Abstract
SINCE THE INTRODUCTION of the hypoid gear as the right‐angled drive in automotive rear axles there has been a constant demand for specialised lubricants, particularly for running‐in purposes. Requirements are gradually and constantly becoming more severe and standards of performance adequate 5 or 10 years ago may be marginal today and unacceptable in the future.

Abstract
Purpose
The purpose of this paper is to examine the influence of reference data, input address quality, and crime type on completeness and positional accuracy of street geocoded crime events.
Design/methodology/approach
Existing data were analyzed using ArcGIS, including crime incident information, street network reference data, and address point and/or parcel reference data. Geocoding completeness was determined by the overall match rate. Positional accuracy was determined by comparing the Euclidian distance between street geocoded locations of crime events to the corresponding address point/parcel geocoded location.
Findings
Results indicate that match rates vary by reference data, input address quality, and crime type. Local street centerline files consistently produced match rates that were as good as – and in many cases superior to – other types of reference data, including commercial data. Greater variability in positional accuracy was observed across reference data when crime type and input address quality was considered, but results were consistent with positional accuracy analysis conducted using data from other disciplines.
Practical implications
Results provide researchers and practitioners with valuable guidance and insight into one of the most basic – albeit fundamental – procedures related to the spatio‐temporal analysis of crime, suggesting that reference data required to produce geocoded crime incidents successfully and of high quality does not necessarily mean a large financial investment on the part of law enforcement agencies or researchers interested in the geospatial analysis of crime.
Originality/value
Prior to this investigation, a comprehensive examination of the impact of data quality on geocoded crime events was absent from the literature.

Abstract
FOREWORD COMMUNICATION OF IDEAS and data leads to dross‐pollination in research, which can be as important as the bench work itself. Channels of communication are now highly developed and the growth of specialized symposia and conferences points to the continuing development of this important aspect of research. Those who move about meetings regularly can acquire a balanced understanding of what is going on in the many corners where research is being prosecuted. Those who make a habit of combing, methodically, the technical press can also arrive at some idea of the direction and speed of the currents flowing through a particular subject. There are, however, many technical men who find themselves too busy in their management sphere to keep abreast with either meetings or the scientific journals.

Abstract
Purpose
The purpose of this paper is to study the interrelationships among grocery store image, travel distance (TD), customer satisfaction, and behavioral intentions (BI) in a college town setting.
Design/methodology/approach
Surveys are given to undergraduate college student grocery shoppers in a Midwest college town. The 400 usable questionnaires are randomly divided into two parts: one subsample was used for exploratory factor analysis while the other (larger) subsample was used for confirmatory factor analysis and subsequently the structural path analysis.
Findings
Grocery store image is identified as a second‐order construct reflected by the three key components of merchandise attributes (MEA), store ambience and service (SAS), and marketing attractiveness (MGA). Although store image is an important driver of BI, its indirect effect through customer satisfaction is found to be substantially greater than its direct effect on BI. Interestingly, TD is positively related to satisfaction, which highlights the possibility for retailers to overcome the distance disadvantage.
Originality/value
As few studies have attempted to characterize the US grocery market in terms of the reasons for their choice, this exploratory study is unique because it investigates grocery shopping behavior in a traditional American college town. Specifically, the distinctive market factors (e.g. the relative scarcity of grocery retailers, their distance from campus, and the mix of grocer types in or around the Midwest college town) add value and contribute to the retailing literature.

Abstract
This research is to identify how user-generated contents (UGC) affect a pre-trip decision on the booking of a guesthouse among international travelers. Online surveys are conducted among social network users who have booked an ecolodge in the past year. A snowball sampling is used, which posts a questionnaire link in social networks including Twitter, Facebook, and Instagram in addition to travel blogs. This study indicates a positive relationship between UGC and lodging selection. UGC is considered as a significant predictor of booking an environmentally friendly guesthouse. Among the UGCs, travelers' review is the most important one influencing guesthouse selection. Future studies may focus on other IT potentials such as “Gamification” or other types of content such as “Podcasts” or “live videos” to engage independent travelers.

Abstract
Purpose
In England, climate change and sustainability education (CCSE) is predominantly taught with a focus on knowledge in school geography and science. However, whole-school approaches to CCSE exist which encompasses curriculum, campus, community and culture. Drawing on conceptualisations of the ecological approach to teacher agency we explored the ways in which the leadership of a whole-school approach to CCSE was implemented across four case study schools.
Design/methodology/approach
Four case study schools were identified as having implemented CCSE across the areas of classroom, culture, campus and community, with opportunities to share good practice. During visits to each school, we completed a series of 15 interviews with teachers who had roles leading geography (n = 4) and science (n = 4) curricular; school leaders (n = 4) and sustainability coordinators (n = 3). We engaged with a range of school curricula and policy materials and toured each site.
Findings
At the heart of an effective approach to whole-school CCSE are leaders who create the conditions for teachers to achieve agency and enact curriculum making as a social practice. School leaders themselves are critical in ensuring the culture, professional norms and expectations are established and nurtured. Over time, teachers are able to identify and create spaces of agency in relation to CCSE which reach beyond their immediate communities.
Originality/value
This research brings together teacher agency, curriculum making and leadership practices to better understand why some schools achieve agentic cultures as part of whole-school CCSE.

Abstract
While visual arts, drama, dance and music have been used to enhance literacy learning for many decades in preschool and primary classrooms, engaging with mobile learning can also provide many opportunities for young learners to explore and develop language and literacy. The use of mobile devices is of particular interest as technology has an impact on pedagogy and the mobility of digital devices provides many opportunities for engaged and meaningful literacy learning when teamed with the arts. In this chapter, we define the arts and their relationship with literacy learning before exploring a number of resources and practices for integrating their use in early learning settings.
