Discusses the issues associated with a surge in information demand in a relatively small organization. Introduces the idea of imaging and text retrieval to handle information demand. Discusses the criteria used by the Compassion in World Farming (CIWF) organization to make its decision on selecting a product. Presents situations in which use of the imaging and text retrieval system has had significant impact on the day‐to‐day conduct of business in the organization.

Consider an information processing algorithm that is designed to process an input data object onto an output data object via a number of successive internal {\it layers} and mappings between them. The possible activation state within each layer can be represented as a cube within Euclidean space of a high dimension (e.g. equal to the number of artificial neurons at that level). Multiple instances of such input objects produce a point cloud within each layer’s cube: this is the “representation of the reality” at that layer, as sampled by the set of input objects.

Most neural networks reduce the dimension of each layer’s cube from layer to successive layer. This gives the false impression of refining the inner representations of reality, distilling it down to fewer dimensions from which to discriminate or to infer outcomes (whatever is the aim). However, the representation of reality realised within each layer’s cube is a manifold, a curved subset embedded within it and of much lower dimension. Investigations show that such manifolds may not always be reducing in their local dimension. Instead, the manifold may become folded over and over, filling up further dimensions and creating non-realistic (unforeseeable) proximities.

We discuss some of the likely consequences of these relatively unforeseen characteristics and, in particular, the possible vulnerability of such algorithms to non-realistic perturbations. We consider a possible response to this issue.

New forms of calibration are necessary, using geometric/topological loss functions, as opposed to simple (variation-limiting) regularisation terms.

We apply persistent homology methods to understand how the images of the point cloud (representing the sampled reality) change as they pass from layer to layer.

Drawing on the theory of memory-dominant logic, this study aims to examine how the substantive staging of the servicescape, experience co-creation, experiential satisfaction and experience intensification affect experience memorability and hedonic well-being in the case of unmanned smart hotels.

An online survey was used, with the target respondents being hotel guests people aged 18 years and older who had been recent guests of the FlyZoo Hotel in Hangzhou, China. Data were collected online from 429 guests who had stayed in the hotel between April and June 2023. Data analysis was undertaken using structural equation modelling.

The results suggest that all the proposed four constructs are positive drivers of a memorable unmanned smart hotel experience. The relationship between the memorability of the hotel experience and hedonic well-being was found to be significant and positive.

Unmanned smart hotels should ensure that all smart technologies function effectively and dependably and offer highly personalised services to guests, allowing them to co-create their experiences. This will lead to the guest receiving a satisfying and memorable experience. To enable experience co-creation using smart technologies, unmanned smart hotels could provide short instructional videos for guests, as well as work closely with manufacturers and suppliers to ensure that smart technology systems are regularly updated.

This study investigates the antecedents and outcomes of a novel phenomenon and extends the concept of memorable tourism experiences to the context of unmanned smart hotels.

Positive behavioural support has been considered as a valuable alternative to residential care for children and adolescents with learning disabilities and behaviour that challenges. While recent evidence suggests it has a positive impact on behaviour and carer ability to cope, there is little evidence of its economic costs or benefits. The paper aims to discuss this issue.

An exploratory cross-sectional study was conducted to evaluate the cost of providing positive behavioural support to ten children and adolescents with learning disabilities and behaviour that challenges living in the community in Ealing, West London. Comparison was also made with the cost estimate of possible alternative support packages for children and adolescents with learning disabilities and behaviour that challenges in the UK, as obtained through a Delphi exercise.

Total cost of services per child was £1,454 per week for young people supported short-term, and £1,402 supported long-term. Children and adolescents were making use of a range of social care, education and health services. Over the full sample, half of the total cost was accounted for by education services. The Delphi exercise estimated the weekly cost of residential-based care as more expensive than the cost of community-based care for children and adolescents with learning disabilities and behaviour that challenges. At the end of the ITSBS, all ten children and adolescents initially at risk of imminent residential placement were living in the community with less service-intensive and less expensive support. This suggests that avoiding residential-based care could reduce costs in the long term.

Positive behavioural support has potential to support people with learning disabilities and behaviour that challenges in the community, leading to potential cost advantages. However, this is a small study and more robust research is needed.

Spotlights the body of work with regard to the sociology of AIDS showing how this has grown over the last two decades of the twentieth century. Indicates that sexually transmitted infections (STIs) are affected by patterns of sexual behaviour along with drug related practices. Cites the vulnerability of low socio‐economic groups to STIs, with the use of an explanatory figure with lots of detail within it. Summarizes that health research on inequality, particularly with regard to HIV and STIs would assist greatly in determining the relevant factors.
