to understand the basic definitions of the terms commonly used in this chapter.

Waste: Waste is any material or object which is discarded after its primary use by its holder. A holder means the person who produces and keeps the waste. 

4.1. Introduction

Presently, in the world, there are 195 countries according to the United Nations, and the number would even go up to 247 if we consider the disputed territories like Isle of Man, Hong Kong, etc. (United Nations, 2016) (Kershner, 2020). But the majority of the countries are still struggling to provide basic life-supporting amenities like nutrition, shelter, and employment. Conjointly, termed as emerging and developing countries such as India, Vietnam, Venezuela, Utopia, etc. (Ahmed and Shimada, 2019). Most of the developing countries are situated mainly in the continent of Africa, Asia and South America. They have got independence for the European countries like England, France, Portugal and Spain in the mid and late 20th century. 

3.1 Introduction

A Massive increase in population, urbanization and industrialization have led to an increase in the quantity and composition of waste. The waste is increasing day by day and is estimated to reach up to 2.2 billion tonnes by 2025, according to the reports by World Bank. It becomes a necessity for every nation to fore look upon the waste management system for their respective countries. From the collection, segregation, transportation, disposal all have become an important criterion to deal with. Among the available disposal options; the easiest and environment friendly is “Recycling”. 

1.1 Introduction

Increased emission of greenhouse gases results in climate change which becomes one of the most prominent environmental issues to the world today. Carbon dioxide (CO2) is the major greenhouse gas whereas nitrous oxide (N2O) and methane (CH4) are other substantial contributors to climate change (IPCC, 2014, Tongwane et al., 2016). However, these gases are emitted in minimal quantities in comparison to carbon dioxide but impart more global warming effect by absorbing more infrared radiations (Oertel et al., 2016). The warming potential of one kg of CH4 is 23 times more than one kg of CO2 while  in the case of N2O, it was nearly 300 times more than CO2 (Ramaswamy et al., 2001, Bharti et al., 2019; Biswas et al., 2010). Around one-third of methane and two –thirds of nitrous oxide come from soil (Prather et al., 1995, Tubiello et al., 2015, Smith, 2016).

1.1. Background Introduction

We live in a world with “throw-away” societies that are involved in a pattern of consuming packaged products that don’t even last past a single use or even a year and discarding the waste. This lifestyle generating waste is negatively impacting public health, environment and imposing socio-economic problems on us. The waste is continuously consuming our land, resources, and energy for storage, management, treatment, and disposal. Solid waste was an urban issue initially but has reached every corner nowadays. 

18.1 Introduction

The commercially available water quality simulation models with various dimensions (1D, 2D and 3D) and database software designed to quantify movement and concentration of contaminants in lakes, streams, estuaries, and marine environments. The following water quality models were described below (Table 18.1).

18.2 Environmental Fluid Dynamics Code

The Environmental Fluid Dynamics Code (EFDC) is a multifunctional surface water modeling system, which includes hydrodynamic, sediment-contaminant, and eutrophication components. It has been applied to over 100 water bodies including rivers, lakes, reservoirs, wetlands, estuaries, and coastal ocean regions in support of environmental assessment and management and regulatory requirements. IT is a state-of-the-art hydrodynamic model that can be used to simulate aquatic systems in one, two, and three dimensions. It has evolved over the past two decades to become one of the most widely used and technically defensible hydrodynamic models in the world. It uses stretched or sigma vertical coordinates and Cartesian or curvilinear, orthogonal horizontal coordinates to represent the physical characteristics of a waterbody. It solves three-dimensional, vertically hydrostatic, free surface, turbulent averaged equations of motion for a variable-density fluid. Dynamically-coupled transport equations for turbulent kinetic energy, turbulent length scale, salinity and temperature are also solved. The model allows for drying and wetting in shallow areas by a mass conservation scheme.

17.1. Introduction

Throughout human history, the coastal plains and Lowland River valleys have usually been the most populated areas over the world (Wolanski et al., 2004). At present, about 60% of the world’s population live along the estuaries and the coast (Lindeboom, 2002). This is degrading estuarine and coastal waters through pollution, eutrophication, increased turbidity, overfishing and habitat destruction. The pollutant supply does not just include nutrients; it also includes mud from eroded soil, heavy metals, radionuclides, hydrocarbons, and a number of chemicals including new synthetic products.

The impact on estuaries is commonly still ignored when dams and irrigation farming are proposed on rivers. In addition, estuaries are often regarded as sites for future development and expansion, and have been increasingly canalized and dyked for flood protection, and their wetlands infilled for residential areas.

All these factors impact on the biodiversity and productivity and hence, the overall health of estuaries and the ecosystem services they provide to humans. They increasingly lead humans away from the possibility of ecologically sustainable development of the coastal zone. Integrated coastal zone management plans are drawn up worldwide but, in the presence of significant river input, most are bound to fail because they commonly deal only with local, coastal issues, and do not consider the whole river catchment as the fundamental planning unit. It is as if the land, the river, the estuary, and the sea were not part of the same system. When dealing with estuaries and coastal waters, in most countries land-use managers, water-resources managers, and coastal and fisheries managers do not cooperate effectively due to administrative, economic and political constraints, and the absence of a forum where their ideas and approaches are shared and discussed (Wolanski et al., 2004). 

16.1 Introduction

Littoral drift is a geological process by which sediments such as sand or other materials, move along a beach shore.Long Shore Drift is the movement of eroded material, in a zig zag way, along the coast. The process arises when waves approach the shore obliquely. That is to say, at an angle other than 90°. The effect of this is determined by factors such as the direction and fetch of the present wind and, in the long term, of the prevailing wind.

Waves striking the shore at an angle as opposed to straight on will cause the wave swash to move up the beach at an angle. The swash moves the sediment particles up the beach at this angle, while the backwash brings them, solely under the influence of gravity, directly down the beach. Some geologists consider a beach to be merely a shoreline feature of deposited material, but William Bascom (1980) has argued that a beach is the entire system of sand set in motion by waves to a depth of ten meters or more off ocean coasts. Submerged, longshore bars are therefore also part of the beach, and thus beaches can be viewed as either:
