The early 1990s are not the best of times to operate an academic library collection management unit. Financial woes abound: the escalating cost of materials (particularly serials), the continued proliferation of print sources, and the explosive development of expensive electronic media all conspire to increase the pressure on already strained acquisitions budgets. The problems are not exclusively fiscal, however. There appears to be a new and growing personnel problem: the difficulty of recruiting capable collection management staff.

Few issues in recent times have so provoked debate and dissention within the library field as has the concept of fees for user services. The issue has aroused the passions of our profession precisely because its roots and implications extend far beyond the confines of just one service discipline. Its reflection is mirrored in national debates about the proper spheres of the public and private sectors—in matters of information generation and distribution, certainly, but in a host of other social ramifications as well, amounting virtually to a debate about the most basic values which we have long assumed to constitute the very framework of our democratic and humanistic society.

The best‐selling book Megatrends, written by John Naisbitt, has been cited in numerous library and information science publications and talks since its appearance in 1982 Megatrends was bound to capture the attention of the librarians, since it boldly proclaims on page one that no shift “is more subtle, yet more explosive” than the change from an industrial to an information society. It has further appeal because many of the changes documented in Megatrends can be observed in libraries and the institutions and organizations they serve; moreover, the trends provide a framework from which to assess the status and direction of the information professions. This article will examine the several megatrends as they apply to the electronic library and will suggest appropriate plans of action.

Librarians have lavished years of scholarship on the subject of collection development. The rewarding process of organizing and building a relevant and competitive collection is one of librarianship's more rewarding jobs.

Secondary publishers respond to Internet challenge Two services have been launched that aim to combine formal published information with data offered via World Wide Web sites. Engineering Information (Ei) and Cambridge Scientific have employed editors to select sites and to check that they are still current, and are combining them with their own databases.

The purpose of this article is to provide a review of the most recent literature concerning document supply and related matters.

Includes the reading of over 140 published works, including journals, monographs, reports and web sites.

Finds that usage statistics are still not giving a clear indication of the importance of document supply but it is confirmed that the large proportion of demand comes from a small number of titles. Institutional repositories are here to stay and expanding. Experience of e‐journals is appearing in the published literature with greater frequency with some interesting conclusions. Copyright and digital rights management (DRM) remain fraught areas.

Provides a useful source of information for librarians and others interested in document supply and related matters.

The purpose of this paper is to propose an efficient computational technique, which uses Haar wavelets collocation approach coupled with the Newton-Raphson method and solves the following class of system of Lane–Emden equations:

To deal with singularity, Haar wavelets are used, and to deal with the nonlinear system of equations that arise during computation, the Newton-Raphson method is used. The convergence of these methods is also established and the results are compared with existing techniques.

The authors propose three methods based on uniform Haar wavelets approximation coupled with the Newton-Raphson method. The authors obtain quadratic convergence for the Haar wavelets collocation method. Test problems are solved to validate various computational aspects of the Haar wavelets approach. The authors observe that with only a few spatial divisions the authors can obtain highly accurate solutions for both initial value problems and boundary value problems.

The results presented in this paper do not exist in the literature. The system of nonlinear singular differential equations is not easy to handle as they are singular, as well as nonlinear. To the best of the knowledge, these are the first results for a system of nonlinear singular differential equations, by using the Haar wavelets collocation approach coupled with the Newton-Raphson method. The results developed in this paper can be used to solve problems arising in different branches of science and engineering.

Congruent with the world-wide call to combat global warming concerns within the context of advancements in smart technology, artificial intelligence, robotics, algorithms (STARA), and digitalisation, organisational leaders are being pressured to ensure that talented employees are effectively managed (nurtured and retained) to curb the potential risk of staff turnover. By managing such talent(s), organisations may be able to not only retain them, but consequently foster environmental sustainability too. Equally, recent debates encourage the need for teams to work digitally and interdependently on set tasks, and for leaders to cultivate competencies fundamental to STARA, as this may further help reduce staff turnover intention and catalyse green initiatives. However, it is unclear how such turnover intention may be impacted by these actions. This paper therefore, seeks to investigate the predictive roles of green hard and soft talent management (TM), leader STARA competence (LSC) and digital task interdependence (DTI) on turnover intention.

The authors used a cross-sectional data collection technique to obtain 372 useable samples from 49 manufacturing organisations in Nigeria.

Findings indicate that green hard and soft TM and LSC positively predict turnover intention. While LSC amplifies the negative influence of green soft TM on turnover intention, LSC and DTI dampen the positive influence of green hard TM on turnover intention.

Our study offers novel insights into how emerging concepts like LSC, DTI, and green hard and soft TM simultaneously act to predict turnover intention.

The purpose of this paper is to identify significant factors of environmental variables and pollutants that have an effect on PM_2.5 through wavelet and regression analysis.

In order to provide stable data set for regression analysis, multiresolution analysis using wavelets is conducted. For the sampled data, multicollinearity among the independent variables is removed by using principal component analysis and multiple linear regression analysis is conducted using PM_2.5 as a dependent variable.

It is found that few pollutants such as NO₂, NO_x, SO₂, benzene and environmental factors such as ambient temperature, solar radiation and wind direction affect PM_2.5. The regression model developed has high R² value of 91.9 percent, and the residues are stationary and not correlated indicating a sound model.

The research provides a framework for extracting stationary data and other important features such as change points in mean and variance, using the sample data for regression analysis. The work needs to be extended across all areas in India and for various other stationary data sets there can be different factors affecting PM_2.5.

Control measures such as control charts can be implemented for significant factors.

Rules and regulations can be made more stringent on the factors.

The originality of this paper lies in the integration of wavelets with regression analysis for air pollution data.
