Making sense of higher education: students as consumers and the value of the university experience

Abstract: In the global university sector competitive funding models are progressively becoming the norm, and institutions/courses are frequently now subject to the same kind of consumerist pressures typical of a highly marketised environment. In the United Kingdom, for example, students are increasingly demonstrating customer-like behaviour and are now demanding even more ‘value’ from institutions. Value, though, is a slippery concept, and has proven problematic both in terms of its conceptualisation and measurement. This article explores the relationship between student value and higher education, and, via study in one United Kingdom business school, suggests how this might be better understood and operationalised. Adopting a combined qualitative/quantitative approach, this article also looks to identify which of the key value drivers has most practical meaning and, coincidentally, identifies a value-related difference between home and international students.

Liquid marbles: principles and applications

Abstract: The ability of particles to adhere to a fluid–fluid interface can stabilize the formation of an emulsion. When the encapsulated fluid is a liquid and the fluid in which it is immersed is air, the object formed is called a “Liquid Marble”. Here we discuss how liquid marbles can be created, their fundamental properties and their transport and potential uses. We show how they arise naturally as an insect waste disposal system, from impact of droplets on powders and on hydrophobic soil, and in the mixing of particulate containing liquids. Our principal aim is to review research on macroscopic single marbles and their potential uses in sensors and droplet microfluidics. However, we also illustrate the similarity between liquid marbles, Pickering emulsions and “Dry Water”, and the potential application of assemblies of liquid marbles within cosmetics and pharmaceutical formulations. Finally, we discuss how modifying the surface structure of particles and providing heterogeneous surface chemistry on particles (e.g. Janus particles) might provide new types of liquid marbles and applications.

Engineering classification of karst ground conditions

Abstract: On a world scale, the dissolution of limestone and gypsum by natural waters creates extensive karst landforms that can be very difficult ground for civil engineers. Caves threaten foundation integrity, notably where their width is greater than their roof thickness. Sinkholes pose many problems, and are classified into six types, including subsidence sinkholes formed in soil cover within karst terrains. Rockhead morphology varies from uniform to pinnacled, also creating difficult ground to excavate or found upon. A proposed engineering classification of karst defines various complexities of ground conditions by the geohazards that they provide, mainly the caves, sinkholes and rockhead relief. Ground investigation techniques and foundation design philosophies are considered so that they are appropriate to the ground conditions provided by the different classes of karst.

The conceptualisation and measurement of DSM-5 Internet Gaming Disorder: the development of the IGD-20 Test.

Abstract: Background Over the last decade, there has been growing concern about ‘gaming addiction’ and its widely documented detrimental impacts on a minority of individuals that play excessively. The latest (fifth) edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) included nine criteria for the potential diagnosis of Internet Gaming Disorder (IGD) and noted that it was a condition that warranted further empirical study. Aim: The main aim of this study was to develop a valid and reliable standardised psychometrically robust tool in addition to providing empirically supported cut-off points. Methods A sample of 1003 gamers (85.2% males; mean age 26 years) from 57 different countries were recruited via online gaming forums. Validity was assessed by confirmatory factor analysis (CFA), criterion-related validity, and concurrent validity. Latent profile analysis was also carried to distinguish disordered gamers from non-disordered gamers. Sensitivity and specificity analyses were performed to determine an empirical cut-off for the test. Results The CFA confirmed the viability of IGD-20 Test with a six-factor structure (salience, mood modification, tolerance, withdrawal, conflict and relapse) for the assessment of IGD according to the nine criteria from DSM-5. The IGD-20 Test proved to be valid and reliable. According to the latent profile analysis, 5.3% of the total participants were classed as disordered gamers. Additionally, an optimal empirical cut-off of 71 points (out of 100) seemed to be adequate according to the sensitivity and specificity analyses carried. Conclusions The present findings support the viability of the IGD-20 Test as an adequate standardised psychometrically robust tool for assessing internet gaming disorder. Consequently, the new instrument represents the first step towards unification and consensus in the field of gaming studies.

A qualitative investigation of problem gambling as an escape‐based coping strategy

Abstract: Background. There has been a small but growing body, of largely quantitative research, that has examined problem gambling in the context of poor coping skills. These studies suggest that gambling may be used as an alternative method of coping that some will use to distract themselves from having to deal with problems in their lives. Objectives. To examine the role that gambling plays in the lives of problem gamblers and the extent to which it may be used as a means of coping. Design. Fifty problem gamblers, ranging in age from 18 to 63 years, with an average age of 39 years, were interviewed. The focus of the interview was upon the participant's accounts of how their gambling problem had developed and the role that gambling played in their lives. A structured grounded theory approach was utilized. Results. Following the selective coding process, ‘gambling to escape’ was identified as the core category. This state was achieved through ‘mood modification’, involving fantasies, dissociation and/or changes in arousal. For some problem gamblers seeking mood modification was their primary motivation. For others mood modification was sought as a means to cope with one or two other psychological and/or psychosocial states consisting of ‘filling the void’ and/or ‘avoiding problems’. Two other factors sometimes influenced the need to gamble, either directly through ‘control beliefs’ or through ‘cognitive regret’. Conclusions. Escape was the prime characteristic of the gambling experience that facilitated the continuation of problem gambling among the interviewed participants. In relation to these findings, the implications for prevention, intervention, treatment and future research are discussed.
