Abstract
Purpose
Dry eye syndrome is one of the most common reasons for eye-related discomfort which, without treatment, in some cases may even lead to corneal damage. Blinking, baseline and reflex lachrymation and drainage compromise the topical application of therapeutics demanding repeated, often hourly applications of common lubricants. In contrast, topically administered chitosan-N-acetylcysteine-based eye drops were reported to sustain on the ocular surface for more than 24 h. The thiolated biopolymer can interact with the corneal mucin layer thereby forming covalent disulphide bridges, which may contribute to extended residence times.
Design/methodology/approach
In this study, the tribological characteristics of four different lubricants including hyaluronic acid and chitosan-N-acetylcysteine containing commercially available eye drops were investigated. For this purpose, a representative test setup was developed, which mimics the contact between the cornea and the eyelid wiper. Gels with different elastic properties coated with a mucin layer were used as a substrate to mimic the corneal surface. Tests were conducted with a micro-tribometer, and friction values were recorded. Contact zones were characterized by X-ray photoelectron spectroscopy to investigate wear and thiol bonding on the surface.
Findings
Results revealed the lowest average coefficient of friction values for chitosan-N-acetylcysteine-based eye drops and substrate dependence of the test setup.
Originality/value
In this study, the authors introduced an in vitro system to test different types of eye drops so that chemical interaction with the mucin layer can be observed. These interactions change the tribological performance significantly and must be considered to have results relevant to the actual application.

Abstract
Purpose
The purpose of this paper is to examine the relationship between athletic participation and the acceptance of rape myths in an effort to further identify cultural and social institutions that may contribute to adherence to and glorification of rape culture.
Design/methodology/approach
A random sample of 685 first semester, university freshmen were surveyed about their high school sports participation and levels of rape myth acceptance (RMA). Linear regression models were estimated to examine the relationships between participation in sports, the type of sport participation and the acceptance of rape myths.
Findings
Those involved in athletics, generally, and those involved in team sports are more accepting of rape myths than are their counterparts. These results hold true for the full sample and for males and females, when examined separately. Participation in contact sports was not significantly predictive of RMA.
Practical implications
Athletics may provide a culture that is particularly prone to a belief in rape myths, which jeopardizes the integrity of collegiate sports. Policies should focus on changing offender behavior not victim behavior to create safer and more inclusive communities. Educating youth about the nature of rape myths and providing them with skills to resist such thinking is paramount. Focused programs and training could reduce the likelihood of accepting rape myths and, in turn, may make high school and college campuses safer.
Originality/value
This paper contributes to prior research by examining a sample of first semester university freshmen about their high school athletic participation and RMA. This research not only minimizes the effects of college level influences but also distinguishes between different forms of athletic involvement.

Abstract
The nutritive properties of various dietary components and their effects on health are regularly debated in the scientific literature and popular media. The study of the regular consumption of cake in relation to the risk of developing metabolic disorders is however an exciting new development in the field. This chapter suggests that cake consumption is amongst a number of factors that may explain The Ambridge Paradox: the extremely low incidence of metabolic disorders such as obesity and Type 2 diabetes observed in a small Borsetshire village. The chapter identifies 10 dietary and lifestyle habits observed in this population that may be beneficial for cardiovascular health, acting through a variety of mechanisms. Key amongst these may be the synergic properties of several biochemical components of cake, especially the phenolic compounds in varieties with a fruit-based element, such as lemon drizzle. The chapter concludes that the dietary and lifestyle habits of the Ambridge cohort show promise as a model for improving the metabolic health of wider populations. In particular, it suggests that cake consumption may be a promising therapeutic supplement to prevent and even treat metabolic disorders.

Abstract
This experimental study investigates the connotative (measured) meaning of the concept “auditor independence” within three audit engagement case contexts, including two acknowledged in the literature to represent significant potential threats to independence. The study’s research design utilises the measurement of meaning (semantic differential) framework originally proposed by Osgood et al. (1957). Findings indicate that research participants considered the concept of independence within a two factor cognitive structure comprising “emphasis” and “variability” dimensions. Participants’ connotations of independence varied along both these dimensions in response to the alternative experimental case scenarios. In addition, participants’ perceptions of the auditor’s independence in the three cases were systematically associated with the identified connotative meaning dimensions.

Abstract
Flexibility is a basic requirement to cope with complexity and dynamics. The aim of this chapter is to analyze to which extent self-organization can support integrating flexibility in the processes of competence-building and competence-leveraging. The objective of this discussion is therefore to deduce possible contributions of the concept of self-organization to a strategic competence-based management in regard to effects of flexibilization.

Abstract
In the 1990s, North American archivists and records managers shifted some of their concern with electronic records and record keeping systems to conducting research about the nature of these records and systems. This essay describes one of the major research projects at the University of Pittsburgh School of Information Sciences, supported with funding from the National Historical Publications and Records Commission. Specifically, the essay focuses on the project's four main products: recordkeeping functional requirements, production rules to support the requirements, metadata specifications for record keeping, and the warrant reflecting the professional and societal endorsement of the concept of the recordkeeping functional requirements.

Abstract
Given the resources being spent on corporate identity development, it is disappointing that the mainstream marketing texts and journals afford it little space. Development of an understanding of corporate identity and image is sought. Corporate identity is projected by organisations and services to shape the image held of the organisation by its publics. In the absence of tangibility, as is the case in service marketing, corporate image has a powerful role. For these reasons, financial services marketers need to treat corporate identity as a strategic marketing issue. How this may be done is theorised and a case study of Allied Irish Bank plc is used as an illustration of corporate identity development in practice. Given the company‐specific and industrywide changes that have occurred in financial services, the corporate identity issues raised will apply to many businesses within that industry.

Abstract
VINE is a Very Informal Newsletter produced three times a year by the Information Officer for Library Automation and financed by the British Library Research & Development Department. It is issued free of charge on request to interested librarians, systems staff and library college lecturers. VINE'S objective is to provice an up‐to‐date picture of work being done in U.K. library automation which has not been reported elsewhere.
