Abstract

Purpose

The diagnosis of psychosis in individuals with autism spectrum disorder (ASD) poses a unique clinical challenge. The presence of intellectual disability (ID) further complicates the diagnostic picture. Reliable and timely diagnosis of psychosis in such individuals minimises the duration of untreated psychotic symptoms and the subsequent impact on the quality of life of the patients concerned. The paper aims to discuss this issue.

Design/methodology/approach

The authors present four patients with psychosis, ASD and ID, who have received care within forensic mental health and ID settings. These examples demonstrate the interaction between these conditions, as well as issues pertaining to diagnosis and management.

Findings

In all four patients, sustained use of antipsychotic medication was objectively associated with an improvement in psychotic symptoms and quality of life. In instances where autistic phenomena were accentuated upon development of psychosis, such features returned to the baseline levels evident prior to the onset of psychosis.

Practical implications

The discussion and related case examples could improve the understanding of the possibility of psychosis in individuals with ASD and ID, and increase awareness of this diagnostic possibility among healthcare professionals.

Originality/value

This is the first published case series illustrating the challenges of diagnosing psychosis in individuals with ASD and ID.

Abstract

Purpose

This paper aims to clarify the relationship between mechanical behaviors and the underlying geometry of periodic cellular structures. Particularly, the answer to the following research question is investigated: Can seemingly different geometries of the repeating unit cells of periodic cellular structure result in similar functional behaviors? The study aims to cluster the geometry-functional behavior relationship into different categories.

Design/methodology/approach

Specifically, the effects of the geometry on the compressive deformation (mechanical behavior) responses of multiple standardized cubic periodic cellular structures (CPCS) at macro scales are investigated through both physical tests and finite element simulations of three-dimensional (3D) printed samples. Additionally, these multiple CPCS can be further nested into the shell of 3D models of various mechanical domain parts to demonstrate the influence of their geometries in practical applications.

Findings

The paper provides insights into how different CPCS (geometrically different unit cells) influence their compressive deformation behaviors. It suggests a standardized strategy for comparing mechanical behaviors of different CPCS.

Originality/value

This paper is the first work in the research domain to investigate if seemingly different geometries of the underlying unit cell can result in similar mechanical behaviors. It also fulfills the need to infill and lattify real functional parts with geometrically complex unit cells. Existing work mainly focused on simple shapes such as basic trusses or cubes with spherical holes.

Abstract

Purpose

Part quality inspection is playing a critical role in the metal additive manufacturing (AM) industry. It produces a part quality analysis report which can be adopted to further improve the overall part quality. However, the part quality inspection process puts heavy reliance on the engineer’s background and experience. This manual process suffers from both low efficiency and potential errors and, therefore, cannot meet the requirement of real-time detection. The purpose of this paper is to look into a deep neural network, Convolutional Neural Network (CNN), towards a robust method for online monitoring of AM parts.

Design/methodology/approach

The proposed online monitoring method relies on a deep CNN that takes a real metal AM part’s images as inputs and the part quality categories as network outputs. The authors validate the efficacy of the proposed methodology by recognizing the “beautiful-weld” category from material CoCrMo top surface images. The images of “beautiful-weld” parts that show even hatch lines and appropriate overlaps indicate a good quality of an AM part.

Findings

The classification accuracy of the developed method using limited information of a small local block of an image is 82 per cent. The classification accuracy using the full image and the ensemble of model outputs is 100 per cent.

Originality/value

A real-world data set of high resolution images of ASTM F75 I CoCrMo-based three-dimensional printed parts (Top surface images with magnification 63×) annotated with categories labels. Development of a CNN-based classification model for the supervised learning task of recognizing a “beautiful-weld” AM parts. The classification accuracy using the full image and the ensemble of model outputs is 100 per cent.

Abstract

Purpose

The purpose of this paper is to describe key policy and practice issues regarding a significant subgroup of people with intellectual disability – those with offending behaviour being treated in forensic hospitals.

Design/methodology/approach

The reasons why psychiatrists continue to be involved in the treatment of people with intellectual disability and mental health or behavioural problems and the factors that may lead to patients needing hospital admission are examined. Using two illustrative examples, three key questions – containment vs treatment, hospital care vs conditional discharge and hospital treatment vs using deprivation of liberty safeguards usage in the community are explored.

