Abstract
The aim of the present paper is to present certain existence theorems for stochastic control systems whose state variables, χ(t;ω), are continuous functions from the set R+ = {t;t ≥ 0} into the space L2(Ω, A, μ). That is, for each t R+, χ(t;ω) is a vector‐valued random variable whose second absolute moment exists. U = μ(t), the admissible controls, are taken as measurable functions of t only. It is assumed that the initial time is fixed but allow the terminal time tf(ω) to vary with ω∈Ω. The usual space constraints and boundary conditions are also allowed to vary with ω∈Ω. The cost functional is taken to be a continuous functional over a suitable class of continuous functions.

Abstract
Education policies in the United States reinforce social stratification by prioritizing and normalizing middle-class whiteness in schools (Leonardo, 2007; Picower, 2009). The teacher labor market has also become more feminized, making white middle-class women paragons of exemplary educators (Rury, 1989; Tolley & Beadie, 2006). These sociopolitical and historical factors continue to play out in the current U.S. education workforce where 80% teachers are white and 76% of teachers are female (Hussar et al., 2020). Meanwhile, student demographics are shifting with students of color comprising over 50% of the public student population (de Brey et al., 2019). Diversifying the educator pipeline is a well-documented strategy to improve educational outcomes for all students, specifically students of color, and to achieve greater equity and inclusion in public education. However, the retention and promotion of educators of color remains a critical and complex issue.
Thus, looking at the intersection of race and gender in the education workplace, the purpose of this chapter is to highlight the experiences and expertise of women K-12 educators of color to identify best practices for career development. Applying Psychology of Working Theory (PWT) and utilizing modified meta-synthesis methodology, the chapter highlights the experiences of Black, Latinx, Asian American, and Indigenous/Native American women K-12 principals and superintendents to (1) thematize and conceptualize how women of color define their work in education spaces through a PWT lens and (2) understand how PWT themes can illuminate ways to build more diverse and inclusive career pathways for women of color leaders.

Abstract
Purpose
Many studies have examined pre-diploma students' backgrounds and academic performance with results showing that some did not achieve the expected level of competence. This study aims to examine the relationship between students’ demographic characteristics and their academic achievement at the pre-diploma level using machine learning.
Design/methodology/approach
Secondary data analysis was used in this study, which involved collecting information about 1,052 pre-diploma students enrolled at Universiti Teknologi MARA (UiTM) Pahang Branch between 2017 and 2021. The research procedure was divided into two parts: data collecting and pre-processing, and building the machine learning algorithm, pre-training and testing.
Findings
Gender, family income, region and achievement in the national secondary school examination (Sijil Pelajaran Malaysia [SPM]) predict academic performance. Female students were 1.2 times more likely to succeed academically. Central region students performed better with a value of 1.26. M40-income students were more likely to excel with an odds ratio of 2.809. Students who excelled in SPM English and Mathematics had a better likelihood of succeeding in higher education.
Research limitations/implications
This research was limited to pre-diploma students from UiTM Pahang Branch. For better generalizability of the results, future research should include pre-diploma students from other UiTM branches that offer this programme.
Practical implications
This study is expected to offer insights for policymakers, particularly, the Ministry of Higher Education, in developing a comprehensive policy to improve the tertiary education system by focusing on the fourth Sustainable Development Goal.
Social implications
These pre-diploma students were found to originate mainly from low- or middle-income families; hence, the programme may help them acquire better jobs and improve their standard of living. Most students enrolling on the pre-diploma performed below excellent at the secondary school level and were therefore given the opportunity to continue studying at a higher level.
Originality/value
This predictive model contributes to guidelines on the minimum requirements for pre-diploma students to gain admission into higher education institutions by ensuring the efficient distribution of resources and equal access to higher education among all communities.

