The availability of the National Institute of Mental Health (NIMH) database has raised many questions concerning strategies for gaining efficient retrieval of relevant citations by subject. Because NIMH is only available online and users lack search aids necessary in providing both descriptive and general content information, a need exists to summarize essential understandings and to clarify approaches to retrieval of information from this database. This study investigates the feasibility of using NIMH for searching education and education‐related fields, and compares its coverage in these areas with ERIC (Educational Resources Information Center) and PsychINFO. It also aims to identify potential subjects worthy of inquiry in NIMH.

“What above all marks out a reference book from other works is the way it is arranged: it must be deliberately designed for ease of consultation rather than for continuous reading.” “Ease of consultation,” an essential component for reference books, as stated by Gavin Higgens in his book Printed Reference Material, is a criterion that reference librarians often consider as they use reference books to answer questions. Reference book publishers have long used various special features designed to speed access to information in these sources. Thumb indexes for dictionaries come to mind immediately when one thinks of this type of special feature. Some publishers include printed index tabs listing sections or subject categories, as in The National Directory of Addresses and Telephone Numbers, where the tabs are on a separate sheet of paper to be attached to the appropriate pages by the librarian. Margin or edge indexes in the Washington Information Directory or in the Government Reports Announcements & Index provide quick identification of sections to turn to, and are easy to use for both patrons and librarians. Color can also be used as a device to distinguish different sections of a reference tool. Literary Market Place and Magazine Industry Market Place, for example, use yellow pages to separate the main body from the quick reference directory of names and telephone numbers. Of course, these devices are not substitutions for indexes or tables of contents, but are helpful to librarians and users who want to be more self‐sufficient. The editor of this column would like reference book publishers to consider including more of these devices in their publications. Readers are invited to write to this editor with other examples of special features which promote “ease of consultation” of reference serials.

Optical storage media can facilitate the type of research done in academic libraries. This article describes InfoTrac, a database on laserdisc, and reports on its reception at the University of Dayton.

The purpose of this study is to examine how supply chain strategy affects a firm's sustainability performance and how the strength of that relationship is influenced by managerial authentic leadership (AL) and its associated impact on interorganizational citizenship behavior (ICB).

Building on the intersection of three theories: organizational ambidexterity, AL and ICB, a mediated moderation model is developed and tested using structural equation modeling based on the responses from a cross-sectional survey administered by the authors.

The results reveal that an ambidextrous supply chain strategy is positively related to firm sustainability performance and this relationship is strengthened by AL. Furthermore, this study finds that this moderating relationship is partially mediated by ICB.

To the best of the authors’ knowledge, this paper is among the first to empirically test the effect of supply chain ambidexterity on sustainability performance by explicitly considering how leadership characteristics can both directly and indirectly affect the efficacy of this relationship. The findings complement existing literature by providing novel insights into the ability of firm supply chain strategy to affect sustainability performance.

Visual inspection remains the dominant method of assessing component lead solderability and finished board solder joint quality. In recent years the wetting balance has received much attention as an attractive alternative to the inherently subjective visual inspection method of assessing component termination solderability. Whether direct visual inspection or wetting balance methods are used, the method can be shown to be effective only if the results are in agreement with board‐level soldering performance. This paper addresses the issue of the agreement of visual board‐level solder joint quality with both visual ‘dip and look’ solderability assessment and wetting balance measurement of the components prior to board assembly. A description of visual ‘dip and look’ solderability test assessment and of wetting balance methodology for components is presented, and a compendium of wetting balance tests and indices are documented in the Appendix. The experimental strategy employed is outlined, and details of the experimental technique (including the equipment, materials and component sample preparations) are provided. The experimental results present a comparison of both ‘dip and look’ visual solderability assessment and wetting balance measures with regard to actual board‐level soldering performance. The ability of the various assessment methods to predict board level defects is also explored.

Individual differences are critical in determining how individuals think and behave in different ways. The purpose of this paper is to explore the effect of individual differences on users’ perceptions of print and electronic resources in terms of ease of use, usefulness and usage in the hopes that a better understanding of these effects can help Chinese university libraries to meet the diversified information needs of their users more specifically and appropriately so that the second-level capability divide and third-level outcome divide of library information resources can be much reduced.

