Abstract
Purpose
The purpose of this paper is to use an evaluation of a micro-place-based hot-spot policing implementation to highlight the potential issues raised by data quality standards in the recording and measurement of crime data and police officer movements.
Design/methodology/approach
The study focusses on an area of London (UK) which used a predictive algorithm to designate micro-place patrol zones for each police shift over a two-month period. Police officer movements are measured using GPS data from officer-worn radios. Descriptive statistics regarding the crime data commonly used to evaluate this type of implementation are presented, and simple analyses are presented to examine the effects of officer patrol duration (dosage) on crime in micro-place hot-spots.
Findings
The results suggest that patrols of 10-20 minutes in a given police shift have a significant impact on reducing crime; however, patrols of less than about 10 minutes and more than about 20 minutes are ineffective at deterring crime.
Research limitations/implications
Due to the sparseness of officer GPS data, their paths have to be interpolated which could introduce error to the estimated patrol dosages. Similarly, errors and uncertainty in recorded crime data could have substantial impact on the designation of micro-place interventions and evaluations of their effectiveness.
Originality/value
This study is one of the first to use officer GPS data to estimate patrol dosage and places particular emphasis on the issue of data quality when evaluating micro-place interventions.

Abstract
Purpose
This note aims to introduce a terminal guidance law that is able to compensate for evasive target maneuvers without estimating their acceleration.
Design/methodology/approach
The new guidance law is derived in the framework of linear-quadratic optimal control to ensure interception with minimum energy even in the presence of a target maneuver.
Findings
An explicit closed-form expression for the missile acceleration command is provided, which turns out to be a non-trivial extension of proportional navigation guidance. Simulation results against evasive maneuvers of various intensities are provided to compare the new law to classical ones and thus show the benefits of the proposed approach.
Originality/value
The proposed guidance law was not reported so far in the literature and provides a simple way to deal with evasive maneuvers.

Abstract
The purpose of this study was to research retail layout of a local super market. The five concepts of retail layout were used to determine if the super market was achieving an effective layout. To accomplish this study, we applied previous studies, conducted interviews, and made use of the store for our own research. After discovering that the local supermarket needed some improvements, recommendations were made to improve the supermarket from the customers’ point of view. The other objective of our study was to determine if the supermarket utilised floor space to maximise profitability per square foot. Our findings helped to verify whether the supermarket implemented an appropriate layout.

Abstract
Purpose
By using table tennis as an example and conducting an in-depth investigation into the impact of market demand factors on membership consumption of table tennis club members in the USA, the purpose of this paper is to illustrate the opportunities and marketing efforts needed for Asian sports to survive and thrive in North America, in which consumer demand factors assessing core program features of table tennis clubs were found to be very influential of cognitive, affective, and behavioral consumptions of table tennis club members.
Design/methodology/approach
Through conducting a review of literature, observations of club operations, and interviews of club administrators and club members representing various table tennis clubs, a preliminary questionnaire was formulated for this study. The initial questionnaire was submitted to a panel of five experts, for a test of content validity. By incorporating their suggestions, editing was made to improve a number of the items in the questionnaire. Data collection took place in two national table tennis tournaments, two local tournaments, and six table tennis clubs. Procedures in SPSS 19.0 (SPSS, 2009) and Mplus 5.21 were carried out for data analyses.
Findings
The findings of this study are that market demand factors would be significantly related to consumer perceived benefits and perceived value, and in turn related to consumer satisfaction of table tennis club membership. The market demand factors had a positive impact on perceived value and benefits confirmed the theoretical framework and previous research findings, which also made a practical sense that a table tennis club needs to offer product features and meet expectations of its current and potential members in order to enhance program value and benefits perceived by its members.
Originality/value
The past two decades have marked the speediest rise of a globalized sport production and consumption trend. In an era of globalized sport marketplace, sports have become a business commodity to meet the needs of commerce. For an Asian sport to penetrate into the North American marketplace as table tennis has done, it would be wise to develop regional network, strategies, product, and promotions. It is expected that table tennis as a popular Asian sport will continue being spread to other parts of the world; thus, the findings of this study have potential relevance to promoting table tennis globally.

Abstract
Purpose
Despite the increasing role of the data warehouse as a supportive decision-making tool in today's business world, academic research for measuring its effectiveness has been lacking. This paucity of academic interest stimulated us to evaluate data warehousing effectiveness in the organizational context of Jordanian banks.
Design/methodology/approach
This paper develops a theoretical model specific to the data warehouse system domain that builds on the DeLone and McLean model. The model is empirically tested by means of structural equation modelling applying the partial least squares approach and using data collected in a survey questionnaire from 127 respondents at Jordanian banks.
Findings
Empirical data analysis supported that data quality, system quality, user satisfaction, individual benefits and organizational benefits have made strong contributions to data warehousing effectiveness in our organizational data context.
Practical implications
The results provide a better understanding of the data warehouse effectiveness and its importance in enabling the Jordanian banks to be competitive.
Originality/value
This study is indeed one of the first empirical attempts to measure data warehouse system effectiveness and the first of its kind in an emerging country such as Jordan.

