The growth of the hypermarket and superstore has been one of the retail phenomena of the past few years. Peter Jones estimates that in the UK these large units have provided gross floorspace equivalent to 20 shopping centres the size of Brent Cross. Looking at future trends, he suggests there may be a polarisation between the large hypermarket selling both food and non‐food, and the smaller superstore concentrating on high volume food sales. This is an edited version of a paper Peter Jones presented to an URPI conference on “Retail Planning in the 1980s” earlier this year. A full report on the conference will be published by the unit later this year.

Presents a standard data format for describing and interpolating 3‐D human body shapes from data collected by a 3‐D body scanner. The body data were treated as a series of horizontal cross‐sections. Each cross‐section was described by 16 data points. The 3‐D surface can be calculated by interpolating between these sections. This procedure allowed editing and manipulation of raw scanned data, as well as substantial data reduction. Horizontal cross‐sections of the body were chosen to correspond to particular anatomical surface landmarks, rather than distances from a reference point. Hence, each data element described a particular anatomical location, irrespective of body shape and size. This feature allowed comparison and averaging of 3‐D shapes, greatly enhancing the application of 3‐D scanned data. The standard data format allows 3‐D scanned data to be transferred into CAD/CAM systems for automated garment design and manikin manufacture.

Research has shown that for young adults, marital attitudes (e.g., desire, importance, and expectation) are associated with relationship quality. However, how this association plays out for young adults of color is less known. Additionally, the influence of skin tone perception on the relationship between marital attitudes and relationship quality remains understudied. To explore these associations, the authors examined African American and Latinx young adults (N = 57, M_age = 20.71 years, SD = 1.28; 75.4% female) attending a Midwestern university. Exploratory results indicated that marital expectations were positively associated with relationship quality in that young adults who expected to marry one day, reported greater relationship satisfaction, commitment, and intimacy in their current relationships. Additionally, skin tone perception moderated the association between marital attitudes and relationship quality in two ways (i.e., between expectations and satisfaction and between importance and intimacy). Collectively, findings suggest that differing levels of marital attitudes and skin tone perception contributes to young adults’ perceptions of relationship quality. Considering these psychological factors of attitudes, skin tone perception, and relationship quality, together with systemic racial/ethnic discrimination, the authors discuss future research and practice considerations.

The purpose of this practice briefing paper is to provide an exploratory review of the sustainability agendas being addressed and publicly reported by the UK's leading data centre operators.

The paper begins with a short discussion of the characteristics of sustainability and an outline of the origins and development of data centres within the UK. The paper draws its empirical material from the most recent information on sustainability posted on the UK's leading data centre operators' corporate web sites.

The findings reveal that all the UK's leading data centre operators provide only limited information on their commitment to sustainability with the dominant focus being on its environmental dimension and with little attention being paid to social and economic issues. More critically the authors argue that these commitments are driven more by the search for efficiency gains, that they are couched within existing business models centred on continuing growth and that as such the UK's leading data centre operators are pursuing a “weak” rather than a “strong” model of sustainability.

The paper suggests that leading data centre operating companies may need to extend their sustainability reporting and to introduce external assurance procedures.

The paper provides an accessible review of the sustainability agendas being pursued by the UK's leading data centre operators and as such it will interest academics, students and practitioners interested in both sustainability and data centre operations and developments.

Whether the recent pressure for more out‐of‐town shopping appears to be easing in favour of further revitalisation of the inner city centre is discussed by involved interlocutors, both at local and at ministerial level. Amongst other relevant aspects of retail development, the pros and cons of superstores operating side by side with small businesses in town centres are examined.

The aircraft’s tyres are forced to spin up at touchdown. A considerable amount of frictional energy will be converted into heat, raising the tread temperature and leading to thermal wear. This study aims to develop a model to analyse the tread heat and discuss the effectiveness of two wear reduction methods.

The tread temperature is calculated using Laplace’s Equation. The efficiency of pre-rotation and soft landing in reducing tyre heat is studied using a developed three-dimensional heatmap method.

The result indicates that pre-rotation can significantly lower landing gear’s heat generation at touchdown. The soft landing, instead, has an insignificant or counterproductive effect.

The pre-rotation can significantly increase the tyre’s lifespan and cut the replacement cost. The emission of tyre particles into the environment can be reduced to protect the planet and human health.

Few studies have used a theoretical model to estimate the tread temperature. The existing studies have only dealt with the maximum tread temperature or the tread centreline temperature, which is insufficient to discuss the heat across the entire tread. However, the heatmap method in this paper can do the job.

Due to the static condition of the wheels at touchdown, they skid on the runway, which may cause the tyres to burn and wear. This phenomenon occurs in a fraction of a second, known as the spin-up period. The purpose of this paper is to introduce a new strategy to reduce the horizontal force, tyre temperature and wear during the spin-up period.

First, the dynamics of two different phases of landing, namely, spin-up and breaking phases, are reviewed. Second, a strategy to prevent excessive temperature and wear of the tyre is presented.

It is found that using a lubricant and coolant, such as water, at the spin-up stretch of the runway is a simple and practical solution to prevent excessive temperature and wear of the tyre. It is revealed that, despite increasing the spin-up period, the rise of the tyre temperature is eliminated and the material properties are preserved for effective braking. A rough quantitative analysis demonstrates that the wetting of tyres in the spin-up phase decreases the loads and tyre wear effectively.

Wetting the touchdown region of the runway without significant areas of standing water is the most practical strategy with the technology available today.

A new strategy is presented for landing with reduced tyre wear. It is the hope that this paper can inspire continuous efforts to realize the implementation of the strategy.
