Purpose: Grandparents are common providers of childcare within the Caribbean region. Yet research on the implications of grandparent caregiving for older adults’ well-being is limited. This study examined gender differences in the relationship between grandparent caregiving and the life satisfaction of older adults in Jamaica.

Methodology: Using a sample of 1,622 grandparents 60 years and older drawn from the 2012 study “The Health and Social Status of Older Jamaicans,” we estimated binary logistic regression models to examine the association between the frequency of grandparent caregiving and the life satisfaction of grandparents.

Findings: Grandmothers were more likely than grandfathers to provide care. We did not find a statistically significant gender difference in the life satisfaction of caregiving grandparents. Yet, gender differences in the patterns of association between grandparent caregiving and life satisfaction were evident. Among grandmothers, both occasional and regular caregiving was associated with higher life satisfaction relative to non-caregivers. Among grandfathers, however, only regular caregiving was positively associated with life satisfaction.

Originality: This is the first population-based study within the Caribbean to examine gendered patterns of grandparent caregiving and the association with grandparents’ well-being. The findings of this study suggest that grandparent caregiving is beneficial to the well-being of older Jamaican men and women. This study challenges assumptions of gender norms that typically do not position men to be involved in caregiving roles, and to derive satisfaction from such roles, within Caribbean households. The authors suggest more attention should be given to interventions to encourage men to be actively involved in family caregiving.

Two prospective synchronous regional audits involving three tertiary plastic surgery units in mixed service hospitals were carried out to study delays in the management of emergency patients and their possible causes. Each audit was over a one‐month period. These prospective studies investigated “fasting times” (the length of time that an individual patient was fasted prior to definitive management) and “injury to theatre time” (the time span from the time of injury to the time of surgery for patients going to the operating theatre). Results are analysed and discussed and recommendations for improvement are offered.

Calls for corporate social responsibility are widespread, yet there is no consensus about what it means; this may be its charm. However, it is possible to distinguish the fi duciary obligations owed to shareholders, as expressed by Milton Friedman, from all other paradigms of corporate responsibility. Friedman maintains that: “ ...there is one and only one social responsibility of business‐to‐use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the game, which is to say, engages in open and free competition, without deception or fraud.” All other paradigms argue that corporations have social responsibilities that extend beyond the pursuit of shareholder benefits to stakeholders. The list of cited stakeholders is ill‐defined and expanding, including non‐human animals and non‐sentient things. This paper defends the intellectual and ethical merits of fiduciary duties, and compares and contrasts it to the stakeholder paradigm. The fiduciary duty to firms’ owners is the bedrock of capitalism, and capitalism will wither without it.

Although increased social time is associated with healthier lifestyles, autistic people often present in therapy with social time difficulties. Given the growing interest in digital interventions and their applicability for autistic individuals, a social time app could be beneficial to support autistic people to manage social time, but there is limited research in this field, especially that which involves people with lived experience. The purpose of this study was to use co-production to conduct consultations with expert clinicians about the relationship between autism and social time, and the future development of a smartphone app to monitor and support social time in autistic people.

A qualitative methodology investigated clinicians’ views on the relationship between autism and social time and potential development of a social time app. Clinicians (N = 8) participated in semi-structured interviews facilitated by a researcher with lived experience of autism.

Participants were psychologists and psychotherapists from a specialist autism service. Thematic analysis identified factors associated with social time, such as differences with neurotypical populations, need for balance with non-social time and gender differences. According to participants, advantages of social time were connecting with people and forming relationships, whereas challenges were limited social skills, anxiety and anger and frustration. Suggested features of an app were a user-friendly design, psychoeducational components and prompts and reminders. Potential advantages of the app were support outside of therapy, support in therapy and monitoring emotional responses, whereas challenges were task completion and personalising content.

Findings reinforce the importance of a balance between social and non-social time for autistic people, which could be monitored and supported using a social time app. Clinicians could incorporate use of this app within psychological therapies to support emotional regulation and general functioning.

