Abstract
Purpose
The purpose of this paper is to investigate the influence of question type (open-ended, prompted, reverse order and chronological order recall) on children’s ability to maintain a truth or a lie in a two-part mock-courtroom study.
Design/methodology/approach
In total, 96 children (M age=131.00 months) between 9 and 12 years of age were asked to testify about an interaction with a research assistant the week prior. They were assigned to one of four conditions (true/false×assertion/denial).
Findings
Results indicate that question type has an influence on children’s ability to maintain their condition. Results also indicate that regardless of question type, children have difficulty recalling information sequentially.
Practical implications
Implications of the current research support the use of various question types, including increasing the cognitive load demands, when interviewing children.
Originality/value
To date, this is the first study to investigate the use of reverse order questioning in a courtroom study with children.

Abstract
Purpose
Automatic modulation recognition (AMR) is a challenging problem in intelligent communication systems and has wide application prospects. At present, although many AMR methods based on deep learning have been proposed, the methods proposed by these works cannot be directly applied to the actual wireless communication scenario, because there are usually two kinds of dilemmas when recognizing the real modulated signal, namely, long sequence and noise. This paper aims to effectively process in-phase quadrature (IQ) sequences of very long signals interfered by noise.
Design/methodology/approach
This paper proposes a general model for a modulation classifier based on a two-layer nested structure of long short-term memory (LSTM) networks, called a two-layer nested structure (TLN)-LSTM, which exploits the time sensitivity of LSTM and the ability of the nested network structure to extract more features, and can achieve effective processing of ultra-long signal IQ sequences collected from real wireless communication scenarios that are interfered by noise.
Findings
Experimental results show that our proposed model has higher recognition accuracy for five types of modulation signals, including amplitude modulation, frequency modulation, gaussian minimum shift keying, quadrature phase shift keying and differential quadrature phase shift keying, collected from real wireless communication scenarios. The overall classification accuracy of the proposed model for these signals can reach 73.11%, compared with 40.84% for the baseline model. Moreover, this model can also achieve high classification performance for analog signals with the same modulation method in the public data set HKDD_AMC36.
Originality/value
At present, although many AMR methods based on deep learning have been proposed, these works are based on the model’s classification results of various modulated signals in the AMR public data set to evaluate the signal recognition performance of the proposed method rather than collecting real modulated signals for identification in actual wireless communication scenarios. The methods proposed in these works cannot be directly applied to actual wireless communication scenarios. Therefore, this paper proposes a new AMR method, dedicated to the effective processing of the collected ultra-long signal IQ sequences that are interfered by noise.

Abstract
A classification scheme by its notation does not do more than locate the subject; therefore, after the books are classified according to the scheme adopted, a secondary arrangement must be provided for the shelves, whereby books in a given class may be arranged in some order to accelerate finding and to differentiate one book from another. There are several methods in vogue of so arranging books in a given class, but one's choice will be, to some extent, determined by the System of issue in use. The usual methods are by:—

Abstract
The current paradigm of time in the marketing literature is one where time is linear, quantifiable and predominantly chronological in nature. This is merely one construct of one aspect of time and a construct that is largely specific to a western, industrialized society. The associated theory of time allocation assumes individuals seek to compress time‐consuming activities. Time compression and the speeding‐up of activities are a current feature of both consumer and industrial marketing. Discusses other constructs of time, drawn from the fields of sociology, psychology and anthropology. Time is two concepts, duration and succession. Time can be cyclical rather than linear and is seen as such within concepts such as the product life cycle. It can also be episodic, as in the celebration of events. Questions whether time is ever truly linear, as our perception of duration varies with the content of the activities that fill that duration. This suggests an alternative to time compression, to fill empty time so as to make duration appear faster. Discusses the limitations of current theory and concepts. Suggests a relativistic approach of describing or scoping time‐consuming activities as an alternative towards developing a more universal understanding of time allocation. Argues that progress is needed in the area to meet the needs of a society where time in general and leisure time in particular are ever more significant.