Findings

Patients with intellectual disability, mental health problems and offending behaviours who are treated within forensic inpatient units tend to have long lengths of stay. The key variable that mediates this length of stay is the risk that they pose to themselves or others. Clinicians work within the framework of mental health law and have to be mindful that pragmatic solutions to hasten discharge into the community may not fall within the law.

Originality/value

This paper makes practical suggestions for the future on how to best integrate hospital and community care for people with intellectual disability, mental health and offending behaviours.

Abstract

Purpose

The 11th revision of the International Classification of diseases which sets global standards for defining, reporting and managing health conditions is under way. The International Classification of Diseases (ICD) underpinning principle of clinical utility is currently poor for persons with Disorders of Intellectual Development (DID) and mental disorders. This impedes access to healthcare resources; services and social inclusion thereby further aggravating their vulnerability. The purpose of this paper is to present a critical overview and evidence informed recommendations within the context of an international collaborative programme, undertaken by the Faculty of Psychiatry of Intellectual Disability, Royal College of Psychiatrists, UK with support from the World Health Organisation (WHO).

Design/methodology/approach

The authors carried out: first, a systematic review (SR) of literature, using PRISMA guidelines regarding the reliability, validity and utility of the ICD-10/Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnostic criteria in people with DID (PWDID); second, a national and international consultation exercise with partners, stakeholders and experts; third, a multicentric survey of problem behaviours in PWDID; and finally, information dissemination/dialogues including presentations and workshops at key scientific events, consultation networking, data gathering and consensus building.

Findings

The SR revealed a dearth of robust studies – most consisting of weak research methodologies. Significant difficulties were highlighted regarding the application of diagnostic criteria in the current classificatory systems – particularly in people with severe/moderate DID. Recommendations supported the introduction WHERE APPROPRIATE of modifications based on observed phenomena (signs) in PWDID in lieu of reported symptoms to facilitate DIAGNOSIS AND better access to healthcare and the community. Heterogeneity precluded quantitative pooling and meta-analysis. The consensus building exercise globally revealed that problem behaviours were the commonest reasons for referral to healthcare services with significant numbers without a diagnosed mental disorder being prescribed psychoactive medication.

Research limitations/implications

The consensus gathering exercise WAS SELECTIVE AND did not cover all of the 194 member states of WHO due to resource and time constraints and this constitutes the main limitation of our study. Based on the SR and expert consensus, the authors submitted evidence informed pragmatic proposals to the WHO aimed at addressing the shortcomings of the ICD-10. The key recommendations focused on improving clinical utility within the context of epistemic iteration which would consolidate and strengthen the future evidence base. It was also recommended that self-injurious behaviour should form a standalone sub category in view of its relevance for healthcare services and resources which underpin clinical utility.

Practical implications

The ICD-11 is a global, multidisciplinary and multilingual development for public health benefit with 70 per cent of the world's health expenditures assigned using this system for resource allocation. Currently mental disorders in PWDID can be misinterpreted, unrecognised and under reported resulting in barriers to access to treatment and healthcare resources. Conversely disorders may be over diagnosed when the inherent discrepancies between the chronological age and the developmental level of functioning are not considered. Conclusions and recommendations from this study will result in better diagnosis of mental disorders and healthcare resources in this population.

Social implications

PWDID are a vulnerable sector of the population with an increased prevalence of mental health problems who are marginalised and discriminated by society. Early detection, treatment and management of these conditions will prevent further decompensation and stigmatisation.

Originality/value

To the best of the authors knowledge this is the first comprehensive, large-scale study which evaluates the ICD classificatory system within the context of clinical utility for PWDID, including experts and stakeholders from both lower/middle- and high-income countries. The international consultation/consensus building process culminating in the formulation of evidence informed recommendations, aimed at improving the clinical utility of the ICD-11 for this population, has the potential to improve access to appropriate healthcare and treatment and consequent enhancement of their quality of life.

Abstract

The Olympic Gold Quest (OGQ) was founded as a Non-profit to support Indian athletes in their quest to win Olympic Gold medals by bridging the gap between the best athletes in India and in the world. The support from OGQ has been instrumental to India in winning its highest number of medals at any summer Olympics. Buoyed by this success, OGQ has set up a target of achieving eight Olympic medals at the 2016 Rio Olympic Games. With OGQ relying on donations to support the athletes, the challenge is to market the Olympic cause by creating, communicating, and delivering the right offering for its donors.