The purpose of this paper is to build a more scientific and refined collection assessment indicator system and examine the state of the collections, and adjusting collection development planning.
Design/methodology/approach
To analyze the weaknesses in the current assessment indicator system, advance the quality–utility–value Theory of collection assessment, introduce the advantages of the theory, use it to construct a collection assessment indicator system and clarify the content of each assessment indicator.
Findings
Empirical analysis of the foreign language collection of the National Library of China verified the scientific nature and feasibility of the assessment indicator system based on the quality–utility–value Theory.
Research limitations/implications
The indicator system should be more detailed according to the needs, and the scoring standard can be clearer.
Practical implications
According to the quality–utility–value Theory or based on such an assessment indicator system, libraries can build an indicator system related to their own libraries.
Social implications
Building a good collection assessment, it is very important In today’s library tight funds, after the outbreak of COVID-19. With the value dimension, the collection assessment of the library is more objective, comprehensive and three-dimensional.
Originality/value
This paper considers how to construct a collection assessment indicator system with the new theory, the quality–utility–value Theory; it is three-dimensional. Well, the collection value is not clearly measured and expressed in the indicator system before. Using this theory, this paper makes an empirical study on the evaluation of the foreign language collection of the National Library of China.

Abstract
Purpose
Customer identity and access management (CIAM) is a sub-genre of traditional identity and access management (IAM) that has emerged in the past few years to meet evolving business requirements. CIAM focuses on the connectivity with the customer when accessing any type of systems, on-premises and in the cloud, from registration to track. The purpose of this study is to introduce different dimensions of CIAM toward exploiting them in organizations.
Design/methodology/approach
Based on a thorough review of the relevant literature and semi-structured interview with six experts in the field of digital IAM the necessary data were gathered. Then through the use of content analysis technique, analytic codes and also categories and sub-categories of the data were generated.
Findings
Results indicate that four categories, namely, customer identity management, customer access management and information technology and business management are the most important factors affecting the identification of CIAM dimensions.
Originality/value
Organizations could avail of the proposed conceptual model toward identification and offering customized products and services solutions to their customers.

Abstract
In the discount store area, foreign large retailers such as Wal‐mart, Carrefour, and Costco fight hard with domestic retailers in Korea. The Korean customer is a judge in the centre of such a difficult fight. Therefore, foreign retailers who are willing to win the game should pay attention to what Koreans say and respond to the complaint as fast as they can. This study monitored e‐complaints of customers towards Korea Carrefour through analysing contents of the bulletin board in an anti‐Carrefour site. Upon examining e‐complaints by category and retail attributes, there were found to be more complaints in electrical goods and food and groceries by product category, and in employee attitudes and store atmosphere by retail attributes. The implications for successful retail strategies of foreign discount stores in Korea are discussed and further research is suggested.

Abstract
Purpose
The satisfaction‐trust paradigm has been recently criticized regarding its ability to deliver positive consumer behavioral outcomes. This study aims to argue that – amongst others – a reason for this unpleasant situation may be the failure of service managers to account for non‐linearities in the satisfaction‐trust paradigm.
Design/methodology/approach
The setting for this study was the supermarket retail channel. A total of 942 respondents were “intercepted” in supermarket stores, employing a face‐to‐face personal interviewing method. For the detection of curvilinear effects the study employed the two‐step single indicant method of Ping.
Findings
It is posited that consumer trust is an important intervening variable through which non‐linear service evaluation effects translate into word‐of‐mouth. Findings imply that investing resources in satisfaction programs do not do a good job in building positive word‐of‐mouth from a point on. Economic value evaluations and trust judgments seem to be both necessary and sufficient conditions for building consumer relationships.
Research limitations/implications
Theoretically, the work extends the relationship marketing research stream suggesting that curvilinear mechanisms are likely present in the well accepted satisfaction‐trust paradigm. Limitations of the study relate to the generalization of the findings in other sectors besides grocery retailing and its cross‐sectional nature.
Practical implications
The findings of this study suggest that relationship marketing managers would be ill‐advised in their investment decisions should they use a linear‐only terms trust model.
Originality/value
This article extends the trust literature in that it investigates whether consumer trust suffers from diminishing returns. Service providers who strive to build long‐term relationships with their customers may not do a good job if they continue to invest in trust determinants that present diminishing returns to scale.