Abstract
Purpose
Stroke is a leading cause of death and disability in the USA and worldwide. While stroke care has evolved dramatically, many new acute approaches to therapy focus only on the first 3-12 hours. Significant treatment opportunities beyond the first 12 hours can play a major role in improving outcomes for stroke patients. The purpose of this paper is to highlight the issues that affect stroke care delivery for patients and caregivers and describe an integrated care model that can improve care across the continuum.
Design/methodology/approach
This paper details evidence-based research that documents current stroke care and efforts to improve care delivery. Further, an innovative integrated care model is described, and its novel application to stroke care is highlighted.
Findings
Stroke patients and caregivers face fragmented and poorly coordinated care systems as they move through specific stroke nodes of care, from acute emergency and in-hospital stay through recovery post-discharge at a care facility or at home, and can be addressed by applying a comprehensive, technology-enabled Integrated Stroke Practice Unit (ISPU) Model of Care.
Originality/value
This paper documents specific issues that impact stroke care and the utilization of integrated care delivery models to address them. Evidence-based research results document difficulties of current care delivery methods for stroke and the impact of that care delivery on patients and caregivers across each node of care. It offers an innovative ISPU model and highlights specific tenets of that model for readers.

Abstract
Purpose
The purpose of this paper is to explore the following questions. First, what are the experiences of family caregivers in caring for community-dwelling stroke survivors? Second, what services help or do not help the caregivers in managing their caregiving role?
Design/methodology/approach
A qualitative study was conducted with a total of six focus group interviews with 29 stroke caregivers selected using convenience sampling in a local community centre. All interviews were recorded and transcribed for content analysis.
Findings
The results pointed to three main themes working together to facilitate desirable outcomes in caregiving and prevent elder abuse: factors contributing to caregiver stress and factors that have a buffering effect on caregiver stress and unmet needs identified from caregivers’ experiences.
Research limitations/implications
The authors found that there were a number of factors contributing to caregiver stress. The findings matched with the concept that caregiver stress should not be considered as the primary cause of elder abuse. Findings provided information for further research to investigate positive coping and adjustment for stroke survivors, caregivers and their families.
Practical implications
Policy makers and service providers may consider specific policies and tailor-made services to enhance the effectiveness of current practice. The themes emerging from the study could be further reviewed in a longitudinal way to explore the cost-effectiveness, the outcomes and trajectory of interventional programmes.
Social implications
Education would be essential to let the public understand caregivers’ difficulties and needs. Prevention of elder abuse may be approached with a range of risk factors for both perpetrating and being elder abuse victim.
Originality/value
From the findings of the study, the authors found that there were service gaps within policy and interventions. Concrete suggestions for improving the public's attitude and public facilities/transport for the disabled were captured in the study. In addition to personal resilience, caregivers had a strong wish for a supportive environment and services that would facilitate a better caregiving outcome.

Abstract
Surveys confirm that ice can be a vector for gastrointestinal disease, its quality reflecting the water from which it was made. High levels of organisms which indicate hygiene failure, as well as faecal contamination and/or the presence of pathogenic bacteria, viruses, protozoa or cryptosporidia have been found. While potable water is the minimum water quality required for ice production, good hygienic practices are needed for the production and handling of ice. Microbiological standards for ice have not yet been agreed in either Europe or in the UK, but the minima desirable are those required of potable water. Ice should not be consumed unless there is confidence in the hygiene of its production.

Abstract
If child custody decisions are based on erroneous beliefs, family courts may not be acting in the best interests of children. This study examined family court professionals' beliefs about family violence. Respondents (N = 410) of diverse professions, including child custody mediators, evaluators, and therapists, family law attorneys and judges, victim advocates and university students, completed a 10‐item multiple‐choice quiz. Results revealed low rates of correct responding, with respondents correctly answering approximately three out of 10 items on average, based on current research in the field. Overall, response rates were highly consistent with the discredited patriarchal paradigm. Shelter workers and victim advocates had the lowest average score, and men were found to have slightly higher scores than women. More troubling, students' scores were not significantly lower than those of family court professionals. Implications are discussed with respect to decision‐making in the context of child custody disputes.