Abstract

Purpose

Milk cake is a well-renowned khoa-based dairy product in India, produced either from the buffalo milk or using a specific danedar variety of khoa. Under ambient conditions, shelf-life of milk cake is generally up to 3–4 days, whereas under refrigeration conditions, it can last up to 12–14 days. Therefore, the present study aims to evaluate the effect of modified atmosphere packaging (MAP) to enhance the shelf-life and keeping intact freshness of milk cake under refrigerated conditions (4 ± 2 °C).

Design/methodology/approach

Different gas concentrations of N2 and CO2 (70:30, 50:50 and 90:10) were used as a treatment, whereas control samples were kept under atmospheric air composition. The product was examined for sensory, physicochemical and microbiological parameters at weekly intervals.

Findings

The physicochemical and microbiological attributes displayed gradual elevation with progressive storage period in all the samples. However, the overall sensory profile of the product remained acceptable for a longer duration. Most of the quality parameters in control declined more rapidly with a shelf life of 14 days, in comparison to MAP packed samples, where gas flushing with the ratio 70:30 was found to be best suited for extending the shelf life of milk cake up to 28 days at refrigeration temperature.

Originality/value

To extend the shelf life of milk cake, modified atmosphere was provided with different gas ratios to reach a best-suited environment for sensory, storage life and proximate parameters.

Abstract

Purpose

The literature review of post-harvest supply chain (PHSC) losses is carried out and analyzed in this paper followed by bibliometric analysis of the literature.

Design/methodology/approach

The literature survey is performed across various dimensions such as PHSC losses, PHSC risks and PHSC sustainability (waste management and waste reduction). One hundred thirty research articles during the period of 1989–2020 were considered for the review.

Findings

The PHSC losses have been identified in this literature survey. The calculation and mitigation strategies stated by various researchers in the literature are addressed. The important loss mitigation dynamics are also presented to reduce the PHSC losses and to improve food availability.

Research limitations/implications

The major focus is given on the PHSC of agriculture produces. However, research articles from fish and meat supply chain are excluded as they follow a different perishability curve.

Practical implications

The current work will add value to the agriculture supply chain literature, provide a platform for PHSC losses and provide assistance/guideline toward loss calculation, loss mitigation, improved rural employability, improved rural entrepreneurship and improved revenue generation.

Social implications

The performed research will assist the researchers, entrepreneurs and farmers to understand the current scenario of food wastage at different stages of the supply chain better. It will provide the guidelines for calculation and mitigation of various stated PHSC losses. This study will be helpful to enhance food availability and food security in post-coronavirus crisis.

Originality/value

The paper explores and highlights PHSC loss calculations and mitigation strategies to identify the postharvest loss situation and better utilization of fresh produces.

Abstract

Purpose

This study aims to examine the influence of five sports celebrity personality (SCP) attributes – attractiveness, expertise level, credibility, trustworthiness and character – on consumers' purchase intentions (CPI). It identifies celebrity brand congruence (CBC), endorsed brand celebrity (EBC) and transfer of brand image (TBI) as antecedents of CPI.

Design/methodology/approach

The purposive sampling technique was used to collect the data from 838 respondents. This study developed a multidimensional construct for SCP. The covariance-based structural equation modeling (SEM) technique was used to examine the relationship between SCP and the endorsed brand. The study used CBC as a mediator and EBC and TBI as partial mediators. The direct and indirect effect of SCP on CPI was investigated using CBC, EBC and TBI as mediators.

Findings

This study supports the importance of three antecedents (i.e. CBC, EBC and TBI) on CPI. It finds congruence across SCP and CBC variables, and a positive impact of SCP on EBC and TBI variables. Also, it exhibits a significant direct effect of CBC on EBC and TBI, whereas the direct effect of CBC on CPI is not substantial. The indirect effect of CBC through mediating variables EBC and TBI found to be significant.

Research limitations/implications

This study concludes that sports celebrity endorsement is essential to transfer the positive celebrity image to the endorsed brand image. However, it is not merely sufficient to influence the buyers' purchase conduct; the brand credibility additionally assumes to take a role in changing their behavioral intentions.

Originality/value

This study contributes to the sports marketing literature by its novelty in analyzing the sports celebrity personality at a multidimensional level. It uses SCP's different attributes as one construct and studies its impact on CPI by taking CBC, EBC and TBI as mediators. The results of this study equip sports management professionals with the knowledge to build better long-term relationships with consumers.
