Abstract
I read with interest ‘A Field Review of ‘O’‐level Chemistry Textbooks’ by Dr Michael Bassey. A short time before, I had read the enclosed review of Dr Pollock's book, ‘A Practical School Chemistry’ which appeared in Catholic Teachers Journal. You will notice it refers to many errors of fact and concludes that the book is unsuitable for use in schools at any level. Yet this is one of the best six recommended by Dr Bassey. It would appear that Dr Bassey has probably been so intent on the style and contents of each book that he has not been able to read them in detail, I know it is not unusual for reviewers to differ, out when one thoroughly recommends where another can find nothing good to say, one wonders what reliance to place upon them. I should be interested in Dr Bassey's comments on the matter.

Abstract
This paper seeks to explain the jury’s verdict of acquittal in the bizarre case of eccentric millionaire Robert Durst, who was charged with the murder of Morris Black after Black’s body parts were found floating in Galveston Bay off the coast of Texas. Though an analysis of a portion of the defense’ closing argument, this paper examines the Durst defense team’s strategy of directing the jury’s attention to a single event – the confrontation that resulted in Black’s death – in order to effect a shift in focus that allowed them to use “reasonable doubt” to leverage their argument that the prosecution had not met its burden of proof. This paper demonstrates how this strategy acted to construct the “unreasonable doubt” that resulted in the jury’s verdict.

Abstract
Purpose
With the advancements in photo editing software, it is possible to generate fake images, degrading the trust in digital images. Forged images, which appear like authentic images, can be created without leaving any visual clues about the alteration in the image. Image forensic field has introduced several forgery detection techniques, which effectively distinguish fake images from the original ones, to restore the trust in digital images. Among several forgery images, spliced images involving human faces are more unsafe. Hence, there is a need for a forgery detection approach to detect the spliced images.
Design/methodology/approach
This paper proposes a Taylor-rider optimization algorithm-based deep convolutional neural network (Taylor-ROA-based DeepCNN) for detecting spliced images. Initially, the human faces in the spliced images are detected using the Viola–Jones algorithm, from which the 3-dimensional (3D) shape of the face is established using landmark-based 3D morphable model (L3DMM), which estimates the light coefficients. Then, the distance measures, such as Bhattacharya, Seuclidean, Euclidean, Hamming, Chebyshev and correlation coefficients are determined from the light coefficients of the faces. These form the feature vector to the proposed Taylor-ROA-based DeepCNN, which determines the spliced images.
Findings
Experimental analysis using DSO-1, DSI-1, real dataset and hybrid dataset reveal that the proposed approach acquired the maximal accuracy, true positive rate (TPR) and true negative rate (TNR) of 99%, 98.88% and 96.03%, respectively, for DSO-1 dataset. The proposed method reached the performance improvement of 24.49%, 8.92%, 6.72%, 4.17%, 0.25%, 0.13%, 0.06%, and 0.06% in comparison to the existing methods, such as Kee and Farid's, shape from shading (SFS), random guess, Bo Peng et al., neural network, FOA-SVNN, CNN-based MBK, and Manoj Kumar et al., respectively, in terms of accuracy.
Originality/value
The Taylor-ROA is developed by integrating the Taylor series in rider optimization algorithm (ROA) for optimally tuning the DeepCNN.

Abstract
This study examines the impact of perceived community alienation on levels of self‐reported mastery and motivation for proactive law enforcement for 272 police officers from 11 law enforcement agencies in a large Southeast Michigan County. Also, it investigates the impact of three highly publicized “anti‐police” judicial verdicts (i.e. Rodney King, Malice Green, and O.J. Simpson) on the predicted alienation‐mastery‐proactive enforcement relationship. Results support the study’s major hypothesis that, as officers’ perceived level of alienation increases, they will report less mastery, and express less willingness for proactive enforcement efforts. One regression model confirms the study’s second hypothesis that the inverse relationship between alienation and motivation for proactive enforcement increases significantly following the “anti‐police” judicial verdicts.

Abstract
The use of celebrities, and particularly athletes, to influence consumers and sell products is not a new practice, but one that is gaining considerable steam in the sports marketplace. However, many academics and practitioners have long questioned the means by which celebrity endorsement is measured and evaluated. Through the use of validated surveys among US students and the inauguration of the Celebrity-Hero Matrix (CHM), some of their questions are answered. Being labelled a 'heroic' athlete does, it seems, have tremendous power for marketers, and provides endorsement clout for the athlete.

Abstract
The proper identification of consumers' risk perception, fear and panic behaviour can help managers to limit consumers' irresponsible behaviour, develop safer shopping experiences and attract consumers to physical stores. Indeed, the risk of contagion might result in shopping anxiety and limit consumers' propensity to visit the physical stores. This chapter aims at supporting retailers by providing a deep understanding of how the uncertainty and risk perceptions coming from emergency awareness impacts consumers' behaviour. Attention is solicited towards new retail strategies and practices to mitigate these consequences.

Abstract
Luxury branding, in the context of tangible luxury consumables, has received academic attention. But the notion remained inconclusive in the context of consumption of luxury intangibles. The travel setting provides an excellent backdrop to explore the complex cognitive process of assigning meaning to the relationship between travellers and luxury travel brands. The shifting image of luxury consumption from elitism to mass aspirational, too, needs to be studied for its transformative implications. The chapter focused on developing a brand relationship scale, namely, TraveLux, in the context of luxury travel consumption and tested its robustness to explain the shared sentiments and emotions of travellers, engaged in luxury travel, across social media. The chapter identifies a four construct instruments capturing the essence of immersive experience, ethnocultural acculturation, passion and excitement and self-congruence as a seedbed of luxury brand affinity for travellers. TraveLux was also found to capture the shared experience of travellers consuming luxury travel brands, thereby establishing a synch between the instrument constructs and manifested human cognition in real-life situations. The study expanded on the volume of literature pertaining to luxury branding in the context of product-oriented industry and addresses the existing void in understanding traveller–brand relationships in luxury travel contexts. The study implicates a theoretical change in branding concept in perceiving luxury brands as price-based exclusivity to a transformative cultural experience. Further extrapolations of the study could be made by incorporating subtle behavioural patterns of travellers in perceiving luxury and subsequent evocation and predisposition towards decision-making.