BUSINESS leaders recur again and again in their public utterances to the difficulty of obtaining enough recruits of suitable calibre. What they have in mind, as Mr. David Barran, chairman of Shell Transport, implied recently, is university graduates. ‘What I am really pleading for,’ he said, ‘is a stronger bridge between education and industry, starting as far back as the sixth form and extending across the student years at university, helping the graduate to choose a career that will employ his potential to the best advantage.’

In modern cloud services, resource provisioning and allocation are significant for assigning the available resources in efficient way. Resource management in cloud becomes challenging due to high energy consumption at data center (DC), virtual machine (VM) migration, high operational cost and overhead on DC.

In this paper, the authors proposed software-defined networking (SDN)-enabled cloud for resource management to reduce energy consumption in DC. SDN-cloud comprises four phases: (1) user authentication, (2) service-level agreement (SLA) constraints, (3) cloud interceder and (4) SDN-controller.

Resource management is significant for reducing power consumption in CDs that is based on scheduling, VM placement, with Quality of Service (QoS) requirements.

The main goal is to utilize the resources energy effectively for reducing power consumption in cloud environment. This method effectively increases the user service rate and reduces the unnecessary migration process.

As a result, the authors show a significant reduction in energy consumption by 20 KWh as well as over 60% power consumption in the presence of 500 VMs. In future, the authors have planned to concentrate the issues on resource failure and also SLA violation rate with respect to number of resources will be decreased.

The aim of the study is to systematically map the articles published in the area of organic food value chain. Many articles have been published in various domains of organic food value chain, but no significant study has been found related to the systematic mapping of literature.

This study relies on secondary data. Articles from Scopus and Google Scholar databases between January 1, 1990, and July 10, 2021, have been considered. On the basis of inclusion criteria, 56 articles have been analysed in this systematic mapping study.

This study describes the geographical coverage, the methodologies used, sector/industry-specific context of the articles and scope the for future research. Five clusters were identified through co-occurrence analysis: (1) “organic agriculture and sustainable value chain” (2) “organic farming and food value chain,” (3) “organic value chain and sustainable development,” (4) “organic value chain and environmental impact” and (5) organic value chain and profitability.

The study considers only articles published in Scopus and Google Scholar with some specific keywords related to the value chain and organic food industry. Future studies are encouraged by considering a wide range of keywords with a larger data set.

To the best of the author's knowledge, this study is the first to have a systematic mapping of literature on the organic food value chain.

Surface pretreatment of iron and its alloys to remove stains and inorganic contaminants on the metal surface undergoes dissolution by virtue of the strong acidic media thereby increasing its susceptibility to corrosion. The purpose of this study is to explore the corrosion mitigation prospects of green corrosion inhibitors on mild steel surface.

Corrosion inhibition performance of Garcinia gummi-gutta leaf extract (GGLE) was explored against mild steel in 1 M HCl solution using the weight-loss method, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) techniques. Surface characterization was carried out to study the mechanism of inhibitor action.

The concentration of GGLE varied from 100 to 6,000 ppm and the result indicates that corrosion inhibition efficiency was amplified by raising the inhibitor concentration. The maximum inhibition efficiency was 82.2% at 6,000 ppm concentration. EIS results show the development of a protective layer of inhibitor molecule over the metal surface and PDP demonstrates that the inhibitor operates as a mixed-type inhibitor. Scanning electron microscopy and atomic force microscopy were executed to assess the surface morphology and roughness, respectively.

To the best of the authors’ knowledge, so far, no studies have been reported on the corrosion inhibition performance of GGLE which is rich in many bioactive components especially hydroxyl citric acid. This work encompasses the corrosion inhibition capability of GGLE against mild steel in an acidic medium.

Scientists have long suspected that deficiencies of folic acid may contribute to defects such as spina bifida and hydrocephalus, both known as neural tube defects. Twenty‐five years ago it was suggested that deficiency of folic acid, one of the B vitamins, might be the culprit. Now it has been proved.