Abstract
Job analysis is the common basis for designing a training course or programme, preparing performance tests, writing position (job) descriptions, identifying performance appraisal criteria, and job restructuring. Its other applications in human resource development include career counselling and wage and salary administration. Job analysis answers the questions of what tasks, performed in what manner, make up a job. Outputs of this analytical study include: (a) a list of the job tasks; (b) details of how each task is performed; (c) statements describing the responsibility, job knowledge, mental application, and dexterity, as well as accuracy required; and (d) a list of the equipment, materials, and supplies used to perform the job. Various techniques for conducting a job analysis have been used. Each has its advantages and disadvantages. As a result, different techniques or combinations of techniques are appropriate to different situations. The combined on‐site observation and individual interview techniques are recommended for industrial, trade, craft, clerical, and technical jobs because they generate the most thorough and probably the most valid information. A job analysis schedule is used to report the job information obtained through observations and individual interviews. The schedule provides a framework of 12 items in which to arrange and describe important job analysis information. These 12 items are organised into four sections. Section one consists of items one through four. These items identify the job within the establishment in which it occurs. The second section presents item five, the work performed. It provides a thorough and complete description of the tasks of the job. The Work Performed section describes what the job incumbent does, how it is done, and why it is done. Section three presents items six through nine. These are the requirements placed on the job incumbent for successful performance. It is a detailed interpretation of the basic minimum (a) responsibility, (b) job knowledge, (c) mental application, and (d) dexterity and accuracy required of the job incumbent. The fourth section includes three items which provide background information on the job. These items are: (a) equipment, materials and supplies; (b) definitions of terms; and (c) general comments. Appendix A is a glossary of terms associated with job analysis. It is provided to facilitate more exacting communication. A job analysis schedule for a complex and a relatively simple job are included in Appendices B and C. These examples illustrate how important job analysis information is arranged and described. Appendix D provides a list of action verbs which are helpful when describing the manipulative tasks of a job.

Abstract
Purpose
The purpose of this paper is to examine the extent to which presence, media richness, and narrative experiences yield the highest experiential value in augmented-reality interactive technology (ARIT).
Design/methodology/approach
A survey is performed to collect data. Valid questionnaires of 344 ARIT users are identified. The hypothesized associations are analyzed using structure equation modeling.
Findings
Empirical results indicate that narrative experience induces a higher experiential value than other simulative experiences, including presence and media richness.
Practical implications
Results of this study provide a valuable reference for managers attempting to design an ARIT process in order to optimize the experiential value in various online simulation environments.
Originality/value
This study adopts an integrated framework that incorporates narrative theory, media richness theory, and presence in the online ARIT. Exactly how narrative experience, media richness, and presence affect the formation of experiential value in the ARIT process is explored as well.

Abstract
Purpose
Aims to describe systematically the characteristics of weblogs (blogs) – frequently modified web pages in which dated entries are listed in reverse chronological sequence and which are the latest genre of internet communication to attain widespread popularity.
Design/methodology/approach
This paper presents the results of a quantitative content analysis of 203 randomly selected blogs, comparing the empirically observable features of the corpus with popular claims about the nature of blogs, and finding them to differ in a number of respects.
Findings
Notably, blog authors, journalists and scholars alike exaggerate the extent to which blogs are interlinked, interactive, and oriented towards external events, and underestimate the importance of blogs as individualistic, intimate forms of self‐expression.
Originality/value
Based on the profile generated by the empirical analysis, considers the likely antecedents of the blog genre, situates it with respect to the dominant forms of digital communication on the internet today, and suggests possible developments of the use of blogs over time in response to changes in user behavior, technology, and the broader ecology of internet genres.

Abstract
THE centenary of the birth of Edward Edwards is an event of great interest to all persons interested in the public library movement. Elsewhere in our columns we print a brief sketch of the life and work of “the chief pioneer of municipal public libraries.” The date generally accepted as that of his birth, December 14th, is regarded by some as doubtful, but is probably near enough for practical purposes. His retiring disposition resulted in the record of his life being doubtful or broken in places. The late Thomas Greenwood—another great library pioneer who has gone—collected all that could be collected in his valuable biography of Edward Edwards. It was his main regret that he could not obtain an authentic portrait of Edwards, and this regret we must all share, for a portrait brings reality to a verbal description. By the time these words appear in print, the Manchester Libraries Committee and the Library Assistants' Association will each have paid public tribute to the memory of Edward Edwards, and their example will have been followed in private by all other library workers having any regard for the history of their calling.

Abstract
TINlib has been on the market for two years and is in use in some 30 libraries in the UK for cataloguing and retrieval. The system was developed by Information Management & Engineering Ltd (IME), a British company specialising in database design. In November 1987, a subsidiary to IME was formed, called Information Made Easy (which can be rather dubiously shortened to IM Easy), which handles the marketing, sales and support of IME products in the UK. The system is also marketed in Europe and North America, and over 150 systems are now in use worldwide.
