This study aims to examine the impact of information and communication technologies (ICT) usage with mobile technologies and e-learning in academic libraries.
Abstract
Purpose
This study aims to examine the impact of information and communication technologies (ICT) usage with mobile technologies and e-learning in academic libraries.
Design/methodology/approach
Selection of appropriate resources using the Communication and Mass Media, EBSCO, Web of Science and Library Literature and Information Science Fulltext databases.
Findings
The “Library as place” concept requires libraries to explore and re-purpose its physical space while redefining its virtual, online space to align with the needs of those who are native to the digital age. Library information specialists (LIS) must also be knowledgeable of – and comfortable with – the use of the new technologies introduced. As mobile technologies continue to evolve and advance in developing countries, libraries and LIS may be best positioned to assist students and researchers in accessing information required to be proficient and productive in scholarly pursuits without physical boundaries.
Practical implications
The existing research literature surveyed here implies that the growth of ICT and evolving concepts of libraries require the need for LIS training and greater understanding of the use of mobile technologies in providing academic library services.
Originality/value
Academic librarians are at the forefront of providing aspiring academics and professionals with access to digital collections and e-learning courses using mobile information communication and technology devices; the implications of the research discussed in this survey of the current literature discloses a need for diverse skills for the appropriate and continuing effectiveness to support students and academic researchers.

Abstract
Purpose
The purpose of the current article is to explore the rotational behavior on nanofluid flow over an exponentially stretching surface. Heat and mass flux are formulated upon Cattaneo–Christov theory.
Design/methodology/approach
Effect of thermophoretic, Brownian motion and thermally convective conditions is further retained. Novel boundary layer approximations are applied to transform the governing equations of continuity, momentum, energy and nanoparticle volume fraction. Convergent series solutions are obtained to manage the rotating flow with the aid of homotopy analysis method (HAM).
Findings
Depending on the several dimensionless parameters including the local rotation parameter the Prandtl number Pr, the thermophoresis parameter, the Brownian motion parameter, the Lewis number Le, Biot number Bi, Deborah number in terms of heat flux relaxation parameter and Deborah number in terms of mass flux relaxation parameter with the dimensionless physical quantities are deliberated through graphs. Present results are also likened with the foregoing results in significance.
Originality/value
No such assumptions have been made for the development of analytical solution so far.

Abstract
Annotation is a practice that is familiar to many of us, and yet it is a practice so natural that it is hard to pin down its characteristics, to find where its edges are, and identify what it does for us. In this piece, we use reflections on the practices of annotation in four fields of work: academia, software engineering, medical sonography and visual art as a point of departure to theorise annotation as a set of practices that bridge reading, writing and thinking. We think about annotation being performative and consider what and how it brings into being. Revealing hidden practices in our working lives, such as annotation, helps us to understand how knowledge comes to be created, disseminated, legitimated and popularised. To this end, we make the practices of annotation involved in writing the present piece visible in an effort to write differently in management and organisation studies, unpicking and exposing it as ever dialogical and unfinished.

Abstract
Purpose
The purpose of this paper is to address the heat and mass transfer effects in three-dimensional flow of Maxwell fluid over a stretching surface with convective boundary conditions. Mass transfer is considered in the presence of first order chemical reaction. Conservation laws of energy and concentration are based upon the Soret and Dufour effects. Convergent series solutions to the resulting non-linear problems are developed. Effects of Biot and Deborah numbers on the Sherwood number are decreasing. Local Nusselt reduces with an increase in Eckert numbers. It is also interesting to note further that variations of Prandtl and Biot numbers on the Nusselt number are increasing while Sherwood number decreases with an increase in Prandtl number.
Design/methodology/approach
The involved partial differential systems are reduced to the ordinary differential systems using appropriate transformations. Series solutions by homotopy analysis method are constructed and analyzed. Graphical results are presented and examined in detail.
Findings
It is found that roles of Deborah and Biot parameters on the Nusselt number are opposite. However, the Sherwood number is qualitative similar for both Biot and Deborah numbers. It is also interesting to note further that variations of Prandtl and Biot numbers on the Nusselt and Sherwood numbers are similar.
Originality/value
The purpose of present communication is to investigate the three-dimensional flow of Maxwell fluid over a stretching surface with convective condition. Analysis has been carried out in the presence of mass transfer with first order chemical reaction and Soret and Dufour effects.