Data collected from 273 library users were used for data analysis. The independent samples t-test, one-way analysis of variance (ANOVA) and two-way ANOVA were employed. Meanwhile, the quantitative analysis is supplemented by the qualitative interviews which present richer data about the use of specific types of print and electronic resources.

The effect of basic characteristics (gender, age, field) and experience (experience with library print resources, experience with library electronic resources, which library resources were used first) on users’ perceptions of print and electronic resources in terms of ease of use, usefulness and usage was explored and discussed. Meanwhile, the two-way interaction effect was examined and 13 significant interaction effects were presented.

Building on the digital divide, this study examines ease of use, usefulness and usage in terms of individual differences which cover not only basic characteristics but also experience and two-way interaction, which the authors think provides a new view for library information resources research and practice alike in China.

The sport consumer experience is becoming an important aspect to sport center’s management. From this point, the purpose of this paper is to explore and examine the relationship between sport centers’ absorptive capacity and sport consumer experience, proposing that internal knowledge management processes act as mediators in this relationship.

The study offers empirical insights by applying the consistent PLS algorithm (PLSc-SEM) in an analysis of data from 156 sport centers in Andalusia (Spain) and a sample of 3,150 sport users from these sport centers.

The results demonstrate that a sport center’s absorptive capacity for external knowledge is crucial for enhancing the sport consumer experience and also that this effect requires additional knowledge management, such as the sport center’s knowledge storage and knowledge application.

The practical implication for sport center managers is that knowledge management processes have a very strong influence on the sport consumer experience, when they are managed in a sequential way.

The main value of this paper is draw conclusions using a study of sport managers and sport consumers to increase value experience of those ones.

The purpose of the paper is to describe the evolving regulatory structures of the civilian unmanned aerial vehicle (UAV) in India and Japan, not yet fully developed to regulate the deployment of the UAV. India and Japan are at the forefront to overhaul the respective regulatory framework to address issues of accountability, responsibility and risks associated with the deployment of UAV technologies.

In-depth interviews are conducted both in Japan and India to gather primary data based on the snowball sampling method. The paper addresses questions such as what is the current scenario of civilian UAV deployment in India and Japan. What are the regulation structures for Civil UAV deployment and operation and how they differ in India and Japan? What are the key regulatory challenges for Civil UAV deployment in India? How regulation structure enables or inhibits the users and operators of Civil UAVs in India? What are mutual learnings concerning UAV regulations?

Findings reveal that the Indian regulations address issues of responsibility by imparting values of privacy, safety, autonomy and security; Japanese regulation prefers values of trust, responsibility, safety and ownership with more freedom to experiment.

The study on civilian UAV regulatory framework is a new and innovative work embedded by the dimensions of responsibility and accountability from a responsible innovation perspective. The work is a new contribution to innovation literature looked at from regulatory structures. Field visits to both Japan and India enrich the study to a new elevation.

The soil water retention curve (SWRC) and unsaturated hydraulic conductivity (UHC) are crucial indices to assess hydraulic properties of porous media that primarily depend on the particle and pore size distributions. This study aims to present a method based on the discrete element model (DEM) and the typical Arya and Paris model (AP model) to numerically predict SWRC and UHC.

First, the DEM (PFC^3D software) is used to construct the pore and particle size distributions in porous media. The number of particles is calculated according to the AP model, which can be applied to evaluate the relationship between the suction head and the moisture of porous media. Subsequently, combining critical path analysis (CPA) and fractal theory, the air entry value is applied to calculate the critical pore radius (CPR) and the critical volume fraction (CVF) for evaluating the unsaturated hydraulic conductivity.

This method is validated against the experimental results of 11 soils from the clay loam to the sand, and then the scaling parameter in the AP model and critical volume fraction value for many types of soils are presented for reference; subsequently, the gradation effect on hydraulic property of soils is analyzed. Furthermore, the calculation for unbound graded aggregate (UGA) material as a special case and a theoretical extension are provided.

The presented study provides an important insight into the relationship between the heterogeneous particle and hydraulic properties by the DEM and sheds light on the directions for future study of a method to investigate the hydraulic properties of porous media.