Abstract
Life studies are a rich source for further research on the role of the Afro‐American woman in society. They are especially useful to gain a better understanding of the Afro‐American experience and to show the joys, sorrows, needs, and ideals of the Afro‐American woman as she struggles from day to day.

Abstract
Purpose
To conduct a systematic review of public relations ethics (PRE) research and scholarship in the 21st century and suggest future research directions. The study is prompted by macro-level phenomena that have impacted societies since the beginning of the 21st century—notably globalisation 4.0 and the fourth industrial revolution.
Design/methodology/approach
A systematic review was used to search academic literature. Articles discussing PRE in nine leading English-language public relations and business ethics journals between 2000 and 2019 were reviewed. A code-frame facilitated data extraction and subsequent quantitative analysis; qualitative analysis identified key themes.
Findings
The review identified 288 articles, with discussions involving PRE increasing over time. Most works approached the topic generally, rather than from a specific sub-disciplinary perspective, and drew from professional settings. Works were dominated by authors from North American institutions and North American samples. Research became increasingly empirical and intra-disciplinary and discussion about ethics was broadly categorised as part of public relations practice or from the perspective of the “academy”. Overall, the field can be described as of notable size, maturing, yet unbalanced in some regards.
Originality/value
The review helps to identify whether PRE research reflects major changes in the 21st century and augments the sparse recent reviews of PRE research.

Abstract
Purpose
This investigation has been carried out for thermal-diffusion (Dufour) and diffusion-thermo (Soret) effects on the boundary layer flow of Jeffrey fluid in the region of stagnation-point towards a stretching sheet. Heat transfer occurring during the melting process due to a stretching sheet is considered. The paper aims to discuss these issues.
Design/methodology/approach
The authors convert governing partial differential equations into ordinary differential equations by using suitable transformations. Analytic solutions of velocity and temperature are found by using homotopy analysis method (HAM). Further graphs are displayed to study the salient features of embedding parameters. Expressions of skin friction coefficient, local Nusselt number and local Sherwood number have also been derived and examined.
Findings
It is found that velocity and the boundary layer thickness are increasing functions of viscoelastic parameter (Deborah number). An increase in the melting process enhances the fluid velocity. An opposite effect of melting heat process is noticed on velocity and skin friction.
Practical implications
The boundary layer flow in non-Newtonian fluids is very important in many applications including polymer and food processing, transpiration cooling, drag reduction, thermal oil recovery and ice and magma flows. Further, the thermal diffusion effect is employed for isotope separation and in mixtures between gases with very light and medium molecular weight.
Originality/value
Very scarce literature is available on thermal-diffusion (Dufour) and diffusion-thermo (Soret) effects on the boundary layer flow of Jeffrey fluid in the region of stagnation-point towards a stretching sheet with melting heat transfer. Series solution is developed using HAM. Further, the authors compare the present results with the existing in literature and found excellent agreement.

Abstract
Pain is socially and culturally experienced. This chapter builds on previous research into the value of visual images for communicating pain in the UK, which evidenced ways in which images can improve doctor–patient interaction. It discusses ways in which photographs co-created with people living with chronic pain can be catalysts for discussion of pain and suffering in a range of cultural contexts, including higher education and healthcare training. We draw on a pilot project in Delhi, India where images were used as stimuli to dialogue and exploration of shared understanding of pain and current work in UK higher education using visual and other participatory methods. Students have a chance to work with and discuss images which depict qualities and characters of pain. Through seeing and hearing about patients’ experiences of pain, students learn about the commonalities and diversities in people’s experiences of their bodies and minds and how these impact on lives. As future health professionals, their own responses to this are important. Chronic pain can be a disabling condition leaving people vulnerable, with their sense of self and how they are seen by others threatened. People living with pain have to (re)negotiate their identity, with themselves and others, to see who they can be, as well as what they can do in this new state. Exploration of this through visual arts and verbal participatory activities can provide otherwise untapped insights and understandings of the human condition and its diversity. Exploring ways in which this approach could be extended to and adapted to other contexts are part of our future plans.
